K-5 AF under tungsten light issue ....
Could it be that not all K-5's suffer from this? I had my first one replaced by SRS last week and apart from the now clean sensor it seems to focus faster, I do not seem to have any FF issues or suffer from AF issues at low light even when I try plus I no longer have any issues with may flash on pTT...

K-5 AF under tungsten light issue ....
http://gallery.me.com/dotandcom/100044/IMGP0062_2 Can anyone tell me if this is an example of front focusing? I had assumed that it was sheer incompetence on my part, but having followed this and other threads I am not so sure. As far as I remember I focused on the organ. I am amazed at the K-5's...

You will REALLY enjoy it. Even though mine might go back due to the spots on the sensor (but the shots tonight don't show them at all), I am totally besotted with the IQ. No Front focus or Back Focus issues whatsoever, and I have not even calibrated the lenses on it. This thing with decent fast le...

Where next for K5 pricing?
I paid full price for mine as a very early adopter. OK it went back due to the sensor problem but I happily paid the price for it to have it now rather than wait for some price drop which may or may not happen. If you wait long enough the next model will be announced and you can wait for the pri...

Where next for K5 pricing?
I may be wrong, but why do some people always associate owning a full frame camera = professional? I appreciate the advantages of full frame. However, as some of the newer APS C cameras are now competing with very high-end full-frame cameras, I think some people seem to overlook this point. Moreove...

Where next for K5 pricing?
I didn't say I was gonna buy one from there did I :twisted: Just the pentax equivalent of a short seller on the stock market :oops: I actually have sold my K7 to fund getting a K5 but didn't bite the bullet due to the sensor issue. Decided now that I'll just enjoy getting used to my K20 (which...

Frustrated by intermittent focusing.......
I am getting increasingly frustrated with my DSLR’s to focus accurately. Last week in Cambridge, my K20D decided it did’nt want to focus at all with my 35mm (it was still AF’ing and beeped accordingly), yet it was reasonable with my 50mm. Both my K20D and K10D both occasionally back focus with my ...

Frustrated by intermittent focusing.......
Thanks Mike, that is a BIG relief. It sounds like an inherent problem with the first generation Pentax semi-pro bodies (and in reality the K20D is only a K10D with vastly improved sensor and controls). So an upgrade to a K-7 or K-5 will sort out the biggest issue I have with the K10D/K20D combo. w...

my thoughts on the k5 and pentax compact digital cameras
I've been browsing lots of websites lately with lots of pentax users dumping on the k5 and compacts.I purchased the k5 and gave it a test drive and it did'nt take long to realize this is one of the best cameras I bought.Compared to my nikon d300 which was my favourite camera and canon 7d I give the ...

my thoughts on the k5 and pentax compact digital cameras
I don't think you'll find many users 'dumping on' the K-5! Best APSC DSLR out there, as far as most of us are concerned. There are marginal issues which a few users have commented on, but that's only to be expected for any high-cost camera. While I will agree about the "dumping on" comment I can't ...

K-7 Noise, noise, noise...
I upgraded to the K7 a year ago from the *istDS. I'm very amateur and casual, rarely have decent photo opportunities (remote area) but I like nice equipment when I do. The K7 is a beautifully designed and made camera, nice to hold and operate. I'm (still) perfectly happy with the *istDS - I get th...

K-7 Noise, noise, noise...
Something else that needs some consideration is that this comparison isn't 'apples with apples'. The *istDS sensor has a pixel density of 1.7 Mp per square centimetre. The K7 has 4.0 (as does the K20) - that's a bit over double the density. That checks out with resolution too, given 14.x Mp in ...

K-7 Noise, noise, noise...
Here's one I took testing a Tamron Adaptall zoom lens, at ISO 320 (as close to base ISO as I could find): That doesn't look too noisy to me. At 1:1 ( ) there is indeed a gritty texture to smooth tonal areas, but I think that you'd have to print it out at 'actual size' (3.1 x 4.6m at 72dpi) ...

Well, I have done it. My Building society account is lighter.
I have made the decision. With the age of both my K20D and K10D getting on and both have 30000 plus shots under their belts. It was time to indulge in something new. Something that will be more reliable when it comes to AF (read my other thread on the frustrations with both my K10D and K20D recently...

PEF or DNG??
Nice description. It is in the TIFF format -- which would normally raise a flag that the data is munged to some extent and thats what always bothered me, but it goes on to say there is an extension to the data to describe the sensor pixel layout. As long as the Bayer filter information is properly...

Lens cleaning paper - thoughts?
Hi, What do you guys think about lens cleaning paper? Do you use it? Any experiences? Thanks!

I use silver Rizla papers.

Lens cleaning paper - thoughts?
I have had some, and they seem fine. But I would prefer a lens cleaning cloth instead, something about the softness that is reassuring.
