Quote:nobody forgot the Tamron/Canon/Sigma/Nikon 24-70/2.8, because it's just a different range and aperture and has nothing to do with those 24-105...120/4 lensesI don't agree. The Tamron for example has terrible AF accuracy (like most of the Tamrons), especially at f/2.8, whereas at f/4 it's amazing sharp - I don't use the f/2.8 aperture actually and also considering selling the stuff.
Nevertheless, in my hands it's rather a very good f/4 glass, than 2.8, at least I never open the Tammy's blades completely, where the Nikkor 70-200 2.8 VR2 is safe at 2.8 as well. So, the Tammy is worth to consider in this comparison indeed. It's about standard zooms anyway.
