Pentax 560mm IS full frame

Hey everyone,

I had a chance to try out the new Pentax 560mm today. I was very curious if a premium telephoto like this would cover a full frame. I didn't really want to wait to develop a roll of film on an old Pentax film camera, so I threw the lens on the full frame Sony NEXVG900 with a Novoflex adaptor. Lo and behold, there is full frame coverage with very sharp edges, even wide open! Both these images were shot at F5.6.

I can confirm this based on film shots, though you can see slight softness in the corners wide-open.

Edit: see post 29.

Will the lens cover the full image circle when IS is active on any future FF Pentax though? We'll have to wait and see, not that it will ever be an issue for me. This is way out of my budget. Thanks for sharing.

I showed my wife the unboxing video from OGL. She said that looks like a neat lens do you want one of those? I said sure, then showed her the price. I won't repeat what she said next but I learned new language.

And another one to the list! Perhaps whenever the FF Camera is released, they'll release updates for all/most of the lenses usage on FF and label it something like D* XX-XX(X) F2.8.

Would be nice if they did something like that, especially if they revamped some lenses to have an rear gasket at least.(Lower end DA lenses would benefit from this, not like it costs a lot, and you're still going to have to pay to shoot in downpouring rain. It would just keep dust out.

Good to know.
But even if there is some softness at f/5.6 in the corners i don't think it would be field relevant when shooting wildlife. As for SR, well i don't think many would handhold such a lens for regular usage, i would certainly prefer to use a solid tripod to get the most out of my 7000$.

With my sigma 500, the pentax shake reduction on the k5 does an excellent job. Only just got a tripod after a 18 months.

They already have a mark for lenses that cover 135format and are made for digital, there are already 3 lenses out actually with that mark
DFA

actually more if you count 645 format as well.


I'm very curious what this lens can do!

I think it might be a crappy brick layer. Should find a better brick wall next time LOL

Yeah, but D-FA implies it has an aperture ring. D* would be a new line perhaps? Or maybe DF/DF* (DF 35/2.4, DF* 200/2.8)
