Selling my D300 and housing plus a lot of accessories as I switched to a mirrorless setup and have not been using this. The housing was sent to Ikelite for service and they actually replaced the main housing because of a small crack and the electronics, so everything related to the housing is new or like new.
You will notice some tape around the circumference of the lens - this is to hold a piece of plastic the mates with the zoom gear for the housing and there is nothing functionally wrong with the lens.
Included in this sale is the following:
Nikon D300 camera (with original box, manuals, body cap, strap, cables)
Sigma 10-20 DC HSM lens
Ikelite housing for D300
Tray and handles for D300 housing
Sync cord for single strobe
wide angle port
8" dome with neoprene cover
Guide to the D300 by Thom Hogan
4 CF cards to 32 GB with waterproof case
Asking $2350 for everything or would consider breaking up and selling individual items.
