Is there any alternative that's offer higher optical IQ than the Nokton and meets the following criteria:
- Has tab focusing
- Focuses to .7m
- Costs less than $1500.
- Opens at least to f2, and if f2 is the starting point it must be sharp and usable
- No ZM lenses: can't get along with 1/3 f stops and the little focusing nub.
From what is read the early Summiluxes might not be a step up in image quality and will be a step back in minimum focusing distance. I'd be willing to give up a couple of stops and look at early Summicrons, but only if performance at f2 is outstanding right off the bat and I don't have to close up a stop or two to achieve performance on par with the Nokton. Distortion is not an issue as much as center sharpness and good BW rendering.
