My mistake please disregard. Lens works fine Re: New Laowa 14mm f4 for Canon ef mc-21 adapter

Please disregard.  The camera was set to auto-iso so the aperture appeared to not be changing when watch the histogram.

Title says it all. I'll be testing it at f4 and also on my SD1 and sdQuattro to verify the aperture changes on a true ef mount but if you were thinking of it for an L mount via the mc-21 I'd say hold off until Laowa fixes this or until I find out it is a problem only on my lens.
