...A Canon 90-300mm f4.5-5.6 autofocus zoom - for a tenner. Works well on the old 35mm Eos body I use for testing lenses, and it's stopping down and focusing as it should and seems to be a very nice clean lens. I've got a rear cap for it and found a rubber hood that fits, no cap but what I'll probably do is buy one before I list it on eBay - for various reasons I won't be doing so for a few days. A bit old, and I'd imagine designed for 35mm cameras, but still ought to be a nice little earner. Oddly, this is from the same charity shop that sold me the weird Sigma lens for Canon last year, it's the only other time they've had any photographic equipment I can remember. Pleased anyway.
