Sensor Shake Reduction On The Pentax K-7: Too Slow To Kick In? – Duplo:
Well, this is really a mixed bag and perhaps the one place where Pentax has a bug to fix, the SR simply is too slow to kick in, that we now notice is something that speaks as a compliment to the improvement to the AF system, but that really is no excuse.
The solution so far, is to disengage the AF from the shutter and use the AF button for that instead.
That allows me to warm up or keep the SR spooled and have it ready when I hit the AF button and press the shutter all the way.
Slightly different way to work and take a little getting used to, but it solves the issue and that is what matters.
