Hi Everyone. I was hoping to find any advice (and share my tiny bit of experience with this set-up) on shooting with the Iscorama on the Sony A7S while recording in 4K on the Atomos Shogun. Fisrt off, does anyone have any experience with this? My wee bit of experience with this set-up came after the latest Atomos firmware update (6.4 which allows for anamorphic de-squeeze) was released, I shot a super quick test to see how this would actually look and to really just see if it would actually work at all. I used a Helios 44m-2 58mm f2 as the taking lens, had the A7S in standard non-APS-C mode and just rolled a bit in my living room (so not really a test per say.) Well after dumping the clip into FCPX and performing the de-squeeze, it all looked pretty great. No vignetting with the Helios and the image was solid top to bottom and side to side. The only anomaly that I noticed while shooting the clip was with the Atomos screen as I panned the camera. The top third of the screen seems to lag and stretch during the pan which in my guess an issue with the Shogun scanning (I checked the footage in FCPX and there is no such anomaly.) Maybe this can be fixed with the next firmware update. Many thanks in advance and I look forward to the discussion!

Really beautiful, thanks for sharing.

If I need to shoot in the cold for long periods of time, I will acclimate my lenses to the outside temperature.  For example, I will take my lens case (with the lid OPEN) and lock it in my car or place it in my garage an hour or so prior to shooting.  A warm humid interior is the culprit for exterior fogging.  Then when ready to march out into the cold to shoot, toss in some silica gel packs like this into the lens case then close it:   http://www.filmtools.com/silgelselin.html   Moisture+Cold=Fog   If you cannot acclimate the lenses, purchase some disposable hand warmers and place them right on top of the barrels (taking and Kowa) if you start noticing fog.  Another great use for the hand warmers is to keep your batteries warm(-ish) to get better performance.  Wrap the hand grip with one and also toss some into your bag next to the fully charged spares.     As for filters I use both screw-on Series 9 and square 4x4.  I have yet to find 4x4 diopters so I screw on the diopter(s) on the front of my Isco and then slide the front of the lens into the donut of a small 4x4 matte box that is set on 15mm rails.  Another advantage of 4x4 matte box is that I often use ND graduated filters and a polarizer which just don't work on the front of the Isco (the Isco's focus barrel is the front-most barrel and turns when focusing).     I agree with Bioskop that your 90mm Leica would be perfect.  My favorite taking lens is a Nikon 85mm 1.4 AIS.  I'm also playing around with a 50mm Nikon Series E pancake that has a bit of "falloff" at 1.8 but not a full vignette that would make me discount it entirely.     Good luck, stay warm! 

Beautiful footage.  What's your set-up?

Tony, are you saying that it's perhaps possible with your prescribed "base" lens?  This may be a tall order, but is there anyone out there with an Anamorphot, 100mm (in 35mm format) and 5D III to give it a go?  

Hello all.     I was curious if anyone has tested the Bolex 8/19/1.5X Anamorphot with a Canon 5D mark III.  Please correct me if I'm wrong, but I've only found evidence of the lens paired with the GH2, 7D and BMCC.  Many thanks in advance for any help on this topic.
