a much awaited telephoto zoom lens to replace the much maligned pump-action style 100-400mm 1998 era lens designed before dust on digital sensors was a problem
4x zoom and big and heavy weighing in at 1.64kg with the tripod mount and extends out to 19cm at 400mm focal length, and as such is best used on a pro-grade larger dSLR to give improved balance
well built and with very close focus, it should be a popular lens for wildlife and sports photographers
specs
100-400mm f/4.5-5.6 giving 160-640mm field of view when used on cropped sensor APS-C dSLRs

supposedly gives reasonably sharp hand held images at 400mm down to 1/15th sec
dust and moisture sealed but not watersealed
focus range limiter
macro to 1m giving 0.31x magnification (working distance 54cm at 100mm and 57cm at 400mm)
77mm filter
21 elements in 16 groups incl. 1 x flourite, 1 x Super ED

9 circular blades
zoom torque adjustment ring allowing you to set the zoom ring from “Smooth” to “Tight” to suit your particular way of shooting
large bayonet ET-83D lens hood with Olympus-style slot to allow rotating a polarising filter
marginally sharper across the frame than version I and a Canon 70-200mm f/2.8 with 2x TC III
does not zoom as far as version I and really only goes to 383mm focal length
will AF with 1.4x teleconverter but only with the centre AF point and only on some cameras such as 7D Mark II, 5D Mark III and the 1D series, but not on the 60D, 7D, 5D Mark II
