Canon EF 28mm F 2 8 IS USM Análisis | 54 Datos comparados

The Canon EF 28mm f/2.8 IS USM is a premium-tier, non-L wide-angle prime characterized by exceptional sharpness across the frame from f/2.8, becoming critically sharp by f/4. It features highly effective 4-stop image stabilization, quick AF performance, and remarkably well-controlled flare compared to its predecessor. However, the lens exhibits strong peripheral shading (up to 3 stops at f/2.8 on full-frame) and noticeable corner lateral chromatic aberration. Additionally, the AF is audible in quiet settings, the price is steep for an f/2.8 optic, and it lacks included accessories like a hood.

The ePHOTOzine review highlights the Canon EF 28mm f/2.8 IS USM as a lightweight (260g), high-quality prime lens featuring effective 4-stop optical image stabilization and fast, quiet USM autofocus. It delivers excellent sharpness and low distortion, making it ideal for various applications. Conversely, the review notes a relatively slow f/2.8 maximum aperture for its price point and significant vignetting at that setting. Additionally, the lens does not include a hood or case, representing an added expense for the user.

The Canon EF 28mm f/2.8 IS USM is a compact, lightweight prime lens that delivers exceptionally sharp optical performance and ranks as a top-tier wide-angle option for Canon shooters. Testing reveals remarkable consistency across the frame, highly effective control over chromatic aberration, and very low levels of geometric distortion. Its standout features include a fast, reliable Ultrasonic Motor (USM) autofocus system and a 4-stop image stabilization system, which successfully compensates for low-light shooting despite the lens's modest maximum aperture. Additionally, it easily outperforms older alternatives like the Canon 28mm f/1.8 in sharpness, and matches the optical quality of premium, manual-focus rivals like the Carl Zeiss Distagon 28mm f/2 at a fraction of the cost. However, the lens does present a few notable drawbacks. It suffers from heavy vignetting of nearly two stops when shot wide open at f/2.8, though this dark cornering quickly disappears as the aperture is stepped down. Its overall resolution and sharpness also experience a noticeable drop-off when shooting at very small apertures due to diffraction. Finally, the maximum aperture of f/2.8 limits its capacity for creating...

According to Ken Rockwell, the Canon EF 28mm f/2.8 IS USM is an optically superb, lightweight lens featuring exceptional sharpness, even when shot wide-open, and fast, near-silent autofocus. It provides effective image stabilization and precise manual focus override, making it a high-performance choice for full-frame cameras. However, the review notes minor mechanical, internal rattling sounds during autofocus, and it lacks the wider f/1.8 aperture necessary for capturing better sunstars and faster shutter speeds in low light. While the stabilization enhances handheld shooting for still subjects, it cannot stop subject movement.

The DPReview article on the Canon 28mm F2.8 IS USM highlights the lens as an exceptionally lightweight and compact travel option for full-frame cameras, offering a dense, durable build with a metal mount and rubberized focus ring. Key performance advantages include effective image stabilization, a fast USM autofocus motor, and notable durability during coastal use. However, the lens faces drawbacks, including a high $499 MSRP, a lack of weather sealing, and noticeable green/purple chromatic fringing that requires post-processing correction. While optically capable, it is described as not exceptionally sharp on high-resolution sensors and possesses a slight internal rattle when powered off.

The Photozone / OpticalLimits review introduces the Canon EF 28mm f/2.8 USM IS as the 2012 successor to a 25-year-old classic EOS prime lens, keeping the same focal length and speed while integrating significant mechanical upgrades. Built with a metal mount and high-quality plastics, this full-format lens weighs a lightweight 260 grams and features a 58 mm non-rotating filter thread. Pros highlighted in the review include its ring-type Ultrasonic (USM) autofocus drive, which delivers very fast and virtually silent focusing alongside full-time manual focusing (FTM) support. Additionally, its physical body length remains completely constant across all focus settings, effectively minimizing vulnerable entry spaces for dust and moisture despite lacking official weather-sealing. The core performance boost comes from its new optical image stabilizer (IS), which elevates its utility for hand-held indoor, low-light, and street photography over bulky zoom lenses. Despite these performance upgrades, the lens comes with notable downsides and cons. While Canon officially rates the integrated optical stabilizer for a 4-stop advantage, the reviewer states that in real-world scenarios, it is better to take this claim with a grain of...

The Canon EF 28 mm f/2.8 IS USM prime lens delivers excellent general performance highlighted by its highly efficient image stabilization system, which provides up to 4 EV of correction. In terms of pros, the lens boasts very good sharpness in the center of the frame (reaching values over 40 lpmm wide open), negligible astigmatism, and low coma on APS-C sensors. Additionally, it features a very swift and accurate USM autofocus motor, handles bright light well with minimal ghosting or flares, and displays excellent optical properties across smaller sensor bodies. However, the lens suffers from notable flaws when paired with a full-frame sensor. The primary cons include weak image quality on the full-frame edge when shooting at the maximum f/2.8 aperture, coupled with high coma in the extreme corners of a full-frame detector. Photographers will also have to contend with huge vignetting on full frame, and the lens ships with a somewhat modest accessory kit for its price tier. LensTip.com
