Hello everybody,





I have sometimes a need in my photography for the followings:


- Taking picture of people in the streets, but not faces exactly and without disturbing people


- Preserving the bokeh and blurry background


- then Shooting at not so close objects





So, I have been thinking that I like to get a new lens with higher focal length. Then I thought of getting a tele lens and have been reading about different models.


By now, what I have in mind is a "canon70-300" lens (or tamron, sigma..., don't know exactly if they are much worse).


but I don't know yet if that is the best choice. Maybe I have to spend a little more to get a "70-200 f/4" or even another model that I am not aware of (maybe buying a 24-70 or 24-105 is also an option).


Any ideas?





Thanks





Cheers,


Keivan Zavari





P.S: I have a canon 450-D and normally I shoot with a 17-85 or 50mm f1.8... (so still amateur)
