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...

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.

The.RAW Magazine review highlights the Canon EF 50mm f/1.8 STM as a budget-friendly, versatile lens featuring a durable metal mount, quiet STM autofocus, and improved bokeh from seven-curved aperture blades. While offering superior build quality and close-focusing capabilities compared to its predecessor, the lens is noted for its lack of image stabilization and slower, albeit quieter, autofocus speed.

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...

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...

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.
