Uma lente fantástica!!!!!!

Exelente em todos os sentidos

Nada

I bought this lens to use on a series of adventure cruises to the high Arctic and Scottish Islands. I was torn between this and the 100-400 L zoom. This lens was lighter and had a constant aperture.

Lightweight; Rugged

Very sharp pictures - if your OK with no zoom, It is a great lens for a decent price. I would highly recommend.

Shoots sharp images; very quiet IS; great colour and contrast; 2X teleconverter; which provides plenty of manual focussing

No zoom

This lens is as sharp as a tack without the added weight of it's big brother, the f2.8 version. When you are carrying a load of equipment on your back you'll be glad you have the 300mm f4.0 instead of the heavy ones.

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

I bought this lens as I needed more pulling power than my 70-200 f2.8L IS could give me. Initially I was surprised how compact and lightweight it was. It is no bigger than the 70-200 f2.8 and it is noticeably lighter too.
