AP's Test of Shake Reduction Systems (incl. K7)

This weeks Amateur Photographer magazine includes a test of a number of both Lens and Sensor (In-body) shake reduction systems, including a test of the K7 using a Sigma 50-200 both with and without use of Lens-IS and Sensor-IS.

In general the results showed that the Lens (Optical) IS systems performed significantly better than the Sensor-IS based systems

The tests were based on sets of 10 images of a resolution chart taken hand-held at 1/8 & 1/15 sec, assessed both for suitability for printing at A4 size and the measured resolution.

The results for the K7's Sensor-IS were rather poor, and in fact were by far the worst of the 3 Sensor-IS based systems tested, the others being the Olympus E-620 and the Sony Alpha 500.

For example, for the K7 at 1/15 sec only 2 of the Sensor-IS shots were deemed acceptable for printing at A4 compared with 9 for the Lens-IS shots. At 1/8 sec none of the Sensor-IS shots passed the test.

The Panasonic G1 performed particularly well, yielding 10 acceptable shots using its 14-140 Lumix Vario Mega-OIS system

So ..... is it worth using Pentax Sensor-IS for general use? It seems not !
