接環

有 Canon EOS 300D﹐想連接番一個舊時既 FD 300mm/F4 ﹐然後 piggy back 上望遠鏡影﹐有冇這樣的 FD- EOS 接環﹖

Please note the camera register, i.e. distance between the lens and lens flange of camera, of EOS is 44mm and that of FD is 42mm. This means when a FD lens is mounted to a EOS camera, it can never focus at infinity.

Because of this there is no mass produced FD to EOS adapter.

Thanks... and I search again, I saw this....

(I had to try the shops in TST like Chan Hung or Tin Cheung...... and not much chance...)


Canon have actually made two adapters for mounting Canon FD mount lenses on an EOS body. The first is a purely mechanical adapter (the "Lens Mount Converter FD-EOS"), and so lenses will not focus to infinity. They can, however, be used for macro work. The second adapter is designed for the following FD lenses and allows infinity focus:

FD 200mm 1.8 L
FD 200mm 2.8 RF
FD 300mm 2.8 L
FD 300mm 4
FD 300mm 4 L
FD 400mm 2.8 L
FD 400mm 4.5
FD 500mm 4.5 L
FD 600mm 4.5
FD 800mm 5.6 L
FD 50-300mm 4.5 L
FD 85-300mm 4.5
FD 150-600mm 5.6 L
It contains optics and acts as a 1.26x multiplier. The Canon part number is C54-2131 and the cost 10 years ago was around $240. It was available only through Canon Professional Services. I don't think it's still available new, but it does show up occasionally on auction and used gear sites. If you have a large investment in quality FD glass it might be worth looking for. In fact Canon offered it to ease the transition for professional FD users to the EOS system. I guess there aren't many professional FD users left now!

有塊玻璃，就算對到無限遠質素都唔會特別好。
