A friend of mine has 2 lenses chosen and wants to know which one is better. I don't have any experience with either of them.
1. EF-S55-250mm f/4-5.6 IS II 2. EF75-300mm f/4-5.6 III USM
Camera body: EOS 550D
Do you have any experience with these? I'd like to know about image sharpness, focus acquiring speed and chromatic problems with these lenses. They are very low cost, of course. Minor chromatic problems aren't an issue for him. But images should be sharp at all focal lengths. So what do you think? Are these okay for stock photography?
55-250mm standard lenses. Dual tube macro flash and external speedlit...
Here you have 2 reviews of that lens. The reviews of lensen on that site are quite reliable. Myself, I have the EF-S55-250 f/4-5.6 IS II which is very satisfactory for its price (However, I will upgrade it in the near future).
