Hello! I'm a professional photographer who has lived in Vietnam for 9 years. I'm back in Ottawa visiting family and am bringing my 300mm 2.8 back to sell. If you are looking for an insanely awesome lens to shoot sports or wildlife, take a long hard look at this particular lens. Its in excellent condition - I barely use it for what I shoot. for some reviews on the lens see: http://www.sigmaphoto.com/300mm-f28-ex-apo-dg-hsm Lens Review - Sigma 300/2.8 HSM EX SIGMA 300MM F2.8 APO EX DG HSM NIKON EX300DGN Sigma 300mm f/2.8 EX DG HSM Autofocus Lens for Nikon AF-D 195306 I think I am selling it at quite a reasonable price considering its market value. usd:2000 cad: 2600 Am willing to ship within north america.
