Clairmont ISCO 140-420mm T2.7 Lens
This beast is a custom made lens from Clairmont manufactured by ISCO Germany before they were bought by Schneider around the same time they were making optics for NASA. It was made to compete with the Panavision SLZ3 and Hawk 150-450 and in the little booklet of literature it claims to be a TRUE T2.7 all the way through and claims the SLZ3 or Hawk wasn't. In reality the lens ramps just a touch at the long end. It covers full frame all modes on the Venice and cuts the corners just a touch on Alexa LF OG. 4.5K 2:39 and UHD 16:9 looks great on the LF. Can take 58mm internal filters to get extra ND otherwise 6x6 clip on matteboxes can be used.
It is a very nice performing lens with neutral tones and a beautiful look. There is zero focus breathing and it is 100% parfocal. Zero distortion through the range, unlike the Angenieux 12x. It holds light on bright edges amazingly and is an extremely high performing lens. Close focus is about 10'6". There's no lens (prime or zoom) in this range that performs better than this lens. It is a very large lens weighing about 43 lbs and about 55lbs with the included custom Ronford Baker unified support plate that supports the lens and camera on the same platform for the best possible support. The lens has fully geared iris, focus, zoom. It doesn't have a focus collar but has rod mounts on the plate for motors. Focus throw is about 340º. Zoom and focus is surprisingly light so you won't need crazy strong motors or anything. There is a fluid zoom drive built onto the lens for added protection against gravitational zoom drift and shipping.
It is in great shape with minimal cosmetic flaws, only light coating marks etc from use. Focuses and zooms very smooth especially considering how much glass you're moving. Was serviced by Keslow until sold off. It's properly collimated and hits its marks through the range. Image is phenomenal it performs incredibly. Way less distortion than Angenieux 12:1, in fact it has virtually no distortion. Nice colors with medium contrast and nice flares if you hit it directly. Otherwise it controls flares nicely. No light bleed on hard edges, almost no chromatic aberration, doesn't breathe at all. An incredibly well performing lens and extremely rare -- I believe there are maybe 4 in existence. Extremely high quality German engineered optics available for sale for the first time ever.
It comes with a custom lens support made by Ronford Baker that supports the camera and lens on a unifying plate, caps, and a custom case for the lens. Lens is about 43lbs and needs a 2575 or 120ex to balance properly. Perfect for stage performances and night shoots.
