Introduction

Despite being the online leader in information and images leading up to - and announcing - the Leica T (Type 701) system and lenses on April 24, 2014 in Berlin... It took many requests and three full months to finally get a hold of the new Leica T (Type 701), Summicron-T 23mm f/2 ASPH (35mm), Vario-Elmar-T 18-56mm f/3.5-5.6 ASPH (28-85mm) and Visoflex (Type 020) for review. Of course, by now everyone's already had a chance to review (or read one) on this new system. So we're not going to spend much time on one now. Instead, we're going to look at actual use - the shooting experience, if you will. Unfortunately, we only had two weeks to do so.

During our idle wait for a review system, we compared the Fujifilm X-T1 vs. the Leica T and also looked at its Bauhausian simplicity of design. We'd recommend checking both out for additional information and background!

The Camera

The Leica T itself, as you're aware - is machined from a solid block of aluminum, which is then hand-polished for 45 minutes by hand (see video below). Perhaps a stroke of marketing genius, this "most boring ad" got everyone talking - both good and bad... From there, it's finished in either a silver or black anodizing. It may sound excessive, but we have to say - the body is gorgeous. It's a perfectly formed work of art and design.

Built according to the traditions of the art of engineering. The Leica T Camera System is the world’s first camera with a body made completely of aluminium. Machined from a single block of solid metal and polished by hand for 45 minutes. The outcome: the innovative and groundbreaking unibody – unique in both look and feel.

Flipping around to the back, one can't help but notice the monolithic black, glass-covered LCD screen. It looks like an iPhone was seamlessly integrated into the camera body, and you wouldn't be far off in thinking that. Leica has integrated the guts of the X system cameras (sensor, shutter, other electronics, etc.) with a touchscreen LCD for control, rather than utilize buttons and dials as with so many other cameras these days. In fact, there are very few mechanical controls at all... Exactly five. An on/off/flash switch with shutter release, a movie record button and two thumb dials (seven if you count the lens and battery release buttons).

A large touchscreen. Four haptic control elements. A logically designed, intuitive und ergonomic handling concept. The Leica T needs nothing else. Never before has it been so easy to understand a camera. And to use it. Created to let you concentrate on your pictures. To maximise the joy of photography. To get the perfect picture.



The camera itself feels extremely solid and tight... Dense, yet in spite of the aluminum, somewhat heavy. With the exception of a few edges and corners, it's very smooth to the touch. Almost silky. It's worth pointing out that the grip portion on the front of the camera is the sole method of holding onto it; there's no rubber anywhere, no thumb rest in the back. The camera doesn't feel like it'll fall out of your hands though. While the body itself is fairly light, with a lens and especially the Visoflex mounted as well, you'll want to support the camera with your left hand - and additionally want to consider the Leica T-Snap case for a better grip. While the latter is certainly optional, consider that the body of the camera will be quite cold to the touch in the winter months, being made of aluminum. There's no leatherette as on M cameras. The black T, conversely, will likely get fairly hot exposed to the sun.

Leica T Carrying Strap


The strap, simply called the Carrying Strap ($79 USD), is an object Henry Ford would be proud of, as the saying "you can have any color you want, so long as it's black" is not far off. While it does come in four colors (black, white, melon-yellow and orange-red, also $79 USD each) it only comes in one length. And because of the unique design in the way it attaches to the camera, also your only choice. We wouldn't count on any third-parties to make a strap for the T. They're made of silicone rubber with a wider section for your shoulder. Very grippy, some stretch - but also a bit of a schmutz magnet. Back to the unique method of attachment - which in and of itself is a wonderful example of engineering. Similar to a headphone plug, each end clicks in securely (and must be removed with a push pin). It allows full 360º swiveling and rotating. The ends of the strap are a bit hard-edged, so it's sometimes a bit uncomfortable between the fingers, but not overly so. What's most frustrating is that it comes in one length only, a middle of the road one at that - it'll work well around your neck but less so slung around your neck and shoulder. It's too short for the latter - especially if wearing a coat or jacket. Worse yet, being of such a grippy silicone rubber, it won't smoothly slide around for use. Granted, there is a Wrist Strap and Leather Holster available as well, if you'd rather.

Leica T Configurations

The silver version certainly makes a statement, showing off the beautiful shape and finishing of the body. However, being the lenses are only available in black, unlike their M brethren, we can't help but think the black version makes for a more cohesive looking camera. Especially if you add the Visoflex or flash, as they're also only available in black. If you're looking to express yourself, you can add a generous splash of color not just with the Carrying Strap and matching T-Snap ($79 USD) case, but also a T-Flap ($50 USD) cover for the rear that protects the LCD. All are made of similar silicone rubber.

During our testing, the camera displays (both LCD and Visoflex) glitched out - the screen image froze and randomly whited out or showed a gauze-like effect. Moving our eye away from the Visoflex and back made things jitter but not improve. Powering the camera off and on again did not really help either. Taking the battery out and putting it back in also didn't work, which was odd. Finally, forcing a switch between EVF and LCD several times got things back on track, eventually. There's either a bug in the firmware or the hardware in this circuit. Sadly, this happened a couple of times on us within an hour, during which time the camera was essentially unusable!

Leica T as Reviewed

Speaking of the LCD/Visoflex - one thing that annoyed us greatly was the fact that there's no way to turn off the image review! The shortest duration you can set is one second. This would almost be okay if you could half-press the shutter button to dismiss it, but you can't. You're forced to look at an image review in between shots, losing 1-2 seconds between each! Like viewfinder blackouts of (D)SLRs, you'll miss shots because you can't see what's going on in the scene.

The camera was able to set exposure quite accurately in all modes, and the auto white balance worked well in most situations as well, even tricky mixed daylight/tungsten shots - though sometimes it went a bit towards the colder side in such cases. Outside in daylight it was essentially spot-on every time.

The Lenses

Provided with the camera were the only two lenses available at this time - the Summicron-T 23mm f/2 ASPH (35mm) and Vario-Elmar-T 18-56mm f/3.5-5.6 ASPH (28-85mm). At a later, so far undisclosed time, Leica has promised to release an APO Vario-Elmar-T 55-135mm 3.5-5.6 ASPH (80-200mm) and Super Vario-Elmar-T 11-23mm f/3.5-4.5 ASPH (17-35mm) lenses. The lenses are black, and a mix of anodized aluminum and plastic. They feel solid, the controls very smooth and well damped. But they do not feel dense like M lenses do, especially the silver on brass versions. The hoods are surprisingly robust plastic and utilize a bayonet mounting system. They rotate and catch quickly, but you'll need a fairly firm grip to click-lock/unlock them. This was a little strange at first; but rest assured - they're on there good. They don't rattle, but they are just a tiny bit on the looser side.

While the 18-56mm lens is a fairly reasonable and expected size, especially considering its relatively slow speed - the 23mm seems larger than it needs to be. While the lenses have manual focus (fly-by-wire) rings and the 18-56mm a zoom ring - there are no aperture dials as with Fujifilm XF lenses. So it seems a bit strange that the 23mm is as big as it is; it should be more of a pancake-sized lens in our opinion. This is disappointing, being the smallest lens for the T system - that it will never be a pocketable camera. Especially with lens hoods attached (though they do reverse for storage).

Leica T Lenses

Autofocus is fairly silent and reasonably fast. Though in low light levels, especially the 18-56mm - expect a bit of hunting, if not a failure to lock. This is exasperated by low contrast subjects under the focus point. Which, by the way, can be a single point, a small or large area, controlled by touch (which is pretty neat) or face detection. Switching focus modes - or configuring them - must be done via the touchscreen interface; it's buried a bit by default but can be configured for quicker access. Either way, it involves a fair bit of tapping. Especially if you want to select a focus point... Tap, tap, tap, tap. Every time you wish to move it. When in manual focus mode, you have the option of seeing a (somewhat grainy) 3x or 6x magnified view (of the center only). Unfortunately, a half-press of the shutter does not engage autofocus... A nice way to get "in the ballpark" quickly, after which you fine-tune things manually. Conversely, there's no manual focus available while in autofocus mode either. You must choose one or the other. There's no focus peaking option, unfortunately.

While the 18-56mm zoom is a good compromise between speed and size, honestly, it really is a bit on the slow side. This shouldn't be surprising, considering it's based on the Leica X Vario to some degree - and that lens is no faster. But as a general purpose zoom of the 28-85mm equivalent range, we would've liked to see it top out at f/4. In low light, the AF will hunt/miss quite often (even with the focus assist light) and make the LCD/EVF very laggy as a result. Enabling image stabilization seemed make things even... Trippier. Out and about shooting, it was rather limiting to be forced to use f/5.6 at the long end. With an upper limit of about f/11 before diffraction sets in, that gives you basically two stops of workable range! Sure, one could opt to use the 23mm prime which opens up to f/2... Provided you're okay with giving up the flexibility of a zoom for a 35mm (FF equivalent) lens. There are no other primes coming as far as anyone (other than Leica) knows. Fujifilm by contrast, offers an XF18-135mmF3.5-5.6 R LM OIS WR zoom that maxes out at f/5.6 - but at over twice the focal length! The more comparable XF18-55mmF2.8-4 R LM OIS zoom ranges from f/2.8 to f/4, (almost) a full stop faster at both ends. And it wouldn't increase the size as much as we might be lead to believe (note the additional aperture ring on the Fujifilm XF lens):

Leica T vs. Fujifilm XF Lenses

A quick word about prime lenses - you can use a large range of existing Leica M lenses on the T, and this was certainly Leica's thinking with their Leica T lens roadmap. However, there are three important caveats. The first being the fact that you'll need a (thus-far) unique, Leica-only M-Adapter T at an additional $395 USD cost. Second, Leica M lenses are manual focus only. Finally, there's the cost of the Leica M lenses themselves - the absolute cheapest starts at $1,750 USD (with the most expensive at $10,995 USD)!

As far as performance of the lenses; you shouldn't be too disappointed here, especially with the prime - from wide open to stopped down. At 100% viewing, the details captured were quite decent. Flare resistance was quite good on both lenses, even without hoods. The bokeh of the prime was nice with smooth, round highlights - the zoom was a bit more edgy on occasion, and rather hard to induce at mid to long distances because of the limited aperture range. While neither lens offers a real "macro" mode, you can get reasonably close to your subjects.

It's worth noting that DNG images from the Leica T are coded with profiles that will auto-correct things like vignetting and distortion in Lightroom. If you want to see the images in their raw, unadulterated form, you'll need to use a program like RawTherapee, Capture One Pro or Iridient Developer. There was some brouhaha about this "software fudging" early on, but in truth - so many cameras utilize this technique today. From the Leica M with its coded lenses dating back to the M8 - to the newest cameras from many manufacturers. The lens designers can focus on "hard issues" like sharpness, field flatness, flare resistance, etc. that cannot be corrected after the fact, while the "soft issues" can be dealt with easily in software.

One thing we noticed when processing DNG files from the T is that they don't appear as sharp as out-of-camera JPEGs. Not that this is unusual, as most cameras apply processing to their JPEG output. We prefer not to apply too much sharpening in post however, as it's generally not necessary with the Leica M or Fujifilm X files. But with the T, this doesn't seem to be the case - leading us to believe that the JPEGs receive a heavy sharpening pass. Here's a comparison between the out-of-camera JPEG and DNG, followed by post-processing that got us in the ballpark of the JPEG. The treatment of the JPEG in-camera also altered the colors and such slightly, so during import of the DNG we tried to match the look of the JPEG (Leica's "special sauce") as closely as possible by tweaking the white balance, exposure, contrast, blacks, clarity and saturation sliders (and were still off a bit). Ultimately we applied an Unsharp Mask with somewhat heavy-handed settings of 75/1.0/0 (in contrast, we rarely apply more than 25). What this means is that the lens/sensor isn't as sharp out of the box as the aforementioned Leica M or Fujifilm X combinations. A bit strange, since all lack an AA filter. But this explains our general reaction of "meh" to Leica T images when processing DNGs as we normally do. Here are 100% crops:

The Interface

Now for the interface. Powering the camera on, you'll need to wait a good 3-4 seconds before you can fire off your first shot. Even longer (by about 2 seconds) if you use the Visoflex (see below). Very slow by today's standards! Once the camera's ready, the LCD comes to life and it does look very snazzy. Mostly a black and white affair with red highlights (the Leica colors). No fancy Sonyesque icons here - but that's a good thing, as the UI is far better than anything Sony can muster. It's a very "smartphone-ish" experience in that options and controls are laid out in a grid like app icons - and you can customize them. One thing that's a little frustrating is that when scrolling through the (one long) "menu" of icons, you might inadvertently change a setting here and there while swiping.

As we alluded to earlier, the touchscreen interface is the primary method of configuring and controlling the camera. How does it stack up in actual use? The long and short of it is - it's pretty both pretty cool but somewhat frustrating as well. Not many cameras feature a touchscreen interface, but if you're a part of the Apple iPhone generation, you'll feel right at home with it. Tap, scroll, pinch and expand gestures are all there. As a "photographer" however, the novelty kind of wears off quickly. Even if you customize the icons to your liking for faster access - you have to take the camera from your eye (if using the Visoflex) and fiddle with the screen - a process that requires both hands. Unlike mechanical controls, you'll need to tap, swipe and twiddle your way to compliance with the T. But depending on the mode you're in and how you configure them - the two thumb dials can control a variety of camera functions; aperture, exposure compensation, ISO, etc.

Leica T Touchscreen Interface

While intuitive, the interface is not exactly fluid. There's a bit of lag and jerkiness visible when interacting with it. The worst culprit is during review of your images in playback mode. First, you'll need to swipe down on the screen, which is probably the single most unintuitive control on the camera... Though it makes sense why it is this way, operationally. From there it's more or less fairly standard from a smartphone point of view. Swipe left/right to move between photos, pinch/expand to zoom in and out, tap and double-tap for instant zoom, etc. But the lag in moving between photos is frustrating - especially if you're going through a large number of shots and/or want to traverse a good number of them quickly. And this is with the internal 16GB of storage no less.

As far as the image, the LCD presents a reasonably contrasty image, and generally looks pretty nice. The glass is oleophobic and resists fingerprints remarkably well, even nose prints when using the Visoflex. This is a good thing, as your thumb will rest squarely on the LCD during normal use when holding the camera.

Despite the high-tech approach of the Leica T, it is surprisingly barebones when it comes to "fancy" features. We're not big fans of built-in parlor tricks, being M shooters and all... So don't expect to see HDR or expanded dynamic range options, panoramic mode, filters or anything else. Though there are "film modes" such as standard, vivid, natural (color/B&W) and high-contrast B&W. You can bracket your exposures. Adjust exposure and flash compensation, etc.

Visoflex EVF

Most M shooters will balk at the camera's primary interface being the LCD, and will likely desire the Visoflex (Type 020). While it's purely optional, many will deem it essential (especially in bright light situations). The first problem is that the Visoflex is a $595 USD accessory... Fairly expensive for what it represents. Secondly, and partially because of its GPS integration and other features, it's rather large - it will add a rather sizable hump atop the camera. One nice feature is that it swivels 90º upwards so you can use it as a waist level finder - and it will stay fixed (without detents) at any angle in between. Another nice feature is that it has an adjustable diopter control. In our test however, we maxed out the range on one end - so it barely passed muster in this regard.

The image presented in the Visoflex varies quite a bit, depending on your scene and shooting conditions. When outside in daylight or otherwise well-lit scenes, the image is fairly decent with no lag. When the light levels drop however, things take a turn for the worse - especially when using the relatively slow 18-56mm zoom. As mentioned earlier, the lag/jitter is maddening, as is the digital noise. These issues are magnified when using the Visoflex over the LCD. In any case, the contrast of the Visoflex image is on the low side. Blacks are never truly black at best, and a dull, muddy dark grey at worst. The brightness of the image itself covers a decent range is quite good, though we had to take it off of the default AUTO setting indoors and set it manually to our preference - which was a tad brighter. Going from a bright to a dark area of the scene, even in general, one can discern visible steps in brightness as the camera adjusts; it's not a smooth experience overall. Finally, to make matters worse, the viewing angle is very limited. You must really center your eyeball, lest the image lose more contrast and move to a ruddier mish-mash of tones.

Leica T Visoflex

An important "gotcha" when using the Visoflex is that if you're in Touch AF mode, you can only utilize manual focus with it - as once you put your eye up to the finder, autofocus is essentially disabled! This makes sense as you can no longer see or interact with the LCD, but at least assign AF to a half-press of the shutter button like other modes. Worse, switching AF modes requires a bit of fiddling with the LCD (two to three taps of the finger). Another item to note is that when powering up the camera and holding it up to your eye to take a photo, it will require an additional second or two before the Visoflex displays an image - now you're talking nearly five seconds or so from "on" to "shoot." Your decisive moment is long gone. Finally, perhaps it goes without saying - with the Visoflex mounted, you cannot use an external/hotshoe mounted flash.

The Visoflex is the only game in town, which is disappointing considering its price/performance. An optical viewfinder equivalent it most certainly is not, nor is it on par of some of the competition like the newest from Fujifilm as found in the X-E2 or X-T1 cameras (which set the benchmark for how good an EVF can be; perhaps an unfair comparison by which we're spoiled). The Visoflex will do the job, but it's not great.

Verdict

There's no doubt that the entire T system is well thought-out, forward-thinking and fairly complete, despite the two missing (albeit upcoming) lenses. The accessories and technical equipment available round things out nicely. Each piece is beautifully designed and mostly executed well also. There's not much missing from the system should you decide to buy into it... Which is good, because every item is very unique to the T.

In actual use however, while the camera is quite neat - it may be too frustrating for many in our opinion. There are several showstoppers for us and why personally, we'd probably take a pass on the Leica T until at least the next firmware revision, possibly even until the next hardware revision(s):

  • Image playback/review on rear LCD only - not available on the Visoflex
  • No way to disable review! - minimum time is 1s (you will miss shots during review)
  • You cannot shoot DNG only - only DNG+JPEG (JPEG only is available however)
  • No autofocus possible while in manual focus mode (and vice versa)
  • The built-in flash is rather unimpressive, except at rather close range
  • Image playback and interaction (forwards/backwards) is rather slow
  • Strap option limited to one only (too short and too grippy to swing up to your eye)
  • LCD and EVF very laggy in low light, especially with slow zoom lens and IS enabled
  • EVF has a very narrow angle of view (almost dead center required) and poor image
  • Multiple occasions of camera glitching out and being completely unusable
  • Start-up delay (especially when using the Visoflex) is very frustrating
  • 18-56mm zoom really is rather slow with only one prime lens alternative
  • Extreme cost - our review setup retails for $4,274 USD ($6,224 with the 23mm!)

We really wanted to like the Leica T. While it's a complete, thorough system with fancy hardware and lots of accessories - the lens options are limited and the cost adds up very, very quickly. For the money, and its frustrating shortcomings... We must confess, we're not really fans. Though on the bright side, and we're hoping this is the case - with a good firmware update some of these issues can be addressed. Though some issues can only be solved with hardware. Unless you're really set on the svelte lines of the camera or the novel interface, you can probably do better with other options on the market such as the Fuji X-E2 ($1,199 w/18-55mm lens)... It's much cheaper at almost 1/4th the cost, has far greater functionality/features and a complete range of lenses (including high speed primes). If you prefer to "keep it Leica" and don't need interchangeable lenses, go for the X Vario instead.

Final verdict: A neat camera and a fairly complete system - but it's pricey, needs refinements to be less frustrating and more native lens options. Consider carefully.

Sample Images

These images were shot with the Vario-Elmar-T 18-56mm f/3.5-5.6 zoom lens, at the base ISO of 100. They were minimally post-processed from DNG with our standard import settings (minor boost to clarity, vibrance and saturation) using Adobe Photoshop CC 2014 and Adobe Camera RAW v8.6. Resized with a hint of Smart Sharpen (25/0.3) - while this is our normal sharpening routine, the Leica T really needs about three times as much (75/1).
