do i need an upgrade from the K30?
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 ...

K3 settings
My k3 is finally in and I'm going through the settings. Just to clarify my understanding: When shooting in raw none of the camera 'processing' settings apply, such as high iso noise reduction and lens corrections? So I can just turn them all off? The only 2 I can think that do apply are the...

Optimum settings for K3
Hi Paul, optimum settings? Could you expand a little are you talking about specifics in relation to ISO, Aperture, White balance, Shutter Speeds etc, or is your question purely about JPEG settings? I guess it really depends on what you are photographing, the lenses you use and the lighting condit...

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 Does not fare well in DXO tests...
I'm not sure what it all means in the real world. My friend's Canon 700D never seems to have much noise in blue skies. My K30 was pretty good but my K3 doesn't seem to like blue skies much. This is a 100% crop, raw unaltered no NR, ISO 200. Comments? - would the high 1/3200 have an effect? Not re...

Jules that also means in 5 years Pentax hasn't got close either :? ? Pentax DSLR's are among the best out there, imho THE best but it's not just about image noise, if you increase the DR output you get more noise, if you take out the AA filter you get more noise, if you increase the colour depth,...

I agree with just about all of that except that the removal of the AA filter won't increase noise. If anything it would let more light through and less sharpening would be required, both of which could slightly reduce visible noise.

"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...

Custom image settings
I'm a jpeg shooter too and I use the default bright with EXS plus one for sharpness. I originally found the three sets of sharpness level confusing but happy with it now. Post capture I tend to adjust brightness, contrast and sometimes clarlty as this seems to pop good images presumably to overco...

Exposure settings with ND Filters
I have a K5 and I have recently been experimenting with using a Hitech 0.9 ND filter on a Pentax 17-70 lens. Without the filter and using Manual exposure set to 0, the results are as expected and the exposure is correct. If I then use the 0.9 ND, I re-set the Manual exposure to 0. However, the...

Exposure settings with ND Filters
Have you pressed the green button after fitting the filter? This will reset the meter, and yes, in theory the brightness should work out being the same as without the filter. It sounds like the EV is remaining at the previous unfiltered settings ... Can you note the exposure settings? If they are n...

Exposure settings with ND Filters
Hi Nigel, the green button carries out a different function to adjusting the exposure adjustment indicator .. The zero indication simply means no adjustment away from the metering systems default reading and exposure value. Moving the indicator is applying user adjustment away from this metered valu...

Great K3 review
So, K5 IIs and K-3 each have different qualities and each is better than the other in certain respects. It is becoming seriously hard to choose between K-5II, K5-IIs and K-3. Seriously hard! I think the choice you have is more realistically between the K5IIs and the K3; there's not much point in...

Infra Red Conversion
Does anyone know where I could get either a K10D or Samsung GX20 converted for infra red use? I played around with infra red film in the past and I have also tried using my K5 with an infra red filter, with limited success but I'd really like to get one of my older camera bodies converted for perma...

K-S1 Wins The Camera Store TV worst camera of the year
Isn't this though a repeat of the K-01 story, where some could not accept the new design but now it's quite sought after? I think a lot of the demand comes from the fact used ones are usually sold for around thee £120 mark which is a bargain when you consider it cost over £600 new a couple of years ...
