Who else are waiting for a firmware update for K-r to fix the FF problem
It could well be that the colour of the light affects focus accuracy as different wavelengths may focus at different point in the AF system. CA in the AF path I presume. In daylight there doesn't seem to be any problem, so we are talking about situations under tungsten light at low levels. Or are...

Who else are waiting for a firmware update for K-r to fix the FF problem
K5 is slightly different, the K5 has an extra sensor that "scans" the wavelength of the light and adjust it. So problems with the K5 and Kr doesn't need to be the same but can be though... But it's normal for AF systems not with the extra sensor to not have a correct focus under tungsten light, ...

Who else are waiting for a firmware update for K-r to fix the FF problem
Hiya, I too have an issue with forward focussing on my K-r under tungsten light. Nearly all my photographs are taken under stage lighting with a fast lens pretty wide open so it was immediately obvious I had a problem. My camera focusses beautifully in daylight. I have carried out a selecti...

Who else are waiting for a firmware update for K-r to fix the FF problem
My K-r also has a similar problem and this is in daylight not indoors. The AF accuracy is not great. Lots of my shots are not focussed properly. It appears to be much better in LiveView however. Initially I thought its just a shaky hand problem but a second and then third round of shots had similar ...

Who else are waiting for a firmware update for K-r to fix the FF problem
Yes - there is an AF fine tune facility in the K-r. Its global to all lenses and doesn't seem to give quite enough adjustment (not for me anyway). I'm looking forward to trying live view and its contrast autofocus - logic suggests it should be absolutely accurate. My fave lens isn't compatible wi...

You cannot calibrate for FF at lowlight/tungsten My comment was on AstraNine focus problems under daylight :wink: only one calibration per lens is allowed. There seems to be only one global adjustment for the Kr. You cannot calibrate for FF at lowlight/tungsten light/halogen, only one calibrat...

Who else are waiting for a firmware update for K-r to fix the FF problem
p.s I don't think Pentax was affected by the Japanese quake/Tsunami Probably not. Either way, my 16-50mm SDM is still over there and not a single word back from them. It's now getting to the point where its of comfort to publicize Pentax's sterling support and service ability. I'm hoping for a fi...

Sensor cleaning?
I've had three Pentax dSLR's. The first was a k100d and was a real dust bug. This body had no shake, so you had to clean the sensor manually. After doing much reading I realised the most cost effective way to clean the sensor was to purchase a small quantity of isopropyl alcohol from a pharmacist. W...

Sensor cleaning?
This question about cleaning fluids consisting of alcohol always confuses me. To my knowledge there are three different alcohols, ethanol, methanol and isopropyl. In this post we have reference's to people using methanol and isopropyl and that Eclipse consists of isopropyl, from what I've read th...

K-5 number 2 after 1000 shots
I know what you are saying about DPR and Rice High, but if you 'skim' through and just use them as an indicator, then search out the 'real' info, they have their uses. One thing I did gain from viewing some of the info on sites like these, was that even replaced K5's were exhibiting the stains af...

K-5 number 2 after 1000 shots
Well it seems my "new" K-5 has a manufacture date of 17th Nov 2010 and apparently it is in the date range Pentax specify as could have a problem. Bit annoying as part of the reason I had to wait 7 weeks was because Johnsons were waiting for brand new stock from Pentax France. Anyway, I emailed Jo...

K-5 number 2 after 1000 shots
My K5 will be replaced with a 4xxxx 2011 build. I don't see why the stain issue should put anyone off buying a K5 as Pentax are doing the right thing. I'm happy to have been an early adopter guinea pig as the service from SRS has been exemplary. I agree, SRS are doing the right thing. Would I be s...

K-5 number 2 after 1000 shots
Early batches of cameras can suffer faults - I seem to recall that the K20D had lines on the image at first? It's one of the reasons I tend to wait a little while before buying a new product. Gives things time to bed in a little and also for the initial peak price to fall back a bit.

K-5 number 2 after 1000 shots
I stuck a white piece of paper to the wall with a small dot (focus aid), set the camera to f20, pop up the flash and take a picture. Then just take a good close look. Some people will say you never use f20 and it's just looking for problems but if you ever come to upgrade and you have a manufa...

K-5 number 2 after 1000 shots
My biggest gripe is the way its dealt with really. I walked into a shop handed over just over a grand for a camera which is now faulty! I should be able to go back into the shop get the fault verified and handed over a replacement. If it was a tv or something from currys that is what would happen.
