Want to trade Nikon AFS VR 105mm f2.8 for Canon EF 100mm f/2.8L Macro IS USM

Have just made the jump from Nikon and bought a Canon 5D Mark iii. Looking to trade my Nikon Macro for Canon as above.

My Nikon 105mm AFS VR f2.8 is approx 20 months old and only used for diving. To date it has done around 40 dives.

Cheers

Scott

I have a canon 100mm macro but am not looking for trades. Its basically brand new. 500$

Is it the model mentioned above?

I doubt it is an L at that price. It is probably the EF, USM. Its still good glass. I have an L for sale here on Wetpixel but I also do not want a trade just a sale. $775ish

Sorry, he's right, non-L version

Thanks for the replies, looks like i will have to sell the Nikor 105mm first then look for a Canon 100mm
