[Konvas] SLR lenses vs. Lomo Anamorphics

[Kelley Cross]

Hello all,

I bought an older Isco Director's finder on ebay a while back and was disappointed to find that the wide 35mm lomo anamorphic does not fall into focal lengths covered. So an idea occurred to me. Why not take my trusty Nikon f2 to the locations before the shoot, snap off some shots to the correlated focal lengths and process the same for the shoot proper (i.e. pulling in the lab, etc.)

All things being unequal, wouldn't it hold true that:

Correlated field of view should match anamorphic to academy, (i.e. 35mm anamorphic horizontal = 62.7 degrees = +- 17mm academy) In other words, an SLR lens approaching 17mm should yield approximate horizontal field of view for 35mm anamorphic. Put another way, just basically cutting the focal length in half. Is my math off here?

Also, am I nuts thinking that a shot with the Nikon at 5.6 compensating speed for 24 fps will yield the same exposure for the lomo at the same f-stop?

I realize that vertical correlation is a different matter, but there are a few older nikkor 18-55mm zoom lenses floating around that could make a nice inexpensive director's finder covering the 35, 50 and 75 primes. 

Best,
