What is the difference between the Firefly model and the Blackstone Model? Which would be better with a Canon M-50 with the M to EF/EFS adapter? Can it also be used for landscape photography? Thank you for your time
The IRIX 15mm f/2.4 Firefly Lens for Canon EF has a Weather-Sealed ABS Plastic Housing; the Blackstone version has a Weather-Sealed Magnesium Alloy Housing. Either lens will work equally well for landscape photography.

Hi, I use this lens with a canon EOS RP and the EF adaptor. Why is the lens doesn't go down to 2.4, and get stuck at 2.5?
I have similar setup (EOS r) and see same but I do not find the lens is “stuck”. When canon reports it at f2.5, the lens is wide open. And IRIX rates this lens at f2.4 which is a mathematical result of focal length and aperture diameter. Canon reports f stop numbers in 1/3 increments (typical setup). 2.5 is 2/3 of stop between f2 and 2.8. This is same on all Canon EOS camera.
