Most fixed focal length (new) R lenses are "flare free" but you have to follow the rules. NO filter. Very very clean front lens surface. The angle that the sun hits the lens front surface. I take pictures which include the sun, all the time, with my Leica R equipment. Including the sun in the frame is entirely different than the sun, outside the frame, rays hitting the lens at an oblique angle. This WILL cause a reduction in contrast and you can see it happen right there on the ground glass. In these cases you can shade the lens. But the direct rays from the sun within the frame, at least with my lenses, does not seem to be a problem. Jim
