Why you can trust Digital Camera World
The Leica APO-Summicron-SL 28mm f/2 ASPH is a rather heavy lens, which took me by surprise when you see that it is a neat, and compact lens. It weighs in at a hefty 24.7oz / 700g and the price... an eye-watering $5,650 / £4,650!
Price aside, this is probably one of the most solid mirrorless primes I have ever laid eyes on, as it should be for that amount of wonga - but you certainly get what you pay for with tremendous image quality.
It features a fast and bright f/2 aperture and can be stopped down to f/22. With a minimum focus distance of just 9.4" / 24cm, this 28mm lens for the SL-System can certainly be used to cover photography genres such as street, reportage, and of course landscapes - but does this lens live up to the legendary 28mm hype?

Leica APO-Summicron-SL 28mm f/2 ASPH. key features

The Leica 28mm APO- Summicron-SL f/2 ASPH. is built like a tank with only the best materials used, and functions as expected from the renowned German manufacturer.

While using the Leica 28mm APO-Summicron-SL f/2 ASPH paired with a Leica SL2-S I found its weight to have a nice balance in the hand, which was a nice surprise, as the SL2-S isn't a heavy camera, and the lens did not feel top-heavy. Stopped down to f/8 or f/16, you will really see how well this lens performs in bright daylight. Every image was razor sharp, giving a lot of clarity and depth to each image. However, images shot wide open at f/2 looked incredible and did well in isolating subjects from the background with a pleasing and dreamy look.
Leica APO-Summicron-SL 28mm f/2 ASPH. Performance
I shoot a lot of images on a 21mm for street photography, I found the 28mm of the APO Summicron-SL an amazing focal length for street, candids, landscapes, and pretty much anything you want to point your camera at - it’s a very nice and useful lens indeed, and it is one of the most compact SL prime lenses on the market - pair with the Leica SL2-S made for a really enjoyable package to have around my neck or flung around my should for all day shooting.
The only grumble I can really make on the Leica 28mm APO-Summiron-SL f/2 is that there is no distance scale on the lens like you would find on the best Leica-M lenses - while I see why Leica has done this across the whole range of the SL lens range, it does make it tricky when you want to quickly shoot from the hip while covering street photography or just wanting to capture a quick candid moment with the family.
However, when you have the camera to your eye, or using the rear screen, the 28mm is extremely fast to focus, while this is mostly down to the SL2-Ss tracking system - every image I took across this review was sharp, and it never missed a beat.
Obviously, this lens is able to shoot wide open at f/2, which lets in a tremendous amount of light and makes any dimly-lit or next-to-no-light situations perfect for those who like to shoot images in all locations and at all times of the day, even at night. I found the Leica 28mm APO-Summicron f/2 ASPH. lens to be sharp wide-open with amazing separation of subject, however, I think the sweet spot really is between f/2 for low-light shooting and f/8 for when the sun is at its highest. Overall, I'd say the lens produces fantastic images with rich tonalities and high clarity, which I was really pleased with.
