I was under the impression that the DA*55 was FF fully compatible, but according to DP review reports that it's useable stopped down. Not sure to what extent it needs to be stopped down. Anyone know if there are examples of this lens on a FF camera and an example of it having to be stopped down?
Ricoh has prepared lens aberration correction in the full frame only for the 200, 300 and 560. All the rest of the DA lenses are listed in the crop lenses table. That doesn't mean DA*55 isn't fully compatible - just that Ricoh hasn't installed lens correction in the FF mode.

See page 4 (of 6) of the new Product Information HERE

Ken, would you mind checking and explaining four items in the K-1 camera configuration, please:

a) What exactly does the "flash sync speed" config do and which options are there?

b) what exactly can be configured around the "electronic shutter" in live view.

c) What does "Certification marks" do?

d) what is meant by "Change AF point button"?

Prior models didn't have either and since we don't have a manual, it's an unknown. But you should be able to find out.

Mac mini:no one is powerfull enough.
Sorry, only caught some paragraphs. You are talking about working out 36mp raws?
I'm using a Mac Mini late 2012 Intel Quad Core i7 2.3GHz, 16GB RAM, fusion drive ... with Capture One. Never had a problem in editing any raw or big tiff image file up to 100MB. So, easily powerful enough for the task to work out the K-1s raw files IMO. But maybe I didn't get your point.

No offence but my point was not to say the Mac Mini is not powerfull enough to post process 36MP image but to match the deskop configuration I provided earlier in that post.

This was in response that mac are not more expensive for the same gear and resell better so I took a basic desktop config: 4 core i5 3.4Ghz, 16GB RAM, 1TB HDD and check what Mac matched that and for what price. The mac mini wasn't able to match it. This doesn't mean you could not process high resolution image with it.

A 720€ desktop you would have brought 3 years ago sitll have the same price today and would resell a bit under that like any used gear. He didn't loose value. It also provide the same performance between the 1700 and 2200€ iMac. Even if we add a good screen to the computer (something that you don't need to buy each time you upgrade/change computer) for 300€, that still half the price.

Mac have the design/look, nice intuitive software and so on. They are not king of provide the most bang for the buck and that not by any mean a problem, there both Ford and BMW in cars. Why not computers?

Thanks for clarification! - Mac OSX vs. PC/Windows is another story ...

Well, the K-1 certainly has a lot of appeal.

Right now, I have a K-3 with 7 lenses, only two of which are FF compatible (SMC FA 50mm 1.4 and SMC-D FA 100mm 2.8 Macro). I understand that my SMC-DA 35mm 2.8 Macro Ltd. will also work stopped down (how the hell does that make a difference and how far stopped down?).

My understanding is that the K-1 in APS-C cropped mode will provide a 15mp image. I'd like to see side by side comparisons with any given APS-C-only lens of pictures taken with:

K-1 in cropped mode (15 mp)
K5 (16 mp)
K3 (24 mp)

I suspect that for sure, the K3 will prove superior with an APS-C lens, and that the K5 might be equivalent to the K1, with the built-in moire filter of the K5 casting some doubt on sharpness.

In short, with my APS-C lenses, I might be better off taking pics with my K-3 than the K-1 in cropped mode. Am I wrong? I have an investment in APS-C lenses, and I would want to use them to the best possible advantage.

Regardless, I'm happy with my de-bugged K-3 now; I think I'll wait to let others work out the inevitable bugs on the K-1 and let the price drop on it before I take the plunge.

That's one of the best possible buys from the used market. Because Apple doesn't sell quad core minis anymore

Not to be a wet blanket, but we all know it is "shipping in April." so perhaps another 50~60 days before any of us get delivery.

Was it really necessary to complain about this in multiple threads?

You're right, we did know this already. Ricoh was completely upfront about it at the time of the official announcement. We are allowed to be happy anyway.

There is also the possibility of simply going manual crop with the K-1 - using your APS-C lenses in FF mode, seeing what works (or not) and what aperture or focal length gives you results you are happy with, and then manually cropping the 36MP image to suit (if needed).

Some DA zooms may need this sort of approach more than primes, as they may (for arguments sake) vignette very heavily at wide zoom, but work fine at normal or longer zoom, and so produce fine 36MP images at those longer focal lengths. If you relied on the camera to just apply auto-crop to such a DA zoom, all you would ever get is 15MP images, and miss the chance for lots of problem-free 36MP images.

Unless, of course, the Pentax 'Auto' crop function is smart enough to selectively crop a DA zoom lens only to the focal lengths where it is needed - eg for the DA 17-70, 17mm = apply crop, 30mm= apply light crop, 50mm and above = do not apply crop. I doubt this will be the case, however.

So IMHO just shooting 36MP all the time, and manually cropping, may in general be the best way to go, particularly with DA zooms. (And for non-Pentax crop lenses the camera may not have in it's database].

c) What does "Certification marks" do?
Probably displays regulatory conformance marks like CE, FCC, UL, etc. Some Android devices have a similar option, in Settings > About [phone/tablet] > Regulatory information.

On the youtube review (posted on the front page of PF here) the guy said he saw no vignetting on his copy.. it should be a solid lens on the K-1.
