    These were definitely sold with the black finish - fashion changes during time. Steel wool is, perhaps, not a good idea.
    It illuminates 30x40cm (12x16") fully open.

    Re: Turning a Leitz Epis Projector lens into a "Universal Epis" -apologies to Voigtlä

    Hi Steven,

    Very interesting and simple modification. I just purchased a Epidiascoop in mint condition with the f3.6/400mm lens.
    I will use the lens for my new build 310mm/310mm wet plate field camera (by Donchev camera's)
    I was wondering if you have been posting any photo's that you have shot with the Epis? Can you share some?

    I have an older 12" f4 version, it darkens the corners considerably at infinity on 8x10. I read this thread in '12 and resolved to attempt the modification myself when I got a new lathe. The new lathe is now in my garage, waiting for me to have the time to swap out the motor for one that will run on single phase. I suppose I could take a hacksaw to it, but I would like to keep it neat.

    Steve, In your first post, at the end you mentioned using front stops. Can you tell me how well this worked please.
    I was considering cutting an Epis to introduce a stop, but if it works well on the front it would same me the hassle.

    Re: Turning a Leitz Epis Projector lens into a "Universal Epis" -apologies to Voigtlä

    It was difficult enough to convert the triplet so that the central lens would move forward - so adding a Waterhouse slot between the central lens and the rear lens was a step too far!

    Mounting a stop system in front of the front lens was common until the WHS innovation of 1857. A few makers had introduced central stops before then, using split barrels or an enlongated front cells. I have used the front system on all my landscape menicus lenses, even a Plasticca as well as some (genuine!) 40's and early 50's unmodified Petzvals.
