I had SK Grimes manufacture an adapter from Series-size thread to 37mm thread so that I can put a 0.5X wide angle adapter on my 5.5mm Bolex H8 Rex lens.

As you may know in the Bolex 16mm line they made a wide angle adapter for the 10mm lens, but as far as I can tell they never made a wide angle adapter for the 5.5mm lens for the H8 cameras.

Bolex Aspheron converter for comparison (10mm to 5.5mm for 16mm cameras):


This works great. It provides full frame coverage.

No, for a number of reasons. I don't think my 5.5mm will cover. I know it won't cover with the 0.5X converter. I don't think my fancy EE 8-36 Switar Zoom will cover either. Also, There were more choices in regular 8 B&W in the last 15 year or so (well three, Cine-x, Super Cine-x and Foma). Howerver, looks like its going to be down to Foma as the only B&W regular 8 and DS8 now also.

SK Grimes also made a threaded adapter for my 8-36mm Switar EE zoom from Series-size threads to 49mm so I could mount a wide angle adapter on that zoom. My film gate is just under 8mm in diagonal, so the adapter makes it into a real Wide to Long zoom.

Ic, I don't recall where I read it -- possibly The Super8 Book -- but I understand that a fairly simple machining operation will allow the 5.5/1.8 Switar in H8Rx mount to cover S8. Your zoom should cover S8. I went S8 back when because of the larger image, would have gone 9.5 if I'd had faith in the availability of stock.

This is the missing picture of the 5.5mm lens, SKGrimes adapter and 0.5x converter.
