Prepare to be bored ;)
Wildlife lens is a Sigma 150-500mm that I bought around 4 and a bit years ago with a redundancy payment. The lens itself is great, but the optical stabilisation packed in after a couple of years, and the autofocus went the same way. I sent it back, and it came back saying 'oh, it's your camera body'. But it's not, cos I've now tried it on a couple of bodies. I think the mount is a bit knackered, so it generally lives on my old Nikon D90, though I will occasionally put it on the newer D7100 (but I don't trust it not to break the camera).
So everything for the last few years is OS-less and manually focussed. I think, however, I'm going to send it for a service this week (cheaper than buying a new lens! It's out of warranty) so that (fingers crossed) they can get it working properly again for my annual pilgrimage to Skye in June. I'm loathe to do it, mainly because it means a few weeks without the big lens! I may see if I can pick up a reasonably priced 2x converter to use on my 200mm...
p.s. thanks fimm and jdanielp - as I say, not quite the shots I was after, but they're a long way away!
