I have CANON 6D
I want to change may Canon EF 70-300mm f/4-5.6 USM L IS for Canon EF 70-200mm f/2.8 USM L IS II
The difference between the 2 lenses and many or there are different differences
Well, I guess we do not understand the question ... these are two very different lenses. Both are pretty awesome.
Thanks for replying
My own and a simple question I possess the 70-300 L of the canon and I read that the 70-200 f2.8 L II and the milgior telephoto Canon (even your site considers it as excellent)
My question and great difference between clarity between the 2 lenses simply need to change Canon EF 70-300mm f / 4-5.6 USM L IS with the Canon EF 70-200mm f / 2.8 USM L IS II
If you don't need the extra 100mm reach and don't mind the extra weight an size of 70-200f2.8 then this lens is a sure bet, it will never disappoint you. You can always get a 1.4 teleconverter and have 280mm f4 or 2X and have 400mmf5.6.
Optically speaking Canon 70-200f2.8 is a well known excellent piece of gear.
Would the upgrade be beneficial for you? Only you can decide.
I suppose that I would rather decide between the 70-200mm and the 100-400mm.
The 70-200mm is fast and the 100-400mm is long whereas the 70-300mm is neither.
I wouldn't worry about quality - these are all top notch lenses.
I'm not a big fan of tele converters (for the 70-200mm) - why take an awesome lens and transform it into something ordinary.
