I'm really looking forward to another 100 page thread with plenty of rants.

Round 4000, fight!

But it's quite demanding on lenses. Are we sure any of the very few existing FF Pentax lenses actually on sale have enough QI for that sensor?
Well, the best of the M42 lenses (85 1.8, 50 4, 105 2.8 etc.) out-resolve the 16M pixel APS sensors, a full frame with 32 M pixels would have the same pixel size and would still be perfect (at least in the center), I have a feeling some of the FA's could keep up.

Not sure if this has been posted yet, but here's another blog that mentions the new FF.

This is pretty set in stone, no?

If you count compacts, yes; but for real cameras, I doubt Samsung is even close (do they even have a real camera? ).
Well, for a while Samsung was rebadging Pentax cameras. Not sure whether that refutes or reinforces the not a "real camera" company claim. I have no way of knowing but I sort of doubt the relationship will be rekindled, at least in terms of bodies and lenses. With sensors I imagine it could be reignited under the right circumstances. I like the slimness of the NX line but am not tempted to spend money on one.

I can't believe this keeps getting recirculated! It was an April Fool's prank. Pentax K-3 Announced - Pentax Camera News & Rumors - PentaxForums.com Sorry if I misunderstood your post and you already knew this.

Yes its another blog on the topic, but if you follow their sources it all leads back to the same spot. Although with each report there are new bits of information added. It's all like a big game of Chinese whispers.

Edit: And yes Tom is right, Most of the specs/images are courtesy of our admin's humor :P

To me a full frame means losing focal length, being that i can't afford a 500 or 600mm F4 lens for 10-20 thousand, i like that my aps-c gets me there with a 300 and 1.4 teleconverter (which please pentax get us an autofocus compatible 1.4 soon) now that would get me excited.

You lose nothing of the sort. Focal length is independent of sensor size.
You GAIN angle of view, but the central crop is exactly the same image you would have had with APS-C.

What you're regaining with FF coming from APS-C is the originally intended, and naturally wider, AOV of FF lenses. Something I very much desire, especially at the wider angles and with faster lenses. My FA 31 Ltd won't stop begging to be put on a FF body, film if necessary. With the high MP FF sensors coming out, and likely to be put in any Pentax FF camera, you'll still be able to crop and enlarge like crazy anyway so no real loss, IMO.

EDIT: Didn't realize Sandy had already made this same point. So yeah, anyway, dido.

What we'll get with a FF Pentax:

* wider AOV than APS-C; but a 24mpx 32mpx FF image cropped to APS size will be the same as a 16mpx APS image, all else being equal
* thinner DOF when adjusting distance for VF-filling; but if both the 24mpx 32mpx FF and 16mpx APS shots are taken from the same plaace, DOF and perspective are identical
* no end to the rumors of new FF cams; there's alway room for another rumor; pretty soon we'll be frothing over a telepathic 645-FF MILC

EDIT: corrected

Rumors are worse than vampires. Once staked through the heart, vamps die. But rumor arise again and again to haunt us forever, or at least until the next hot rumor. Hay, have you heard about the new Pentax Medical corporate proctoscope that mounts on the nose?

That's what I would figure but I keep reading people state that the new 36 MP D800 sensor is a scaled up version of the K-5 sensor and that it has the same pixel density of the 16 MP K-5 sensor. A FF sensor has 1.5 times more area than the current standard APS-C sensor. So if you take the K-5's 16 MPs and multiply it by 1.5 you get 24 MP. And, if you take the D800 and divide it by 1.5 you get 24 MP. So, it seems to me that the D800 has the same pixel density of the new 24 MP D3200, not the 16 MP K-5 or D7000. On those same lines, the rumored FF 24 MP D600 would have the same pixel density of the K-5 or D7000. Are the statements going around that the D800 has the same pixel density of the K-5 wrong, or am I missing something?

To me FF means using my FA Limiteds the way they were meant to be used... and thats reason enough for me to go FF

FF is ~1.5x the linear dimensions of APS-C. That is 1.5 x Height and 1.5 x Width.

Area = 1.5 x 1.5 = 2.25x APS-C

2.25 x 16 = 36

I corrected my earlier mistake. The 1.5x factor is on the DIAGONAL, not the height|width. So an APS-C 16mpx sensor with the same pixel density scaled-up to FF would be 32mpx. APS-C is very close to 135/HF (half-frame) or 24x18mm, half the area of 135/FF at 36x24mm.
