Sigma 300mm F2 8 EX APO DG HSM Review | 54 Data compared

This Sigma 300mm f/2.8 lens offers a budget-friendly option for sports and wildlife photographers, standing out for its excellent distortion-free imaging and minimal wide-open vignetting on sub-frame cameras. It is solidly built with a robust metal and plastic construction, featuring a smooth, 180-degree manual focus ring, a convenient rotating drop-in 46mm filter system, and near-silent HSM autofocus on Canon, Nikon, and Sigma mounts. On a sub-frame body, the lens delivers a practical 450mm to 480mm equivalent field-of-view. However, the lens has notable drawbacks, as it fails to reach tack-sharpness at any aperture setting and exhibits higher chromatic aberration that worsens when stopped down. Full-frame camera users will also experience soft corners—especially between f/2.8 and f/8—along with noticeable 3/4-stop corner shading when wide open. Additionally, it lacks advanced modern features like image stabilization, focus limiting, and memory options found on pricier Canon or Nikon rivals, while Pentax and Sony users are restricted to slower, mechanical autofocus.

The LensTip review of the Sigma 300 mm f/2.8 EX DG HSM APO highlights it as a highly capable and exceptionally well-made journalistic lens that serves as a budget-friendly alternative to native camera brands. Priced significantly lower than its direct competitors from Canon, Nikon, Sony, and Olympus, this telephoto lens delivers impressive optical performance despite lacking built-in image stabilization. Its robust physical build is constructed from a solid metal alloy typical of Sigma's premium EX line, featuring a large, comfortable manual focus ring and an internal focusing mechanism that keeps the lens's physical length constant. Furthermore, it includes a generous accessory bundle such as a hard case, lens hood, tripod adapter, and a rotatable drop-in polarizing filter holder. Optically, the lens boasts numerous advantages, including excellent image resolution at the frame center across all aperture settings, good resolution at the frame edges, and highly effective control over distortion and coma. It also handles bright, direct light exceptionally well with minimal flare or contrast degradation, and exhibits moderate vignetting that completely resolves when stepped down to f/4.0. However, the review notes...

The ⁠LensTip review concludes that the Sigma 300 mm f/2.8 EX DG HSM APO is an exceptionally well-made lens that offers an excellent value-to-performance ratio, costing roughly half as much as its direct proprietary competitors. Tested on a Canon 20D body, the lens delivers standout optical performance standalone. Its core pros include very good image resolution in the frame center across all apertures, comfortably exceeding the 30 lpmm usability threshold even when shot wide open at f/2.8. Additionally, it provides solid frame edge resolution, well-controlled coma, virtually zero geometric distortion, and minimal vignetting on APS-C sensors. The lens barrel boasts a very solid, professional EX-series build quality and incorporates a silent and smooth Hyper Sonic Motor (HSM) for focusing. However, the lens suffers from notable drawbacks when paired with additional gear or pushed to extremes. The primary optical con is the significant decrease in image quality after attaching the 1.4x APO teleconverter. When using the teleconverter, the maximum relative aperture becomes far from useful, and the frame edge resolution drops sharply to a very weak level. Chromatic aberration also presents...

The Sigma 300 mm f/2.8 EX DG HSM APO is a highly solid, well-built telephoto lens that stands out as the most affordable option in its class while maintaining impressive optical performance. Its primary strengths include excellent image quality in the frame centre across all apertures, good edge quality, well-controlled chromatic aberration, and almost zero distortion. Additionally, the lens features a quiet, rapid autofocus system and handles bright backlighting effectively. Buyers also benefit from a generous accessory kit containing a lens hood, tripod adapter, hard case, and polarizing filter, alongside a long base warranty that can be extended up to five years. However, the lens has notable drawbacks, most critically the complete absence of image stabilization, requiring high shutter speeds of 1/500 second or faster for handheld shooting. While its fast f/2.8 aperture offers great shooting comfort, the extremely thin depth of field easily exposes slips in its autofocus accuracy, which could be better. Furthermore, using a teleconverter causes a significant decrease in image sharpness, though stopping the lens down by a single stop helps recover useful photo quality. Ultimately,...

The Sigma 300mm f/2.8 APO EX DG is a professional-grade, durable telephoto lens offering high-contrast, sharp images at f/2.8, particularly regarded for its superior build quality and performance with teleconverters. While offering great value, the lens is heavy, relies on noisy, slow screw-drive autofocus on Pentax, and features a non-standard focus ring direction.

Here is a specific summary of the Sigma 300/2.8 HSM EX telephoto lens review: This review highlights the Sigma 300/2.8 HSM EX as an excellent, budget-friendly alternative to premium "big glass" lenses from major brands like Canon and Nikon, offering savings of 30 to 40 per cent. Built with a lightweight metal alloy barrel and a matte black finish, the lens boasts superb ergonomics. Pros include a highly secure, smooth-turning tripod collar and a beautifully damped manual focus ring that outshine Canon's 300/4L equivalent. Optically, it delivers fantastic sharpness, smooth background bokeh, and great contrast with minimal flare. Furthermore, its HyperSonic Motor (HSM) provides fast, silent autofocus that curiously maintains its snappy speed even when paired with 1.4x and 2x teleconverters. However, the reviewer notes a few definitive cons when comparing it to top-tier competitor lenses. The most notable omission is the lack of image stabilization (IS) technology, which is standard on Canon's $5,000 equivalent. Ergonomically, the lens oddly lacks a focus range limiting switch, which is a common "bell and whistle" found on rival hardware. Additionally, while results remain...
