Pentax K3II Failure

The camera came back from repair. The failure was Integrated Circuit protector. Why the fuse has blown nobody knows. No other fault was found.
Parts replaced are:
Cover Plate double stick part No - 0077240 B81
Cover Plate ASS'Y part No - 0077760 0-B80
Shutter Code FPC part No - 077760 T75
If some one can make sense out of all this please let me know. I wonder what are all these parts replaced and how are they connect to the circuit board fuse .
The camera is working fine and the moment. I am quit happy that I got it brand new.
Thank you for your input.

It was really strange for me too, because it was a failure on a new Camera. I suspect it is a defective board that was simply not detected durning manufacturing. My Pentax KX was ovet 9 years old with over 40 000 pictures when I sold it in mint condition. And I never had an issue with even once.

Thank you for the info. I guess you have a point. I worked before also for the service industry I use to sell phones back 15 years ago so at that time the turn around for repair was no longer then 2 weeks usually with in the 1st week the repaired phone will be back. Now to the point of home fixing. I wonder if you have the electrical schematic for the K3II because in my experience at least for me with no schematic the chance for successful repair is quit small. If you do have them please share. The last lens was brand new Tamron 70-200mm f 2.8 that I bought since it was so well recognized on pentaxforums.

So I got an update for the repair status. Apparently it is a big job to fix it. I was not told what really has failed in the unit I guess will find out once I get it back. Now I am thing next time I buy Pentax to buy a used unit that has passed over 10 000 shots so if there was anything faulty from the factory it would have failed with the first owner. Dealing with repairs is not fun especially when you have to wait weeks at the time to get it fixed. I never expected that a warranty can take so long.

I am not a pro so I believe that I can address your issues that you are having with the Camera. I do have K3II and I agree with you that in full auto the pictures are fare away from what they should be. But this was not the intention of this camera. You will get the best result if you start using the other settings just look at the manual and use the simplest of all of them where you allow the camera to do most of the work and you select only one thing. Ideally if you find Pentax K-X instruction manual all the basic features are explained with examples this what I stared with. K3II manual does not gives examples and could be hard to follow as a beginner. Don't start with RAW files it will make things more complicated. Learn the Camera first and later you can deal with RAW files. I use Affinity Photo it is not expensive and it is easy to use. Again easy to use it is just what I thing it has a learning curve.

I did search around in the forum and I cannot find anyone having all this issues appearing together in the same time. I wish there was detail diagram where I can see what is causing this type of behaviour. Any way if any one has better idea then me please post.
Thank you.

Today I experience something really strange. I turned on my camera and my screw driver autofocus didn't work also the mirror didn't open and the aperture would not move from the on off toggle switch. The camera will just take black frames . It will not even tray to move. I restarted the camera nothing. Change the lens same thing. Reset and refresh the camera no result. Initially I was under the impression that all 3 functions are operated by one motor but after checking on Pentax web site they all have independent motors. Lucky for me the camera is less then one year old and I shipped it for repair under warranty. It looks like a control board has failed because all mechanical components are dead.

Lens focus calibration guidelines

I have a K3ii and it came with 18-135 DC WR lens. I had a K-X before for almost 10 year and I was using with 16-50 DA* . So in my case the DA* lens was good and on focus also I have Sigma 30 mm art and I never had a problem but once I used the new Pentax lens I had a big issue. First the lens has no scale to show you where is the focus also and different focal length the focus is also changing. I tried using it for astro tracing but every time it was out of focus. I tried focusing on a illuminated object to infinity then locking the focus but nothing ever worked. Today I discover this internal adjustment for the auto focus and now finally after I put the lens to -10 it became sharp. Obviously the lens gets really soft once you start looking in to the corners but this is to be expected for a zoom range the good thing is that it is sharp in the centre . I almost sold the lens brand new for a 100 $ but now I discover that the lens is not that bad.
I hope this helps.

Kp or K3II

I had the same dilemma and i bought the k3ii. I find it to be better build better grip and a faster shutter. This is just my opinion. Apparently KP has better really high iso i looked at picture samples and it is better. But at that level they both look bad because there is so much noise that make the picture useless.

Does the D-FA 28-105mm on K-1 compare favorably against the DA* 16-50 on K-3?

Well its so hard to say without side by side samples. I own 16-50 and because I like it I choose k3ii over K1. I know about resolution but the bottom line is 16 - 50 works really good for me. If I was going to use it professionally I would not use a zoom lens at all.

Before you change the camera get a high quality 1.4f lens this will make the biggest difference. This is the short answer . If you also upgrade the body then you will see even more improvement. If you go to full frame you will need a new set of lenses because of the dark corners.

You can buy a brand new k3ii it is available in Canada. Officially it is discontinued but it looks like it is available. I just bought one a week ago.
