APOQUALIA 1.7/28 large aperture f1.7/28mm lens weighs 60g and is 10.2mm thick, which is surprising compared to the current retrofocus lenses of 1/3 to 1/6 and 1/4 to 1/6 thick, and it can be said that it is lightweight and compact, but it demonstrates inconspicuous mobility in travel and city snaps, and the slight flare at f1.7 that leads to nice shots is suitable for indoor portraits. At f/2, the central flare disappears, and at f/2.8, the frame flare up to the middle part also disappears, and the good image can emphasize the subject. Resolution and contrast are sufficient at f4, and total perfection is achieved at f/5.6 to f/8. When you adjust to 2m at f8, the pan focus is from 1m to ∞, freeing you from focus and concentrating only on the photo opportunity.

Multi-coated all 8 surfaces provide beautiful "raw" coloring, 12-sheet circular aperture and astigmatism zero = S = M, and the front and rear blare are elegant and beautiful. One of the attractions is that it can be close to 36-40 cm. Suitable for close-up photos of flowers, pets, dishes, etc. The distortion aberration of 0.2% is 1/10 that of retrofocus lenses, which is equivalent to that of macro lenses, and this single lens is a versatile lens that meets a wide range of needs.
