I never denied that extreme little coverage. But as I indicated you chose a figure that even makes it looks worse to SLRs where their coverage is calculated differently.
the two ways to calculate VF coverage have always been used. Manufacturers use the % of one dimension (width or diagonal) rather than the surface, because of course it's always a higher figure.
The axis % is also more intuitive because it tells the proportion staying outside the VF (left, right. top bottom), we evaluate things inside a frame by axial dimensions. So on most Zenit ~1/4 of the captured scene is outside the VF, half of this (~12%) to the left, half to the right, or bottom/top if you capture standing subjects and if the subject is centered.
I never had a problem with this, tricky cases are with full aperture and focus on an area which is at an edge, but it is uncommon. Most common are subjects filling the whole 24x36 frame edge to edge, no possibility to step back more, so in case I have the Zenit-V I must mentally compute the ~12% missing on each side. Can be tricky, I use to be conservative so works most of the times, but otherwise yes it's annoying for many people.
for instance the other day I went to take some pictures with a Start and one of its native Helios-44, and in these two the blue lines show what I was actually seeing in the VF. In the first I wanted to get the whole gable inside the nave and the surrounding edges of the entrance. In the other I wanted the full bridge with both cable anchors in front, and the whole fence and lights to the right. The whole barely fills the frame, but i took the shot seeing what is inside the blue lines. Now that's easy to figure but if I have had the Zenit-V. i would have had to figure out the distance from the red lines, which can be hit and miss.
