High Speed Telephoto Zoom Lens – you can quickly change it from a 150-450mm T2.8 to a 100-300mm T2.2

For shooting on film, this is the industry standard at the 450mm end of zoom range. It´s also the fastest 100-300mm available. How does this lens give you two sets of zoom ranges? – it comes with a separate optical reducer. When you insert that, all the focal length are reduced 0.7 times.

Choice of filters: Filters on the front of a long lens degrade its image of course. Our filter slot is near the back and it accepts one filter holder. The lens comes with two filter slots; each slot holds two 48 mm filters. One lets you use any two filters; the other comes with a geared rotatable polarizer and space for one other filter.

Centering and tracking: This is a big lens – 600mm long. Positioning of the elements and mechanical tracking must both be even more precise than in a shorter lens. Zooming moves are obviously very long but must stay centered. Sometimes we contact camera crews to get feedback on the equipment they just rented from us. A number of DPs have told us they´re surprised at how well a zoom lens this long stays on target all the way.

Heat and cold: Because it´s physically long, we have also paid extra attention to metal expansion and contraction. Instead of the usual aluminum, our lens rear section is thin stainless steel. As a result, back focus shift is invisible, even in arctic cold and tropical heat.
