Canon 50mm 1.4 vs 1.8
Mike,
Main difference is in build quality/weight - ie plastic mount (1.8) 130g vs metal mount (1.4) 290g and the faster, quieter USM autofocus with manual override full time on the 1.4. There is a 5 blade diaphragm on the 1.8 but 8 blades on the 1.4.
Having said it is not for astro you might find those differences significant...if it was for astro I would get (well have got in fact :-)) a Zeiss or SMC Pentax plus adapter...
