Photographing with Leica M Camera Lenses
While modern optical technology has resulted in a huge variety of lenses with a whole host of features, few manage to match the quality of glass and purity of the M mount. With their lenses coated to render neutral colors and without the over saturation that is a feature of some modern models, they're seeing a resurgence among serious photographers. They're generally only available in short focal lengths and lack autofocus motors, but are physically small for easy carrying.
What Is the M Mount?
Introduced in 1954, this bayonet-style mount was faster to attach than previous screw-mount lenses such as the M42. The company's lenses are renowned for their build, quality, and use of good glass, which is why they are highly sought after by photographers to this day.
- Almost all of the Leica M lenses are primes (fixed focal lengths), although you can find a wide-angle Tri-Elmar that you can switch between 16mm, 18mm, and 21mm to offer some versatility at the wide end of the focal spectrum.
- M lenses are also available as 50mm, 75mm, and 90mm, with dedicated macro adapters that enable close focusing on minute subjects.
Are M Mount Lenses Compatible with Other Camera Bodies?
You can use M mount lenses on some other manufacturers' mirrorless camera bodies with the use of the right adapter, which you can easily purchase online.
- Keep in mind that because the lenses are manual functioning, you need to shoot and focus in manual mode regardless of your camera's features when using with an adapter.
- Leica M lenses are not compatible with Canon bodies without modifications, which you can perform with success. You can use R mounts on Canon camera bodies with the use of an adapter, but can operate only in stop down metering mode.
What Should You Look for When Buying M Mount Lenses?
The M mount lens that's right for you depends on the focal length you are after, the aperture you want to be able to shoot with, and the build quality you desire, as well as the availability of an adapter to make it compatible with your camera body.
- You can find prime wide angles ranging in focal length from 18mm to 28mm and equipped with apertures from f/3.8 down to f/1.4.
- There are four different 50mm M mounts to select from, including an f/2.5 and an f/0.95.
- At the longer focal lengths are two 75mms at f/2.5 and f/2.0, while there are three 90mms—f/2.0, f/2.5, and f/4—and a 135mm that features a built-in sliding lens hood.
