Pictured above from left to right are the Canon 24-70mm f/2.8L USM Lens, the Canon EF 70-200mm f/2.8L USM Lens and the Canon EF 70-200mm f/2.8L IS USM Lens. The Canon EF 70-200mm f/2.8L USM Lens is compatible with the Canon Extender EF 1.4x II and the Canon Extender EF 2x II. The 1.4x yields a still relatively fast and reasonably sharp 98-280mm
They are both strongest at the 24-40mm range and their edge and center performance are pretty much identical. So what you are saying is they are soft at 70mm, lots of mixed reviews with the F4, some say soft, if that is the case i would plum for the F2.8, its all about risk i guess. -- hide signature --.
