The calculation in the difference in relative apertures (count the luminosity) is simple: (5.6 * 5.6) / (0.95 * 0.95) = 35.įor mirrorless cameras with APS-C or Micro 4/3 sensor: In numerical terms, this means that 7Artisans 50mm 1: 0.95 should be 35 times lighterthan stock lens Sony 16-50mm f / 3.5-5.6 PZ OSS, which at a 50 mm focal length can use a maximum aperture of only 1: 5.6. Each stage gives a twofold increase in aperture ratio: 1 -> 1.4 -> 2 -> 2.8 -> 4 -> 5.6. 7Artisans claims that the 7Artisans 50mm 1: 0.95 optical design uses two low-dispersion elements from HOYA.Īmong the disadvantages are the standard optical problems inherent in such inexpensive high-aperture optics, first of all, strong chromatic aberration and very low resolution at the corners and edges of the frame at close focusing distances.Īperture F / 0.95 more than five steps wider aperture F / 5.6, which is used in some 'dark' stock lenses.

This series includes only three solutions: 25/0.95, 35/0.95 and 50 / 0.95 (from this review). This lens belongs to the 7Artisans line Firefly ('Firefly', this name is most likely a reference to the high aperture of the lens). In addition, sharpness at F / 0.95 is quite enough, for example, for some directions of tailoring. Separately, it should be noted that the 1: 0.95 aperture ratio is 'fair' and gives light transmission in the T / 1.0-T / 1.1 region (that is, the real aperture lens, expressed in T-stops, matches well the stated maximum aperture of F / 0.95). First of all, 7Artisans 50mm 1: 0.95 is aimed at creative shooting, well suited for some areas of portrait photography.ħArtisans 50mm 1: 0.95 is interesting for its very low price (this is the cheapest lens of this kind with F / 0.95), very high-quality assembly, a large number of aperture blades and a maximum aperture of 1: 0.95. These lenses are most often referred to as' fifty dollars'because of the 50 mm focal length.
