Yongnuo Yn 50mm F 1 8 II Análisis | 54 Datos comparados

The Yongnuo YN50mm f/1.8 II is a highly affordable "nifty fifty" lens designed specifically for Canon DSLR systems, serving as a direct budget alternative to first-party options. Priced at just £53, it costs less than half the price of the Canon 50mm f/1.8 STM. Notable pros highlighted in the review include its highly compact and lightweight design, coupled with a solid barrel build and a metal mounting plate, which is a rare premium feature for an entry-level budget lens. Optically, it scores well by matching the sharpness of its Canon counterpart at most apertures, showing massive sharpness gains when stopped down to f/2.5, and peaking between f/8 and f/11. Furthermore, its 7-blade aperture iris delivers excellent bokeh effects, its 58mm filter thread matches standard 18-55mm kit lenses, and the front lens section does not rotate during autofocusing, making it very user-friendly for physical polarising or ND filters. Conversely, the review notes several clear cons that buyers should consider before purchasing. The autofocus mechanism lacks the ultra-quiet USM or STM motors found in native Canon lenses, making the operation noisier and...

The Yongnuo YN50mm F1.8 (Mark I) is a budget-friendly clone of the iconic Canon EF 50mm f/1.8 II lens that delivers a mixed experience for shooters. On the positive side, the lens matches the original Canon optics closely in terms of image quality and is priced lower than Canon’s newer STM equivalent, making it an attractive, low-cost option for digital SLR users. However, it feels cheaply built out of plastic, includes a plastic mount plate, and suffers from autofocus performance that is slightly slower than the original Canon lens. The biggest drawback highlighted in the review is the lens's severe firmware compatibility issues with older Canon EOS film bodies. Due to reverse-engineered firmware that lacks a proper communication handshake with older cameras, the lens causes most pre-2000 consumer film models—such as the EOS 100, 300, 500, and 650—to experience immediate mirror lock-ups and flashing low-battery errors upon pressing the shutter button. While it does work successfully with a select few film bodies like the EOS 5, 300X, and 3000V, the shrinking price gap between a new Yongnuo and a reliable,...
