In My experience the Canon EF501.8 while holding the crown for cheapest Fast 50 ever! is not my or my canon owning friends favourite by a large margin. We can all accept plastic and cheap grinding focusing mechanism but optically it does not get near as sharp or contrasty as its 1.4 big brother until F5.6 2.8 is livable but still a compromise. so Looking good on paper is wher it must remain im afraid. The Nikon Af351.8 fares much better and is the real competitor however it actually reports as F2.2 and even DP review says it needs to be stopped down a bit. So here;s hoping Pentax can beat it optically! I bet they can...
Cheers
