I have been raving about this lens on this forum so I think a review would be fair.
* Build and design, metal and glass, not like those modern plastic things
* Great colors
* Fast AF (compared to other lenses this age)
* non-circular aperture
* Strenge bokeh wide open
* Small focus ring
This changed the way I do photography. I couldn't really see the value of primes when you get so much more with flexibility with zooms, but was I wrong. This is currently my favorite lens - sharp, great colors, focal length and weight makes this lens city lens of choice. The f1.7 makes this lens ideal to capture Paris by night.
