Ha ha ha, yes, I guess it
is me you speak of
Quote: Hmm, do you really think next generation APS-C will be close to the sensor Nikon is using in their D3S? That camera has usable ISO51,200. That is mind boggling.
FF will always have a 1.5 stop advantage in noise, that's just simple Physics, so I don't think the next generation APS-C will rival FF sensors. However, I do think that new technologies (like back-illuminated sensors) will make APS-C sensors at least as good as today's D3s. When an APS-C sensor is good enough to shoot at ISO 51,200 with good IQ, will we want to pay $2,000 more for a FF? I shoot at high ISO
A LOT, and from what I've seen, the K-x sensor is nearly as sensitive as I'd need; 1 more stop of improvement and I'd probably not buy another camera for many, many years.
Quote: But high ISO aside, the two features that matter the most to me personally are large view finder and DOF control. Pentax is going to need to make an APS-C viewfinder with at least 1.2x magnification to compete with the worst of full frame viewfinders, let alone something like the Sony A900 has. Plus, some of us still shoot film, it would be nice for 50mm's to = 50mm's on both bodies.
I have not looked through a Canon's FF VF, but I've looked through a D700 a number of times (and the 5D's VF is similar): It's disappointing. Comparing side by side with my K10D, there was little difference between the VFs. I had initially also wanted a FF camera for the VF until I actually used one (I have a lot of manual focus lenses). These are not manual-focus film SLR VFs in these cameras!. Take a look at this
VF size chart, compare the D700 to the K20D. Even the Sony A900, reputedly one of the best DSLR VFs, isn't that much larger than the K20D. Now compare the FF DSLR VFs to the Olympus OM-1. For further comparison, the OM-1 had 0.92 (magnification) x 93% (coverage), while the Pentax MX had 0.97 x 95%, so it would be even larger on that chart.
If Pentax puts out a FF camera, they better give it something like the MX VF, because otherwise there'll be no point in buying it if you want better manual focusing. It's cheaper to just get a 1.2x diopter for $20, which is what I've done on my K10D. Incidentally, it'll be very expensive to achieve an MX-like VF, so I would fully expect Pentax's FF DSLR to be something like 0.70 x 95% (similar to a D700 or 5D).
Quote: Edit: I would like to add if Pentax puts a 1.2x view finder on the K-8 then I would be really happy with it probably buy one. So that is fine for now, but I do worry about the future when the cost difference between APS-C and FF is negligible. Once the price gap drops to $500 or so I wonder how many non-telephoto enthusiast will still buy D300's, K-7's, or Canon 7D's.
I agree with the 1.2x VF on the K-8. I would add my own 1.2x diopter and probably be quite happy with manual focusing (after swapping out the focus screen). But I don't think we'll reach a $500 price gap for equally spec'd cameras. If there were a FF at $1,800 vs the K-8 at $1,300, then the FF would have much lower fps, smaller buffer, probably no video, possibly lower sync speed, and a few other concessions. For some people this wouldn't matter because they just
have to have FF, but for others it would.
Quote: Take a look at the Pentax MZ-S. That was Pentax's last high quality film camera, and it's smaller than a K-7. Canon and Nikon both make cameras large because they think they should. Their APS-C pro-grade cameras are just as large as their full frame cameras. Pentax has a different philosophy. They should be able to make one no larger than the K-7. As far as lens size goes, you won't notice a real size advantage there either until you get up over 135mm's. Fortunately for me I never go above that.
DSLRs are larger than film camera because there is a lot of extra stuff that needs to go inside the body, and a FF DSLR has a larger shutter and shutter mechanism than an APS-C one (and larger sensor, of course). If Pentax could fit a FF sensor inside a K-7 body, that would be great as far as I'm concerned...but you know there are plenty of people who think the K-7 is too small and the K10/20D are the perfect size. You can't please everyone!
As far as lens size is concerned, yes, a 50mm f/1.4 will always be more or less the same size, but what I meant was that a 50mm f/1.4 on APS-C will be smaller than a 75mm f/1.4 on FF (and both give the same FoV). This doesn't quite work for very wide angle lenses, but it does for my most used focal lengths (I'm not really a wide guy). Yes, the benefit here is mostly to longer FL shooters. People who like wide angle need not read this paragraph!
Art, I'm not against Pentax giving us a FF camera, but I don't want them to do it if they're going to half-ass it and further sacrifice advances to their APS-C line. As someone who likes the advantages of APS-C, I don't want to be left with no options. Pentax cannot put out a K-8 for $1,300, and also a FF for $2,000, because very few people will buy the FF. The K-7 is already a great APS-C camera, if they tweak it and add a K-x level sensor in the K-8, we'll have an extraordinary camera at a great price. What will we get for $700 more? A few extra pixels and 1.5 stops in high ISO performance (and less FPS and whatever else they've cut down to meet the $2,000 price tag).
In order to sell FF cameras in significant enough numbers to recover investment costs, Pentax would have to make their $2,000 FF really attractive, and you do that by making the next camera down not look quite so good. So maybe you cut out the high level APS-C camera from your range and just have a beginners model (K-x level), an intermediate model (a K300D) and make your FF the top of the line which all the bells and whistles previously found on the K-7. The problem is that adding bells and whistles to a FF (as in fast FPS) is going to be difficult (if not impossible) if they're selling them at $2,000. But if they price them so they don't lose money (say $2,500-3,000) then they won't sell any. Classic Catch 22.
So maybe Pentax need to have a high performance APS-C and a lower-performance FF in the line up at the same time after all. But then we're back to why people would buy a lower performing, more expensive camera simply because it's FF.
I just don't see the numbers adding up right now. Maybe in 2-4 years time FF sensors will be cheap enough that it all computes, but right now I don't see it.
It's not that I don't want you or the other guys to be deprived of a FF camera, Art; it's that I don't want a FF to become the albatross around Pentax's neck.
