Canon EF 135mm f/2.0L lens
- one of my favorite Canon lenses
- introduced in 1996
- on my 1.3x crop Canon 1D Mark III digital SLR it gives an even longer effective focal length (176mm) but I love it for 3/4 length fashion shots when you want to blur the background and you have 3m or so to spare from camera to subject, but it also works very well as a portrait lens with its shallow depth of field (DOF) and lovely bokeh
- it is very susceptible to flare so using the big lens hood is almost mandatory in any light!
- sharpness improves as you stop down so by f/4 the 5D sensor resolution is limiting sharpness, no longer the lens.
- a great portrait lens, especially for indoor performance photography but too long for the cropped sensors for indoor portraits
- it can be used via adapter on an Olympus OM-D E-M5 camera to give an effective 270mm f/2.0 image stabilised manual focus lens (yes I know the DOF is more like a 270mm f/4 lens but when shooting at 270mm focal length you don't generally want shallower DOF than f/4)
- $A1879; 750g; 72mm filter;
- NOT weather sealed!
- min. focus 0.9m ⇒ 0.19x magnification on full frame
- USM rear focusing AF with full-time MF
- focus limiter switch - full range or just 1.6m to infinity
- 10 Elements in 8 Groups, two UD elements, internal floating design
- designed to be used with EF extenders - 1.4x or 2x with “minimal” loss of image quality
- at 3m focus distance, at f2.0, depth of field (DOF) is still only ~6cm on a full frame camera
- supplied with ET-78 II bayonet lens hood which is indispensible with this lens
- similar resolving power as the Canon 70-200mm f/2.8L see here
- has more CA than the 200mm f/2.8L II, and CA is worse with tele-extenders
- at f/2-4 it is sharper than the 100mm f/2 or the 85mm f/1.8, with more micro-contrast on full frame sensors, and has better background blurring for the same subject size
- for astro work see:
- http://www.astrovalerio.altervista.org/canon-ef-l-135mm-usm/index.html - best moon detail shots are when used with 2x plus 1.4x teleextenders (ie. 378mm f.l.) and stopped down 1-2 stops.
- as sharp as the Canon lens is, it is not as sharp as the Zeiss, particularly across the frame at f/4 or wider, however, the Zeiss lens is only manual focus and is twice the price
