Another bad K-3, what is with this.

Two big events this weekend that I am shooting. I finally gave in and ordered with B&H. The K-3, DA 50 1.8, Sandisk extreme card 32gb, d-bg5 grip, and the DA 10-17mm. All for $1743.90. Got it all last night, fast shipping, good job B&H. Last night i took 280 pics trying to set up 6 favorite lens's to focus properly, no luck with this camera. Focus never stays the same and is all over the place. When it hits right the picture is very sharp and great. Sending it back to B&H for replacement. I am sure it is not me because I take a lot of pics, mostly in dark night clubs. I own the K100, K7, Kr, K5 and the K5lls, so I know what I am doing. Love the K5lls. Wish me luck.

My two most used lens are the Tamron 2.8 17-50 and the 2.8 70-200, then the FA 50 1.4.

OP of three posts only, one in Pentax SLR forum to 'complain' about the K-3 and/or his/hers lack of patience:

  • To read similar posts posted here before and many resolutions from people who were more studious and patient in understanding the K-3
  • To justify his/her own worth by respecting other people's time
  • Not to unnecessarily start rampages, and endless repetitions of same ill-conclusions about the worth of photography equipment purchased

There are a lot more AF options on the K-3 than previous Pentax bodies. Are you sure it's a defective body and not a setting? What focus method are you using? Which AF points?

Re: Another bad K-3, what is with this.

I too was ready to send my K-3 back the next day after using it!  But with some better photo techniques that I have forgotten, I am very happy with the focusing and quality!

I always check my gear with manual focus first, looking for vibration (mirror-slap, etc.). Then I AF on a flat surface (brick wall) to check repeatability. My K bodies each have a personality of their own, but as you say "Patience" serves them all. Default settings on gear can be a pain, especially the "easy modes". You'd think high-end/semi-pro/flagship gear wouldn't come in default setting "Dinghy".

Re: Another bad K-3, what is with this.

Thanks Dan and Gosman, I'm quite sure it is the body. I shoot AF>S and I always use the center point only. I have over 5000 clicks on my K-5lls and love it .  I shoot a lot in quite dark clubs and bars and the k-5lls focus is great, I love it. After shooting so much with the 5 and the 5lls, they are like my third hand in the dark.  I have a lot of faith in the k3, but I think i just have a problem with this one. I will get it replaced.  I'm quite excited about it. My 5lls will do great this weekend like it always does, even at 0 degrees as it will be here in Green Bay, WI. I am reading this site probably 300 days a year and love all you guys for all you do on here. Keep up the good work.

I'm amazed that the fanboys will never give up. The K-3 has less than a quarter extra resolution over the K-5 etc. It should not be rocket science to get as sharp shots with it as you can with the other models. If enough of them get returned and end up in landfill Ricoh might get the point that there is something up with it.

Too bad, sounds like you got a duff K-3 alright. Mine's in for service now, had the runaway mirror problem that first showed up in K-5's.

Are you trying to say that all K-3's have sharpness issues? If so, I can assure you as an owner that you are wrong.

That's actually a good one. You have to try it yourself.

But if he is trying to say that SOME K-3's have sharpness issues that are corrected by a trip to Pentax, then I can assure you as an owner of one, that he is correct. With all the reports so far, there can be no doubt that a significant number is K-3's have shipped with problems.

Completely false; all we can say is - like every camera ever made - there are some bad units out there and there is always a chance of getting two (or more!) in a row. Since you have no real data other than a few reports (nowhere near enough to be a real data point), we have absolutely NO IDEA how many K-3's have shipped with problems. It's entirely possible that the K-3 has a high defect rate, and it's entirely possible that the K-3 has a very low defect rate. Only Ricoh and those who service these cameras knows the truth. However, I sympathize with the OP, and understand his frustration.

For what's it's worth, my first K-3 was a dud. It had a remarkable back focus problem that tweaking did not fix. I took it back to the store to test with different lenses.

With the DA* 16-50 f/2.8, it had the same problem. It only took about 3 shutter clicks to convince the sales person. -7, +7, it didn't matter. Exchanged it for another one and problem fixed. I haven't looked back since.

As for the lack of sharpness some are complaining about, I recall when the first few Nikon 24 mp were released (D600, D5200, D7100), users on the Nikon side of the house had similar complaints. There is definitely a bit of a learning curve with 24mp sensors. I haven't observed those problems with my K-3 (the second one that is). It's one hell of a camera.

Re: Another bad K-3, what is with this.

And that, is why when prices drop, you grab a backup body. I'm not rich, but I love my hobby. I'm not going to pine over unfocused photons because the QC guy had a liquid lunch. Lens come off, then on the backup, I'll get out the warranty card later. Better to take pictures, than antacids !

I did exactly the same thing after jumping to the D7000 from the D200. I did the same thing and took it back to the store. I was SOOO disappointed. A couple of weeks later i went back to the store and bought it again

It wasn't the camera, i just didn't know how to use the "new" one.

But it is possible your camera was bad too

That is what I was trying to say. For whatever reason there appears to be either a design or QA/QC problem with the K-3. It is like the K-5 sensor stains episode all over again. Blaming it on some 'extra learning curve' needed to cope with the extra 20% resolution of the sensor or on user error is stupid. People seeing the problem are often not beginners. I for one will hold off buying until this is sorted by Ricoh.

Similar complaints?  D600?  No, I went through that one and it was different than this.  My D600 = no problems at all, but one couldn't tell from the 1000s of dust/oil on the sensor threads out there that it was a decent camera.  Ultimately, this drove resell value down and forced Nikon to bring out the D610.  Trying to say (as some are, not necessarily you) K3 has general QA/QC problems based on this little volume and usage seems a bit ridiculous to me.

There is definitely a bit of a learning curve with 24mp sensors. I haven't observed those problems with my K-3 (the second one that is). It's one hell of a camera.

Re: Another bad K-3, what is with this.

Sorry you got a bad one.  Since you got it from B&H, I doubt it was a previous return, but did you run exiftool on the shutter count when you first got the cam?  Well at least you've still got the, (what did you say?) K7 K5 K5II K5IIs K30 K-01 etc. you can still use.

Cheers.

My K3 is in service for backfocus issues. Kinda disappointed mine had this issue. I'm keen to see if the service department will blame it on the lens, the body, or me.

I spoke to a tech recently and he somewhat indicated that I wasn't testing my focus properly. We'll hello! If I focus on something (like batteries lined up at 45 degree angle) and get a focus indicator on the middle, if I take a shot (even with a tripod and on timer) why is it back focusing?
