200d Aperture Stops

[brenski]

Is there any way to adjust the F stops scale from thirds to halves?
I've just bought an Irix 14mm F/2.4 -
I'd like to have the Aperture scale match that of the lens - ie start at 2.4 rather than 2.5

Hi Alan
I already have CFn set to half stops, but it scale still starts at F/2.5 (which is the 1/3 scale).
No amount of changing the setting in CFn from 1/3 to 1/2 and back...and back again - makes any difference, the scale still starts @ F/2.5

i don't think this is a 200d firmware issue? my firmware was 1.0.1 i've now updated to 1.1.0 - still no change. F/2.5 is the widest camera setting. I'm assuming now this is as Irix claim: the Camera software doesn't display the correct setting for the Firefly - even though the Firefly is open at F/2.4 ?

found this in an online Extended User Manual

"When selecting the maximum aperture of f/2.4, some camera models will display f/2.5. This is a software issue with some systems. The actual aperture size will be f/2.4."

this would imply that - Camera Menu issues aside, there's a comms issue in play also.
