Re: 70-300L change of mind
I think you will have a hard time to find extreme focus breathing –in particular the decrease of focal length- in old non IF designs, but it is very common nowadays. Yes IF is not the only fact which is responsible but contributes a lot – for example just focus by extension (using extension tubes) like in the old days and the effect of focus breathing is nearly gone.
And it for sure isn’t a linear function – it is true that the focal length is measure at infinity but depending on the lens some keep it quite nice until you approach the close focusing distance others start to drop of like you describe it. I didn’t test the Nikon lens mentioned but had to do so with a couple of Canon and old Hasselblad and Zeiss. There is a huige difference between old and modern lenses.
Canon EOS 7D Mark II
Canon EF 400mm f/5.6L USM
Canon EF 70-300mm f/4-5.6L IS USM
