Hi, I'm new to this forum but I thought someone might be able to point me in the right direction. I want to rearrange my gear(lighten the load) and it requires selling some lenses. How do I find out what a fair price is for the larger telephotos(EF600mmF4 & EF500mmF4.5)? The retail price is now less than we paid for them and they have IS, but I can't find any used comparable ones on the market to get an idea. The only other options are to send them into one of the companies used department which would be a low price. I have someone interested in one of the lenses but don't honestly know what to ask.
I have looked at ebay and the used listings but there aren't many used ones out there.Thanks in advance. John
