2. List of Nikon F-mount lenses with integrated autofocus motor

   en.wikipedia.org/wiki/List_of_Nikon_F-mount...

   Nikon DX/Sigma DC/Tamron Di II/Tokina DX: Denotes a lens that is designed for APS-C DSLR sensors. Use of this lens on a full-frame (FX) sensor will likely cause vignetting. All full-frame Nikon DSLRs are able to detect DX lenses and crop the image accordingly by default. However, the viewfinder view is likely to be constricted.

   All Nikon full-frame "FX" DSLRs have a DX-compatible mode that, by default when a DX-format lens is attached, crops the captured frames to the DX format and adjusts the viewfinder to reflect the smaller capture area. This can be overridden by the user if desired. There are basically three types of F mount Nikon lens: MF = Manual focus lenses

4. Crop factor - Wikipedia

   en.wikipedia.org/wiki/Crop_factor

   For example, a 28 mm lens delivers a moderately wide-angle FOV on a 35 mm format full-frame camera, but on a camera with a 1.6 crop factor, an image made with the same lens will have the same field of view that a full-frame camera would make with a ~45 mm lens (28 × 1.6 = 44.8). This narrowing of the FOV is a disadvantage to photographers when ...

   en.wikipedia.org/wiki/Cataract_surgery

   Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [1] The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.

6. 35 mm equivalent focal length - Wikipedia

   en.wikipedia.org/wiki/35_mm_equivalent_focal_length

   35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...

7. History of cataract surgery - Wikipedia

   en.wikipedia.org/wiki/History_of_cataract_surgery

   Cataract surgery is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [3] Over time, metabolic changes of the crystalline lens fibres lead to the development of a cataract, causing impairment or loss of vision.
