Yes, I would recommend this to a friend

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

This is a very sharp, well built lens for a suprising price. No, its not that white, 5.5 pound EF 200 f/2 L, and it doesnt pretend to be. What it is, IS a lens worthy of the L line, and 5K less than the f/2.

I love this lens! I use it on a Rebel GII and 20D. I've gotten some great shots in low light concerts at 1/60 second and somewhat lower with a monopod. Not too heavy but solid. Autofocus is very quite and easily adjusted.

Excellent quality as you would expect. However, if you're thinking that this 200mm prime will have the edge over an L series zoom, think again. When compared to my original 70-200 2.8L, I found nothing between them. I'm talking optical performance here of course.

Compact and not heavy. Use it for head shot, very sharp wild open. Not expansive compare with other L lens and well worth for money. Also works well with extension tube for close-up shots.

Fast auto-focus; Superior build quality; Super-sharp images

A great, robust zoom lens that produces professional images quality, snapping with sharpness and contrast. If you don't use converters and image syabalization, seek out a nice old, black MAGIC DRAINPIPE!

I bought this lens second hand from WEX at a very good price considering warranty and service that came with it. I use it primarily on a Sony A7R II body with 1.4x and 2x extenders. I bought it originally for photographing small birds for which it is ideal.

None

I rented this lens for a week as part of the seemingly never-ending learning process. I may end up passing on this lens ONLY because as it turns out, the focal length may not be what I truly need.

focus accuracy & speed; colour saturation

Not as long as you might hope; but this isn't a super telephoto anyway

I bought this lens to take portrait of my son and it works good.

Image Stabilization

Too heavy

I like the lens, but am more used to a zoom telephoto so it is taking longer to get used than I would have liked. I miss not having the flexibility of the zoom.
