Which 35mm adapters aren't soft at the edges?

I know Letus is guilty of this. And the Brevis footage I've seen is too. Is this just the cost of a 35mm adapter? Or is there a way to make them sharp on the edges?
 
M2 when hard mounted and the SGpro Rev.2-- the latter being the easiest to see in existing footage. Seems as though m2 users are just catching onto the hard-mount deal. I think the Brevis as well, but I'm sure of the other two.

Do a search for member: SOTTY and the threads her started in the HVX footage section. He's using Zeiss glass and another brand and getting some super sharp results with the M2/HVX and a Hard-Mount setup.
 
a few stills from this weekend. Brevis35, CineFuse 1 (CF1), Nikon 50mm f/1.2, ND9, Polarizer. footage here.

Nice one Zak. :thumbsup: Is this CF1 or CF1e diffuser for this footage?

CF3 should hold up well with your 50mm f1.2 lens, wide open. Is you CF3 the new one (CF3e)? Thanks.
 
I've got the new CF1L (referred to as CF1e above) in my Brevis. No vignetting with longer lenses. A little vignetting with my 35mm (as predicted by Dennis at Cinevate), but not enough for me to bother switching the elements. I have had no issues with edge-to-edge sharpness, but I don't think I'm as strict about this as others.
 
SGpro, Brevis35, "M2" I put this in quotation marks because i find that the M2 tends to have a vingette that is pretty consistent though all the footage ive seen.
 
Alot of the time vinetting comes from or is compounded by the lense. i havent had vinetting with my m2 or brevis. i dont use zoom lenses, zooms have the most problems with it. Especially cheap ones.
 
You can reduce but never get rid of the soft edges - the only solution is to use better screens and zoom in on the image more - losing a large part of the point of 35mm.

The best suggeston is to increase your light levels. The physics behind 35mm adapters and the nature of apertures doesn't really provide a way to eliminate the 'hot spot' issue completely... Focus more on the quality of on set lighting and the speed / quality of your glass
 
you surely can eliminate soft edges. the trick is using a well crafter achromatic diopeter. Wayne kinney and Jim Lafferty both use a spectacular diopeter. The SGpro is pin sharp corner to corner as is the Go35pro. This is 90% of the reason i chose these adapters. the old SGpro rev1 has a Macro, and it suffered from soft edges.
