Maybe I'm not looking in the right places, but I haven't seen many reviews of the 70-300mm f/4-5.6 IS II USM. The one that seems most-referenced is The-Digital-Picture's , which touts the lens's "price-to-performance ratio".Same here. My 70-300L gets little use now that I have a 100-400L II, but I still want to keep hold of a 'travelling light' tele zoom. If the new 70-300 had been good enough I might have traded down, but the reviews are consistently, well, unenthusiastic.I would switch if it meant no loss of IQ. Unfortunately it will as by all accounts the new one isnt much better than the old one, and i hated mine when i had it.Would you consider switching to the new 70-300 USM II if it didn't mean much (or any) sacrifice? And have you thought about using some kind of cover?When using my 5Dmkiii I tend it go out with my 16-35 f/4, 24-70 f/2.8 mkii and 70-300L. All fits in my small bag with any lens thatched, with hood on all lenses even when stored (as i dont tend to take lens caps out).
I just wish the 70-300L was black like all my other lenses.
