If you happen to still have in a drawer somewhere some old lenses for film cameras, especially any old macro lenses of good quality, I have a suggestion how to recycle them into the new digital age.
Various cameras can use these old lenses. but recently I have been using an adapter on my Sony NEX F3 camera to mount old manual focus Contax/Yashica mout lenses. It has a feature that is remarkably useful, helpful and quite elegant.
Once you frame your shot, you can press a button to temporarily zoom in to your image to fine tune your manual focusing, there are in fact two levels of peaking zoom. Once you continue depressing the shutter, your full image returns and you can take the shot. This feature is outstanding. Adds just a moment to the taking of a shot and the results are perfect.
The camera uses aperture priority and you get a perfectly exposed shot.
My adapter came thru amazon.ca and cost just $29. There is a large number of adapters for the various lenses from various manufacturers.
I imagine all the NEX cameras have this feature. The F3 is entry level and can be purchased for $400-450. Shop around. I got mine thru a special sale item from Staples.
It is very satisfying to be able to use effectively those fine old, high quality optics from film photography days.
