Alan Gordon MkV 35mm vs super35mm

[Hendrikus De Vaan]

Hi guys,

 

Simple question, but, I have an Alan Gordon MkV directors viewfinder, which has the markings for standard 35mm - but the new MkVb seems to have changed this to super 35mm.

 

Is there actually any difference in FOV between the two? I shoot primarily super 35mm sized digital sensors - in which case the sensor size differs slightly from camera to camera anyway, but it would be good to know if this is something I need to be taking into account.

 

Many thanks!

Super-35 is slightly bigger, 24mm wide instead of 22mm wide. You could just figure out a formula for adjusting the focal length markings to compensate. Since a director's finder isn't a lens finder where you put the actual shooting lens onto the finder, I think of it as just a ballpark idea of the framing anyway.

Thanks David!

 

So if I'm not mistaken, that's roughly 9% difference or thereabouts. So a 50mm becomes 55mm and so on right?

 

In that case, like you say - since it's a directors finder - it's probably fine just to read it as is.

Yes, a 50mm is more like a 54mm, or conversely a 50mm on the Super-35 camera would be closer to a 46mm mark on the regular-35 finder.

Ok, I was calculating in the wrong direction. That's what I get for trying to do math at 1am.

 

Thanks again for the help, much appreciated.
