Actually, the 12-60 could be a half-decent lens for video. It’s got mechanically coupled focus so you could rehearse and use camera tape to mark it off much more effectively than with a focus-by-wire lens, although the puller would have to go without levers. And if you ensure that you stop down to an aperture that’s no larger than the maximum for your most zoomed in section, you could do a shot with zoom as well.

Not ideal compared to a dedicated cine-lens, but assuming you’ve already got the 12-60 it could definitely be used for the kind of carefully planned shots in most fiction film-making.

An interesting thing about this lens and the compact primes is that they have exchangeable mounts. They come with a set of adapters and shims for Arri PL, Canon EF and Nikon.

I would assume Zeiss is considering adding a m4/3 mount instead of coming out with a new product. I don’t see what they should, as the lens can already be adapted to m4/3 as it is.

“I guess for us “poor” IndieFilmmaker’s the Olympus Zuiko 12-60mm f/2.8-4.0 is a far more affordable choice. It covers a much more interesting focal lenght, it has autofocus and it’s damn cheap”

Autofocus isn’t something you want for cine. If you leave the AF on, you will ruin every take as the lens tries to decide where you want to focus. If you leave it off, you won’t be able to consistently track focus manually (there’s no accurate focus scale).

Likewise, extreme focal lengths don’t work very well for moving images, especially if you move the camera.

As far as “cheap” is concerned, cine lenses are typically rented. It’s an expense, but so is food, transportation, etc. There’s no need to buy a cine lens unless you are going to use it every day. Most low budget shows spend a few weeks shooting (at most), and months planning, writing, editing, promoting, etc.

I suppose this is a Parfocal lens
