Surely on full frame the edge distortions will be more apparent than on APS-C where you will be only seeing the image from the best parts of the glass? The graphical depictions of the lens distortions on the lenstip.com article show a marked increase in the distorions at the very edges right the way around, and a smoother gradation in the centre. On APS-C I don't think you'll be viewing these outer parts of the image.
I think that's right, and that's exactly what Photozone.de says too.Surely on full frame the edge distortions will be more apparent than on APS-C where you will be only seeing the image from the best parts of the glass?

Ultra wide angle lenses often struggle to tame the amount of barrel distortion and this is also a major weakness of the Samyang 14mm f/2.8. It produces a whopping 5% barrel distortion. For serious architecture photography this is pretty much a no-go unless you correct the problem during post-processing. The barrel distortion isn't quite as complex as on full format DSLRs fortunately.

Not sure about that Mike. The 85/1.4 is usable at f1.4, but the focussing issues with such wafer thin DOF go with the territory. Liveview and now focus peaking can help a lot.
The 14mm does have some barrel distortion (especially on FF) but the sharpness - according to every review I have read, and every sample picture I have seen - is great right from f2.8. Nice set of images shot on Pentax here: http://stefanlc.blogspot.co.uk/2011/10/blog-post.html
I haven't actually seen a bad review of a Samyang lens tbh.

The judge has not specified it needs to be in the UK, just the 'everyday environment' (so pretty much anywhere I guess!)

Also the D600 is fairly compact for FF standards but the lenses are just as massive and heavy as for the rest of the FF. So as far as FF is concerned even a K-5 sized/weighing camera is not going to make much of a dent if you still have to carry FF glass.
Of course on the other hand a K-3+FAltds is unmatched for size/weight compared to Canon/Nikon exactly like the K-5+DAltds is.
There are people out there who thought nothing of buying the X-pro 1, with it's three lenses, the minute it was released. The set up had a wallet-sucking sense of exclusivity and quality about it. The FAltds are what non-Pentax users tend to talk about whenever they are being remotely positive about Pentax. They are desirable. If Pentax were to release a 'unique' FF camera, they would surely wish to capitalise on that. Some people have deep pockets and just can't be without new 'shiny things'....

Is this really what so many folks are alleged to want? Light and compact (and, er, not £15,000) is the way to go, imho. Pentax have always been very savvy about this, but I don't know how easy it is to keep it compact on FF. Going larger and more expensive is a very odd thing to do when the rest of the world is going for smaller, lighter, nimbler and often cheaper too - mobiles, laptops, etc.
I think mirrorless camera systems are gnawing at APSC DSLR sales at one end, and FF cameras are sucking away consumers who have already upgraded to the top APSC model at the other. I think a lot of people want those smaller, lighter cheaper devices but many, onced sucked in to 'enthusiast' photography, they start upgrading. If you already have a Sony NEX or something like that, a K5 vs a 5D mkIII both look big cameras, yet the latter offers a more decisive image quality improvement.

Even if this hypothetical NEX user doesn't jump straight to a full frame camera, going to Canikon would make sense if there's aspiration of doing that a few years down the line. Pentax may be ruled out because this is something they do not currently offer.
Furthermore, Pentax has to encourage existing users to upgrade, and perhaps to part with a bit more cash when they do so. Offering a FF option might encourage more K5 users to upgrade, because it's hard to imagine an APSC camera much better than the K5 (in IQ terms at least).

A FF would offer more compact *fast* wide angle lenses though, at least Algi. I adore the DA15mm (equivalent FL = 24mm), but would love a compact 24mm f2.8. The FAltd trio are also pretty compact, and fast - and would reveal their true character in depth of field and FOV on FF.

On the subject of price, if $2800 is fairly accurate, that equates to about £1875-£1900 body only, although the UK price often ends up closer to the dollar equivalent.
I would say that they need to bring it in at below £2000, particularly if it uses the same sensor that will have had a 6 months headstart on a Sony camera. Can't really understand why it seems to be taking so long to appear.
I am very interested to see what they come up with, but I wouldn't be surprised given recent past record, if they didn't attempt to compete with Ca/Nikon directly on price (the D600 will make that difficult now!) and concentrated on the niche of photographers who want a really high-end, compact-sized kit (including the FA ltds which are ready to go with this camera).On the subject of price, if $2800 is fairly accurate, that equates to about £1875-£1900 body only, although the UK price often ends up closer to the dollar equivalent.

On the other hand, Ricoh did say they wanted to compete with the big two, so who knows!

Interesting alternative to the Yongnuos, Minolta 4000AF: http://www.pentaxforums.com/accessoryreviews/showproduct.php?product=1118&ca...
I just bought one for £1.20, plus £3.00 delivery! It seems pretty good so I got another from Rocky Cameras. Rather huge compared to modern flashes though, no 2nd curtain sync, but the power settings are there

No, there's a mash up of the April Fools Day K3 picture and specs (quoted as 'previous rumours have included...') and the recent rumours from DC Home via RiceHigh's blog:This was the camera 'announced' on the 01/04/2012 - there have not been any changes to the specification or the picture since then!

What are mentioned:-
1. Pentax will make the world's most compact Full Frame body which is to be marketed by March 2013;
2. Two body colours, in black and in silver;
3. Using the new Sony 24MP FF sensor, possibly the same one in the upcoming Nikon D600 and Sony A99. However, owing to the agreement between Sony and Pentax, the new Pentax FF has to be put onto the market six months later;
4. A new FF kit zoom lens starting from 28mm wide angle;
5. Together with a new vertical battery grip;
6. And also a new flashgun unit, too!
7. To be sold at HK$22,000 for the body only (equals to US$2820);
8. Will be announced "soon" in September (at Photokina?).
Nothing has been mentioned about the video, though. But are the above already exciting enough? Real or not.

I think that the program A has no Tv mode, so no control of DA lenses. Super-A or Super-Program is the one with TV mode. Confusing eh?
