Originally posted by Class A Do you now acknowledge that there is a problem? For a long time you claimed that your K-5 copy was performing above expectations. Did you change your mind and if so, what caused this to happen? Did you stumble across a colour dependency that you somehow managed to avoid in earlier tests?
I am not sure I understand your questions.
1. I have never said my K-5 *didn't* have a problem. Right from the first post, I said I have found evidence of my K-5 to have a tendency to FF in low light conditions, described exactly what those conditions were, and then compared the K-5 performance with two other cameras. I have also posted photos showing my K-5 exhibiting FF in low EV halogen light situations
2. I never said my K-5 was performing "above expectations." Whose expectations? Mine? Yours? A typical purchaser?
3. I did say that my K-5 did not seem exhibit behaviour that I would consider to be worse than a K10D and a Canon EOS-1D. Indeed, it's focusing ability could perhaps be regarded as superior to those cameras in low light situations (provided either Live View or AF assist was used to do the focusing). Perhaps, in that sense, it is "above" expectations - but to be honest I had no expectations before I bought the camera - I had an open mind.
4. I also said that I have never encountered any issues shooting in "real world conditions" as opposed to artificial test scenarios which I don't consider to be typical shooting conditions. By and large, I am pretty happy with all the shots I have taken so far on this camera.
5. Therefore, I stated that with regards to my camera, and my camera only, that the issues with that I have discovered with low light focusing anomalies are not "significant" - they are not in my mind justification for me returning the camera within it's 45 day money back guarantee period, or to send it in for servicing.
6. The latest round of tests I have done have not changed that opinion. They have simply made it clearer what the conditions for the focusing anomalies are. I still don't consider those conditions to be significant in terms of how I would use the camera. If I had known exactly what these conditions were prior to purchase, I would still have bought the camera.
7. I understand other people may feel different about these focusing anomalies. Clearly they are entitled to do so. My advice to them would be if they are not happy with these anomalies, they should return the camera or ask for it to be exchanged/serviced.
8. My unsubstantiated opinion, and my opinion only, are that the anomalies I have confirmed via testing are probably not fixable by firmware, and may require a substantial redesign on the camera. Certainly, if I am proven wrong, I will be pleased and will download and apply this firmware fix.
9. However, I neither demand nor require Pentax to "fix" these anomalies - in my experience all cameras have focusing anomalies in low light - certainly all the cameras I am currently using at the moment have interesting "quirks" in low light (2 Pentax, 2 Canon, not to mention 3 HD camcorders - 2 Sony, 1 Canon).
10. Until then, I will continue to enjoy using my camera. This Sunday is World Pentax Day, and I intend to join other owners of the K-5 in using it, and I hope I will take a photo (or several) that I will be proud of.
