  • Fast. Very fast. But it was fast even at ist D

  • Its an excellent sharp lens for a very good price!

  • Screw mount lenses are loud, but still really fast focusing.

  • @mikeismad61 This is already i pretty old lens i think

  • Sounds like my 30 year old Canon 50 1.8 AF. Think Pentax have some chasing up to do!
