So as I understand it, you need to stop the lens down manually before taking an exposure? Will this be the same on Nikon cameras, or is this specific to Canons (because they don't have a mechanical aperture lever)?

 

On more request - if you take sample images, please shoot into the setting or rising sun a bit, I would be interested to see how flare-prone this lens is.

 

Thanks for the test!
