Okok, I received some step up / down rings yesterday. 
 
	Taking lenses for my Pocket 4K with the Elmoscope type 1 I used were 35mm T2.2 Meike cine lens and a Canon FD 50mm 1.8. 
 
	Using the anamorphic mode for the BMPCC4K I got decent results: the 35mm is slightly vignetting (not a hard vignette, just a little Grey corners), so I actually like it the way it is. Cropping in, it's more than usable. 
 
	The 50mm is giving me a headache, because the adapter (FD to Mft) is moving and I don't have a lens support yet. Still the overall cheapest solution if you want to get into anamorphic. 
 
	There isn't much coating, Direct light from the front lights up a huge horizontal oval Grey (especially with the 35), making the picture totally Grey in the corners, lens flares are warm blue.
