Our review

Sony's trio of compact primes offer respectable optical performance, fast focus, and great handling and controls in a compact, lightweight form factor. The 40mm F2.5G is tack sharp wide open, with extreme edges sharpening up nicely at smaller apertures and nearly no lateral chromatic aberration. Unfortunately it suffers from textured bokeh and fringing due to longitudinal chromatic aberration. Focus breathing may be an issue for some videographers.

Good for: Portrait and low light photographers, drone videographers

Not so good for: Travel photographers requiring a versatile focal length range, videography requiring extensive focus pulls that may suffer from focus breathing
