Using sensor shift
that's rather nifty

do i need an upgrade from the K30?
I have no doubt that one of the higher spec models will have things to offer you ... Eventually! But it takes time to explore and discover those features and to learn how they might in practice be a benefit. You don't have that time before your trip, so stick to the camera you know and work at getti...

Quite a few differences ... although they both have strong supporters and users who love them! K5iis has 16 megapixels / k3 24mp Both have no aa filter over the sensor, but the K3 adds a new 'aa filter simulator' that uses sensor shake technology to simulate the effect of the aa filter if you ...

The dreaded K30 aperture motor failure strikes again
Update to my underexposure problem on K30. "Underexposing in auto modes, very high ISO selected in bright conditions" had the repair quote back... £245 to fix "Mechanical asembly, Shutter mechanism, mirror asembly and sensor clean" :!::!::!::evil: Yeah right. Is it because I'm out of warranty...

The dreaded K30 aperture motor failure strikes again
very interesting, but, alas, no use to me now as my K30 (bought nov 2012) died a very sudder death at the weekend - right in the middle of the track cycling world championships. the mirror stuck down first of all, i managed to get it to raise by 'pretending' to clean the sensor and it worked fine fo...

K-S1 Love it or hate it but FWIW...
I hear you Jules, in that I see this as the K-500 replacement presently and the K-50 version must surely be on the way. Thing is though, despite the radical new looks and all, I'm scratching my head a bit as to what has really changed underneath. You get an AA filterless camera for presumably no...

K-S1 Love it or hate it but FWIW...
Whilst I would hope that the KS-2 is WR , as I understand it the KS range is going to be developed in parallel with the existing K range and not replace it. The KS range according to some senior executive interviewed recently is aimed at the younger generation impressed by flashing lights, bright co...

K-S1 Does not fare well in DXO tests...
As you mention and I've said before, we really do seem to have plateaued with regards to performance out of an APS-C sensor. Nowadays the supporting features are what will distinguish the models, such as wifi built in, better metering ability (but personally I think that one has actually plateaued ...

"AA-filter" is a misnomer for the birefringent plates that are put before imaging sensors. The AA filters in DSLR cameras have a clear blurring effect when looking at 100% crops, they blur information across pixels, in effect reducing the high-frequency content, including noise. But the Sky noise ...

An AA filter does not reduce noise. The sensor itself generates thermal noise, much the same as any semiconductor, and as we're talking about a light sensitive sensor, it's the noise it generates in the absence of light that is the reference point as that is the worst case for signal to noise ratio...

Expanded ISO
I guess with the native iso for a cropped sensor camera to be around 200. This is wht you are getting results that are easier on the eye. As you are not working the sensor so much.

Possible D800 to K3?
The k-5 mkii is a far superior camera to the d7000 I have owned both and sold the d7000 after just three shoots with it. Whilst the d800 files maybe big are you prepared for the drop in quality from full frame to aps partiularly in low light? Whilst the pentax bodies maybe better than the nikons ...

Great K3 review
Further to post above and to richandfleur's link, I'm not trying to claim the K-3 is anywhere near as good at high ISO as Sony A7, just observing that it's no worse than my K-5iis in my opinion. Regards David No worries David. You have experience with both, so you carry a lot of weight in t...
