Stock or after market? Dumb dumb no understando.
I have the cheapest L lens for my 70-200. It's the F/4 version with No Image Stabilisation. Can get one for around £300 or so now I think!
70-300 has more range, but that's about it. the 70-200's are far quicker, have a constant aperture and have far better optics so give far greater image quality. Definitely recommend!
I meant, did it come with the camera body (mine came with a 18-55mm, or did you buy it seperate
I really REALLY want the EF 24-70mm f/4L IS USM.
I dont really use the 70-300 much to be honest, and when I do it's for architectural stuff and rarely moving objects. But, that is what i got it for so does what I want.
