Amazon上有人说的，
1) while the lens is listed as 28-300mm it seems to be neither quite 28mm (
the angle of view is slightly narrower than the 16-35mm set to 28mm), nor
does it quite extend to 300mm (the 70-300mm gets a bit more enlargement).
This is not a big issue in normal use since you'd never know the difference
without a side by side comparison, but if you're buying the lens
specifically for either extreme of the range be aware of this. I don't have
equipment to test so you'll have to wait for p

没比过。
300mm缩水其实关系不大，
28mm那边的主要问题大概也不是缩水。
形变，暗角啥的更突出吧。
