Friday, August 17, 2007Canon t-rings
Had a customer, yesterday, that ordered the wrong t-ring for his Canon Rebel camera and there have been others. Maybe a little history would help.
Back in the 90s, when camera makers were switching to autofocus lenses, some manufacturers used the same lens mount for their new autofocus lenses as they had been using for their manual focus lenses. Examples here include Nikon and Pentax. Some manufacturers, though, did not. Examples here include Minolta and Canon. A Canon manual lens is defined as a lens with no autofocus capability. Manual focus Canon lenses and cameras haven't been sold for years. If you want an all manual focus Canon lens or camera, you need to shop used. T-rings for this lens mount will be advertised variously as Canon FD or Canon T or, more often, just Canon. An example, here is the Meade 07370 and the Celestron 93413 A Canon autofocus lens is defined as a Canon lens with autofocus capability. The fact that Canon autofocus lenses can also be focused manually is irrelevant. Canon autofocus lenses and cameras all fall under the umbrella of the Canon EOS system. If you own any Rebel (digital or film), Elan or any D series Canon camera, it is autofocus and it takes an EOS t-ring. A t-ring for an autofocus Canon, whether it be a Rebel, an Elan or a D30 will always be labeled as an EOS. Examples here include the Celestron 93419 and the Vixen 3776 Hope this helps. Comments: |
