Sea and Sea Wide Angle Conversion Lens 20mm F5.6 U/W
starting at £49.99 
Lens has been a used on a few weeks worth of holidays and has been lovingly looked after. NO scratches on the lens. The lens front and back covers look used. Includes Sea and Sea bag and I am also putting in an adaptor that was bought for a Canon Powershot underwater housing - it was specially adapted by a company in the US. The lens was originally bought to go with a Sony MPKP9 housing (and had an adaptor which I previously sold). We also had a Canon Powershot and so arranged for this adaptor to be specially machined in the US to go with the underwater housing. I sold the camera set a couple of years ago on e bay - I have searched the archive and it was a Powershot S70 with a WP-DC40 housing. When the lens is used with this adaptor the photo needs to be cropped as you get a black outer ring from the adaptor. To be honest I am selling the lens and am putting in the adaptor in in case the buyer has a use for it. Only selling this lens as my camera has been replaced and there is no suitable adaptor for my new one so I can't use it any more
