Som vanligt går resultaten isär kraftigt mellan olika tester. Den här är utförd på en ovanligt kort brännvidd.
Från DPR:
"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.
Now, I would like to see the test also with 300 mm focal length, a focal length where I have the impression, that the K10D is even more efficient.
