see our BWP 67mm macro lens with a 77-67 step down ring as an alternative.
Dyron's 77mm macro lens (DY.UCL77) is coated to resist reflection and UV light. The 77mm macro lens comes with a 77-67mm step down ring that attaches to a 67mm or 77mm female threaded port. The larger lens diameter helps prevent vignetting if two of these lenses are stacked.
This lens looks like a single piece of glass, but it actually consists of two internal elements to reduce chromatic aberrations.

Superb lens. Delivering good results with my new Sony RC100 in my excellent new Nauticam Housing. Use a 67mm Lens Caddy and can easily change between this lens and my Bluewater WA-110 Wide Angle Lens during the dive.
Bluewater staff were extremely helpful with the selection of these lenses and housing.
The lens is just what I was looking for. I am using it with a Canon G12 in a Recsea housing and am enjoying experimenting with it. I only wish it came with a lens cover and a "pouch" for protection and quick storage when underwater. The staff at Bluewater was very helpful in their recommendation of this lens.
This lens is really good for macro and supermacro photography. I use it with micro 4/3 system, with the reduction ring, it mounts nicely to the 67mm female mount on the housing. It's easy to use underwater (but be careful not to lose it), so it gives you a lot of flexibility even on one dive.
There's still a little bit of chromatic aberration at the fringes of the photos, but I find is a nice "feature" in the final photography. Focusing with Olympus E-PL3 is fast enough and the magnification itself is really stunning and great fun.
I originally had the Woody’s wet diopter and liked it a lot, but I like the Dyron +7 even more as it is a better quality lens. I use it with my 60mm and occasionally with my 105mm on my Subal housing. It’s very easy to use with the 60mm, but takes a bit more skill and patience when using the 105mm because of the small focus range.
I keep the adapter on my Subal flat port and screw the +7 diopter on and off keeping the diopter in a pouch when not in use. The pouch is attached to my bcd and helps to keep the diopter from getting lost or scratched. I added the pouch technique after losing one +7 diopter on a dive with a lot of strong current. The two downsides to this technique is that the threads are very small and fine, and one must be very careful not to get the diopter cross-threaded onto the adapter. The other is that the diopter has scratched the glass on my flat port, but it’s outside the field of view of my lenses, so no big deal.
Bottom line - If I lose this diopter, I’ll buy another +7!
I have the Dryon +7 dioptre and the M77 adapter for an Ikelite housing. I found this dioptre easier to use with my 100mm macro lens initially, but recently I have been using it more with my 60mm macro.
Pros: Excellent system for more magnification and super macro. Easy to put on and remove the dioptre underwater. The 60mm macro and Dryon adapter (in particular) give a very versatile combination (being able to switch from super macro and macro/mid range shots on a single dive) and an excellent combination for travel.
Cons: Small amount of chromatic aberration at the fringes of the photograph and not very sharp at the edges for high apertures (f20+, I rarely shoot supermacro with these settings and I want bokeh anyway); however I think this is a small price to pay for the versatility of the system and realistically any system (wet or dry) will have the same problems. Focus can hunt, so you need calm conditions to use the dioptre - very difficult to focus in surge.
I am very happy with the results from this dioptre.
I bought this lens to do more than 1:1 macro photography. I get about 1.3:1 with a 60mm and 1.7:1 with a 105mm using a Nikon DX sensor. It is a little frustrating to use at first as it doesn't focus to infinity but once you get the hang of it, it's great. The IQ is great. The lens is small and light and I put it in my pocket when I'm not using it. It's a ton of fun and brings a whole new dimension to macro photography. I highly recommend it to anyone interested in supermacro.
