So I rarely shoot birds and animals these days. Mostly because I feel the e-mount system doesn't really have a lens for that sort of stuff. I know I could go legacy lenses, add tele-extenders, or use LEA adapter with A-mount. I tried them all and I still was pretty annoyed. I just felt like I was using the tip of a hammer as a screw driver. So why this set. Well, while looking at FD lenses at Keh for my A7, I saw this excellent condition Canon FD 70-210 F/4 @ Keh for $40. I bought it, so I wanted to test it. What better place than the back yard. Shots were taken with A7 or A6000. Raw was processed in DXO & LightRoom. There is a lot of cropping since this is only 210mm. I feel the lens has average sharpness at 210 which is the only focal length I shot. It also has ridiculous chromatic aberration when used at F4-5. Again, where I shot at. I spent much more time than usual dealing with this in LR. In the end, I feel it is definitely worth it. I feel with some post work, it can get the job done. Particularly, if someone just needs an occasional tele and doesn't want to invest any real money. You really aren't gonna get much better for $40. BTW - I just noticed the Titmouse shot was with the a6000 SEL55210. I was trying the AF.
