Thanks very much for the feedback, gents.
Heywood - as Harrogate says, that's my current equipment list. To be more specific, if you right click on the images and view the properties, those starting with IMG_0 were taken with the Canon EOS-20D and Sigma 120-300mm f2.8 lens, while those starting IMG_4 were taken with the Canon EOS-30D and Canon 400mm f5.6 lens.
Nozzlefaff - check your PMs.
Bob - check your email.
Thanks very much all.
