If you could have only one lens, what would it be? For me, that lens would be the Leica Summilux-M 24mm. It’s a wide-angle lens that isn’t too wide for most purposes. It’s extremely sharp across the frame with no red or cyan corner issues. When opened up to f/1.4, you can use it for most interior shots. Best of all, I like the versatility of the lens. You can use it for clean, almost clinical shots, where everything needs to be clear with a minimum of distortion

I was already a big fan of the 18mm Super-Elmar-M, both for its wraparound perspective and extended depth of field. When paired with the M Monochrom, it becomes even more versatile for low-light photography. As for the Monochrom itself, not once did I miss being able to shoot in color. I was too busy enjoying the enhanced detail and tonal range provided by this unique camera.
