Originally posted by DragonLord I'm echoing what others here are saying: The AF behavior you're experiencing cannot possibly be normal. This could suggest a hardware problem with the AF system or its optics, or a problem with the lens itself. I would suspect the former and would recommend that you either get the camera replaced under warranty or have the AF unit adjusted or repaired to fix the issue.
Well, as I wrote, the camera already
was with the Pentax service. They sent it the body back saying there is nothing wrong with it, only the lens was dealigned (or so they say). Currently the whole kit is with my dealer and I am hoping that she sees the situation the same way you do.
What really gets me in this discussion is the huge delta of what people are saying about my observations. While you (and others) say that there is something wrong with my camera, others in this thread seem to find that 1 second or even 1.3 seconds of focus time (which is 5 times the amount you "set") is not only normal but apparently
totally acceptable. That's the reason why I kept this thread going for so long and why I felt so unsure about what to do. The response was so mixed. I'd like to know your thoughts about this (especially why the viewpoints are so different)!
BTW. A regular focus time of more than 1s would be
completely unacceptable for me when I spend more than 1000 Euros on an SLR body, regardless of whether that is normal or not. In a way, I guess I have fallen in love with my K-3 a little. It feels good, it's good to operate, it feels very sturdy and has some great features. I am actually very relieved that my model is broken, because that means I can keep all those goodies without having to worry about the slow AF.
Originally posted by DragonLord As for sports/action photography, I feel the K-3 has lots of untapped potential in the hardware. The 27-point AF system and 86k pixel RGB metering system should be capable of outperforming the Canon EOS 70D by a significant margin, but the AF algorithms seem to be limiting the camera's performance. C&N have well over a decade of experience designing high-performance AF systems for sports and action, but Ricoh-Pentax had only a few years of experience working on a sports-capable AF system. To drive the point home, the
release notes for the last two firmware updates for the K-3 both state that improvements have been made in continuous shooting performance when using phase-detection AF.
I get the point you are making. Still please remember that I was comparing my K-3 to the EOS
700D, not the 70D, which is quite a different class of camera!
Having a real pro-grade Pentax (full frame competitor of the D4 or EOS 1D X) would be great. Even the mid-level SLRs from Nikon and Canon have profited from having these "big brothers". Additionally, the prestige of such a camera would really boost the sales (IMHO) of Pentax SLRs. At the dancing tournament I wrote about, I was the only one there with a Pentax (which in a way is kinda cool too) and I saw a lot of cameras there - even one jerk trying to show off his Hasselblad.
YouTube is also a good indicator. If you search for the Nikon D7100 or Canon EOS 70D (which have not been around much longer), you are completely smothered by reviews and comparisions. For the K-3 I can see something like three or four real reviews (where people actually use a production model) and not a single real comparison. Boosting the sales could be a good idea. But, I'm getting side tracked here.
Once I hear from my dealer, I'll let you guys know.
Kind regards,
Chris
