The D600 is pretty much a game changer woth regards to any future ff launch by any camera manufacturer.
By the time Pentax launch their ff the d600 will most likely be down to around £1100ish how Pentax can compete against that I am not sure, but not only is price an issue so are features. A dual slot must niw be considered an essential, processor is going to be vastly improved over the k-5 mkii.
I can imagine Pentax launching a FF without AA filter around £1400 to compete just tomtry to be different.

Joking aside, it wouldn't surprise me if a FF Pentax came out before long, but at the moment it seems that all we are hearing is thinking and speculation.

It seems to me that there's something of a convergence of technology going on. Image quality with smaller sensors is improving (24Mp without noise penalties?), giving weight and size advantages for camera and lenses; on the other hand I suspect it won't be long before a 24x36 sensor appears in a body no heavier than the K5's (I think the Nikon D600 isn't far off anyway), though rather longer before the price comes down to the same level.
I hope so. Those dinosaur brontosaurus Nikon D4 sised monsters are way too big for my liking. They remind me of fat macho 4x4 vehicles.Mike-P wrote:

In any case if 35mm film cameras can be nice and compact, why does a FF digital version have to be so bloated in size?

TBH every time this FF thing is mentioned I think 645D

Just a point that stood out for me, (and maybe some might find debatable :wink - wouldn't DOF actually be more difficult to manage on FF? I mean, am I right to think you would have to use smaller apertures to achieve the same DOF, leading to slower shutter speeds / higher iso's / need a tripod etc (ie more difficult) ??The advantages for me are better wide-angle options and better control of depth of field .
I'm thinking of all the landscape books I've seen with shots taken on large format cameras with f32 as the most common setting!

Just stand closer to the subject.
AFAIK the DOF for a given focal length, distance to subject and aperture setting is exactly the same on FF and APS-C.

For landscape, I'd agree.
When I first learned to use a film SLR the rule of thumb (assuming a 50mm lens) seemed to be f/16 or more to give a decent depth of field; in reality with ISO100 print film, or ISO25 or 64 for slides, that either meant a tripod or compromising with a wider aperture. With the DSLRs I'm usually in the f/9-f/11 range without any problem.
If I've got the technicalities right it's basically because a smaller sensor will use a shorter focal length for the same shot - so say 34mm with a 16x24 sensor v. 50mm with 35mm FF/film.
On the other hand if you want a small DoF e.g. for portraits then a larger sensor makes sense (pardon the pun!).

It is the pesky circle of confusion parameter which makes the difference between the apparent DOF on FF vs APS-C. This is is a measure of a 'largest blur spot that is indistinguishable from a point'. Often taken as 0.019 mm on Pentax APS-C and 0.029 mm on a FF. DOF is inversely proportional to the circle of confusion size, resulting is a greater apparent DOF from a APS-C sensor as compared to a FF sensor with the same lens and settings.

I meant better control of DoF rather than maximising it, so the ability to reduce it if you want to. If you can stand closer to the subject, then a 50mm at f/1.4 on APS-C might give you similar framing & DoF to an 85mm at f/1.4 on FF, but you might not be able to stand closer.
Obviously if you want to maximise DoF you may need smaller apertures/longer exposures/faster ISOs/brighter lighting, it just means you have to balance these against the image you're looking for.

AA filter-less cameras will be the norm just as the new D7100 is without one. It's US launch price is 100 pounds lower than the K5 IIs UK price now. WR mag body and blah blah blah etc.The D600 is pretty much a game changer woth regards to any future ff launch by any camera manufacturer.

And that reflects just how quickly the market changes, i was looking at the d7100 spec this morning and it looks like Nikon have seen the new k-5 as a threat and copied some of the ideas like filterless AA and fully sealed body.

I was thinking the same thing. Although ref the person above's comment on cost of the D7100 at launch, I am not sure you can compare US to UK, too many variables such as tax, market pricing etc, this early. Also K5ii may well drop more.And that reflects just how quickly the market changes, i was looking at the d7100 spec this morning and it looks like Nikon have seen the new k-5 as a threat and copied some of the ideas like filterless AA and fully sealed body.
I'll be very interested to see how they go without the AA filter.
