7Artisans 10mm f/2.8 Fisheye review by SonyAlphaBlog

SonyAlphaBlog reviewed the 7Artisans 10mm f/2.8 Fisheye lens and concluded:

The 7 Artisans 10mm F2.8 Fisheye (300 euros) is a Compact stereographic fisheye with good sharpness in the center as of F4 and good on the entire field as of F8. Color rendering is good and background blur is soft.
The closest competitor is the TTArtisan 11mm F2.8 Fisheye (300 euros) that offer a similar rendering with a better sharpness but a less good resistance to flare. On 24Mpix the 7Artisans will be recommended, on 42/50, 61Mpix the TTartisan will be more suited
