is regarded as one of the best three prime lenses that Canon produce (Along with 85mm f/1.2 L USM and 35mm f/1.4 L USM). The images from this lens are very sharp, contrasty and show a lot of details even in wide open at f/2. The depth of field is very shallow at f/2.

sharpness wide open; built-quality; appealing bokeh

not very versatile (prime lens); slow AF tracking

This lens combined with my EOS 5D Mark IV is ideal for on location and studio portraits and event photography. Great bokeh and light weight vs my Canon 70-200mm, f2.8 and very fast auto focus, with very sharp images even though not image stabilized and all for $999.

This is an absolutely fantastic lens and exceptional value for money. Every single photo I take with this lens gives me that 'wow' factor. Not only are the images razor sharp wide open, the creamy bokeh and shallow DOF it creates at f2 gives a very unique look to photos especially when combined with...

Consistent Output; Durable; Quick Focus; Sharp Focus; Strong Construction

This lens has graced my camera permanently since I bought it - it's an absolutely beautiful piece of kit and the additional 2 stops of aperture over the zooms I was previously using has brought back a degree of creativity to my photography that had seemed to be withering.

If your thinking of it. Let me just say this, best prime ever for portraits on a FF . If this is you then get it.

Yes, I would recommend this to a friend

Fast; Sharp Focus

None so far

I bought it for my Canon 40D. No regret at all. It is pretty sharp and focuses really fast. It is very well built but not as heavy as the 85mm F1.2L. It is one of the least expensive "L" lenses. It takes time to get used to the 1.6X crop if you use it with none-full frame body.

Sharp!!!Sharp!!!Sharp!!! Great Colors and Contrast!!!Excellent Bokeh!!

None at all, but I would like to see it comes with IS; The lens hood is awkward to carry around

...this lens is THAT sharp. I took this lens for a "walk" and came back with some unbelievable shots...they were that clear, in focus and super sharp with THE smoothest, buttery bokeh I have ever seen.

This is a great lens, the focus is quick and accurate as well as being one of canons best primes. Highly recommended.

Well, first of all, this is a 135mm lens. That means that, this is somewhat considered as a telephoto lens. If you have a Full Frame (FF) camera, this is the lens that you should seriously consider.

The f/2.0 aperture; speedy focus; and solid build

No IS; but not really an issue anyway
