Comment on the Tamron's VC at 600mm.....
....... As has been said, the Tamron's VC stabilizing system has it's faults at the long end.......shots taken at 1/1600 sec. are invariably blurred with the VC system "on", so I switch it off!...... but using shutter speeds of 1/125-320 sec.the VC produces perfectly sharp results with no trace of shake/movement ( given a statistical 80% success rate).
I know it is recommended to not use VC at higher shutter speeds......and the system operates at high(ish) frequency.....nonetheless it does seem strange that at the relatively high shutter speed of 1/1600 sec. the VC manages to make consistently blurred images.
During a series of hand held bird shooting I was getting a very good success rate of sharp images with the VC "on" compared to results with it "off" at 600mm @ 1/320 sec.
Overall I would say that apart from the viewfinder image jumps a little, it stabilizes pretty well, the biggest problem is remembering to switch it off again when shooting high shutter speeds and when panning...... a link to an indicator in the viewfinder would be a clever touch......as has the K3's VF hand symbol.
