The Canon EF 70-200mm f/4.0 L USM Lens is probably Canon's best value "L" Lens, combining professional grade build and optical qualities.
Though solidly built, the Canon EF 70-200mm f/4.0 L USM Lens is relatively light (25 oz / 705g). Actually it is very light and small compared to the much more substantial Canon EF 70-200 f/2.8 L Lens or the Canon EF 70-200mm f/2.8 L IS II USM Lens. This lens is not a burden to carry for long periods of time but has a high quality, solid feel like all L lenses.
At 3" (76mm) in diameter, the 70-200 f/4 is relatively narrow for its 6.8" (172mm) length. I more frequently use larger diameter lenses, so this is one of the 70-200 f/4's instantly recognized features for me personally. It is not a bad thing - just different. I'm sure those with smal l hands appreciate this feature.
Results from the Canon EF 70-200mm f/4.0 L USM Lens will make you smile when reviewing at 100% on a monitor. This lens is very sharp wide open and improves only slightly when stopped down - and primarily in the corners at the wide end of the focal length range. Very slight barrel distortion is noticeable at 70mm on a Full Frame body. Distortion disappears by around 100mm and is insignificant on a 1.3x or 1.6x FOVCF body. Vignetting is very well controlled - full frame users might notice slight vignetting in the corners at f/4. CA is very well controlled.
Images from the Canon EF 70-200mm f/4.0 L USM Lens have great color and bokeh. The 8-blade aperture opens to a constant f/4 at all focal length ranges. This is a very nice feature as exposure settings do not require a change as the lens is zoomed through the focal lengths. F/4 is not fast and is not slow. F/4 is narrow enough to allow the smaller lens size and weight. F/4 is wide enough to create some background diffusion in this focal length range. F/4 is wide enough to not require bright light for handholding. However, I do not consider this a low light lens. You will likely need a flash when shooting indoors after the sun sets.
The Canon EF 70-200mm f/4.0 L USM Lens focuses very fast, very quietly and very accurately thanks to Canon's excellent Ring USM (Ultrasonic Motor). FTM (Full Time Manual) focusing is enabled. The focus and zoom rings are very nicely sized and turn very smoothly. The 70-200 f/4 does not extend with zooming or focusing - and the front element does not rotate.
The Canon EF 70-200mm f/2.8 L IS II USM Lens is a GREAT upgrade from the 70-200 f/4 L, but only if you need f/2.8 (lets twice as much light in) and/or IS - or weather sealing (the 70-200 f/4 is not weather sealed). You will not find the IS version's image quality to be much better - Full frame corner sharpness is better on the IS lens until the end of the focal length range where they equal out. The f/4 version performs better than the IS lens with Canon Extenders when used at the 200mm setting until both are stopped down to f/8 or so. An f/2.8 aperture will create a more diffuse background blur. The IS version carries significantly more weight and costs much more than the smaller f/4 version.
If you do not need your 70-200mm lens to be faster than f/4 and don't need IS, the Canon EF 70-200mm f/4.0 L USM Lens is your lens. The 70-200 f/4 L is a great value and a highly recommended lens. Read full review
