I'm selling a lot of Raynox adapter tubes for digital cameras with retractable lenses - the tube screws into the lens surround so that you can add filters, converters, etc. They include a couple for Canon models: for Canon LA-DC58C - 1 only http://www.ebay.co.uk/itm/132353962751 for Canon Powershot G1/G2 - 5 available http://www.ebay.co.uk/itm/132354014751 Lots of others for other brands, see my other listings for details. They're ex-shop bankrupt stock, unused but very battered boxes. I'm nominally selling them at £2.99 each plus postage, which will be £2.90 in the UK (most of them are more than 1" thick in all dimensions so have to be sent at parcel rates - the exception is the LA-DC68C ring which will be sent at large letter rate, £0.98, if it's on its own) and more overseas, but I am VERY open to offers on this one, since I have about 70 to shift. Since they don't weigh much postage for several shouldn't be very expensive - e.g., in the UK I could send about 25 or 30 for that £2.90, prices for other countries start to rise for multiples of four-ish - but get a quote since it's difficult to set postal prices exactly when each type has slightly different weight.
Forgot to say, I've pulled the remaining adapters from sale until the new year because I want to take a week or so off, I'll re-list them on January 2nd.
