Ultimately, we can not recommend this. While it is seductive with its construction 100% metal and its super wide aperture of f / 0.95, it provides too limited image quality and is too "difficult" to use. The maximum aperture of f / 0.95 is a real plus to be able to shoot in very low light conditions and especially affect depth of field very marked. But is it really necessary on a wide angle? Not really in our view. This has a lot more sense on an equivalent 35, 50 or, of course, a 80 mm. We are perhaps too used to seeing goals exceptional and homogeneous dive, but the optical quality of this 10.5 mm disappointed us . In short, it is sharp in the center but only at the center. As soon as one moves away, the details become blurred. For crusty: net only subject in the center - it's a bit restrictive. Chromatic aberrations are also much too wide for a goal of this caliber. By cons, we appreciate the low vignetting and good control of distortions. Finally, the focus ring is much too long. It's almost unusable, even with the best digital assistants Manual Focus ( peaking and magnification). The lack of communication between the lens and the body is also very disabling. The object is however very nice and the build quality, faultless. Its all-metal construction is a real "plus" which contrasts with the modern objectives, usually plastic. We take pleasure to have it in hand. The new Voigtlander Nokton 10.5 mm f / 0.95 will therefore find its audience among those seeking a true wide-angle to their housing micro 4/3, who like to take their time and enjoy the soft images (very sweet). They will be happy to use this incredible maximum aperture of f / 0.95. For the others, we invite you to look at the 15 mm f / 1.7Leica Panasonic siglé or 17 mm f / 1 8 Olympus: admittedly a little longer, a little less bright, they are much lighter and compact, integrated auto focus and provide better image quality.

한마디로 혹평이군요.중앙부만 샤프하다고 합니다.색수차도 심한 편이고.다만 비네팅과 왜곡은 적다고 하네요.
