Well I recently acquired this 'Big' bad boy, in excellent condition but without a case or any caps or Hood. I started doing a little research and the serial number suggests that it was made by Sun Optical, and my copy was produced in 1983. I need to buy some caps and find or make a hood for it. it does have that proprietary interchangeable mount and I wish there was an adapter from that lens (bypassing their mount) directly to my GH2 without an MD to m43 adapter. My lens was in Minolta MD mount and I already had some extra mount caps for it, and I'm currently using a Coffie cup lid for the front (fits perfectly) until a cap arrives. I Need to get a case for it, does anyone have any suggestions? I don't want to spend too much or ill just build one out of cedarwood, wrap it in pleather and Line it with felt, filled with silica desiccants. Not sure what I will do for a Hood.
