Officially K-3?
Just reading around the internet and noticed a couple of things, one from DPreview and one on Steve Huff: DPreview have a preview of the K3 and they love it. There only critism was despite all the extra AF points, the AF barely performed any better than the K5 II. And on Steve Huff, someone me...

Officially K-3?
[quote:3496ace15f="George Lazarette"]If I banged my head, and woke up to find I "needed" more pixels, then I would do what to me seems the obvious solution, and that is to acquire a 645D. I would then have a choice of formats at my disposal, with all the ergonomic advantages of the K-mount on the on...

The Pros use FF - therefore if we had one - we would be pros in a few years time, FF will dominate the market and APS-C sales will wither. Andrew Be careful what you predict - Vinyl record sales are up 745% vs.2008 :D Will APS-C wither? bound to eventually. Will FF dominate? - possibly, po...

I'm looking forward to seeing all the brilliant FF pictures that couldn't be taken on APS-C :roll: Appreciably shallower DOF than possible on APSC. http://farm6.staticflickr.com/5533/9064453333_ce53e3fbbc_b.jpg http://farm6.staticflickr.com/5519/9212742327_026e0efaa5_b.jpg http://farm4.sta...

On what evidence are you basing this ridiculous comment on? On reading numerous forum comments where people say they have bought a crop sensor camera but intend to get a FF when finances allow... and are already amassing FF compatible lenses. Heck some people on THIS forum are already marketing the...

IOW the sensor size does not change DOF. Changing subject distance changes DOF.

I have to say that I'm astonished by the quality of this image, from the K3 sample image gallery: http://www.ricoh-imaging.co.jp/english/products/k-3/ex/img/ex-pic01.jpg Had I not known where it came from, I would have assumed that a FF sensor camera had been used, or even medium format.

IOW the sensor size does not change DOF. no it doesn't, but changing focal length does and a larger sensor size dictates a longer focal length for the same subject distance and framing. You know this perfectly well.

Its not just about the cameras either - you need to re-consider your whole lens line-up. For us Pentax people its no small thing to have to offload a collection of DA lenses, for .... what exactly? Its a bit of a mish mash of options and independants isn't it? There's not really a clear 'road-map' o...

Actually sensor size does change DOF in the sense that if the sensor is smaller then the diameter of the acceptable 'circle of confusion' must also be correspondingly smaller. This in fact reduces DOF for smaller sensor cameras. However for a given angle of view the decreased focal length required b...

I was just saying that there's a clear road-map for 'Crop' lenses, but the options for any future bigger sensor models are less clear. Of course, there are loads of suitable lenses to put onto a FF camera, but they're a 'mish-mash' of legacy 35mm glass, a small number of current premium primes if I'...

By the same token you could argue that some people with DSLRs should downgrade to a point and shoot. I've know several where this would probably be a good move! I'm sure FF will be better for some shots than APSC, but for most users I doubt it would be noticable. Quite oftem for macro a SMALLER s...

FULL FRAME....invented by Oskar Barnack before the 1914-18 World War in the LAST CENTURY, simply because it used the cheapest available film, 35mm cine film which could take a double frame 36x24mm image if used on its side instead of vertically in cine cameras. Great for film, which is still bein...

I know that generally a larger negative/sensor/transparency can lead to a better quality image, mainly because it doesn't have to be enlarged as much, but there is no special magic in "full format" 36x24. That's right. There was no rush to go from 36x24 to 24x18 using the same film stocks because th...

Interesting Reading about simulated AA filter of K-3
I totally agree that its a clever thing, and I fully understand what its doing, but why anyone would want their sensor moving during a shot just baffles Me!

What will be really interesting to find out is whether having it 'on' will add to blur, in the manner of an actual aa filter. If the sensor is moving it will add to blur. It might be slight but it will be there; if it didn't do this it wouldn't prevent moire. Regards David
