While the release of the new EOS 7D is the big headline today, quietly released alongside the 7D is the new EF 100mm f/2.8L Macro IS lens - A powerful new piece of glass for macro photography & portraiture. This is also the first lens to feature Canon's Hybrid IS, which we covered a couple months ago when the technology was first announced.
As it is a true 1:1 macro lens, the Canon EF 100mm f/2.8L USM Macro IS will deliver a subject to your sensor at the same size it is in real life. 1x magnification is achieved at the Minimum Focus Distance of 1'. It doesn't take a very big subject to completely fill the frame at this 1x magnification.
If you're the type to be interested in such things, the MTF Chart for this lens is, pardon my hyperbole, INSANE. In a nutshell, what you're looking at is the lens' sharpness (along the y axis) from center (left side of the x axis), towards the corners (right side of the x axis), measured at various apertures.
If that chart is too much for you, and I totally understand that it could be, just take it that this lens is SHARP.... Make that SHARP and IN STOCK.
