People have grown tired of shooting through the middle of their lenes image
circles years ago. Once you get your lenses back you don't want to give them
up again. No I don't want my 24 turned into a 35. I want it to be what it
was designed to be. And why I spent all that money for it is because its
able to do what it was designed to do. Shoot nicely right out to the edges.

The only considerable plus to using full frame glass on cropped amateur
bodies is if you are using very long glass that glass gets a bit longer a
thing which rarely hurts in that context. And in good light not low light
that can be a help shooting your kids basketball games or birds

I also have a smilax 50 and 35, but my goal is to travel light.
