50mm Nikon vignetting on (early)Iscorama 36/full frame combi

[wilco73]

Hi All.

 

I have a Sony A7S coming in tomorrow and am looking at a good wide lens for my re-housed Van Diemen Iscorama. The Iscorama is a early 36 (slight smaller rear end) pentax mount but re-housed by Van Diemen. I tried the Nikon 50mm F1.8 as a taking lens on my Canon 5DMKIII but this one has a lot of vignetting.

 

Now the front glas of the Nikon lens lies pretty deep (see picture) in its own housing so the distance between the rear end of the Isco and the front element of the Nikon 50 mm lens looks pretty far housing of its own housing. (I think its more than one centimeter) This might be the cause of the vignetting. Now i know that 50mm should do the trick but my question is will it work on the Nikon 50mm E series pancake version? This lens has no deep housing on the front element (like on te picture)so this might work.

 

Can anyone do a short test before i buy one. I know the 50mm E serie is cheap but i have plenty of 50mm lying around here collecting dust already ;-) 

 

Thanks guys!

I dont know about the e series but with the older nikkor-s 50 1.4 (the first one) i get the lenses so close I fear to scratch them.
The lens itself isnt a stellar performer but it has a very nice caracter. Black and White nightscenes look specially great.

I have E 50 1.8 lens. IMO, not much difference. Basically, 1.5 and 2x anamo
