Canon EF 28mm f/2.8 USM IS - APS-C Format Review / Lab Test

Canon EF 28mm f/2.8 USM IS - APS-C Format Review / Lab Test | Photography Gear News | Scoop.it

The (old) Canon EF 28mm f/2.8 is a relic of the earliest days of EOS. This year it celebrated its 25th(!) year in production which is nothing short of amazing for an AF lens. However, 2012 is finally also the year of its successor - the Canon EF 28mm f/2.8 USM IS. As you may notice the focal length and speed remained the same but Canon added a modern USM (Ultrasonic) AF as well as an image stabilizer. While USM is not really a killer argument (the micro-motor AF drive was fast enough after all), the IS certainly widens its usage scope specifically with respect to low light photography. Used on APS-C DSLRs the field-of-view is equivalent to a 45mm full format lens so it's more like a standard/normal lens here rather a wide-angle one. Something like street photography would be an obvious application.
