Birger Canon Mount-Aperture Reading/Setting

[Joe Taylor]

Hello

When using Canon EOS lenses mounted with the Birger Canon Mount, how do you read your setting? Example, I want my lens at f5.6, how do I know my aperture is set at f5.6?

I understand that your aperture is set with a toggle wheel, but after looking at the Birger web site, I am not getting the info I need.

Thank You

Until lens data gets sent to RED you have to count clicks. You have to know how many clicks 5.6 is from wide open or fully closed.

Not optimal.

When lens data is working you'll read the aperture on the LCD or EVF screen. If RED builds that in.

That sucks.

Am I correct in remembering that there is also no way to tell focus distance other than the tiny little window on the top of the EF lenses. At least until Red implements its /i lens data support. So, no measuring focus for quite a while.

The third way, is through the BlueTooth remote control.

Click counting may not be optimal, but it is one of the short term solutions that will allow the mount to be used - for some this means use for lens evaluation and preproduction, for others it means production use.

The best Option... this is what ill be doing..
Option 4 - hook up the lens to a canon camera.. adjust aperture, then hold down the aperture release button, and while holding, remove the lens.

That way you got your canon to suggest you an almost correct reading for your exposure and you get away with both shutter speed + aperture readings/set-up, plus you get a crop and a nice director's viewfinder that takes pictures for ya. And get to save some power from red and avoid using more cables.

Erik - Not that you don't already have your hands full - but has the remote been in development - is it likely we will see it in 6ms - a year? I know you don't want to play the time guessing game - that gets you in trouble here. But it would be helpful to have a general idea so we can plan.....

Yes... remote info please. One can only dance around this question for so long

As soon as we are shipping the Canon mounts and knobs in volume, we will open up a comment period and public developent of the remote. We will announce the schedule and scope of this in the coming weeks.

And for those who are about to ask for more status on the mounts, expect more information tomorrow.

Thanks for the response

Erik,

Not interested in Canon, but when are the Nikon mounts going to be finished?

More importantly -- how will they work?

Is there a schematic, drawing, list of features, description of how the thing is supposed to work?

What does the controller look like to follow focus?

Is it a rheostat that you turn back and forth to move the focus in and out?

How far from the camera can the focus puller be?

Does it have an easily markable disc around it to note focus points with a dry erase marker?

Is there some other kind of controller, in conjunction with a laptop?

How does "bluetooth" factor in to the operation?

Can aperture be changed in real time just like focus?

Etc, any other pertinent data.
