Sorry, i didn't read right.....behind the anamorphic...interesting.
Are you getting a vignette with your 67mm .25 diopter? If not, then I don't see any problems.
What aperture were you shooting the above images at?
Here's the results of the .25 diopter behind the lens. This does not effect minimum focus distance, but it does improve the image significantly as you can see in the attached pic.
EDIT: Attached a jpg of a Scarlet X still @ f4 with the .25 Diopter behind the lens
@leoj I've had mine apart, and it's a very open unit, from back to front. Best place to seal is inside the little protruding hood. But it will be tricky to do so.
I've actually hack sawed the front of mine off now, so it's really simple to tape and seal. Advantages of hacking the front off, are being able to push it up to a circular aperture matte box easier and use wider lenses. My 14-140 now works at about 15mm without vignette now, where previously it was around 17-18mm. I'm also looking at adhesive Velcro for the front, to mount a hi-tech mark 4, 2 slot 100mm filter holder with rotating 105mm ring (for pol).
@plasmasmp I don't think you will struggle in the 2-5m range with many lenses that will require a larger diopter before vignette. The 20/1.7 works with a 72mm diopter taped right up to the front element. The 14/2.5 works well wide open without any diopter.
Just wanted to bump this topic - I've been testing with a Schneider .25 diopter 67mm in diameter that is great for 2-5 meters. If only I could get one larger.
Hello does anybody have a good solution for less dust to enter in the Inside of the 7200 ?
I heard some tape is good but where to seal it up not to sure
