Hasselblad SWC Zeiss Corrector Lens Set

Recommended Posts

In another thread I started about strobes, the thread was getting sidetracked with questions about the SWC corrector lens set. So I decided to start a new thread. 

The Zeiss corrector lens set is used to correct for the decrease in angle of view due to the physics of water when using the SWC. The set consists of the outside flat port (spherical inside) and the smaller lens that mounts on the camera. Even if you have these two lenses, you also have to have the "gauge" tool to properly set the distance between camera and port and also to ensure that they the camera is perfectly perpendicular to the gauge tool. The camera is set at 10 feet, seated on the gauge tool, and mounted using the SWC mounting screw which allows for adjusting the axial distance. This "guage" tool is screwed in place of the port lens, then removed. My dad never acquired the SWC rear section of the housing. Instead, he removed the prism and would imagine the viewfinder frame. Haha.

Interesting, prices are not quite as savage as I might have thought.   Quite the procedure to install the lens and camera compared to today's options - have to be really dedicated to get the best use of this .

For sure, Chris. Definitely not a procedure to do while on a crammed dive boat.

Growing up, I was always fascinated by my dad's dive gear and cameras from the 60s. I used to dive in our pool whenever I could at 10 yo. I was certified at 14. On dive boats, that system would always draw a crowd. Lately my dad has been in the hospital following complications from hip surgery. He's 76 and can no longer dive. It was the activity we did most together. Many fond dive trips off Monetery and the Channel Islands. Shooting this system again is how I feel close to him. Every day dives I'll take my compact system, then take the Hasselblad on bigger trips off the coast, like the Channel Islands. I want to keep it going for as long as I can. Hopefully next year I'll be able to get the new digital back for them. Even if I get sick of it, I can still shoot the cameras on land. I'll only be out for the cost of servicing the housing. The strobes I will get for it can be used for an SLR.

BTW, which housing do you have?

I've got a Nauticam housing with an Olympus OM-D Em-1 MkII, I'm happy with it, seems like a sweet spot  in sensor and dome/housing size to me.  Some of the old equipment is very interesting though I'm not sure I would want to shoot film underwater.
