Sunsets
Probably splitting hairs, but the truly raw output from the sensor has to be processed somewhat to decipher the information and present it as a demosaiced colour image. There is, so to speak, a bare minimum that has to be done regardless. However, there is no application of colour temperatures, s...

K5 Low contrast
I'm really happy with the K5, no excuses any more! :) However I have noticed the images aren't as punchy as my lovely old K10D. Is this just a characteristic? or is it connected with the increase in sensor resolution? Is it possible that the lens can only pass a certain amount of 'information' a...

K5 Low contrast
I'm guessing it has to do with the CCD sensor in th K10D... I recently got my lad a *istDS and there is a certain 'punchy' quality that comes from its images too, in comparison to my K-x... That said... There must be benefits to the newer CMOS sensors...

K5 Low contrast
I agree. The Ist Ds and K10 give a punchier picture - but that is to do with the CCD sensor. I really noticed the difference when I went from my beloved Ds (RIP :cry:) to a K20D. I am used to it now and think the K-5 gives better results than the K20D did.

K5 Low contrast
It's interesting to note that 'Natural' was the default balance on the KX and 'Bright' is the default on the KR for jpegs despite hving a very similar Sony sensor. I'm not surprised at the difference between CCD and CMOS sensor models as both have very different characteristics I understand. I...

K5 Low contrast
I seem to recall that 'Bright' was the default when I bought my K-x? I quickly changed it to 'Natural'. I have compared the three cameras using the same lenses and the IQ is very different on all of them. The K-x is fairly close to the K-5 in terms of the character of its images, but the K-5 ha...

K5 - Exposure bracketing for HDR
JAK, sorry if I didn't make it clear. I was using exposure bracketing (not the in-built HDR). Thank you, your suggestion of using Av mode works. I had wondered if the exposure compensation behaviour varied with mode. Apologies for being too lazy to experiment before my original posting. A note in...

K5 - Exposure bracketing for HDR
Smeggypants, I think you are probably correct that the 14-bit output should normally be enough for HDR enhancement within the 'tasteful' range, but I'm new to DSLR and am still trying out what works best for the results I'm after. Some HDR purists (HDR and 'purist' don't really sit comfortably toge...

K5 - Exposure bracketing for HDR
It's not a technical matter, Smeggypants, it's an aesthetic one. Doing all these things gives different pictorial effects, some of which can be very attractive. 1EV or eben 0.5EV steps, usually seven exposures, processed through Photomatix can give some very powerful results. This is an exampl...

K5 - Exposure bracketing for HDR
I think these 'bits' and EV matters are important when shopping for a new camera, but what counts in deciding what approach is realistic in HDR processing, then the key indicator is the histogram - for the original shot this will tell you if the camera has 'got it in one', and if not then you could ...

M lens and earlier, what settings ?
Is it possible a lot of these shots were taken with the lens wide open? If not, I don't see how the exposure would be any more accurate without stop-down metering. That would be my understanding too, Chris. In practice, however, I have found repeatedly that I can shoot in A-mode over a range of 3...

M lens and earlier, what settings ?
Is it possible that this different, and completely counter-intuitive, behavior of the K5 when compared with the earlier bodies could be function of its sensor: in particular its enhanced dynamic range and hence greater exposure latitude? Yes, I'd imagine it could only be the better sensor in that ...

The DOF looks similar in each one to me only 5 links of the hanging chain in focus top and bottom. The original of this shot was just BLACK, but it pulled up quite easily. https://www.pentaxuser.com/photo/nuthatch-30599/large - Take your point, Algi, but there are several points on the m...

How long will your battery last.
What's the third contact with the D-Li90 for anyway? It's the temperature terminal. It is normally referenced to the common or 0v (-) terminal. Should a fault occur or the charger fail and cause an overcharge to the battery, the temp internal (to the battery)sensor detects the rise in battery temper...

How long will your battery last.
quote:3496ace15f="ChrisA"] Have you tried another charger, it wouldnt be impossible that its not fully charging the battery? Now there's a thought. Haven't thought about that one since I returned the original K-5, which did have a different charger. [/quote] I've found several, but they seem ...

K5 vs M4/3
Well, I for one would have found this thread of great interest if it had stuck (or been allowed to stick) to it's orginal purpose. As it is, I'm none the wiser about users experiences of the two 'sensor sizes' (not going to name names for fear of retribution.

K5 vs M4/3
Maybe it's the wrong question Pete, as 4/3 cameras are generally intended for a different purpose to the K-5. The question I have is how can the Olympus E-5 have a smaller sensor than the Pentax K-5 and yet end up more bulky and much heavier...that to me doesn't make sense. Then we move to thi...

K5 vs M4/3
I guess a M 4/3 owner with a 200mm lens on or a KR owner with a 300mm lens will still need a big pocket for their camera. The Pentax will have a stop more control over depth of field I guess just like APSC to 35mm size sensor difference. The joy of my Pentax is 800 and 1600 ISO turning out go...

K-5 - wow!!
I'd been asked to shoot a friends wedding and didnt feel that my K-20/GX20 was upto the job so hired i a K-5 and 16-50 2.8 from SRS. All i can say is wow! The image quality, autofocus speed and in particular the dymanic range and high iso performance left me speechless! With my K-20 at iso 320...
