Sigma 70 300mm F4 5 6 DG Macro Review | 54 Data compared

The reviewed Sigma 70-300mm F4-5.6 DG Macro lens is a budget-friendly option priced under €150, making it an appealing choice for beginners on entry-level camera bodies. Key advantages include its compact, lightweight design, and a highly versatile zoom range coupled with a functional proxy-macro mode that delivers a 0.5x magnification ratio. Additionally, its common 58mm filter diameter makes purchasing extra filters highly affordable, and the lens conveniently includes a lens hood right out of the box. However, the reviewer highlights several prominent drawbacks, most notably a total lack of optical or electronic image stabilization, making it difficult to use at long focal lengths or in low-light environments. The autofocus is painfully slow and often fails to lock onto moving objects altogether, while the lens body itself easily attracts dust and sand. Optically, it struggles with frequent chromatic aberrations in high-contrast lighting. Its limited optical resolution also results in a severe, "catastrophic" drop in sharpness on any modern camera sensor exceeding 14 to 15 megapixels.

The Radojuva review of the Sigma 70-300mm 1:4-5.6 characterizes this full-frame telephoto lens as an incredibly low-cost, budget-friendly option for amateur photographers. Key positives include its highly accessible price, built-in micro-motor for autofocus on entry-level cameras, and a specialized Macro switch offering a 1:2 magnification ratio. Conversely, major cons include a rotating and telescoping front element that complicates filter use, slow and noisy autofocus, and severe "focus breathing". Additionally, image quality degrades significantly past 200mm, requiring users to stop down the aperture to achieve adequate sharpness at 300mm.

The Sigma 70-300mm f/4-5.6 APO DG MACRO is a budget-friendly telephoto zoom lens tested on a full-frame Pentax K-1 camera, though it is also fully compatible with APS-C sensor bodies where it provides a 105-450mm equivalent focal range. Priced at an affordable €169, it stands out for its integrated macro switch that delivers a 1:2 magnification ratio between the 200mm and 300mm focal lengths, turning it into a highly capable option for close-up proxi-photography. Optically, the lens delivers impressively minimal distortion across its entire zoom spectrum and produces good overall image sharpness and contrast up to 200mm, heavily aided by its apochromatic (APO) glass design. Handling is also a notable plus, as the lens is lightweight at under 550g and features a smooth, wide zoom ring alongside a sturdy metal lens mount. However, the reviewer highlights several drawbacks, particularly its slow, variable maximum aperture that drops to f/5.6 at 300mm, making autofocus unreliable in low-light environments and limiting its usefulness for serious wildlife photography. Because it relies on the camera body's screw-drive mechanism for autofocus, the operation is remarkably noisy....
