Can anyone suggest the best third party AF lens as an alternative to the pricey Leica 50mm SL Summilux but that still has a bit of the impressive 3D separation that the SL lens has? I have the Novoflex EOS-SL adapter and was thinking about the Canon 35mm f/1.4L II, the Sigma 35mm or 50mm f/1.4 Art lenses, or the Canon 50mm f/1.2L. The AF does not have to be super speedy but it has to work with the Novoflex. I am leaning towards the Canon 35mm L just because I slightly prefer the 35mm FOV, but am open to either. TIA!
