The fastest 135mm telephoto lens in its class, the Canon EF 135mm f/2L lens is ideal for indoor sports photography and portraits with background blur.

The lens also offers two UD glass elements that help minimize chromatic aberrations, giving your images outstanding sharpness and color. Other details include a 3-foot close focusing distance, an 18-degree diagonal angle of view, and a 72mm filter size. The lens--which is compatible with EF 1.4x II and 2x II extenders--carries a one-year warranty.

From the Manufacturer
One of the finest lenses of its type in the world today. This magnificent telephoto lens uses two UD-glass elements to provide incredible sharpness and contrast, even wide-open. It’s perfect for outdoor portraits, but comes into its own in low-light situations. It focuses down to 3 feet (0.9m), and is fully compatible with both the EF 1.4x II and 2x II tele extenders.

Long and Fast
A telephoto lens is essential to any serious photographer. For sports action, you will need a fast shutter speed and a long focal length. A large maximum aperture allows a faster shutter speed. In this telephoto lens line-up, the focal lengths range from 135mm to 300mm. If you want compactness, choose a lens with a smaller maximum aperture.

Customer Reviews

135 f2 is amazing
Everyone gives this lens a rave so maybe i should approach this terrific lens from a shooting POV.

Shooting wide open at f2at 135 gives your pictures a distinct quality you would never get from zooms, there isn't a zoom at this focal length that is this speed either. A few primes come close but they're nowhere near as sharp wide open.

the af is fast and very accurate and the lens has a great feel on a 20d/5d/10d body even wo the battery grip of the cameras.

Close up magnification of .19x to.21 therabouts is a nice bonus of this lens, letting you get closer wo being too in your face for tight headshots.

I always felt that photographers usually have a sweet spot when shooting certain things like some portrait photographers like the distance the 85mm gives them when approaching a subject, turns out I'm liking the 135 focal length quite a bit for headshots and the 85 for torso and head shots.

One thing I like about this 135/f2 combo is that there's enough DOF to get most of the main subject in view and focus but the background will still be blurred out. It's really great when you want the subject in focus and nothing else, as opposed to the 85 1.2 parts of the subject could melt into the background resulting in images that be a little too ethreal for some tastes. Couldn't you just stop down the 85? Sure but the relationship of the foreground to background would still be different with the 135.

The 135 f2 can give a result that's juuust right. The backgrounds just a little more compressed with the foreground but the foreground is sharp but the background is gone. Almost like you lurred the background in photoshop. But you'll never get the same results from blurring in photoshop, for one thing the highlights would get muddied in a blur treatment in PS while the highlights stay clean at f2.

Don't just use this thing for portraits, use it the way you would use a 50mm and try and frame as such, again the focal lenth and wide aperture will give an interesting result. I basically use it for candids and portraits during a wedding.

Fantastic lens, very sharp, very handholdable, the focal length is terrific for portraits and the bokeh is very beautiful, equal in sharpness to the 85 1.2 or any of Canon's $5k lenses. This is probably the best lens you can get for the price, the only lens I've used with better saturation and contrast is the 35 1.4L.

Downside: Not as handholdable as the 50,35 1.4 or the 85 1.2 during low light situations due to it's focal length.

One of the best Canon lens for about $1000
I believe this is one of the best lens for about $1000. Forget about zoom lenses even if they are L. This lens is far better than 70-200L in my opinion. It is very sharp at f2 and even more sharp at f2.5. With zoom lenses you have to set to f/5.6 for better result and f/8 to match this lens. It is very well built but not excessive heavy, come with hood and bag, but unfortunately, Canon have decided to remove the hard cases for all the L lenses.

Combined with a Tamron 1.4X teleconverter this lens provide very good optical quality on par with any zoom L lenses at 189mm focal length. Yes I know I lost the convenience of a 70-200 zoom lens. But I am really happy that I decide to change the plan of buying a 70-200IS to 135/2L+1.4X. This not only saves me the money but also let me to get better pictures, especially at wide open. Better portrait lenses, like 200/1.8 and 300/2.8, would cost several thousands of dollars. Trust me, once you play with primes, you will not like zoom anymore.

I am also using a 24-70L to shoot my small kid. After using this lens, I don't like it anymore and thinking about change to primes someday, the only reason preventing me doing that is the 1.6X crop factor of digital camera. A 35mm/1.4L will become 56mm which is really not good.

Order from Amazon with free shipping even though it says not in stock. They shipped mine in 2 days and this happened before even though item stated "in stock soon".

Pros:
Very sharp at f2 and super sharp start from f2.5.
Very fast lens with f/2
Very good bokeh (background blurring).
Overall extremely good picture quality with good contrast/color.
Smaller size, less weight and black color compare to those white 70-200s.
It is a L lens: best build quality, fast/quiet ring USM AF with FTM.


Cons:
No hard case.
No inexpensive.
Effective focal length is 216mm on 10D/20D/Rebel/300D which is a little difficult to use for portrait.

One of the best lens in it's class
Man. what a lens!!! It's not cheap, and I dont' find the 135mm to be a particularly useful focal length with my 20D but after seeing glowing reviews of this one both at [...], I decided to buy one and try it for myself. It's not cheap at $900, but it's worth every penny. This one is an absolute stunner. I cannot believe my eyes at the sharpness at f2 and it improves very little when stopped down. The bokeh is unbelievable!!! I dont' hesitate to shoot at f2 and I don't find it necessary to stop down just to increase sharpness. The size and build is perfect although I don't like Canon's hood design. Why can't they simply make the hood with the same crincked finish of the lens?? Then they would not so easily scratch. It's beyond me. But that's not a problem with the lens itself and whenever I use this lens, I know I have one of the best lenses ever designed. It forces me to excel myself knowing that now,the only limitation is me, the photographer and not the camera or the lens. An absolute beauty. Go try it yourself. I try to shoot with this as much as possible and the results are stunning. I just wish it came with weather proofing and Image Stablization like Canon's modern lenses but that's just nitpicking. I love it as it is.
