35 lux asph with .58 frame lines

[Roma]

Hi all,
I have an M7 .72 finder with a 35lux asph and a 50lux pre-asph.
I used to use the lenses 50/50, but now use the 35 about 70% of the time.

I'm wondering if it's easier to compose with .58 finder and a 35lux asph since the frame lines are easier to see. It may help with seeing more of the frame since the lens will not block the view as much.

I don't have a place to get my hands on a .58 camera, so I'm curious about what you may have to say.

You may even know someone who will trade my .72 M7 for a .58 one if you think it's worth doing it.

If you like having space around the frameline, then the 0.58 works great with a 35. Although not exactly the same, it has a similar feel to using your 50 with a 0.72 finder. If you like the amount of space around the framelines when using your 50, then you will probably like using the 0.58 with your 35.

Really? 35 frame lines on .58 are like 50 lines on .72?
This probably means the 50 lines on .58 are waaay out there and it will be hard to focus with a 50 lux.
Anyone else?

I have no problem focusing and composing with my 35mm Summilux ASPH, on my .58 body. It is an excellent solution when one feels the need to see the entire frame at a glance. But the focusing accuracy with the .58 finder is more than enough for a 35mm f/1.4.

The 50mm frame on the .58 is not too small to work with; but like all 50mm framelines on cameras since the M4-P, it is undersize for the angle of view of a 50. It actually covers the same area as the 60mm Elmarit on my R5. So it is 20% undersize in width, and 20% undersize in height. To put it another way, the 50mm frameline only covers 80% in width and 80% in height, of what the film sees. Since 0.8 times 0.8 is 0.64, then the 50mm frameline covers only 64% of the area the film sees. Not good! I've taken to keeping the 50 on my M2 or M3.

All framelines are undersized to a degree, but most, including the 35mm, are close enough. It actually covers the same as the 40mm Summicron. That's still not accurate, but with a 35mm lens, the 35mm frameline covers 74% of the area the film sees. At least that's a little better, and arguably close enough for an RF.

All my observations were made at a medium distance of around 18 feet.

Summary: For us eyeglass wearers, the 35mm lens is very good on the .58 body.
