Sony FE 100mm F 2 8 STF GM OSS Bewertung | 54 Daten im Vergleich

The ePHOTOzine review highlights the Sony FE 100mm f/2.8 STF GM OSS as a lens delivering incredible sharpness, zero distortion, and exceptional, smooth background bokeh due to its integrated Apodization (APD) element. The 700g lens is praised for its robust build, effective Optical SteadyShot (OSS), and fast, quiet autofocus, making it a stellar performer for close-up and portrait work. Conversely, the specialized design results in a T5.6 rating, creating a 75% light loss compared to a standard f/2.8 aperture, which limits low-light performance. Other cons include noticeable focus breathing, lack of an aperture ring lock, and a focus-by-wire system deemed less precise than mechanical alternatives.

The Ken Rockwell review highlights the Sony 100mm STF as a specialized portrait lens, featuring an internal "apodization" filter that produces exceptionally smooth, soft-edged out-of-focus bokeh. Pros include ultra-sharp in-focus performance, a silent DDSSM autofocus motor, and a macro-switching ring that reduces minimum focus distance. However, the lens has a significant drawback: the apodization element limits light transmission to T5.6, despite having f/2.8 depth of field, making it inefficient for low-light scenarios. Additional cons noted in the review include a lack of traditional, physical distance indicators and a plastic, rather than metal, filter thread.

The DPReview sample gallery and analysis for the Sony FE 100mm F2.8 STF GM OSS highlights a specialized portrait lens offering exceptional sharpness, even on high-resolution sensors, and a unique, smooth background bokeh produced by its built-in apodization (STF) filter. Key advantages include rapid direct-drive SSM autofocus and a useful 0.25x macro switching feature for close-up work. However, the specialized design introduces notable cons, most significantly a light transmission penalty that drops the effective aperture from f/2.8 to T5.6, severely limiting low-light capabilities. The review further notes that this T-stop limitation, combined with the extreme smoothing, can cause autofocus to struggle in dim, backlit conditions, and may not suit photographers looking for more defined, traditional bokeh highlights.

The Sony FE 100mm F2.8 STF GM OSS is a specialized, high-performance G Master prime lens designed for full-frame mirrorless cameras, making it highly appealing to serious portrait and wedding photographers. Its standout feature is an internal apodization (APD) element that acts like a graduated neutral density filter, smoothing out-of-focus highlights to deliver exceptionally clean, circular edge-to-edge bokeh without "cat-eye" distortion. Built to withstand the elements with dust and moisture resistance, the lens features optical image stabilization, a versatile close-focus ring that provides 1:4 macro magnification, and a de-clickable physical aperture ring favored by videographers. In lab testing, it displays outstanding optical sharpness, recording an incredible 4,290 lines at its widest setting. However, this unique design introduces notable trade-offs, primarily regarding light transmission and cost. The primary con is that the APD filter significantly compromises its light-gathering capability; while wide open at f/2.8 for depth-of-field purposes, it only transmits as much light as a standard f/5.6 lens (T5.6), making it a poor choice for dim or low-light environments without a flash. Additionally, at $1,499.99, the lens is quite expensive, large...

The Sony FE 100mm f/2.8 STF GM OSS is a specialized, weather-sealed G-Master lens that delivers an unmatched bokeh quality due to its unique Smooth Trans Focus (STF) apodization (APD) element. This APD element acts as a graduated filter that smoothly dissolves the edges of out-of-focus highlights and eliminates the "cat-eyes" distortion near image borders. Optically, the lens provides outstanding center sharpness and very good border resolution starting immediately at its maximum aperture, alongside negligible vignetting and highly effective optical image stabilization (OSS) that offers 3 to 4 stops of compensation. Furthermore, its robust build quality includes a dedicated physical aperture ring, a focus-lock button, and a dual-range focus limiter that allows for a helpful 1:4 maximum close-up magnification. However, this specialized design introduces several distinct drawbacks, most notably a severe 2-stop light loss caused by the APD element. While the lens maintains the depth-of-field of an f/2.8 aperture, its actual light transmission is reduced to T/5.6, and the signature ultra-smooth bokeh effect disappears rapidly if the lens is stopped down by even 1/3 of a stop. Additionally, the lens...

The Sony FE 100mm f/2.8 STF GM OSS lens is a professional-grade optic, noted for its exceptional sharpness, built-in optical image stabilization, and superior, soft-edged bokeh produced by an optical apodization (APD) element. The lens features a robust design with a smooth, quiet DDSSM autofocus system and an integrated aperture ring. The-Digital-Picture.com However, the specialized APD element restricts light transmission to a T5.6 rating, significantly reducing its low-light capability compared to its f/2.8 aperture designation. Other drawbacks include moderate focus breathing, some color fringing, and the lack of a lock switch for the aperture ring.

The Sony FE 100mm F/2.8 STF GM OSS is an exceptional full-frame short telephoto portrait lens built with a specialized internal apodization (APO) filter. This graduated, neutral-grey tinted element smooths out-of-focus edges to produce incredibly refined, perfectly round highlight bokeh blobs in both the foreground and background. Crucially, unlike soft-focus lenses, the STF design achieves this dreamy blur without sacrificing tack-sharp image quality at the exact plane of focus. Key pros of this meticulously built, weather-sealed G Master lens include its remarkable versatility for portraits, landscapes, macro photography, and action shots, alongside an ultra-sharp optical profile with virtually zero distortion, vignetting, or chromatic aberration. Furthermore, its silent and highly responsive Direct Drive SSM autofocus system handles fast-moving subjects effortlessly. The primary drawback of the lens is its limited light transmission due to the tinted APO element, which drops its maximum light collecting ability to a T/5.6 stop despite having a shallow F/2.8 depth-of-field. While built-in Optical Steady Shot (OSS) image stabilization helps offset this, the lens is still less than ideal for extreme low-light environments. Additionally, at a premium price...

The Sony FE 100mm F2.8 STF GM OSS (SEL100F28GM) lens is praised for its high-end optical engineering, versatility, and unique, ultra-smooth background bokeh. Key pros include the ability to shoot wide open for flattering portraits with smooth skin tones, a 0.57m minimum focus distance for macro capability, and a relatively light 700g weight that makes it a practical, high-quality alternative to bulky 70-200mm zooms for event photography. A primary trade-off, or con, inherent to the Smooth Trans Focus (STF) system is that the internal apodization element acts as a neutral density filter, reducing light transmission. While the depth of field matches an f/2.8 lens, the actual light hitting the sensor is equivalent to a T5.6 lens, making it less ideal for extremely dark, low-light environments without boosting ISO.
