SLRgear Review October 1, 2012 by Andrew Alexander. In February 2011, Canon announced the next iteration in its super telephoto primes; the 500mm and 600mm ƒ/4 II lenses.
I gave the Canon EF 500mm f/4L IS II USM Prime Lens 3 stars (Instead of 1 star) because it was quite sharp and at f/4.0 was capable of decent pictures in low light. However, this is a $9000 super-telephoto Prime lens and it produced sharpness and focusing accuracy at best on par with that available from my Canon EF 100-400mm F/4.5-5.6L IS II
