Optics and Lenses -This forum is aimed towards the TECHNICAL side of photographic OPTICS and LENSES. There will be some overlap by camera/manufacturer, but this forum is for the heavy duty tech discussions. This is NOT the place to discuss a specific lens or lens line, do that in the appropriate forum. This is the forum to discuss optics or lenses in general, to learn about the tech behind the lenses and images. IF you have a question about a specific lens, post it in the forum about that type of camera, NOT HERE.
Has anyone done a test or just a comparison to see which fast 35s - M or LTM mount - are most resistant to flare? I have used two Summiluxes - pre-asph and asph second version - but have not tried others. I need a fast lens that doesn't flare horribly with light sources in the frame; f 2.0 and slower won't do.
