Tip of the Week (#003) - Filter Sizes

Filters. How to buy filters if you have lenses with varying filter thread sizes? One approach is to buy the biggest size and any step-rings necessary to adapt them to your smaller sized filter threads. The downside is that fitting a lens hood may become difficult, if not impossible. And if your sizes cover quite a range, perhaps impractical. Another approach is to just buy filters for the largest of your most commonly used lenses and go from there. For most Leica lenses, 46mm is a great size to settle on.
