Leica APO Summicron SL 50mm F 2 ASPH Avis | 54 Données comparées

The Jonathan Slack review of the Leica APO-Summicron-SL 50mm f/2 ASPH lens on Macfilos describes the product as a near-perfect optic that sets a new standard for the L-mount system. The pros highlighted in the review focus heavily on its outstanding optical performance, which achieves almost zero chromatic aberration due to its complex apochromatic design. This correction sharply increases contrast at the exact point of focus, creating a rapid, smooth transition into a beautiful bokeh that mimics the shallow depth of field typically found on faster f/1.4 lenses. Furthermore, its autofocus is exceptionally fast and quiet, and it features an impressive 1:5 magnification ratio that allows for a close focusing distance of just 0.35 metres. The reviewer also praises the lens's tactile manual focus response and its excellent rendering consistency across different camera bodies like the Leica SL, Leica CL, and Panasonic S1. Conversely, the review notes a few notable cons, primarily centered around the physical footprint of the lens. Weighing 740 grams, it is explicitly described as "not light," which might cause physical strain during extended handheld shooting for...

The Leica APO-Summicron-SL 50 f2 Asph is a near-perfect L-mount standard lens that delivers incredible sharpness, contrast, and smooth bokeh across all apertures. Architecturally, the lens uses an intricate optical design consisting of 12 elements in 10 groups, including three aspherical lenses. Its near-zero chromatic aberrations significantly boost contrast at the exact point of focus, creating a rapid drop-off into background blur that mimics the shallow depth of field of an f/1.4 lens. Mechanically, it boasts a highly useful 1:5 magnification ratio with a close-focusing distance of 0.35 metres, paired with fast, quiet autofocus performance. Furthermore, its manual focus ring is precise, and it balances excellently for full-day shoots on full-frame bodies like the Leica SL and Panasonic Lumix S1. However, the lens does present a few compromises for potential buyers. Weighing in at 740 grams, it is notably heavy for a relatively modest f/2 maximum aperture lens. While it successfully gathers less light than faster f/1.4 alternatives, this smaller aperture relies heavily on modern sensors to compensate in low-light environments. Additionally, the manual focusing operates strictly via an electronic...

In this field report from Qimago, Mehrdad evaluates the Leica APO-Summicron-SL 50mm f/2.0 ASPH lens using a Leica SL2s body. The primary pros highlighted in the review focus heavily on the lens's technically exceptional optical performance. It delivers an incredibly high level of sharpness across the board, with well-controlled vignetting and virtually no distortion. Structurally, it features a valuable, durable construction that fits well proportionally with the bulky SL camera bodies, handles a 0.35m close-focusing distance, and includes an electronically controlled aperture alongside a highly functional, rubberized focus ring. However, the review details several prominent cons, specifically focusing on its lack of aesthetic charm and emotional "soul". Mehrdad critiques the exterior design as "deadly dull" and plain, describing it as a minimalist black tube with a rather long lens hood that lacks an aperture ring. Furthermore, despite its 740g weight being appropriate for the system, the setup feels naturally top-heavy. Ultimately, the reviewer finds that the lens draws images too perfectly, resulting in a beautifully corrected but somewhat sterile image output. The bokeh, while okay, misses the harmonious blend of...

In his Konstantin Kokoris review, the author highlights the Leica 50mm APO Summicron-SL as his favorite everyday 50mm option within the L-mount alliance due to its unparalleled balance of usability and performance. The pros of the lens center heavily on its elite build and optical properties. It features a minimalist, completely weather-sealed, all-metal body with no unnecessary buttons or switches, giving shooters extreme confidence in harsh weather like tropical storms. Optically, the highly praised apochromatic (APO) correction completely eliminates chromatic aberrations, resulting in rich colors that "pop" right out of the camera, silky smooth bokeh, and a profound 3D subject separation that visually feels faster than its actual f/2 aperture limitation. Furthermore, despite the author's used copy requiring an autofocus motor repair, he found the overall autofocus tracking to be consistently snappy and reliable. Conversely, the review notes several distinct cons that may discourage certain buyers. The most prominent downside is the lens's prohibitive budget constraint, making it a massive financial hurdle even when purchased secondhand. Structurally, the all-metal configuration makes it relatively heavy—matching the weight of much faster f/1.2...

The Leica 50mm APO-Summicron-M ASPH ƒ2 is a highly over-engineered, ultra-compact prime lens designed to establish a new standard for optical sharpness and resolution. Structurally, it features an 11-blade aperture construction and a complex 8-element design that incorporates a rear floating element to maintain exceptional contrast during close-up shots. The lens excels by delivering razor-sharp performance from corner to corner at its maximum aperture, realistically balanced color saturation, and a pleasingly neutral, creamy bokeh free of onion-ring artifacts. Furthermore, its advanced apochromatic correction nearly eliminates distortion and vignetting, drastically reducing the time a professional photographer needs to spend on optical corrections in post-production. Ergonomically, the lens is exceptionally petite and lightweight at 300 grams, featuring a space-saving built-in hood, a practical focusing tab, and an extremely tight build tolerance. Despite these heavy pros, the major con is its staggering price tag of USD $9,095, making it over 70% more expensive than Leica's non-APO 50mm Summicron sibling. While the reviewer noted that the lens successfully resisted flaring or yielding aberrations during testing, user feedback in the comments highlights a potential con...

In this review, Steve Huff evaluates the $8,000 Leica 50mm Summicron f/2 APO lens, focusing on its performance when adapted to the full-frame mirrorless Leica SL camera. He praises it as a hand-constructed optical masterpiece that effectively enhances the capabilities of the camera's sensor, delivering contrast, vivid color rendering, and exceptionally smooth "buttery" bokeh. The lens's standout strengths include an absolute lack of distortion, zero chromatic aberration, outstanding micro-contrast, and flawless corner-to-corner sharpness when used on native Leica bodies. Furthermore, using it on the Leica SL eliminates rangefinder alignment issues, making manual focusing highly precise and enjoyable through the camera's large, bright electronic viewfinder (EVF). However, the lens has several prominent drawbacks, chief among them being its exorbitant price tag, which makes it an unjustifiable "want" rather than a "need" for 99.9% of photographers. Huff notes that early production batches suffered from flare issues, causing Leica to discard large amounts of glass before refining the manufacturing process. Additionally, its elite optical performance drops off drastically when adapted to cross-brand systems; when tested on the high-resolution Sony A7RII, the lens suffers...
