 +===== Facts =====
 +  * an all-manual mirror lens (also known as reflex lens, catadioptric lens, CAT)
 +  * in addition to this there appears to be 500 mm f/5.6 and 1000 mm f/10 CATs available
 +  * estimated retail price 350 USD
 +  * in my use from 3/2006 to 10/2008
 +  * only for outdoor use on bright days and is still hard to focus
 +===== Pros =====
 +  * much cheaper, smaller and lighter than the equivalent focal length regular lenses
 +  * if you need a 500 mm lens and don't have much money there are no alternatives
 +  * ring-shaped bokeh can be fun
 +  * every photographer should try a mirror lens once
 +===== Cons =====
 +  * weak contrast
 +  * not very sharp
 +  * requires plenty of light to be usable and is still hard to focus (I recommend a body with a large bright viewfinder and installing manual focusing screen like Canon Ec-S)
 +  * fixed aperture (f/8)
 +  * ring-shaped bokeh can be annoying
