Re: IBIS test on Sony A6500 and Tamron 70-180/2.8

Thanks for posting.  IBIS, I have read, loses efficiency as focal lenth increases, which is why Sony includes OSS in its longer FE lenses.  So, if your finding estimates 1 EV at 180mm, I wonder whether the A6500 IBIS would yield better results at, say 100mm or 135mm focal length.  That you were able to obtain a majority of reasonably sharp photos at 1/80 racked out seems impressive to me.

One question: is there a difference between APSC and FF when it comes to the amount of compensation required of IBIS for a lens of the same focal length.  In other words, does the A6500/6600 IBIS have to work harder to compensate for a 180mm lens than an A7xx?
