Leica APO Summicron SL 75mm F 2 ASPH Análisis | 54 Datos comparados

The Leica APO-Summicron-SL 75mm f/2 ASPH. is an Editors’ Choice-winning L-mount lens offering exceptional edge-to-edge sharpness, a robust weather-sealed design with AquaDura coating, and a compact form factor for its class. It delivers superb optical performance with a 19.7-inch minimum focus distance, making it ideal for high-end portraiture and detailed, close-up work. While offering outstanding image quality, the lens is not optically stabilized—a potential drawback on older, unstabilized bodies—and features a high $4,750 price point along with visible, though easily corrected, vignetting. Despite these limitations, its pristine construction and performance justify the investment for professionals.

The Leica APO-Summicron-SL 75mm f/2 ASPH is a highly advanced prime portrait lens that delivers phenomenal, reference-class image quality with a compact form factor. Featuring an optical layout of 11 elements in 9 groups, the lens utilizes specialized anomalous partial dispersion and aspherical glass elements to completely eliminate chromatic and monochromatic aberrations. Optically, the lens outperforms the legendary APO-Summicron-M 75mm counterpart by providing superior edge-to-edge sharpness, exceptional contrast, and a compressed sharpness curve that yields a highly defined three-dimensional look with silky, cinematic bokeh. Mechanically, it introduces a Dual Syncro Drive internal stepping motor system that secures incredibly fast, precise autofocus, alongside a highly responsive fly-by-wire manual focus ring utilizing alternating magnetic fields for exceptional tactical feel. Several prominent advantages and minor drawbacks define this premium optic. On the pros side, the lens offers an outstandingly close minimum focusing distance of 0.5 meters (offering a 1:5 reproduction ratio), full weather sealing, robust all-metal construction, and an optimized rear-heavy physical balance that shifts the center of gravity perfectly toward the camera mount. It is also significantly lighter and more portable than...

The Leica APO 75mm f/2 Summicron-SL ASPH is a highly capable lens that stands out as the system's first truly practical native option for everyday documentation and recreational use. Unlike its bulky predecessors—such as the 50mm f/1.4 Summilux-SL and various heavy zoom lenses—this 75mm prime features a significantly smaller and lighter form factor that ensures comfortable handling during extended photowalks. In terms of performance pros, the lens delivers impressive edge-to-edge sharpness, exceptional micro-contrast, and remarkably precise detail rendering. Optical aberrations, including vignetting and color fringing, are kept exceptionally well under control even when shot wide open at its maximum f/2 aperture. Furthermore, despite lacking built-in image stabilization, the reviewer successfully achieved tack-sharp focus at slow shutter speeds well below the standard reciprocal rule. However, the lens is not without its performance trade-offs and structural challenges. A notable drawback is that its rendering lacks a prominent three-dimensional "pop" at maximum aperture, falling short of a typical wide-open Summilux look unless it is shot at a very close minimum focusing distance in low ambient light. The raw, unoptimized image exports can also...

The Leica APO-Summicron-SL 75/2.0 ASPH is a highly impressive, optically near-perfect short telephoto lens built from scratch with 11 elements in 9 groups to deliver elite performance for the SL system. It is exceptionally well-built with a tank-like construction and a steel-based hood, making it forward-compatible with future high-resolution sensors like a potential SL2. Its optical strengths include incredible wide-open sharpness, non-clinical smooth bokeh, and an excellent contrast transition between focus areas. Furthermore, it shows virtually zero technical flaws, proving to be entirely free of chromatic aberration, vignetting, or purple fringing, while maintaining maximum contrast even when shot directly into the sun. However, the lens has notable drawbacks regarding its physical footprint, autofocus capabilities, and tactile experience. It is a massive and heavy lens—larger and weightier than a Canon 5DmkIV paired with an 85mm f/1.8 lens—which may alienate rangefinder users accustomed to compact M-system glass. Autofocus performs reliably for static portrait sessions but struggles in low-light and fast-paced environments, where the focus hunts extensively and suffers a high failure rate on moving targets. Additionally, the non-mechanical magnet-driven manual focus concept...

The DPReview sample gallery for the Leica APO-Summicron-SL 75mm F2 ASPH showcases a high-performance, short telephoto prime, demonstrating exceptional edge-to-edge sharpness from its maximum f/2 aperture,, excellent chromatic aberration suppression, and a fast, quiet "Dual Synchro Drive" autofocus system. However, the 720g, 90mm-sized lens is considered heavy and bulky, produces a "clinical" rendering with occasional busy bokeh at edges, and carries a high $4,750 USD price point.
