Score: 66/100
Yongnuo YN50mm F1.8 Canon
Score: 70/100Rankings
The Yongnuo YN50mm f/1.8 for Canon EF is an affordable, lightweight prime offering a fast aperture and decent optics. It excels in portability and price-to-performance but lacks weather sealing and has a noisy autofocus motor.
The Sigma 70-300mm f/4-5.6 DG Macro offers an affordable telephoto zoom with a 1:2 macro capability, suitable for full-frame and APS-C DSLRs. While it provides decent sharpness at shorter focal lengths, it suffers from softness at the long end, vignetting, and lacks image stabilization.

Professional reviewers praise the lens for its sharpness at the wide end and mid-range, the inclusion of SLD glass, and the rare 1:2 macro capability at an entry-level price. However, they consistently note corner softness at full telephoto, noticeable vignetting on full-frame, slow autofocus and the absence of stabilization, making it more of a walk-around lens than a professional workhorse.
Everyday users love the macro function, the reach for wildlife and travel, and the reliable performance of the built-in motor on Nikon entry-level DSLRs. Common complaints revolve around softness at the long end, autofocus hunting, occasional internal haze, and the lack of image stabilization, but most owners consider the lens a durable, good-value tool for hobbyist photography.
