Verdict

The Canon EF 50mm f/1.8 STM is a compact and lightweight prime lens weighing 160g, featuring an optical design of 6 elements in 5 groups, a 49mm filter thread, and a circular 7-blade aperture with a minimum focusing distance of 0.35m. Key advantages include its bright f/1.8 maximum aperture for excellent low-light performance and beautiful bokeh, sharp central image quality, an upgraded metal mount for better durability, and a smooth gear-type Stepper Motor (STM) for quiet autofocus during video recording. However, it exhibits noticeable corner softness and vignetting when wide open at f/1.8, lacks built-in image stabilization, and omits weather-sealing protectivity.

Canon EF 50mm f/1.8 STM Lens Review

The Canon EF 50mm f/1.8 STM is identified as a significant upgrade over its predecessor, offering superior build quality with a metal mount, faster and more accurate autofocus, and better bokeh. It delivers excellent center sharpness at f/1.8, with edge-to-edge clarity improving by f/4. Key disadvantages noted include noticeable corner softness on full-frame cameras at wide apertures, along with pronounced vignetting at f/1.8 that persists until f/2.8. Additionally, the autofocus produces a slight, audible whine, and the lens lacks both weather sealing and image stabilization.

Canon EF 50mm F1.8 STM lens review: Thrifty fifty

The Canon EF 50mm F1.8 STM is a budget-friendly entry-level prime lens that replaces the older Mark II version while retaining the same 6-element, 5-group optical formula. Key advantages of this updated model include its improved build quality with a metal mount, closer minimum focusing distance of 13.78 inches (35cm), and Super Spectra Coating to minimize ghosting and flare. Additionally, it features a circular 7-bladed aperture and a stepper (STM) motor for quieter, smoother autofocus, making it highly useful for video recording. Optically, the lens delivers strong center sharpness, lower distortion, and reduced chromatic aberration that drops to just 4 microns, offering a performance that rivals more expensive lenses like the Canon f/1.4 when stopped down to f/2.8. Despite these enhancements, the lens carries a few notable drawbacks. Performance at wide apertures is only average near the edges, and the outer field shows a measurable loss of acutance compared to its predecessor. Furthermore, vignetting is higher than expected, peaking at –2.5Ev in the extreme corners. The exterior also continues to lack a focus distance window and markings. However, considering its...

Canon EF 50mm f/1.8 STM Astrophotography Review

Ian Norman’s review on Lonely Speck highlights the Canon EF 50mm f/1.8 STM as a highly affordable ($125) entry-level prime, making it an excellent budget option for deep-sky and panorama night photography. Key advantages include its lightweight, compact design, a durable metal mount, and a smooth, "focus-by-wire" manual ring that, when stopped down, produces high-resolution images suitable for mosaics. However, the lens has significant limitations, as wide-open performance at f/1.8 suffers from heavy optical aberrations, low contrast, and severe coma distortion, particularly in the corners of a full-frame sensor. To achieve optimal sharpness, photographers must stop down to f/2.8, which reduces light-gathering capability and, due to its 50mm focal length, requires a more complex tracking or panorama workflow.

The Canon EF 50mm f/1.8 STM is a highly affordable, lightweight 160g prime lens that delivers outstanding value and optical quality, easily outperforming the older, pricier Canon EF 50mm f/1.4 USM lens in sharpness—particularly between f/1.8 and f/2.8. This updated version features a quiet, speedy stepping motor (STM) system that prevents the focus ring from rotating during use, a sturdy metal mounting plate, and a 7-blade diaphragm that creates beautifully rounded bokeh compared to the pentagonal highlights of previous models. It also boasts excellent edge-to-edge sharpness on APS-C bodies, minimal color fringing, and a deeply recessed front element that reduces the necessity of a lens hood.

Summary of the review

Canon EF 50mm F/1.8 STM Review

The Canon EF 50mm f/1.8 STM is a highly recommended prime lens that offers substantial upgrades over its predecessor, the 50mm f/1.8 II, making it an excellent first choice after a standard kit lens. A key strength of the lens is its improved build quality, featuring a robust metal bayonet instead of plastic and a durable, slightly roughened exterior that eliminates any previous rattling. The transition to a Stepper Motor (STM) makes the autofocus much quieter and better suited for video recording, while simultaneously lowering the rate of missed-focus shots. Additionally, image quality has significantly advanced, providing usable sharpness even at wider apertures like f/2.0 and exceptional clarity starting at f/2.8. Thanks to the inclusion of 7 circular aperture blades instead of 5, the lens produces a much softer, smoother background bokeh without geometric artifacts. It is compatible with nearly all analog and digital Canon EOS cameras across both APS-C and full-frame formats. Despite these advantages, the review highlights a few limitations to consider before purchasing. While its overall sharpness is commendable, the lens is still somewhat soft when shot...

Summary of the review

Canon EF 50mm f/1.8 STM Review

The Canon EF 50mm f/1.8 STM is a highly capable and affordable prime lens that offers significant upgrades over its predecessor, the EF 50mm f/1.8 II. Structurally, Canon replaced the old fragile plastic mount with a more durable metal lens mount to reduce wear during lens changes. The exterior features a tight, matte black plastic finish with a smooth 1/4-inch electronic focus-by-wire ring that rotates 180 degrees, drastically improving manual focus control. Optically, the lens punches well above its $125 price point, incorporating Super Spectra Coating (SSC) to improve light transmission and minimize flare. It is highly praised for its exceptional sharpness, minimal sample-to-sample manufacturing variation, and remarkably low chromatic aberration. Despite its high value, the review outlines several notable downsides, particularly regarding video usage and specific optical distortions. The electronic focus-by-wire system lacks a direct physical connection, which results in an inconsistent relationship between the focus ring and the focus position. This makes it difficult to use with standard follow-focus gears or to perform rapid snap-focus adjustments during video recording. Optically, the lens suffers from heavy vignetting that peaks...

Canon EF 50 mm f/1.8 STM review - Introduction

The LensTip review of the Canon EF 50 mm f/1.8 STM evaluates the 2015 successor to the iconic, 25-year-old plastic Mk II "nifty fifty" prime lens. While the optical elements remain identical at 6 elements in 5 groups, LensTip highlights massive improvements in physical construction and functionality. The prominent pros of this upgraded version include its excellent image quality in the frame center (reaching an impressive peak resolution of 45.9 lpmm at f/4.0), decent edge-of-frame sharpness, and highly controlled chromatic aberration. Furthermore, it introduces a durable metal lens mount, a genuinely usable manual focus ring, a shorter minimum focusing distance of 35 cm, and a quiet, highly accurate STM autofocus motor. Combined with an upgraded 7-blade aperture design for smoother bokeh, it offers a legendary price-to-quality ratio. However, the review details notable cons stemming from its unchanged, legacy optical formulation. The most severe drawback is a monstrous level of coma in the corners of full-frame sensors, requiring photographers to stop down the lens by at least two full stops (2 EV) to mitigate the aberration. Additionally, full-frame users face heavy...

Canon EF 50mm F1.8 STM real-world samples gallery The-Digital-Picture.com

The Canon EF 50mm F1.8 STM, as showcased in the DPReview gallery, is an affordable prime lens featuring improved build quality with a sturdy metal mount and a 7-blade rounded aperture for better bokeh. It delivers excellent center sharpness, particularly when stopped down, and uses a Stepper Motor (STM) for improved autofocus performance. Conversely, the lens exhibits soft corner performance and heavy vignetting when shooting wide open at f/1.8 on full-frame cameras, and it lacks built-in image stabilization. While the STM motor is improved, it is not completely silent, and the lens represents a budget-conscious compromise in overall optical performance compared to higher-end glass.

The 'New' Canon EF 50mm 1.8 STM

The Canon EF 50mm f/1.8 STM is a highly recommended, budget-friendly prime lens that transforms basic kit cameras into "bokeh wonders" due to its wide maximum aperture. The reviewer notes several prominent pros, starting with the updated STM focus motor, which is significantly faster and noticeably quieter than its predecessor. Optically, the lens delivers a minor boost in sharpness, a beautiful, butter-smooth portrait look, and drastically improved control over chromatic aberrations (CAs) when shooting into backlighting. Additionally, its soft, blending lens flares are praised for looking more natural and integrated into the image compared to the harsh flares found in pricier alternatives like the Sigma 50mm. At approximately €130, it remains highly affordable while upgrading to a sturdier metal lens mount. However, the review details a few notable cons and design drawbacks. A major complaint is that the autofocus accuracy has not improved, meaning users will still encounter frustrating focus misses when shooting wide open at f/1.8. The physical design changes also present a hassle, as the filter thread size dropped from 52mm to 49mm, forcing users with old accessories...

Is the EF 50mm f/1.8 STM really a lemon on the R7?

The user "wildtapir" conducted a real-world test to determine if the older, budget-friendly Canon EF 50mm f/1.8 STM lens performs poorly ("eine Gurke") when mounted via an adapter on the modern, high-pixel-density APS-C Canon EOS R7 camera. In a controlled living room setup using a tripod and electronic shutter, the reviewer compared 100% center crops at wide-open aperture against the modern, highly-regarded RF 35mm f/1.8 lens, ensuring an identical reproduction scale. To the reviewer's surprise, center sharpness and contrast on the EF 50mm were exceptional, even slightly edging out the RF 35mm in the absolute image center. Other forum members chimed in to support these findings, noting that while it is an inexpensive "plastic fantastic" prime lens, it has historically outperformed the pricier EF 50mm f/1.4 USM in general recommendations and remains a highly capable, ultra-compact option for travel. However, the review and subsequent forum discussion highlight several distinct optical and physical limitations when using the lens wide open. Testing at the edges of the APS-C sensor revealed noticeable weaknesses in edge contrast and sharpness, proving that the lens requires...

Canon EF 50mm f/1.8 STM Review: My First Prime Lens

The Canon EF 50 mm f/1.8 STM is a highly affordable, compact, and lightweight prime lens that serves as an excellent learning tool for novice photographers. Weighing just 159 grams and measuring under 4 cm in length, it features a solid metal bayonet mount and a smooth manual focus ring. A key upgrade is its step-by-step STM autofocus motor, which delivers fast, silent, and fluid performance well-suited for video recording. Its bright f/1.8 maximum aperture allows for great low-light performance and offers creative control over depth of field, enabling users to easily isolate subjects with a smooth background blur. When paired with an APS-C sensor camera, it converts into a highly effective 80mm equivalent portrait lens. However, the lens has notable limitations, particularly regarding image sharpness, which remains too soft from its widest aperture up to f/4. The images also lack uniformity at large apertures, showing a sharp center but very soft edges, though closing the aperture down to f/8 yields highly detailed results across the entire frame. Additionally, the lens lacks optical image stabilization, making it prone to camera...

Canon 50mm f/1.8 STM Review

This review examines the Canon EF 50mm f/1.8 STM lens, featuring insights from a video comparison by Chris Lavigne against its predecessor and the Sigma 50mm f/1.4 ART. The main takeaway is a strong recommendation to purchase this lens if you do not already own a 50mm model. The reviewer explicitly advises against buying the older version to save a small amount of money, emphasizing that the architectural and operational upgrades found in the STM version make it a far superior choice. The lens's primary advantage is its upgraded stepping motor (STM), which provides a significantly smoother and quieter autofocus experience compared to the frustratingly loud mechanism of the original version. However, the review and user comments highlight a few limitations. While the autofocus is a major upgrade over the older model, some users note it still produces a plasticky noise that is noticeably louder than premium video lenses like the Canon 18-135mm IS STM. Additionally, when using continuous video autofocus in low-contrast environments, the focus mechanism has a tendency to hunt ("patine"), requiring a switch to manual or single-point...

Canon 50mm f/1.8 STM – Opinions on an Essential Lens

The Canon 50mm f/1.8 STM, nicknamed the "Ninty Fifty," is widely considered an essential, budget-friendly prime lens for both amateur and passionate photographers. When tested on an APS-C sensor (like the Canon EOS 80D), it delivers an 80mm equivalent focal length, making it an excellent and highly satisfying tool for portrait photography due to its ability to capture rich facial details and create a three-dimensional effect. Its standout advantages are its ultra-lightweight build (159 grams) and highly compact dimensions (69x39mm), which make it an ideal choice for travel. Additionally, its 7-blade circular aperture produces very soft, dreamy, and pleasing background blur (bokeh). However, this entry-level lens comes with notable compromises. It lacks image stabilization, requiring a steady hand or faster shutter speeds to prevent motion blur. While it is a "fast lens," shooting wide open at f/1.8 introduces chromatic aberration and softness at the edges, meaning users need to stop down to f/2.8 or higher to get uniform sharpness. Furthermore, the build relies on a cheap-feeling plastic material, the lens hood is not included in the box, and the stepping...

Test, de nieuwe Canon 50mm f/1,8 STM - HeelHollandFotografeert

The Canon 50mm f/1.8 STM lens features notable physical and aesthetic improvements over its predecessor, shifting from a plastic to a durable metal mount and adding a solid outer plastic finish. Performance upgrades include an aperture with 7 blades rather than 5, which significantly smooths out the background blur (bokeh) and creates rounder, visually pleasing out-of-focus light elements. The updated STM focusing motor provides quick autofocus while operating quietly, fixing the loud "coffee grinder" sound of the older version and making it much better suited for DSLR video recording. Additionally, the revised focus ring can now be manually rotated even when the lens is actively set to autofocus. Despite these benefits, the lens has a few minor drawbacks. Its physical frame requires a smaller filter diameter of 49mm compared to the previous 52mm, forcing users with existing filters to purchase a step-down adapter ring. Optically, the tester noted noticeable purple fringing in high-contrast environments and observed that the lens consistently captures images about 1/3 of a stop darker than comparable 50mm models. Canon also continues its trend of not including...

Why I am so happy with it!

This review details the author's highly positive experience with the Canon 50mm f/1.8 lens (often called the "Nifty Fifty"), which became her primary lens for over a year. The author heavily praises its capability to create a beautiful shallow depth of field, or blurry background, which makes subjects stand out dramatically in portrait, detail, and product photography. She highlights its versatility for capturing flowers, animals, and flatlays, noting that its compact, lightweight design makes it incredibly handy for everyday use and travel compared to bulky alternatives. Finally, a major selling point is its affordability, costing just over €100, which provides exceptional value for photographers on a budget. Despite her enthusiasm, the review notes a few key drawbacks. Because it is a prime lens with a fixed focal length, it lacks any zoom capability. This requires the photographer to physically move back and forth to frame a shot properly, making composition more challenging for beginners. Additionally, the lens is not ideal for landscape or architectural photography due to its narrow frame, which limits how much of a wide scene or large...

Canon EF 50mm f/1.8 STM Lens Review

The Canon EF 50mm f/1.8 STM is a highly affordable, compact, and lightweight budget lens that serves as a modern upgrade to its popular but fragile "plastic fantastic" predecessor. A major benefit of this lens is its vastly improved build quality, featuring a sturdy metal mount instead of cheap plastic, alongside a significantly quieter and smoother STM autofocus motor that pairs excellently with video tracking systems. Furthermore, its wide f/1.8 aperture allows roughly ten times more light to enter compared to a standard kit lens, making it an exceptional, budget-friendly tool for low-light situations and for capturing portraits with a beautiful, blurry background. On the downside, the lens is optically almost identical to the older version, showing no significant advancements in image performance despite a decade-long gap between models. When shooting wide open at f/1.8, users will experience corner darkness (vignetting), mediocrity regarding chromatic aberrations, and reduced sharpness when mounted on APS-C crop sensor cameras. Additionally, it completely lacks weather sealing, though the review notes this is standard for its price bracket.
