Coverage of CV 25mm viewfinder

[pvdhaar]

My Voigtlander 25/4 Snapshot Skopar came with a separate 25mm finder, or so the print on the finder says.

But looking through it the brightlines cover not even a hair width more than the 28mm framelines on my camera (KonicaRF).

Does anyone else have a comparable experience? I know that projected frame lines aren't the most precise, but that the 25mm of the separate viewfinder gives the same coverage as the built in 28mm seems a bit odd to me..

peter,

just last nite i was reading some archived threads about this very thing, kinda spookky...just can't remember where. might have been the photo.net leica forum- under the ltm section.
anyway, i got the impression that there might not be that great a difference in the coverage.

Sounds like the Konica's 28mm framelines are exceedingly generous! I just put the 25mm and its external finder on my CLE and compared the internal 28mm framelines with the finder's... quite a lot different! But mine is the older VC 25 finder without bright framelines.

I recall people commenting that Leica made their framelines "stingy"... that is, covering less than the lens covers, in the M6 & later (don't recall about M4). Or at least less accurate in that direction than the M2/M3.

That seems a "conservative" move on Leica's part, so that the camera user will at least capture all that he saw in the viewfinder, though he may need to crop the neg. Perhaps fewer complaints that way than the opposite?

I wonder if Voigtlander made the bright frameline 25 finder cover less than the older finder, or if the Konica 28 framelines cover a very generous 28mm field, or both?

The angle of view of the 25mm lens is 82 degrees, versus 75 degrees for the 28mm.

Thanks for the reality check guys. It appears that the difference in lens coverage isn't all that big in real life, so I shouldn't need to worry too much..
