Ignore the lack of acronyms and look at its performance instead: Sony’s f/1.4 has some weaknesses but elsewhere it’s a real cracker.

  Great real-world results

  AF is noisy and non-IF

Having reviewed four other 50mm F1.4 lenses of similar design over the past few months, we weren't expecting any major surprises from the Sony version. And in broad terms it's not hugely different from its Canon, Nikon and Pentax equivalents; as befits a quality prime it gives excellent image...

  Unusually good performance on APS-C even at wide apertures, Excellent image quality when stopped down on both full-frame and APS-C, Low distortion

  Very soft across most of the frame at wide apertures on full frame, Bokeh chromatic aberration, most visible at wide apertures, Vignetting at wide apertures on full frame (essentially disappears by F3.3), Corner softness on full-frame - never quite sharp even at F8, Somewhat susceptible to flare

Rich colors, super sharp, and the bokeh had me crying tears of joy. That also was not a problem because this thing is weather sealed too! At this price point, you truly get what you pay for. CZ never disappoints!

This is one of my favorite lenses, hands down. I am a professional wedding and portrait photographer, and I use this more than 50% of the time. The Zeiss opticals truly set this lens apart, and at 1.4, it is just stunning. The motor is very quiet and smooth, and the 50 1.4 focuses extremely quickly.

Z letter at the end of SAL50F14 does not only add extra $1000 to the price but also significantly improves image quality. Everything - colors, sharpness and bokeh look great. Super fast and accurate AF thanks to SSM, and finally this is the first dust and water proof Sony/Zeiss lens!

  Exceptional image clarity, beautiful bokeh, fast and quiet SSM motor, weather proof
