Much has been said about Sigma’s new cinema lenses – both good and bad. Particularly their high speed zooms, the 18-35 T2 and 50-100 T2. Sigma recently loaned me a pair of the zooms and so I took the opportunity to get to the bottom of things.
Prime lenses are smaller, lighter, cheaper, faster and optically superior to zooms. So why bother using a zoom? There are some instances where a zoom might just be the better choice.
Often, cinema zooms cost more than the camera they’re mounted to. This year however, there’s been a sudden wave of budget cinema zooms introduced, aimed at the owner/operator market and priced accordingly.
Since 2008, filmmakers have been in the market for full frame cine primes. Lenses that cover the larger format yet still offer all the mechanical advantages of a proper cinema lens.
How do the Contax lenses fair compared to it’s contemporaries? Let’s look at the Contax line compared to other Zeiss lenses both new and old: the Super Speeds, Classic (ZE/ZF.2) and CP.2s.
