How ca you tell?

How can you tell, if a lense can cover the FF format sensor, or just APS-C?

Perso, I plan to borrow an A7 + K mount adapter to evaluate the FF capability of all Pentax lenses I own.
The advantage of knowing in advance, is to be able to sell APS-C lenses before the price drop when the Pentax full frame will be released and people selling off their APS-C gear to finance the new full frame camera.

I am not selling mine even if it is for APS-C only.... my k-3 will still be my work horse...

I haven't found a compelling reason yet to buy FF. Don't get me wrong, I think it's great that Pentax is building it and I hope that it's wildly successful but for my purposes my lowly K-50 and my K-5 IIs are more than sufficient to cover my needs now and for a long time to come.

As I recall from one of the interviews recently posted with RIcoh staff, Ricoh will be evaluating the existing lens line as to which are full frame capable. At the very least this information will be made available even perhaps rebadging some of the lenses still in production as FA or some other designation. Whether these evaluations will extend to DA lenses no longer in production remains to be seen.

Just a guess, but I bet the F's, FA's and earlier will cover FF.

For those of us who use telephotos a lot for sports and wildlife, there are advantages to the current APS-C sensors and for that reason, I'll be keeping a camera that uses them. I'm not saying I will never own a FF and I can see good reasons for having one of each camera bodies.

Very true ! Most of us will benefit not much at all from FF even though I must have it too.
Can make huge prints already from the K30's and K3 so other than a "Must Have" there isn't even a good reason why I "need" it.
Just wait til it comes out....there will be a lot of whining and unhappiness about edge sharpness on certain lenses compared to APS-C.
I can just see it now. Well....my XYZ lens was great on my old camera that worked stellar before.....I can just see it now a couple years down the road.....lol.

I think it's pretty much assumed that those who will buy the FF camera will have a pretty good working knowledge of photography and know what to expect. That said, there are a lot of people who never shot 35mm film, have never looked through a 35mm viewfinder, and only spout off the BS they have read in various articles and forums. Some of them are going to buy the FF for no other reason than it will be the "flagship" camera body and are likely going to be disappointed.
