Hi, I just started to use a C500. I couldn't adjust aperture with a third party lens (irix 15 2.4 blackstone), the f value does't show up on the left bottom of screen. I tried several Canon EF lenses, all worked, no aperture control issue.
Is it any chance I can make working that wide angle lens (otherwise I need to sell it)?
