Left to right: Tamron 180mm f/3.5 Macro Autofocus Lens (Canon EOS mount), Canon Macro Photo MP-E 65mm f/2.8 1-5x Manual Focus Lens, Canon EF 100mm f/2.8 USM Macro Autofocus Lens, Tamron 90mm f/2.8 SP AF Di Macro Lens for Nikon AF, Vivitar Series 1 105mm for Nikon and an Olympus Zuiko 50mm macro lens.
Over the years my macro equipment has transitioned from the era of film to the digital present, and in that time I have accumulated a few macro lenses. The picture above shows most of them: missing is an Olympus-mount Tamron SP 90mm macro lenses that provided only half-life size 1:2 mag.
All the above lenses give 1:1 (life-size) magnification. Why so many sizes if they all produce the same magnification? What are the benefits or handicaps of each?
