Broadcast style lens

[Jiri Bakala]

It might have been answered somewhere but these treads are so hard to search... anyway, here is the question:

For my (nature) documentary work I am interested in using the type of a lens such as broadcast Fuji or Canons. Fairly wide with a double extender. The type of work I do often means a one man operation, in the field, no time to change lenses or manpower to carry lots of extras. Also, the ability to use zoom cradle control and tripod zoom/start/stop controls would be nice too, and sometimes almost necessary (zooming, focusing and paning at the same time - without an AC)

So, what would be the lenses that would have this functionality while also having the quality to work in 5k? I guess a good B4 HD Fuji or Canon wouldn't quite be good enough and the focal length and field of view would change drastically. What's Red's recommendation?

Thanks.

Oh, I meant to say, this would be used with Epic S.

B4 lenses would only cover Epic-S in 2k cropped format, roughly 2/3" /16mm sized image. With 2x extender in, they might cover 3k, but probably not 4k. If lightweight field work like this is your predominant use and you want fast wide range compact servo zooms with high magnification, Scarlet 2/3" might be a better choice.

The practical options for Epic-S would more likely be a range of still lenses. Steve Gibby could give you better input on that.

I believe you need an additonal optical device to use a B4 lens on a non three tube (chip) camera as the lens is designed to work with a optical prisim between it and the film plane.

I expect Red's B4 mount will have the optical correction built in. Their B4 to PL adapter for the R1 does.

Sony is rumored to be coming out with a couple of S35 servo zooms for the new F3, but no one knows what the mount will be or if it would work on an Epic.

Ah, but either way I guess we are degrading a 5K camera (Epic S) to 2K recording, aren't we? That would be a shame and it wouldn't work for me. I want to be able to shoot large format (Imax-like) nature films and the lure IS the ability to shoot in 5K but with also keeping the flexibility of mobility and ease of operation. When are the SONY lenses supposed to be announced? NAB?
