Despite being mirrorless, the SL isn't that far off in size from your typical SLR.
I'm not ready to call it our Editors' Choice—the much more affordable Sony Alpha 7 II is an easier sell if you're looking for a mirrorless full-frame camera.
Design and Lens System The SL takes some of its design cues from Leica's digital medium format S SLR lineup, and others from its long-discontinued 35mm R SLR line.
But at its heart it's a new design, free of the shackles of legacy technology.
Its body is slimmer than an SLR—there's no mirror box after all—but the handgrip is just as substantial as that of a full-frame SLR like the Nikon D810.
The body is cut from aluminum and anodized with a black finish.
The handgrip is covered in a textured material to improve the grip; the texture also covers most of the rear.The SL is sealed against dust and moisture, and native lenses incorporate a gasket at the mount point, so you can feel comfortable photographing in inclement weather.Leica has earned a reputation for being behind the times in the modern digital world.For years, its flagship M line lagged behind others in tech and features, and its more affordable D-Lux and V-Lux lines were simply Panasonic cameras with Leica logos.But after this year, anyone criticizing the company on this is doing so based on history alone.Following hot on the heels of the very modern Q compact, Leica is bringing its first autofocus full-frame mirrorless camera to market.
