Originally posted by djb47 I'll go with the Industar 50-2. For a 42 year old piece of glass this lens in surprisingly sharp and more than capable when I get the focus right. Overall, a nice little lens.
Stunning photo! Colors are great. Contrasts are strong without going over the top. Concept is original. The lens is shown off fabulously.
My lens is another story. I have great trouble focusing. The depth of field is razor thin. I shoot birds in my backyard which is naturally low in light, contrast, and begs for a tripod when the subject matter flits about too much to allow one. So I have been less than thrilled at the technical excellence of my bird photos.
My other use for the lens is lunar photography. That has proven disastrous. My tripod and head are a bit underclassed, making focus all the harder to achieve. And the lens in general seems to lose resolution as I approach infinity focus. I discovered through this forum that the lens requires a rear filter to function properly. No filters came with my purchase, I bought a Hoya Evo Antistatic 40.5mm Filter for the rear filter element. The use of the Hoya made a tremendous improvement over using no rear filter at all.
So I am wondering, what am I doing wrong? Is there another trick I am missing? Is my Hoya not up to the job? Am I expecting too much from the lens? Is this a classic case of user error?
Any advice or observations will be most appreciated.
