aaton 16mm eyepiece

does anyone know if the later eyepieces...XTR etc. have zoomable eyepieces for critical focussing?
I'm talking about a standard length eyepiece.

holds the closable light trap and the view of the ground glass is amazingly better. I can easily see all of it. So I'm going to
widen the hole in the eyepiece and adapt the light trap to suit...hopefully this will improve vision.
Presumably the XTR has this already built-in...or is it a totally different optic?

I believe there is a wider view optic for the XTR, for Super 16. From memory I had this element fitted to my LTR viewfinder, replacing the older version. You can check with an Aaton dealer. There were so many mods done to the camera at the time, I've forgotten some of the details.

Thanks brian...nice to know it's possible.
I tried a similar thing with my LTR and did not have the same experience as Brian. Opening the eyepiece did not help me see the whole Super 16 frame, without having to move my eye back and forth. On a later XTR I owned (not a Prod or Plus) I was able to set up the eyepiece by creating a slight extension that fit in the light path between the fibre optics screen and the eyepiece. That worked pretty well, but was only doable on the XTR eyepiece assembly, not the LTR.

Yes, perhaps more a question of degree, on my LTR you can't see all the corners without a scan, but you can just about see the Super 16 frame marking on either side without scanning. I remember the enlargement being a big improvement over the standard LTR eyepiece aperture which involved a very deliberate scanning action, but it's not the same as an XTR Prod.

Well at least there will be an improvement...I must get hold of an XTR prod for a little test too to see the difference.
The LTR's Viewfinder was always like sitting in the front row of the cinema compared to other viewfinders, that becomes a problem with the wider aspect ratio of Super 16.
