Professional reviewers describe the EF 75-300mm f/4-5.6 III as Canon's basic, budget-friendly long zoom. They commend its ultra-light weight and compact form factor, but repeatedly note the sluggish micro-motor autofocus, modest build quality, and average optical performance, especially the softness and reduced contrast at the 300 mm end.
Everyday users love the lens for its portability and inexpensive telephoto reach, often mentioning how easy it is to pack for travel and wildlife outings. However, they commonly complain about the slow, noisy autofocus, the absence of stabilization, plastic feel, and noticeable softness at the long end, which detracts from image quality in low-light or high-magnification scenarios.
Professional reviewers commend the Sigma 16mm f/1.4 for its impressive center sharpness, bright aperture and quiet stepping AF, calling it a high-value option for Sony APS-C shooters. They note that while the lens excels in low-light and offers smooth bokeh, its corner performance at f/1.4 and occasional AF hunting in dim conditions are drawbacks, though in-camera distortion correction mitigates barrel distortion.
Everyday users generally praise the lens for its sharp images, pleasing bokeh, compact build and reliable AF in good light, appreciating the weather-sealed design for outdoor use. Recurring complaints focus on soft corners when wide open, AF inconsistency in low-light or close-up scenarios, and the lens being a bit bulkier than ultra-compact alternatives.
