For those who don't want to click on the link here's the conclusion...
"The Sony 24mm F1.4 GM is a new masterpiece from Sony and well deserve its GM label. It is certainly one of the best 24mm if we consider all criteria together
Excellent sharpness wide open across the full field, even wide open (Note : for close distance corners are “only” very good at F1.4/F2)
- Fast and accurate AF with very good Eye AF performance
- Small and light
- Excellent bokeh and very smooth background blur
- Fast Aperture : F1.4 : perfect for low light
- Very small focusing distance + F1.4 = perfect for small depth of field
- Very good contrast and 3D effect at F1.4 for people portraits
- No field curvature
- Very low distorsion
- Very low coma (suited for Astrophotography)
- Suited for video thanks to click less aperture ring
- Very good color rendition (but Zeiss Loxia 25mm F2.4 is excellent)
- Very well built, weather sealed.
There are however a few area where it is not “perfect”
- Very small amount of CA
- Resistance to flare is good but not excellent
- Vignetting at F1.4 & F2 (a future Lightroom Lens profile will correct it)
- Price (but in line with GM price range)
The lens is very versatile and will be the perfect choice for landscape, street photography, low light, architecture, people reportage, full body portraits, astrophotography, and this both in photo and in video."
