Canon FD 400mm F2.8L

이번에 카메라 샵에서 들이게 될 FD 400미리 L 렌즈입니다.
조리개를 조여 쓰게 되겠지만 F4정도의 전면 마스킹에서 어떤 성능을 보여 줄지 자못 기대가 됩니다..
넓은 평탄면을 보유한다는 장점만으로 가치는 충분하다 생각합니다.

The world's fastest 400mm lens. One of the many prime factors why professional photographers have considered Canon to be the ultimate sports SLR camera system. This lens features the widest aperture of any 400mm focal length lens made then.

The use of 2 elements of UD glass to minimize secondary spectrum. Rear-group focusing eliminates any change in the overall length of the barrel during focus, and the employment of Vari-pitch cam focusing system slows down focusing motion at longer distances.

Occasions or events that may prevent a photographer from getting too close are some examples where the use of a super telephoto lens is necessary. Such situations may even prohibits the use of flash as well. High speed long telephoto lenses like the New FD 400mm f/2.8L , are indeed an advantage for those assignments.

Features such as the one-touch revolving mechanism and a provision to facilitate prefocusing on an area where the subject may appear, combined with the lens' overall dimension and relative high speed (naturally at the expense of its weight as well - which tipped the scale at 5.3 kg!) make it a strong considerations for sports, news or nature photography. As far as this focal length is concerned, Canon has not been challenged by any other manufacturer in terms of lens speed until late 1989 when Nikon finally launched its manual focus Nikkor 400mm f/2.8 IF-ED, which to me, was a bit silly since they already have a couple of AF cameras by then, including the much-hyped Nikon F4 pro model.
