Well, the 80 sounds like the way to go then. I might jump the bullet on an APO in the future, but definitely not on my priority list for now. I just saw an APO-N lens on Tha Bay, darn, that has a perky price tag to it ($595) ;-) It's nice to have f4 for focusing although the lenses I've used so far are all f5,6. Thanks for the comments!
