Someone who knows these lenses and tell me differences.
Thank you very much.

I'm not familiar with the RMC 5.6, but I have the AT-X 100-300mm F4.

It is big and heavy, but as with most of the AT-X series, it is a very good performer.

The AT-X 100-300 f/4 is a stop faster, big and heavy as dnas mentions and shows, It also has at least one low-dispersion glass element (hence the SD designation) that helps in correcting chromatic aberration. A good lens. I owned one briefly years ago and wish I never would have sold it.

Thank you very much.
I will see one, FD mount and I think it is not SD. The CA may be more problematic. For the images I saw taken with this lens is very good. Almost like a Prime.

If it's the AT-X 100-300 f/4, it's SD. They didn't make non-SD AT-X 100-300s.

If it's the AT-X 100-300 f/4, it's SD. They didn't make non-SD AT-X 100-300s -- at least not ones with the constant f/4 aperture.

That's correct!!! You can't see on the front of the lens on that picture, but it says "SD" on it.

I have the 5.6 version

VERY handy lens : lightweight / small size / 1:2.3 macro at 300mm !
CA is not a problem
