Do you need a 15mm VF for the CV 15 Heliar III

I have the optical finder for 15CV which I used only once with my M9. I simply shot by looking through RF finder and imagined the wider view. It was never a problem. Now with M240, I do the same. It is much faster. I only use LV for shooting from tripod. No EVF needed. IMHO, EVF is needed only for long lenses. YMMV.

Do you guys think that the 15mm CV lens can be use as a general photography lens to warrant the use of OVF?

21 mm is a field of view of around 90 degrees, I can ballpark that reasonably well.

Shorter focal length must be a lot harder to pre-visualize, 21 mm is the widest I go.
