Hello,

I was wondering If anyone here had used a Super 35mm gate on their Konvas 2M?
I'm about to order a gate from Bruce McNaughton. Are there any optical considerations. Aside from needing new 1:85 ground glass? Any experience of this?

Cheers

Is that Bruce from Aranda?
My understanding is that the Konvas can't cover Super35 without modification to the camera (not just a new gate!) Check with Bruce tho as he will know all about it as he has a lot of experience with the insides! It might be that it can cover part of the S35 area.

Dear Phil.

No, nothing else required other than masking your ground glass for 1.85:1.. The gate is not extended, only opened up vertically.

I had my Konvas 1M (upgraded to PL mt before I bought it) changed to Super 35.

Since I could not find the S35 gate anywhere I found a local machinist to cut a Konvas Anamorphic gate wider. He said it destroyed 6 diamond drill bits and said he'd never do it again!

I had Bernie at Super16inc recenter the PL mount, and he recentered the ground glass. He also added a wedge shaped piece of metal, covering the back side of the pulldown claw as a light baffle. I guess opening up the camera aperture lets light bounce off the pulldown claw. The light baffle causes slight squeak to the sound sometimes, but the camera was already really noisy.

Still waiting for the first test film to return.

Hiya Bruce!
Wouldn't that make more of an anamorphic gate? Or are you saying the gate is already full silent apeture as opposed to academy? The camera is centred on academy tho right? or does this vary by Konvas version? I could imagine the very early grey Konvai with the rheostat/hand crank might be centred on silent?

Sorry, I confused Bruce.

"
Now you are talking about super 35 1.85:1. This is a whole new deal.

Olex is correct that the shutter will not cover the extra width of a super 35 gate. However he is not correct in his assertion that it must be factory made.

You will be asking for a lot of expensive work if you want to go to super 35."


Mr Zimmerman, how much did you pay for this?
