Digital photography

I have one. Have been very happy with it overall. I've used it in drizzle and it's been fine but only for relatively short periods.

If you can make it to Putney you're welcome to come try it out if you like.

Does anyone have experience with the sigma 70-200 f2.8 OS lens? http://m.dpreview.com/lensreviews/sigma_70-200_2p8_os_c16 . I'm on the verge of buying one to be used with a d7000. I'll also be buying either the Nikon or sigma 1.4x teleconverter. My only worry is the weather sealing. Most of its use will be wildlife in dark and humid/wet tropical rainforest (borneo & Cmbodia) . Does anyone have any thoughts/ experience? I can't afford the modern Nikon equivalent and although I could borrow a Nion 80-200 2.8, its about 10years old, a little fungussy and the focus is slow and noisy.t
