Is there any C-mount adapters that mount the lens right-side-up? (UPDATED!) I just received my Fotga C-mount adapter, and found out it mounts the lens up-side-down. Is there any quality C-mount adapter that mounts the lens properly? I'm currently using a Pentax 25mm 1.4 and I have a Cosmicar 75mm 1.4 arriving soon as well. Should be fun. Has anyone tried this Yeenon adapter which lets you adjust the mid-point: ã€Yeenonã€‘ C Mount to Micro 4/3 Mount adapter (can adjust the midline position) | eBay UPDATED! I was able to adjust my C-mount lenses by adjusting the screws on the mount. Here's quick picture: They're super small, so I had to use an exacto to loosen them. But after adjusting, my c-mount lenses are all in the proper mid-point orientation!
