K7 K5 Gross Over Exposure Problem
Hi Billy, when you download the firmware, there's a file attached which tells you how to go about it. I understand your concerns re updating the camera and the warranty, problem could be that Pentax will come back and say, " need to update the firmware " to see if this solves your problem, As ...

K7 K5 Gross Over Exposure Problem
John - Thanks for this comment - however between the white out and today's shot, which I put on the Gallery, taken immediately afterwards, there was only several seconds. Most certainly the lens was not taken off then fixed back. Since this defective shot, there has been one change of lens to the...

K7 K5 Gross Over Exposure Problem
Thanks for the help. I will email the images. Plus I had a different example this morning (with a different lens) with one exposure of 1/200th followed by one of 1/2000th under identical conditions with no obvious (to me) cause - I'll send those too. Thanks for the contributions so far. I have...

K7 K5 Gross Over Exposure Problem
Okay dokay... DR_O4030 = Centre Weighted metering, no AE-L. 11.1LV DR_O4031 = Centre Weighted metering, AE-L enabled. 14.8LV. The exposure information doesn't tie up with the scene - so I suspect you pointed at a brighter area by mistake and pressed the AE-L button :P Both had -0.3EV compen...

K7 K5 Gross Over Exposure Problem
All very interesting,Especially as today I had some over exposures with my K20D, I finaly noticed that I must some how pressed the +/- EV Compensation button whilst turning the front dial and in doing so had set + 3 compensation. HMMMM I never had this problem with my Brownie Cresta back in the 50s.

First DSLR...please help me...pleaseee! :)
Hello Pentaxians! I (finally) decided to spend some money on what will be my first DSLR! Even if I'm quite young I always used film SRLs and my favourite is my lovely MX... During these years I collected lots of cameras and lenses paying nothing, now I've got 2 Spotmatic, the complete K ser...

First DSLR...please help me...pleaseee! :)
GIMP will do everything you need, though I am not an expert on its use. It reads RAW or you can use a plugin like UFRaw for extended support. I own a K-x and really shoot low light often.. but I prefer the K20D. Not only is it nicer ergonomically, I find the RAW files take a lot more manipulatio...

Is 10 units of back focus unusual?
I have finally worked out that my 43mm ltd is back focusing and the '3 battery test' reveals that it needs +10 units of correction. At first I thought it was an issue with my K-5 but it is the same on my K20D. It seems right at the limit of what we can adjust in camera. Is there anyway to adju...

Is 10 units of back focus unusual?
Hi Ken I really only have the 43mm and the 18-135 for my K-5. I get 'soft' shots from the latter too sometimes but am not sure if that is user error. I tried setting the calibration with that at various focal lengths and decided that it too needed +10 for table-top battery shots at around 35mm...

Is 10 units of back focus unusual?
I had to dial in -10 on my K20D for my DA* 50-135. It needs -5 on my K-5 My Pentax-A 50/1.2 need ore than -10 on the K20D so I ended up adjusting the overall AF in debug mode and recalibrated all the lensesso they were all within the +/-10 range.

Is 10 units of back focus unusual?
I had -10 on my Tamron 17-50. I put up with it for ages... no good. Sent it to Tamron and they tinkered with it. Now I'm on +1 and it's lovely and sharp. There is nothing like lens calibration to muddy your thoughts on image quality. "is it me?" or "is the image good enough?"... you'll be asking...

Is 10 units of back focus unusual?
Thanks for the responses; makes me feel slightly better. My questions now are: (a) where do I send my Pentax lenses for calibration? (b) What do you mean, Smeggy, that you can adjust the overall AF? Is this some debug mode thing and is it available for the K5. if so, how? Thanks, I am fe...

Is 10 units of back focus unusual?
Just another comment. Whilst I was doing my somewhat desperate set of 'is the middle battery in focus' tests earlier, (18-135) there was one set where they were *all* way out of focus, i.e. for 0,5 10 adjustment. I could put that down to perhaps I was kicking the tripod except the live view shot was...

Is 10 units of back focus unusual?
Smeggy I didn't think that the 'Apply All' and individual AF adjustments were cumulative? Do we have any proof that this is so, other than me doing another barrage of test (I think I might use sausages next time instead of batteries :-) !! ) I assumed that any 'Apply All' setting was overri...
