The K-x Blur Issue

Go along this thread for what a K-x user has reported lately for the problem, with various comparison photos posted, and the related discussions thereafter:-

http://forums.dpreview.com/forums/readflat.asp?forum=1036&thread=35716276

A conclusion can be quite conclusively made, that is, the blur issue seems to be existent for the K-x and at least many K-x units are affected. Shots that are taken with shutter speeds in between 1/60th to 1/400th (both not inclusive) suffer most from the blur, which can be easily seen when the pictures are viewed at full size.

And, also as pointed out by one of my Blog readers recently after the posting of my latest shootout test with the K-x, shots that were taken in the above suspected problematic Tv range do really have some blur, so that the pixel sharpness and image quality are degraded. Whilst I do agree that the pixel sharpness is not good for most of the test photos with the K-x in that particular test, I think I need to do a more systematic and scientific test with SR on and off and make comparison shots at nearly the same time so as to confirm the problem later on - that I will do it shortly, as soon as possible.

Btw, if the issue is really confirmed once again, it seems that it is just a design issue/latent defect more than a QC problem, as there have been so many K-x users whom have reported the same problem so far, already..

Just how many of these "my frist dslr"-people have actually read the manual and wait until the SR-symbol is visible in the finder until they pull the trigger? If you take your pictures while the SR-system is trying to stabilize motion blur will occur. Just a thought.

If it is a faulty camera, shouldn't it also have blury images if used on a tripod at the same shutterspeed? It should be fairly easy to test it that way.

Great point, camera "driver's license" certificate might be considered before paying attention to all these (valid???) complains... :o) Even cameras need a degree of skill to be well used!
Sure, I think I (and many others as well) just don't know how to use our cameras!

RH, my comment has nothing to do with your skills, rather with some "problems" from users (often in DP threads) what never even consider read the quick start and just purchased their first dslr "best family camera of the year" K-x.

Than they want to update FW and it freezes in the middle of update because it ran out of power and they blame the camera...instead of almost empty rechargeable old batteries used to save the Li what came with it.

Or soccer parent what has K-x camera with 50-135 on the neck (strap) and while bending to give kids stuff or adjust their gear, bangs/smacks the life out of little K-x with SDM and complains it stops working... have seen it and was just shaking my head...

So, I'm having on my mind that kind of a user...
Well, of course there are always novice users but the camera and the camera company should always make it fool-proof, especially for an entry level camera! :-)
When you mount your camera on a tripod, the SR should be turned OFF.
oh..I am the person both in that two thread that u mention in this post.

I exchanged a new one a few days ago. becasue I only bought for like 3 weeks. now I think everything is fine.

people attribute blur problem to user's technic is because u never get one. if u get one, u will know how frustrated it is.
test is very simple. set on tripod. try different shutter speed, then point and shoot. any people can do it. I do not think u can still conclude that is user's problem.
