BH #LE352SL • MFR #11184
Leica APO-Summicron-SL 35mm f/2 ASPH. Lens
Key Features
  • L-Mount Lens/Full-Frame Format
  • Aperture Range: f/2 to f/22
  • Five Aspherical Elements
  • Multi-Layer and AquaDura Coatings
A favored and versatile focal length coupled with an optically refined design, the Leica APO-Summicron-SL 35mm f/2 ASPH. is a general wide-angle prime designed for full-frame L-mount mirrorless cameras. The bright f/2 maximum aperture strikes a balance between speed and overall weight and size, offering a portable form factor along with the ability to excel in available light conditions. The apochromatic optical design uses anomalous partial dispersion glass to suppress color fringing and chromatic aberrations for high clarity and color accuracy, and five aspherical elements are also featured to reduce spherical aberrations for improved sharpness. Multi-layer coatings have also been applied to limit flare and ghosting for increased contrast when working in strong lighting conditions. Complementing the optics is a Dual Syncro Drive stepping motor, which delivers fast and quiet autofocus performance to suit both stills and video applications. Additionally, an AquaDura coating has been applied to the exposed elements and seals have been incorporated in the lens design to benefit working in harsh environmental conditions.

Additionally, an AquaDura coating has been applied to the exposed elements and seals have been incorporated in the lens design to benefit working in harsh environmental conditions.

Wide-angle 35mm f/2 lens is designed for full-frame Leica L-mount mirrorless cameras, however can also be used with APS-C models where it provides a 52.5mm equivalent focal length.
Bright f/2 maximum aperture benefits working in low-light conditions and also affords greater control over depth of field for working with selective focusing techniques.
Five aspherical elements are used to reduce distortion and spherical aberrations for improved sharpness and accurate rendering.
Apochromatic design employs anomalous partial dispersion glass to suppress chromatic aberrations throughout the aperture range for increased color accuracy and clarity.
Multi-layer coatings have been applied to individual elements to suppress surface reflections, flare, and ghosting for increased contrast and color fidelity.
Dual Syncro Drive stepping motor delivers quick, precise, and near-silent autofocus performance to suit both photo and video applications. This system also avails full-time manual focus override.
Water-repellent AquaDura coating has been applied to the front and rear optical surfaces to protect against moisture and other elements.
Weather-sealed design protects against dust and moisture to benefit working in inclement shooting conditions.

Leica APO Summicron SL 35mm f/2 ASPH. Reviews

Best lens I've ever owned

By Samuel
Rated 5 out of 5

Came from a Leica Q2 and thought that was good. This lens takes it to the next level, never seen images like this from a lens/camera. Can't ever go back to a Canon or Sony now.

Simply The Best

By Gary

Due to the virus situation I have not used this lens nearly as much as I would normally have with a new lens. However, I have been shooting in and around our condo and our outside terrace. In short the image quality of this lens is Simply The Best. Regardless of aperture setting, from f2 on up to f9 (I usually stop at f9 with an occasional f11) images are sharp across the image, crips, lovely color saturation, contrast, all are excellent. And in a first, remarkably I have not been able to detect ANY chromatic aberration; no green, cyan or purple fringing. A TRUE APO lens. A slight negative would be this lens, while smaller than I expected (this lens is like a mini or 3/4 size S lens) is still a little heavy and when mounted on my SL (601) the combo weighs just about 4 pounds. However this weight is worth the slight bother to me to have have a general purpose lens that I can shoot all day in all settings and obtain images that are as good as I've been getting. I live in downtown Scottsdale AZ and this shot is from my terrace of a sunset looking southeast.

Another reference lens from Leica

Leica M shooter for... years as well as Nikon owner. I switched to the Leica SL system with the Panasonic S1R and its 47 Mpix (did the same with Nikon Z7 and the Z 35mm lens) therefore I do have some ways to compare the two offerings. The Leica SL Apo-Summicron is always over performing the Nikon Z 35mm lens. Sharper - way sharper -everywhere on the field. Better color rendition too. No distortions visible (probably thanks to digital corrections). With the S1R/SL 35mm combo, the results are really above the M10P/Summilux 35mm, you got AF in the mix and twice the pixels count! Is this lens the new reference 35mm lens, I really think so... I have never seen this type of details and definition in any other systems before. Super expensive, very difficult to get (long waiting list), but the willing photographers will be rewarded with impressive results.

It's not JUST about the image quality for me!

Other reviewers have nailed the unprecedented image quality of this lens, and I agree with them. I use it on the SL2 and have never seen the ability to crop very heavily and get highly detailed images. What I wanted to comment on is the feel of the lens on the SL2. Like a good marriage, it adds the built from a solid block to the lens. Other excellent lenses from Sigma and Panasonic are in my lens collection and I am very happy with the image quality from them at much lower cost than the Leica SL lenses, but they feel pretty much like other DSLR/Mirrorless lenses, very nice, but NOT built from a solid block nice! A final note is that the autofocus is instantaneous and silent. As fast and quiet as any lens I have used.

Leica quality reveals in the details of the images

I am a long-time Leica shooter and have been using several 35mm Summilux and Summicron M lenses. I listened to Mr. Peter Karbe's presentation on SL lens design, and appreciate the idea of increasing contrast to give viewers a stronger perception of the three-dimensionality of the image. I love to shoot wide-open to use maximum light designed for the lens. When shooting wide-open, Summicron-SL renders images similar to Summilux but retains the depth of field of F/2.0 which fits better to my needs. This lens is indeed the best of any lens designed to date by any technical standards. The image details are alive by the rich scales of micro-contrast and micro-tones. Of course, this is a super sharp lens, but the sharpness alone will not bring life to the images. We are talking about Leica magic here! I will not hesitate to choose this one over Summilux 35mm ASPH FLE or Summicron 35mm V4 Bokeh King for the image rendition. This Apo-Summicron-SL 35mm is truly a lovely lens technically and artistically.

Finally got one to do the breathing test, and found almost no breathing. An amazing compact native L mount lens for video on S1H.
