Lens structure: 8 groups of 10 (including 3 aspherical lens and 1 ED low dispersion glass lens) Lens angle of view: 75 ° -34 ° Maximum aperture: F3.5-5.6 Minimum aperture: F22-36 Aperture blades: 7 ( Circular aperture blades) Closest focusing: 0.3-0.45m Overall dimensions: 72.5mm x 83mm Lens weight: about 295g Filter size: 55mmFE 28-70mm F3.5-5.6 OSS is a compact and lightweight full-frame standard zoom lens. Its mirror body size is only 72.5mm × 83mm, weighing about 295g, widely used in scenery, snapshots, close-ups and other topics. As the overall length of the zoom process almost does not change, almost can be seen as “in zoom ” design, which also allows the entire recording system is more compact size. It is possible to make inappropriate judgments on the F E28-70mm F3.5-5.6 OSS if it is available. Although not with a small blue mark or G
