One-touch zoom function

The 70-210 mm lens can be simultaneously focused and zoomed with one control simply by sliding the Zoom Focus Ring along the length of the lens barrel while, at the same time, rotating the ring to bring the subject into sharp focus. For extra ease in focusing, focus with the Zoom, Focus ring adjusted to the maximum telephoto focal length (210mm) and then zoom to the desired position. Once sharply focused as above, the lens remains in focus at every focal length.

Macro function

This lens focuses from infinity continuously to a minimum focusing distance of 1.5m (4,8ft).

  • The engraved magnification on the barrel is based on the longest focal length scale (210mm) Also shooting are available at an other focal length. however the magnification will be less

Infrared photography 

When using black and white infrared film, compensation is necessary because of an unseen focus shift in the infrared spectrum. To compensate for this shift, focus normally and check the subject to camera distance shown by the white index line. Then rotate the zoom/focus ring until it is aligned with the infrared distance line marked “R”. Compensation is not required when using color infrared film.
