I wonder if OSS and focusing compete for the processor. If so, turning off OSS might improve focus tracking on fast moving subjects. But if OSS and focus don’t compete there may be no advantage to turning off OSS. The situation may vary with manufacturer or model.

Since Sony only recommends turning OSS off for tripod use, perhaps there is no advantage to turning it off for any other situation. I don’t like to speculate, so I‘d like to think of an easy DIY experiment that would answer the question for my particular model.

But it’s nice to have a stable viewfinder image, so I’d rather leave OSS on unless I have evidence that it compromises focus.

Yes. I shoot Whiskered Terns and they certainly qualify as erratic.

The strike rate would be far lower without OSS.

But I may give it another try. The last time the lens AF was defective and so not a good test.
