Sony 135mm F1 8 ZA Carl ZEISS Sonar T Análisis | 54 Datos comparados

The Sony 135mm f/1.8 Carl Zeiss Sonnar T* (SAL-135F18Z) is a premium A-mount telephoto prime lens delivering exceptional edge-to-edge sharpness even wide open at f/1.8, with virtually no lateral chromatic aberration. It offers excellent bokeh, minimal flare due to Zeiss T* coating, and solid build quality with a useful focus hold button. However, the lens is heavy at 985 grams and relies on a louder, slower screw-driven autofocus system, making it less suitable for fast action. It also lacks modern weather sealing and carries a premium price point for its specialized use in portraiture.

The Sony Zeiss Sonnar T* 135mm f/1.8 ZA lens is identified in the Tangents review as an exceptional portrait lens offering outstanding optical performance, razor-sharp subjects, and smooth, creamy background bokeh. Praised for its solid, heavy-duty build, the lens provides a desirable 3D pop effect, confirming its reputation as a top-tier performer, particularly when shooting wide open. Regarding cons, the review highlights that the lens relies on a louder, screw-driven autofocus mechanism and lacks internal stabilization. As an older A-mount design, it requires modern camera bodies with in-body image stabilization (IBIS) to manage stability, as noted in the analysis of its performance on Sony mirrorless systems.

The Sony A-Mount 135mm f/1.8 Carl Zeiss Sonnar T* telephoto lens (SAL135f18z) delivers remarkable, "jaw-dropping" image quality and exceptional background separation, making it a legendary optical performer for portrait photography. Tested on a 36-megapixel full-frame Sony A7r camera via an LA-EA4 electronic lens adapter, the lens consistently produces striking, high-resolution imagery. Its fast f/1.8 maximum aperture enables an extremely shallow depth of field, perfect for isolating subjects in full-body, 3/4, and headshot poses. Built to a pro-grade standard, the lens features nine circular diaphragm blades, a 77mm filter thread, and a minimum focus distance of approximately 71.93 cm. Despite its stellar optical performance, the lens has notable drawbacks stemming from its older design and high cost. It is priced at approximately $1,800 USD, which is quite expensive considering it relies on an older, slower autofocus motor technology rather than a modern SSM focus drive. Because of this sluggish focus response, the lens is not recommended for high-speed sports photography. Additionally, because it is a native A-mount lens, mirrorless shooters must purchase a separate adapter to use it on newer E-mount...

The Zeiss Sonnar T* 135mm f/1.8 ZA (Sony SAL-135F18Z) is an all-new full-format lens designed primarily for portrait photography. The review highlights its excellent build quality, utilizing a premium all-metal construction and an internal focusing design that keeps the front element stationary. Optically, the lens benefits from an f/1.8 speed—making it the fastest 135mm autofocus lens on the market at the time—and incorporates two extra-low dispersion (ED) glass elements. Additionally, it features a decoupled focus ring that remains stationary during autofocus and a useful focus stop button. However, the review points out several significant drawbacks, particularly concerning the lens mechanics and weather protection. It lacks any seals against dust and humidity, a missing feature that should be standard for its price tier. The autofocus performance is hindered by an outdated, screw-driven camera connection rather than a quiet supersonic motor (SSM), leading to a moderate amount of operational noise. Due to the sheer weight of the heavy glass elements (1050 g), the autofocus speed is only adequate but not particularly fast. Lastly, manual focusing suffers from a slight play when changing...

The Zeiss Sonnar T 135mm f/1.8 ZA (Sony SAL-135F18Z)* is an all-new full-frame portrait lens design featuring an 11-element optical construction with 2x ED elements and 9 rounded aperture blades. Reviewed by Klaus Schroiff on an APS-C camera, it provides a 202.5mm full-frame equivalent focal length, making it highly effective for isolating objects from their environment despite requiring a longer camera-to-subject distance than normal. The lens boasts an excellent all-metal build quality, an internal focusing (IF) design that prevents the front element and 77mm filter thread from rotating, and a focus ring that decouples during autofocus. Additionally, it features a highly functional non-extending barrel, a very short minimum focus distance of 0.72m (1:4 magnification), and a built-in focus stop button. However, the review highlights several notable drawbacks, particularly regarding its mechanical operations and lack of environmental protection. The lens completely lacks dust and humidity seals, which is criticized as a major omission for its price class. Mechanically, its autofocus relies on an outdated classic screw-driven drive system powered by the camera body rather than Sony’s modern, quiet supersonic motor (SSM)....

The Photo Review assessment of the Sony SAL135F18Z 135mm f/1.8 Sonnar T* lens highlights its exceptional brightness, superior build quality, and excellent bokeh created by a nine-blade circular aperture, making it ideal for portraiture and low-light. It features fast, accurate autofocus, an efficient internal focusing mechanism, and effective Zeiss T* multi-layer coatings that control flare, ghosting, and lateral chromatic aberration. Photo Review
