Mix camera/lens platforms or reinvigorate vintage glass; Fotodiox has hundreds of ways to mount lenses onto your DSLR or SLR camera. Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality. Versatile, Dependable, Adaptable Putting old lenses onto new, high-performance DSLR or mirrorless cameras seems counter-intuitive so why would anyone want to? The simple answer is that many older lenses can capture images that have that elusive quality known as character. For photographers or videographers who want to create unique images that express their personal style, character can be even more important than resolution numbers, corner-to-corner sharpness, and other advantages of the near perfect lenses that are quite common today. The imperfections and aberrations of older lenses are the very strengths that set them apart from modern lenses. Additionally, a fully mechanical lens is likely repairable longer and less expensively than modern focus-by-wire lenses. Old lenses also let you change camera systems, or your mount can get retired and your lenses won’t be bricked. At the extreme case, some mirrorless lenses require firmware updates for every new body, so even if the mount stays around lenses won't stay on that update list forever (for instance Nikon's new E lenses are incompatible with cameras just two generations old).

Please check the support articles on the Fotodiox Knowledge Base for possible solutions on a variety of camera brands.• 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, and since manual lens mount adapters do not power the lens, those lenses will not be able to focus.• Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.• If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop. • To remove the adapter, move the release lever (circled in red) in the direction of the red arrow: All pictures are for illustration purposes only.

Print Modified on: Mon, Feb 17, 2020 at 9:16 AM 'Crop factor' is incorrect and misleading terminology, '35mm equivalent focal length' is more accurate as what you are really asking is; what is the new angle of view of my lens when on this camera? In photography, the 35mm equivalent focal length is a measure that indicates the angle of view of a particular combination of a camera lens and film or sensor size. The term is useful because most photographers experienced with interchangeable lenses are most familiar with the 35mm film format so this gives a common ground for everything to refer to. All crop factors are based on 35mm full frame as a standard 1:1 reference point. On any 35mm film camera, a 28mm lens is a wide-angle lens, and a 200mm lens is a long-focus lens. However, now that digital cameras have mostly replaced 35mm cameras, there is no uniform relation between the focal length of a lens and the angle of view, since the size of the camera sensor also determines angle of view, and sensor size is not as standardized as film size was. The 35mm equivalent focal length of a particular lens–sensor combination is the focal length that one would need for a 35mm film camera to obtain the same angle of view. 35mm 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 1.5x for Nikon APS-C ("DX") format, 1.6x for Canon APS-C format, 2x for Micro Four Thirds format, crop factors of 5x to 6x for compact digital cameras and even higher crop factors for built-in cameras of mobile devices like cell phones or tablets. Everything is based on 35mm being the 'Standard' 1:1 reference point:Lens SizeFilm/Sensor SizeDivide By4x535mm FF3.46x735mm FF2.16x635mm FF1.66x4.535mm FF1.3 Using a 80mm Hasselblad (6x6) lens as an example: 80 ÷ 1.6 = 50mm. So an 80mm Hassy lens is going to give a similar angle of view to a 50mm lens when used on a 35mm full frame camera. Moving down in size from 35mm needs additional math.
