- Probably not. As far as I know, they're all Plasmat type lenses and they
- all perform more or less the same. The Schneider says Apo, but the rest
- aren't really that far off. The Nikkor, in particular, is known for it's
- sharpness and contrast. I have one in 180mm which I used quite a bit. It
- works quite well.

- If angular coverage are the same, how can image circle be different?

- As far as I know, Sinaron-s is actually relabeled Sironar-N. The Sinaron
- may be in DB mount though. So check before you buy. Anyway, they're all
- good enough that they aren't the limiting factor in general. So don't worry
- about this kind of thing too much. (Just my $.02 of course)
