K-3 or K-3 II?
Pixelshift and GPS are a better fit for me over the built in flash. Sensor / firmware tweaks add to the II being the more desirable option.

K5iis Mirror partial reflex
Cleaning lens and body mount contacts with a soft dry cloth is another possibility, just in case the contact has been partially lost. Other than that, back to JPS for a repair quote i think. I would suggest joining Pentax User Plus first, then you can download the form from this site for a 20% di...

K5iis Mirror partial reflex
You could try the sensor cleaning mode if that fails it looks like you have a serious problem. My K10 failed a couple of months ago, you can hear the motor straining to lift the mirror in the above mode. John

What do you know...I tried sensor clean and it seems to have cleared it, at least for now. Here's hoping :-))

K20d or k7 any advice
The K7 was the successor to the K20 in 2009, and I understand the following to have been the key new or significantly improved features ... (the K5 retained these improvements and added the new sensor) ... New, faster Prime II Processor Increased memory buffer Faster burst shooting (5.2fps) La...

K20d or k7 any advice
I couldn't agree more with Andrew there ... Getting the images you want is not only about sensor performance. Sometimes, reading these forums when cameras are being compared, it would be easy to assume that the sensor and it's low light performance is the only important thing to worry about. Of cou...

K20d or k7 any advice
we all know the K7 is Nigel's love child:D but the K5 series did give improvements over it with the K5 11s probably being the peak of that series as by then you had improved ISO performance which is not just about being in the dark but just being indoors where sometimes you need to up it without cre...

K20d or k7 any advice
There is also one other point which no one as said and that is the k20 as the Samsung influence where as the k7 as the Ricoh influence there is a big differance there The K7 came out early in 2009 when Pentax was still with Hoya, so not much Ricoh influence probably .... It includes a Samsung senso...

K20d or k7 any advice
Looks as if I set a few hares running with this topic! Thanks for the advice, you'll be pleased to know that i have taken what on board your comments and advice and have decided to go with a secondhand K5 - damn the extra expense. If it is half as good as the K10 I'll be very happy. Will be intere...

What camera?
Carl, Correct me if I am wrong but the Q with a kit zoom lens is still too big for a pocket? And I am worried by the small sensor in terms of the shallow DOF (I know sony RX100 will struggle there too) and the high iso performance. Thanks.

What camera?
The Q with zoom will easily fit in a jacket pocket. The problem with small sensors is too much depth of field rather than too little. It's much more difficult to get any differential focus. High ISO doesn't have to be a problem. You won't get K-5 performance in that respect, but it's not that ...

What camera?
John, This is what I meant. Small sensor will struggle with getting a shallow DoF which I like. Maybe there is someone with Pentax Q in Glasgow that I could meet and try it in real life?

100% view finder
It means that what the sensor sees is exactly the same as what the viewfinder sees. 100% of what is recorded is shown in the viewfinder. The magnification at which it is shown is 95%, which means the picture you see is the same but slightly smaller than real life. However, 95% is actually very go...

In the case of cameras with IBIS and composition adjustment, the OVF sees what the lens sees, NOT what the sensor sees. Here is where slight differences could occur with the recorded image Only an EVF displays what the sensor receives. ► http://snapsort.com/learn/viewfinder/coverage

The OVF crops the circular 'image' to represent the area to be recorded. Surely so does the sensor?

The sensor does nothing but 'sense' the light which falls into it's buckets.

100% view finder
The circular image projected from the lens clearly needs to be a little bigger in total area than the sensor and viewfinder image ... Just because of the differing shapes. But, to repeat John's point, a 100% viewfinder displays the total edge to edge image exactly as the sensor records. The .95x mag...

I think the OP wants to know why the photo is wider than what he's seen in viewfinder, not technical explanations what is 100% viewfinder. Bottom photo got more scene on the left side than top photo. If viewfinder is 100% they should be the same. So is it 100% or not then? We've got two images th...

Why is everyone doubting what the OP is saying? I don't think he would lie about this and it seems to me that the viewfinder is not representing correctly what the sensor is recording. Regards David
