FS7: New Sigma Cine Lenses

I guess that's one use for parfocal ability. For me, parfocal ability is most used to punch in quickly with the zoom lever, find focus, and zoom back out, knowing your wide shot is focused. I still don't find the electronic focus punch as quick to use and the digitally zoomed image as well presented.

Been a long while since I could do that and feel comfortable about the results. Damn you, a few years of stills lenses...
 
I had exact same experience - a few weeks ago myself. That's my first shoot in probably three years with a focus puller (wireless one)- so I welcome the throw of the Sigma's as well.
 
Checked out a few of the new lenses during a Sigma Cine event at Hot Rod Cameras.

Overall they're pretty nice, & lighter than expected, but found the zoom rings to have far too much throw, especially for a 2:1 lens, making it a bit tricky to change focal lengths from one extreme to the other.

Unlike the 50-100mm, breathing wasn't bad on the 18-35, which isn't new information, but what surprised me is how much the 50mm prime breathed also.

Haven't handled Tamron's Cine primes, but heard breathing is almost non-existent.

How heavy was the breathing on the 50mm? Objectionable? Or just noticeable?

Were you able to check out any of the other primes?
 
Mark,

I went to Hot Rod Cameras primarily to pickup a GH5, & see their new space. Illya gave me a tour of the facilities, & I spent a bunch of time talking to other DPs, but squeaked in a few minutes to play with each of the lenses.

The Sigma Cine event had one of the typical scenarios that manufacturers set up so with a handful of various cameras pointed at a couple of actresses interacting with each other. They were sitting at a table 10' feet or so away from the cameras, & there wasn't really anything closer to point the lenses at, which made it a bit tricky to judge how a typical pull might look, so I just racked back & forth while looking at the edges of the frame.

The 50mm was the only prime mounted on the cameras, & I didn't get a chance to check out others. Breathing was quite noticeable, but in fairness I was just cranking the follow focus, & don't how far I was pulling, or how objectionable it look in normal use

The Sigmas have got the throw of a cine lens where you'd use a follow focus or AC to precisely alter focus and would almost never ever go front min focus to infinity in a shot.

Stuff like the fuji lenses have a shorter throw for more one-man-band use.
 
Actually the Sigma Cine focusing rings rotate 180*, while the Fujinon 18-55 supposedly rotates 200*.

What throws me off is the Sigma Cine zooms have a 160* zoom rotation, which is excessive for it's 2:1 focal range, whereas lenses like the Cabrio 19-90mm have a 120* zoom rotation & are 5:1.
 
Bern - your post #31 - did you mean the Tokina cine primes? Or did Tamron also re-house some still lenses into cine?

Very kind but don't do yourself a disservice :)

The Red has arrived. It is sexy as hell. Will probably hang onto it
