In the recent German FotoColor is a test of vibration reduction systems. The Sony A100, the Pentax K10D, the D80 with the 18-200VR and the 30D with 17-55IS were tested. The test was done with a shaker. A movement similar to camera shake was applyed with a frequency of 2 Hz and 4 Hz. The focal lenght was about 35 mm (equivalent), the time was 1/2sec and 1/4 sec. First a picture was done without shake, than with shake and shake reduction.
The sharpness of the reference picture was compared to the shaked camera with shake reduction. The resulting sharpness was still:
Pentax K10D--------85%
D80 + 18-200VR---78%
30D + 17-55IS------77%
Sony A100-----------51%
in comparison to the 100% of the unshaked camera.

I can atest that SR really, really, really works. That's what I'm missing when I'm using a non stabilized lens for the 400D in the office. I'm used to handholding at 1/6s, 1/8s with sharp results on the K10D. I can't do it with the 400D and the kitlens and the ef-s10-22.

I agree with the poster, I'd like to see a long focal length test as SR proves alot more effective for telephoto than short focal lengths. :Grin:

Is there any results for K100D? I believe SR of K100D is at par with K10D.

i can attempt some handholdable SR tests with the mighty 600mm. well see how it goes and i will post my image results.

SR really does work well and is proving to be a competitive alternative to IS and VR. Pentax really knocked one out of the park with the k10d and their proprietary SR. no wonder it swept all the prestigious awards within its class and beyond for 2007.

Is there any results for K100D? I believe SR of K100D is at par with K10D.

Unless the SR tech in the K10D is more advanced than the K100D, I'm sure both will yeild the same results:)

SR was one of the reasons why I went Pentax - then there was more instore, great pics + ease of use for MF lenses & i can even mount some of my Nikkors on it hehehe :)

I wonder what's the Next for Pentax?

Unless the SR tech in the K10D is more advanced than the K100D, I'm sure both will yeild the same results:)

The K100D's SR is rated at 2 stops. The K10D and K100D Super is 2-4 stops. :Grin:

Mark,

I wanna see those stabilized bazooka pics. Hehehe.

Again more proofs that the K10D is excellent. Now if the JPEGs would come out somewhere near the DNG RAW's (a firmware update or something).
