The EV system is fine with me, it’s just the way it was implemented on the Ikoflex meter that confuses things. I may be one of the few people who actually like the coupled shutter/aperture setup. I had it on my Ikoflex and a Retina Ib, at one time my only cameras (not including an Argus C3 Matchmatic, speaking of arbitrary metering systems) and I learned to like it. Beyond the EV system, it’s great for Sunny 16. Like this: Afternoon direct sunlight and FP4 get me 1/125 at f8. Click click click 1/125 @ f8. But I want to isolate the subject better… scroll scroll scroll to f3.5 @ 1/Whatever because it’s already set. Really slick.
However, between the financial schemes of light meter manufacturers vs. the tendency of the general public to reject math in any form, I think it was just too thinky for old Uncle Dave on his Hawaiian vacation. EV was a step towards auto exposure, then autofocus, then digital compacts, then iPhones. Some form of it is still at work behind every modern camera, minus the thinking.
Anyhow, Ikoflex = excellent images. Took mine out today to admire it. And it is admirable.
