If someone asked me to recommend just one lens for a Leica M camera, my answer would be immediate: a 35mm lens. Whether you choose the legendary 35mm f/2 Summicron or the faster 35mm f/1.4 Summilux, you’ll own a lens capable of photographing almost everything you’ll encounter. Street photography, travel, family moments, landscapes, environmental portraits, documentary work, architecture, even food photography—the 35mm focal length handles it all with remarkable confidence.
It’s no coincidence that so many of Leica’s greatest photographers built their careers around 35mm.
The Perfect Balance
The beauty of 35mm lies in its balance.
A 28mm can sometimes feel too wide, introducing distractions around your subject. A 50mm can feel restrictive when you’re indoors or working in tight spaces.
The 35mm sits perfectly in between.
It captures enough of the environment to tell a story while still allowing your subject to remain the focus. Images feel natural, immersive and engaging without obvious wide-angle distortion or excessive compression.
Many photographers describe 35mm as seeing the world rather than simply photographing it.
It Makes You Part of the Scene
One of the reasons Leica rangefinders are so enjoyable is that they encourage photographers to get closer.
A 35mm rewards that approach.
Rather than standing back and isolating subjects with a telephoto lens, you’re encouraged to step into the moment. Your photographs become more intimate because you’re physically involved in the scene.
This connection often produces stronger storytelling than simply zooming in from a distance.
One Lens for Every Situation
The versatility of 35mm is remarkable.
On a typical day you might photograph:
- A sunrise landscape.
- Coffee at your favourite café.
- A candid street portrait.
- Your children playing.
- Architecture while travelling.
- Dinner with friends.
- Night scenes after sunset.
The same lens comfortably handles all of it.
You spend less time thinking about which lens to mount and more time looking for photographs.
Summicron or Summilux?
This is the question every Leica owner eventually asks.
35mm f/2 Summicron
The Summicron is arguably Leica’s greatest all-round lens.
It’s compact, beautifully balanced on every Leica M body, exceptionally sharp, and produces stunning contrast and colour. At f/2 it gathers plenty of light while remaining small enough to disappear in your bag—or around your neck all day.
Many photographers appreciate that the smaller size keeps the Leica M system exactly as it was intended: discreet and unobtrusive.
35mm f/1.4 Summilux
If you regularly photograph in low light or enjoy a shallower depth of field, the Summilux offers an extra stop of light.
That additional aperture provides greater subject separation and makes night photography even more enjoyable. The rendering wide open has a distinctive Leica character that many photographers absolutely love.
It’s larger, heavier and considerably more expensive than the Summicron, but for many photographers the look is worth every cent.
Why Not a 50mm?
The 50mm has produced some of the greatest photographs ever taken, and many photographers will always prefer it.
But if you’re only buying one lens, the 50mm asks for more working distance. Indoors, narrow streets and small rooms can quickly become limiting.
The 35mm simply adapts more easily to everyday life.
You can always crop slightly if you need a tighter composition. You can’t always step backwards.
Why Not a 28mm?
The 28mm is excellent for travel, architecture and dramatic environmental scenes.
However, it demands more careful composition. Get too close and faces begin to stretch. Get too far away and subjects become lost within the frame.
The 35mm is more forgiving.
It provides context without overwhelming the subject, making it easier to produce consistently strong images across many genres.
The Lens That Lives on Your Camera
One of the biggest advantages of choosing a 35mm is that it becomes the lens you never take off.
Instead of carrying multiple lenses and constantly wondering which one you should use, you learn to see in one focal length.
Over time, framing becomes instinctive. You begin recognising photographs before raising the camera to your eye.
That’s one of the greatest strengths of the Leica M system: simplicity.

Final Thoughts
If I were forced to sell every Leica lens except one, I’d keep a 35mm without hesitation.
The 35mm Summicron offers one of the finest combinations of image quality, size and versatility ever produced.
If you value maximum speed and beautiful shallow depth of field, the 35mm Summilux is a spectacular choice.
Whichever you choose, you’ll own a lens capable of documenting an entire lifetime.
Photography isn’t about having every focal length available. It’s about knowing one lens so well that it disappears from your mind, allowing you to concentrate entirely on light, timing and storytelling.
For a Leica M photographer, that lens is almost always a 35mm.
