Originally posted by Dean31 I just sold my Kr because of the focusing problem. I might leave Pentax altogether after reading the K5 has similar issues. I can't afford the K5II or K5IIS. The K30 looks ok, but I've read it's even louder than the Kr and given all the Pentax focusing issues, I'm just leery and now considering ditching all my Pentax stuff for Canon or Nikon. Any reason to stay with Pentax?
Like I said, I have both a K-r and a K-5. I never have experienced significant AF issues with K-5 and only very infrequently on the K-r. I don't have any other brands to compare them to, but some people think that Pentax AF is not up to par with others like Nikon. I really can't comment on it except to say that I am not a professional photographer that relies on AF. For my purposes Pentax AF is fine. Some people that post frequently here achieve outstanding K-5 AF on such demanding things such as sports. You might want to search the threads for pics if you haven't seen them already.
I could be wrong but I don't think that the shutter on the K-30 is louder than the one on the K-r. The WR body construction is different from the non WR body of the K-r. That in and of itself probably dampens the shutter sound somewhat. Some people have commented to that affect anyway.
All that said, the Nikon D600 full frame can be had for a very decent price right now. It will still cost a bit more than a K-5, K-5II, or K-5IIs though.
