The Ultrasonic (USM) Version)
* picture: Canon EF 35-80mm F/4-5.6 USM
Featuring the same body construction and identical exterior as the Mark III version, the only difference is this version uses the Ultrasonic Motor (USM) for focusing rather than the Micro Motor for the other 3 versions (Mark I, II & III). Even the lens grouping are the same! So you must thinking, what’s Canon trying to do back then? Having the USM made this version the Premium Kit Lens? Well, at that time (1990s), the first generation USM are earth shattering news. So indeed, the USM are marketed as a "premium" kit lenses and have it packaged it with mid range EOS SLRs like the EOS 1000FN (Today’s XXD range) and so on while the Mark I, II & III versions are packaged as entry-level SLR kit lenses.
Tested it for IR, gotten the same result with the Mark II version (expected) which I reviewed a while ago. Except for the USM, everything is the same. Really.
(If you are looking for the specs, please google yourself, it’s all over the internet.)
