all SLR cameras lens i want to understand?




XDXD


i want to know if all SLR brands can be used the same lens or different ones etc. like a Nikon lens on a canon camera or vice visa or other brands
thats A LOT of money you think anyone has made an extra extension to be place on lets say a canon camera and the extension is allowed to have any lens? because that would be very interesting product to buy



Answer
All camera manufacturers use a proprietary lens mount. Canon lenses for Canon, Nikon lenses for Nikon, Sony lenses for Sony, Penax lenses for Pentax, Olympus lenses for Olympus. The exceptions are Samsung and Fuji. Fuji DSLRs are built using a Nikon chassis and lens mount. Samsung DSLRs are built using a Pentax chassis and lens mount. Sony uses the Minolta Maxxum A-mount that dates back to 1985.

There are adapters that allow you to use a Nikon lens on a Canon or a Minolta SR (manual focus) mount lens on a Sony or Canon or Pentax or Olympus. The problem with adapters is that you have to use the lens in stop-down metering and manual focus. (Each camera requires a separate adapter).

The Tamron "Adaptall" adapters use the M42 screw mount on the lens and an adapter designed for each camera body. With it you could have a Pentax body and a Canon body and use the same lens on both cameras.

Minolta SR mount 250mm mirror lenses go for a premium on eBay and the word is they are being retrofitted with a Nikon mount. I've also seen a couple of SR mount lenses that have had the mount modified to mount to the Sony DSLR, supposedly with full metering.

All in all its still best to buy lenses designed for your camera.

Are camera lens fittings all the same?

i have an old minolta SLR camera with a few different lenses... i want to get a new digital SLR.... are the lens fittings standard, or would i need to buy another minolta?


Answer
All camera manufacturers use a proprietary lens mount. Therefore, a Canon lens will not mount on a Nikon or Olympus or Sony or Pentax body and their lenses will not mount on any other body. There are adapters that allow you to use a Sony lens on a Canon or Olympus but you lose a lot of the features like metering and auto focus. The one exception is the Fujifilm DSLR line which uses a Nikon lens mount.

When Minolta introduced the world's first full-featured Auto Focus 35mm SLR in 1985 they changed their lens mount from the MC/MD bayonet mount to the A-mount. After the Konica-Minolta merger, Sony bought the DSLR technology from K-M and is still using the A-mount.

If your lenses are from the SRT or X series of Minolta cameras (MC/MD bayonet mount) then you will need an adapter to use them on a Sony or Canon or Olympus DSLR. If you have an old Minolta Maxxum then they can be used on any Sony DSLR.
