K-5 / K-7 : eight raw buffer limit exists

What about the processing from the noise reduction algorithms? including the hideous dark frame. The results of these are included in the RAW file. Although the Dark Frame nonsense is proportional to shutter speed. So yes Higher ISOs could affect processing time. Some noise reduction is done in t...

look who got noticed

Equipped with a 12 MP CMOS sensor, a dust remover mode, a sensor-shift stabilizer, a video mode, a shutter that goes up to 1/6000s and a sensitivity range expandable to ISO 12.800 from top speed of ISO 6400, this entry-level and compact DSLR is an excellent choice to discover the delights of the SLR...

How long til I can get a used Kx for c. £200?

Strange the k-x should drop so low, yet k100d super's are still fetching £200ish... For £250 it hardly seems worth getting rid, given the quality of the sensor...

How long til I can get a used Kx for c. £200?

All of the Pentax DSLRs seem to hold their value pretty well. I was looking at prices for the *ist D a while ago (decided not to bother as despite the extra features it's still an older, lower resolution sensor than my K-m) and they seem to be holding at around the £150-£180 mark for an almost ten y...

The k100d's 6MP sensor produces superb results. I wouldn't be unduly worried about HSM, its where there is a motor in the lens for autofocusing rather than using the drive pin in the camera body. You can pick up an 18-55 for not much money.

But the 10mp sensor would give you more leeway if you needed to crop an image later. You have a PM (top RH corner of the page check "my messages")

K7 Battery Depleted

I think with everything running there is quite a drain on the battery (even though they have little internal resistance) so the voltage will drop. The sensors basically measure the voltage and guess what's left in the tank. So with live view going, the sensor going, the AF motor going etc lots o...

Falk's Pentax K-5 Hands-on preview

No but good non the less though. It's btw interesting to read that the sensor actually goes up to ISO1600 and the camera can push it higher. Most likely it's the same for other camera's so I wonder how much there is to gain with shooting at high ISO and RAW.

Falk's Pentax K-5 Hands-on preview

I'm presuming that the ISO upto 1600 is done by altering the gain of the sensor, and above 1600 it's done by digital gain. ( Both methods of course will boost noise ) Yes with the K5, I said that I wondered how it will be with the other camera's. Where the limit is of the sensor gain.

Bike race camera/lens conundrum

... this boxing day what would I heft around all day if I could? Seeing sense and wanting Pentax A K-5 and what lens ? The DA* 60-250mm F4 ED weighs the ton or tonne as we have it over here now The 55-300 is still only a consumer effort, what else is there ? 50-135 too short... Tamron, Si...

double kit lenses or body plus another

The 18-55 definitely does not make the most of the k7 sensor (not tried the 50-200). Very useful for wet weather conditions though, and it's probably good enough most of the time to be honest. My first copy was very soft on one side, and needed exchanging.

K-5 in Canada.

I'm tempted, but I'm also tempted by another camera, the one with a very large sensor.:twisted: And my wife said I can only get one camera this year.:( I'm still trying to find a way around that...:mrgreen:

K-5 in Canada.

I'll keep the K10D, there is no Pentax camera that can beat his low ISO performance so the camera will be perfect for studio use and landscapes (if i'll do them). The sensor on the K10D seems much better suited to macro as well .. which is why I bought another one.

K-5 in Canada.

No you're right about that, i also never really liked the look what the CMOS sensor produce. The CCD seems the be cleaner and truer somehow. I hope the K5 is better in that aspect because the sensor is from Sony and not Samsung, don't know if that might have something to do with it?

K100D Super queries

Two questions:- 1) I recently got water into my K100D (in the nav keys and also the SD card) but after some gentle heat from a distant hair dryer (hand-warm) it seemed to solve the problem. However the next day I discovered that while the camera appeared to work normally, all images were offset ver...

K100D Super queries

Nigel, The K100D super was minor upgrade to the K100D. It added SDHC and SDM lens compatibility,dust removal and higher iso range while retaining the same sensor etc. The camera is a bit of an oddity as there has never been any firmware updates for it.

Catzeye Focusing Screen delivery/cutms question..

I have a KatzEye screen in my K20 that I ordered direct from KatzEye last year (there are no UK agents as far as I know). Yes it is expensive and I was charged the import duty by the shipping company. I'm not able to compare it with anything other than the original screen so don't know if I could ...
