Anybody looking for a very cheap and excellent focus / zoom handle should check this out. Cheapest in the uk for the varavon focus sling there is.

If was posted in the follow focus topic before VK pointed this out to me.

Looking at these other options, that latest one looks a bit on the expensive side but it's the only one that has a built-in solution for self-managing focus marks and that's a big plus.

Hi , please take a look at the panasonic lever (and band) : there are 3 parts where the fingers should apply the pressure. 1. the lever itself and 2 more. The guys at Panasonic's did indeed consider the matter, properly I have to add. then the other guys (at panasonic's marketing) invented a price LOL for this thing. But it works...

let me post a pic ... it will be easier for me . gimme a minute

the DMW-ZL1 is fine , actually better than the lever on the sony HDR-FX1 that I also use. The proper way to handle the zoom with that lever is to hold the gear from below moving with 3 fingers. Grabbing the lever from the top or the side with two fingers is not the correct way to handle ANY lever. I have to report that zooming with a 14-140 and the ZL1 gives a much better fluid movement than the sony FX1 (that also gives a big progressive rocket pretty good for slow zooming, but that's a motor. Still with the Sony I zoom manually covering for example a soccer game (for sudden changes due to the nature of the game). So I can confim that the GH2 with the 14-140 and the ZL1 (again grabbing the lens from below) gives better results compared to the sony FX1. problem is that's ridiculously expensive, but all the other levers that I saw (on ebay for example) aren't much cheaper and ALL tend to handle the lever from the side (and that will never give a fluid zoom, regardless of the size of the lever)

I use the zoom levers as shown in the top post on nearly every shoot when using the 14-140 and 7-14 for smoother zooms. Also use one on my Canon 50mm 1.4 for focus. Love them, though interested in getting a few more - will consider some of these other options.
