Originally posted by joodiespost okay Guys, I just read up on a post by LeDave saying that there is a new "silent" firmware update that fixes the SR issue. Was this the culprit all along??
I was skeptical of this. I've been following along with the recent silent firmware update thing, and I figured most people were seeing an improvement because they wanted to see an improvement, not because it was actually there. It's hard to test such a thing objectively because test conditions are hard to reproduce.
However, I've changed my mind on the subject. Supposedly the K-7 firmware was silently updated a couple weeks ago too, and I just updated to it this week. It's important to point out here that I never thought there was anything wrong with my camera. I've taken thousands of pictures with it, and I never once questioned the SR performance. So I wasn't looking for any improvements.
But when I went out to take pictures yesterday, ALL MY SHOTS were definitely way sharper!!! It's like a revelation! Shots I was taking at 135mm with 1/10 shutter speed were coming out sharp! I couldn't believe it, it became a challenge to try and get the SR to fail. There is definitely a VAST improvement over the previous firmware version.
So if it's the same for the K-x, then the silent firmware update probably would fix a lot of your blurriness issues.
The "old" K-x firmware was 1.01.05, and the new one is 1.01.07. It still shows up as 1.01 on the web site, and there's no indication that anything has changed, but its MD5 sum is different from the one that was released in early December. You can see the current firmware version of your camera by using PhotoME to look at the EXIF info of a picture you take with it. There's a field called "DSP Firmware Version" under the "Manufacturer notes" section.
This picture was taken with my K-7 at 1/25 and 50mm, handheld in a snow storm with tons of wind while standing in 2 feet of snow and wearing 2 coats and thick gloves.
And this is a 100% crop:
