I have been needing to use quite an adverse set of adjustments when hadholding with my 55-300 esp at 300mm, for eg - in average outdoor light not summer, to keep my lens at anything near to its sweet spot of f8-f11 and yet avoid camera shake, i am needing to select 320/sec or higher, this in tern is requiring an Iso of 400 minimum - probaly affected by me adding 1 stop of ec for ettr as my camera tends to lean towards underexposing for the shadows and keeping the highlights from blowing out, i feel i also need the ettr to help the noise at 400 or more.
Any other ways around this as it sometimes can be a viscious circle
P.
. It's not unusual.
