At that power, you really get into atmospherics anomalies, plus lens design flaws that show up when you are only using the very center of the field of view of a given 35mm lens.

There are some things for which APS-C isn't good enough: spreads in Vogue, billboards, and impressing the easily impressed.

From: J.C. O'Connell Seriously, what is the latest rumours about FF Pentax dslr? The latest seems to be the officially deemed FAKE mid-March 2013 rumor that Pentax would announce the K-3 using Sony's 24mp full-frame sensor. Instead we got 9 bold new colors for the K-30 (which BTW was no longer on display at Tiger Direct during my weekly music/computer store pilgrimage last week).

Re: Pentax FF DSLR is vaporware?
P.J. is right, at least in my case. If/when Pentax introduces a full frame DSLR, I will probably buy one (eventually) but I won't be one of the first in line. A full frame sensor, by itself doesn't really gain you anything except: 1) shallower DOF (at the same focal length, compared to a APS-C) 2) losing the crop factor (meaning your 15mm is a 15mm FOV instead of a 22mm FOV) - helpful at the wide angle end and for tilt-shift lens users. 3) more megapixels (potentially significant depending upon the pixel pitch) 4) if a larger pixel pitch, then potentially better noise performance at equivalent ISOs The downsides: It depends upon what sort of shooting you do, but a larger filesize is probably going to mean lower frames per second on burst performance for action shooting, compared to a APS-C camera. Fewer frames until your buffer is full and has to wait to take another shot. Larger filesizes means more computing power to post-process and store images (something we seem willing to live with). Macro shooters will find thinner DOF to be a disadvantage, rather than an advantage Full frame DSLRs will really show the deficiencies in your lenses, particularly in the corners. That said, Pentax probably needs to produce a full frame DSLR, just to show they belong with the big boys and prevent some (more) from jumping ship to another brand. For my part, I love wide angle but find that the Sigma EX 10-20mm more than meets my needs on the wide angle end of the spectrum on a APS-C camera. I also love macro, so the increased DOF is a plus on an APS-C. The K-5/K-5 II already leads the pack at high ISO performance and the megapixels already exceeds what I need for the print sizes I will realistically ever print. I can get shallow DOF with my Sigma EX 28mm f1.8, my CZJ 35mm f2.4, and my 85mm f1.5s (heck, the DOF is shallow enough in many cases on my Bigma - why would I want to make it more challenging?) In short, the Pentax flagship cameras meet or exceed my expectations right now and a full frame doesn't do a lot for me other than let me proclaim that I have a full frame camera.

I should also mention another significant negative... when you lose the crop factor you lose at the telephoto end.

Re: Pentax FF DSLR is vaporware?
I disagree with one point made below. FF actually allows LOWER quality lenses to be used because the absolute lines/mm doesnt have to be as high for same quality of results. Yes with some really bad lenses the softness in the corners may become more visible, but with decent lenses, FF puts less emphisis on lens quality than apsc does. -- J.C.

I also love macro, so the increased DOF is a plus on an APS-C. The K-5/K-5 II already leads the pack at high ISO performance and the megapixels already exceeds what I need for the print sizes I will realistically ever print. I can get shallow DOF with my Sigma EX 28mm f1.8, my CZJ 35mm f2.4, and my 85mm f1.5s (heck, the DOF is shallow enough in many cases on my Bigma - why would I want to make it more challenging?) In short, the Pentax flagship cameras meet or exceed my expectations right now and a full frame doesn't do a lot for me other than let me proclaim that I have a full frame camera.

Its similar to large format film vs smaller format film. The larger the format, the less critical the lens becomes because the absolute resolution of the lens times the area covered is still more than a small format area used with a high resolution lens. -- J.C.

That's pretty much what Ken Rockwell says: You Can Use Cheap Lenses! I get better results on full-frame with crummy lenses than I do with my very best lenses on DX. Having bigger pixels on a larger format means you can use cheaper lenses and usually get better results than the best lenses on a smaller format. The only reason I use the weasel word of usually is because as of 2007 we're only talking about a 1.6x linear format difference among consumer (under $9,000) DSLRs. In film, with a 2x linear difference from one format to the next, the crappiest lens on the next bigger format always smokes the very best lens on the next smaller format. -- Larry Colen l...@red4est.com http://red4est.com/lrc -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Very well said, Darren. I totally agree... Now, not answering you directly, but rather to a topic question: In fact, for me Pentax DSLRs such as K-5 exceed my expectations and abilities in such a manner that by now I shoot exclusively with Ricoh GXR-M module with or without K-mount adapter. I should say that A 50/1.2 is one fine lens on that camera body and it is not as big or heavy... Additionally, Nokton 40/1.4 is even so much smaller and lighter making Ricoh GXR-M with it pretty much a perfect camera for me - in terms of size, ergonomics vs price, convenience vs picture quality that I am able to get from it. In the past I was rather strong proponent of (Pentax) FF, but I have changed my mind. I don't think that I need the added bulk of FF camera (it ain't gonna be small, at least by now) and added bulk of RAW files from it - 24 MP RAW files aren't small... I may benefit some things such as AOV or DOF, but it is far less critical that I thought it might be...

What this means in real world terms is that you dont need super world class lenses on FF to get great results, unlike with APCS sized sensors. JC, consider this: 36 MP of Nikon D800 is more than twice the 16 MP of Pentax K-5 or Nikon D7000. Therefore your FF Nikkors ought to be as good as they are on your APS-C D7000 in terms of spatial resolution. Consider further, that it stands to reason that the next generation of FF sensors will have even more pixels in them. I vaguely (sorry :-( ) recall rumors of next Canon FF DSLR flagship having in excess of 40 MP. Therefore on FF your lenses actually have to be even better in this regard than they were on current APS-C cameras. So in theory you're right, but it would seem to me that technology would soon enough overtake your theory, in a manner of speaking.
