I remember a paragraph in a book teaching photpgraphy by Alexander Spoerl, which was very common in the last '60s - early '70s, in which the author introduced the matter of these cameras with EV scales and concluded that yet another confusing scale has been added, which will further confuse customers already quite puzzled by the shutter and aperture scales.
I think however that the picture above clearly illustrates that the end result was just a further scale added to all others, which is exactly what mr. Spoerl complained about.
None of my camera has EV scale but the EV allows me to figure out equivalent exposure in my head.
People accepted flash Guide Numbers too. Something that follows the same idea.
I use the EV a lot to figure out the equivalent exposure but not the guide number. I would convert an exposure in aperture, shutter speed and ISO to LV and then convert back to another setting that gives the same exposure. I can do this in my head and in 1/3 stop intevals. However when I used manual flash I just guess at the setting rather than use guide number. After using some flashes for a while I got the feel of what aperture and manual power setting on the flash to use even in case of bounce flash.Guide numbers do kind of sort of make sense, aside from the fact that the math gets a bit weird when you're adjusting for different sensitivities. Also, they go to heck with anything other than direct, unmodified flash which no sane person should be using.
Still, though, for the occasion I use bulbs on a Nikon F or F2(usually the F because its flash sync settings are a lot more flexible with respect to using both M and FP type bulbs) the 45mm f/2.8 GN is a life saver. Of course, that's still not straight forward as with an FP bulb like a GE #6 the GN changes according to the shutter speed...
The system works in a clunky way with the C lenses and their ergonomics.
The beginning of the end for EV was when Hasselblad unlinked the EV on their CF lenses. What a dumb idea. EV and the EV-lock shutters are a major convenience!I have a couple of old cameras that uses the EV scale. I even set my digital Sekonic meter to display EV for those old cameras. My question is why did camera manufacturers got rid of EV?

My guess is that there was no point to EV once automatic exposure metering came in. You set the aperture and the camera sets the shutter speed. EV is of no use to that camera.
Yes. I started using manual SLR cameras since the 80's. I first started getting experience with EV cameras 30 years later. I was even a photo assistant and later a professional and never came across EV until my wife gave me his dad's old Zeiss Super Ikonta IV. Once the EV was set, I could set the F stop and the shutter speeds followed. The meter displayed only in EV. I thought it was brilliant. I got a used Hassy and it worked with the same system. I like it so much that I reset my modern digital Sekonic display EV. Too bad they got rid of the system. I think if I were a photo student back in the 80's that had a camera with the EV system, I would have learned shutter speeds and Fstops faster being learning disabled. The system is brilliant.EVs are great if you have a camera and a meter and they both work/have scales in EVs.

Depend on how you work. If you first determine the light level of your subject whether by using the built in meter, hand held meter or using a chart. The EV helps in choosing the combination of aperture, shutter speed and ISO to use.
