Canon RF 10 20mm F 4 L IS STM Recensie | 54 Gegevens vergelijking

The Canon RF 10-20mm F4 L IS STM lens is identified as the widest rectilinear full-frame zoom ever created, offering a massive 130-degree ultra-wide focal range suitable for landscapes and architecture. The review praises its compact, lightweight design (half the weight of its predecessor), professional L-series weather sealing, and excellent center sharpness with fast STM autofocus. Conversely, the lens requires in-camera digital correction to fix significant barrel distortion and vignetting at 10mm, and the bulbous front element lacks a standard filter thread, requiring a rear gelatin filter slot. While offering f/4 constant aperture, the extreme perspective limits its use for isolating subjects or traditional bokeh-rich photography.

The Canon RF 10-20mm f/4L IS STM is a groundbreaking, ultra-wide rectilinear zoom lens designed for full-frame mirrorless cameras, replacing the older EF 11-24mm f/4L DSLR lens. It stands out as the world's first rectilinear zoom lens to reach a 10mm focal length with autofocus. By utilizing the short flange distance of the RF mount, Canon slashed the weight by over 50% down to 570g and reduced the overall footprint by 35%, making it vastly more portable and highly balanced for gimbal or drone video use. Key technical highlights include a quiet stepping motor (STM) with a fast positioning sensor, a programmable Control Ring, a custom button, and 5-stop optical image stabilization that pushes to 6 stops with IBIS. It also debuts Peripheral Control IS algorithm tech to eliminate corner "Jell-O" wobble in video. Performance-wise, the lens delivers incredible center sharpness across all focal lengths, outperforming its predecessor in edge clarity and effectively keeping vertical architectural lines straight. The review underscores several distinct pros and cons that define the lens's value proposition. On the positive side, it is highly portable,...

The Canon RF 10-20mm f/4 L IS STM is a compact, lightweight, and weather-sealed ultra-wide zoom lens that delivers professional-grade build quality with smooth control rings and a customizable front ring. Optically, it provides outstanding center sharpness and excellent near-center resolution across its entire zoom range at f/4, even outperforming traditional expectations at the 14mm and 20mm focal lengths. Its stepping motor (STM) autofocus is fast and essentially silent, while its optical image stabilizer offers an impressive 5 f-stops of stabilization (up to 6 stops when paired with in-camera IS), making it highly capable for indoor and low-light photography. Additionally, lateral chromatic aberrations are remarkably well-controlled, and the lens produces pleasing sun-stars when stopped down. On the downside, the lens is a technically under-designed optic that relies heavily on digital auto-correction to mask extreme flaws. In uncorrected RAW images, it suffers from a massive 9.2% barrel distortion and black corners due to extreme 12-stop vignetting at the 10mm setting. Flare performance is also a mixed bag; while minimal in ideal conditions, recomposing can cause very obvious color artifacts and ghosting...

The Canon RF 10-20mm f/4L IS STM is an ultra-wide zoom lens praised for its incredibly compact, lightweight design, weighing just 570 grams—less than half its EF predecessor. It delivers a massive 130-degree diagonal field of view at 10mm, making it highly effective for real estate, architecture, and night sky photography. Key benefits highlighted in the review include up to six stops of image stabilization, silent STM autofocus, excellent resistance to lens flares, and almost no coma distortion in the corners, which keeps stars crisp. Additionally, it features a programmable button, a control ring, and a rear gelatin filter holder. However, the lens relies entirely on intensive in-camera lens correction to mask severe barrel distortion and vignetting, particularly at the 10mm focal length. This electronic correction forces a trade-off, resulting in reduced image sharpness and soft details in the extreme corners unless the lens is stopped down. Furthermore, the physical shape of the bulging front element makes it impossible to use standard 100mm front filter systems, requiring expensive adapters or specialized 150mm setups instead. Users must also carefully manage the...

The Canon RF 10-20mm f/4 L IS STM is a highly portable, full-frame ultra-wide-angle zoom lens designed for RF-mount cameras like the EOS R5. A major standout feature is its remarkably lightweight and compact design, weighing only 0.57 kg compared to the much bulkier 1.18 kg EF-mount equivalent. It features built-in optical image stabilization that enables sharp handheld low-light photography and steady video tracking, while its silent STM autofocus is smooth and reliable for video recording. Additionally, despite its premium build, it performs admirably for its price class and costs roughly $700 less than older EF counterparts. However, the lens does come with several distinct physical and structural drawbacks. It completely lacks a front filter thread, requiring a dust cloth for spot cleans and forcing users to rely entirely on a rear gelatin filter slot. Its front element acts as a persistent dust and oil magnet, making it exceptionally difficult to keep clean. Handling is slightly compromised because the focus and control rings are placed too close together, leading to accidental adjustments, and its unusually thick 1-inch lens cap is...

The review highlights several critical pros and cons to consider before buying. On the positive side, it stands out as the widest zoom lens currently available, offering incredible optical performance in a remarkably compact and travel-friendly form factor. On the negative side, the lens relies heavily on digital software corrections to mask strong barrel distortion and corner cropping. Furthermore, it suffers from limited versatility with a maximum focal length of only 20mm, and its hefty $2,299 price tag makes it a significant investment.

The Canon RF 10-20mm f/4L IS STM lens, reviewed by Photo Review Australia, is a compact, lightweight ultra-wide zoom designed for travel, featuring a constant f/4 aperture, robust weather-sealing, and built-in image stabilization. The RF mount technology delivers superior optical performance, producing extremely flare-free images even with direct light sources in the frame. Photo Review However, the lens is still relatively large for its class and exhibits noticeable distortion, requiring users to stop down for maximum sharpness. Additionally, the bulbous front element prevents the use of standard screw-in filters, limiting protective options to the lens cap.

The Canon RF 10-20mm f/4 L is the world's first autofocusing, rectilinear, full-frame ultra-wide zoom lens, priced at $2,299. This lens serves as a much smaller and lighter replacement for the older adapted EF 11-24mm f/4 L, weighing just 20 ounces (570 grams) while keeping a rugged, fully weather-sealed construction. Its standout pro features include an optical image stabilization unit that offers up to six stops of shake control on IBIS-equipped bodies, a customizable control ring and barrel button, and a silent, fast stepping motor (STM) autofocus system. Optically, it excels by delivering excellent, consistent sharpness from the center all the way into the corners even when shooting wide open at f/4, making it highly effective for landscape and cityscape photographers looking to maximize high-resolution sensors like the 45-megapixel EOS R5. However, the review highlights several distinct cons and design tradeoffs. Due to its bulbous front element, the lens features an integrated hood that completely prevents the use of front-mounted filter threads, relying instead on a rear-element filter holder. While the lens handles flare remarkably well and produces beautiful, long-pointed...
