Re: 55-250 stm vs 70-300 usm is ii on a 90D

I've used my 55-250 with both my granddaughter's SL2 and my 80D and the AF was much faster with the 80D. Its better still with my M6II - haven't had my 90D long enough to report but it will be at least as good as the 80D.

The problem I found with the 55-250 was that if it couldn't find an initial focus it would rack all the way to MFD and then back out. This can seem very slow when you are trying to capture a moving critter. With stationary objects, even a butterfly sitting on a flower, its not an issue. The better AF cameras more often drive the lens in the right direction while the SL2 always seemed to drive it the wrong way. I don't know where your brother's camera would fall on this spectrum. Still I find it a convenient alternative to the 100-400s.
