| Introduction | Measurement | Comparison | Conclusion |
16 years on from its launch the 135mm f/2L USM is still a solid option for portrait, sport and low-light photography. That said as lens development continues to evolve recent telephoto primes like the Sigma 85mm f/1.4 EX DG HSM and Canon 300mm f/2.8L IS II USM do demonstrate notable improvements in Sharpness. Although performing well in all our DxOMark Lens Metric Scores the Canon EF 135mm f/2L USM only ranks 5th for EF mount telephoto primes on the EOS 5D Mark II and new in terms of quality to price ratio the Sigma 85mm f/1.4 EX DG HSM is noticeably sharper and a couple of hundred pounds cheaper. If you can pick up a Canon EF 135mm f/2L for a good price second-hand however then this very capable telephoto prime lens could be a bit of a bargain.

Sigma??? REALLY????
Well one thing is for sure. I ain't changing my 135/2L for no sigma anytime soon.. I'd marry my 135L if only I could find a ring that fits it :D.

Canon 135L
"... the Sigma 85mm f/1.4 EX DG HSM is noticeably sharper." (than the 135L)
This just shows how meaningless your new metric is. Your own measurements do not show any noticeable difference. There is almost none here: http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=108&Camera=453&Sample=0&FLI=0&API=0&LensComp=756&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=2 Also, comparing 85 and 135mm can be tricky. For the same background blur, you need f/1.4 at 85mm vs. f/2 at 135mm (same physical aperture). The 135L is then really sharper, much less PF/LoCA. BTW, nobody buys the 135L for sharpness - not that it is not sharp. It has gorgeous bokeh. Your "second hand" recommendation is really stupid. Reply | Read all replies for this comment |

Re: Canon 135L
Sharpness has nothing ado with depth of field....
And even wide open, or at least at f2 central sharpness on the Sigma is quite impressive. So yes the sigma is sharper than the 135L. It is funny though how people complain about the irrelevance of a sharpness test, while they are actually complaining that their lens is better... Both are telephoto portrait lens, so that's why DxO compare them. Sharpness is not the most relevant factor for portraits, that's a given, but DxO does not pretend to test usability or practicality of a lens. DxOMark tests resolving power, vignetting, light transmission and so on. A kind of pure image quality test, be it relevant or not to the application. If you want field tests and reviews, there are plenty of sources such as SLRGear, DPReview, photozone.de... and so on. DxOMark is just a metric... Reply |

Re: Canon 135L
You missed my point. DXO does not just report data, it makes a conclusion about the value of the lens overall. Then bokeh, f-stop vs. FL, etc., are primary factors.
