I picked up a used 500mm reflex (Makinon) in a K-mount. There are some specks on the mirror, but I do get a focus lock indication on my D, which didn't happen on an earlier lens purchase, which I returned.

I can return the lens, but am not unhappy with it's performance so far. Haven't had much light lately to test it with. Took this shot yesterday.

This is a 100% crop from the pic. It was shot handheld, but I was stabilized by a tree.

Thanks, guys. I don't have any experience with longer lenses, so didn't know what to expect from it.

Did you do anything to get rid of the tell tale donuts in the bokeh? You did a good job.

Hi, Daniel

The branch was considerable isolated from the background, so there isn't much that would just be slightly OOF, it is way OOF, so that would minimize the donuts. Ther are a couple in the cropped picture, though. One is just below center, and a couple others near the bottom, just to the left. This picture probably isn't a good example of that. Mostly accident, though - I was just taking a test shot to evaluate the sharpness of the lens.

The big thing is are you happy with the lens? From that picture, I'd say it was a keeper, pretty sharp for a reflex lens, and would be worth hanging on to. Sounds like you know the disadvantages that you get with this type of lens.

Hi Brian,

I've got a Tamron SP500/8 which is considered one of the better of the 500 cats, and I don't see a whole lot of difference in sharpness. I'd say that it's a keeper.

It doesn't get used that often, as I have a couple of better @500mm alternatives, but it still gets a spot in the bag for specific situations.

I traded away my Samyang/Phoenix 500mm f8 mirror lens since I could never get the focus right. Just too much trouble to make it useful for the type of photography I was doing. If you like it, it certainly is sharp.
