Kyle,
where is a good source for used lens? I would love to pick up a used 85mm/1.8! I have a heck of a time with the gymnastics shots and that one would be fast enough to stop her in mid flight! I tend to walk the perimeter of the meet area anyway - just can't stand sitting for that long!

Thanks for your help!
Blessings,
keh.com is great. Excellent reputation and more than very fair with their ratings and prices.
For non DX lenses you want to find the Nikon Auto Focus under 35MM (for Canon, choose Canon Auto Focus in the same area). Then then in the box below choose Fixed Focal Length for all Nikon lenses (or Canon if thats what you have). Obviously choose Non-Mfg Fixed Focal Length for Sigma, Tamron and other makers.
Right now they have a Nikon 85mm 1.8 new at $399 and a used one for $339.
They also have a bunch of Tamron 90mm f/2.8's in a Nikon mount for between $325 and $399 depending on its grade and when it was manufactured. Also a few Sigma 105mm f/2.8's for $310-344.
For Canon they have a new 85mm f/1.8 for $314.
A used Canon 100 f/2 for $349. The Tamron 90mm f/2.8 in a Canon mount used for $250 and a Sigma 105mm f/2.8 from $265-325.
This stuff doesn't last long, but they do get items in all the time.
That probably more info than I should include, so if Jeff's see fit, he can remove it or ask me to.
