Increase the length of your Aquatica underwater housing's lens port via this 1.0" Port Extension Ring, in order to allow for the use of longer lenses or teleconverters. The ring is also designed to enable positioning of the front element of your lens as close as possible to the interior of the port, in order to minimize distortion for better image quality. See the Dimensions Chart to learn how to measure properly for an extension ring. This helpful accessory is compatible with all Aquatica DSLR camera housings.

A stainless steel locking mechanism ensures a secure connection between the ring and the lens port, while your camera housing's own locking mechanism connects the ring securely to the housing. The extension is crafted from a 6061 T6 aluminum alloy, which has been anodized for excellent resistance to corrosion. It features a depth rating of 295'.

Q: 9. Does this RFi Softbox work on a B1 or B2 head? Will it mount on an OCF speedring? Or, is there a dedicated OCF version of this size?

A: The 1x6 mounts on both the B1 and B2. With the B1 use a regular size rfi speedring, or any profoto octa ring. With the B2 you will need the Profoto ocf speedring because of the smaller diameter. If you use a non rfi speedring with the B1, make sure the octa ring has the extra holes to mount a strip bank. The rfi rings make it very easy because they are color coded.I hope this helps.

Q: 10. Do you also need a reverse ring along with this, or is it safe too assume it makes the lens hook up backwards since it is called a macro extension?

A: No, these tubes mount between the body and lens to allow for very close focus. Nothing else is needed.
