@don carlos It drastically differs depending on the lens. On the Kowa-8 2x lens I can use the full range of the 45-175, but it's a rare and fantastic lens. I don't have any of the Bolex lenses so I can't say for sure. At f/4 to f/5.6 you are looking at sharp images through the range that is usable.

Thanks for the swift response. I am going to give it a try and share my findings. On a side note I was considering the faster 35-100mm 2.8, however it has a 58mm outer diameter so I will have to use a step down ring 58-52mm to attach my bolex lens, I was suspicious if that can cause vignetting, do you have any opinion on that.

Also, my planned short film will be shot mostly inside a moving train so I guess I am definitely going to need a diopter, any recommendations? I have only heard of the ones that cost a bomb. Would you know whether the ND Filter should be the final attachment or should it be the diopter.

Zooms work fine depending on the situation. Your issue is going to be how far back the actual lens is from the sensor/rear element. An example: When using an 8mm anamorphic on a prime lens (Let's say my Aivascope) 28mm is vignette free. But when I use my 12-35mm zoom, it has a vignette the full length, even at 35mm. It's because when you zoom, the lens extends further away from the rear element and sensor. On the other spectrum, my 45-175mm zoom is internal, so the lens stays the same length. I can find the limit of all of my anamorphics with that lens. I first discovered this while playing with an old HDV cam. When the internal lens zooms, the whole rear moves back, pushing the anamorphic further from the rear element and the vignette didn't go away for the whole zoom range.

The rear element of the Bolex  Moller 8 is pretty small, if I remember correctly. Also, it's really heavy. You have to watch for your zoom motors (if it has one) and focus motors and make sure it's not too much of a burden.

I hope this explains what I'm trying to say. I can shoot some examples if you need me to.

I have a GH2 and Bolex Moller 8/19/1.5x. I use the 52mm redstan adapter. The widest I have successfully shot without vignette is 35mm, I am about to buy the lumix 45-175mm solely for the purpose of using the bolex anamorphic lens with it. Can you please confirm what focal length range could you use without vignette?

my purpose of buying this was that I didn't find any other more suitable for the bolex lens. This lumix has a 46mm filter size, internal focusing and zoom and relatively affordable. Buy reading your comment about the optical element within the barrel move farther has got me thinking whether I will be able to use it with bolex for the entire range or not. Please suggest your findings. Thanks you
