Comments about Canon Canon MP-E 65mm f/2.8 1-5x Macro Photo Manual Focus Telephoto Lens - Grey Market:

This really is a unique macro lens; the only on the market that can magnify up to 5x. Most lenses capture what you can see, this captures what the naked eye can not. The lens is of extreme high quality producing sharp images in the mode of the professional 'L' class lenses. This is a great product for those of you who need to go beyond 1:1. The only downsides are that the working space at 5x is very small and so can not be used for rapidly moving bugs (I would love a MPE-300!) and that the f-stop changes with increasing magnification; at 5x F/16 is very soft. As this lens does magnify so strongly, I solid tripod is needed. I use an Manfrotto with a 410 geared head with an [...] bidirectional rail - not a cheap set up, but very useful for the very fine adjustments required.
