One day pops gave me a huge box of 35mm photo equipment he found at a yard sale. I didnÕt know what to do with it till I bought a Photodiox FD to EOS adapter. I just added four new lenses to my kit that have very different characteristics from the two modern lenses I had been using. The new (old) 50mm opens up to 1.8 and blurs the background beautifully. I notice the sharpness falls off dramatically toward the edges of the old lenses. I have heard this was a problem with older lenses but I like the look.Canon stopped making these FD lenses the year I was born, Surprisingly, they have much smoother focus and zoom operation, perfect for video. On top of that the Photodiox adapter lets me operate the iris manually so it can move smoothly instead of in stops. I canÕt wait for a situation where I need smaller than a third stop increment. The fact that I can put focus marks on this barrel has me researching follow focus systems.I am really enjoying the novelty of using these classic tools. When I was a kid I played with my dadÕs old Minolta gear from the same era. However, when I got into photography autofocus, electronic apertures, and zoom lenses were common. It is really fun to look down at the lens and click the aperture into place, and twisting the focus myself has me experimenting with new compositions. All this new glass is a lot to process. There seem to be endless benefits to these lenses. For instance, the 50mm or 28mm primes make my 5D much lighter and less obtrusive for casual photography. I still think most of the time I will be using my 28-105mm with image stabilizer and 72mm circumference. However, I canÕt wait to see what I can do with these relics.
