I'm not sure when everyone started relating all focal lengths to full frame 35mm, it's maddening!! Not that hard of a concept to grasp.

Luckily it seems this is more the case on boards like this and
among still photographers. I've worked as an AC on a few shoots
and never once did the DP ask me to 'put on the lens that is equivalent to a
50mm on a FF camera.' They'd ask for a 35mm or 85mm or 135mm. No
trying to calculate 'equivalent focal lengths.' Everyone knew what
each lens looked like on Super 35 and that was the standard.

It couldn't be simplier. And how does it not make sense?

It makes visual sense. Here's the math: http://www.josephjamesphotography.com/equivalence/

Here's a real-world test verifying the math: http://brightland.com/w/the-full-frame-look-is-a-myth-heres-how-to-prove-it-for-yourself/

An 18mm lens on a Cx00 1.5 crop sensor looks like a 18*1.5 = 27mm on full frame (5D etc.). 18-80mm = 27-120mm on a 5D; the math is helpful for still photographers who also shoot video.

Sorry but that makes no sense- it makes it more confusing if nothing else... and I'm a lens guy- I can only imagine what it does to others....;-)

It does make sense. Here is 2 images from the Panavision link I posted before. It basically shows the same thing but it's probably less confusing.

lol, honestly I never even bothered looking into it.
I only own one camera and shoot everything on it, my life seems simpler.
 
Before my previous little post is definitely buried under all your (interesting) FOV stuff, I ask you again :
What's the maximum weight supported by C100 EF-mount, without lens bracket ?
Thanks.

All right, I'm in too.
But.. 1,2 Kg and no lens bracket.
What about the maximum weight supported by EF-mount ?
1 Kg like E-mount or more ?

I routinely use the Canon EF 70-200 f2.8 L IS II lens plus EF 2xIII TC which weighs (1.49 kg + .325kg) = 1.815 kgs. This I do without any lens bracket/support. At times I have mounted the 70-200 lens on the tripod and the C300 hanging behind it. The weight of C300 with monitor and microphone should be around 2.4 or 2.5kgs and gone upto 3kgs. Using the C300 since 2012 and no issues with the EF mount.
 
Thanks Indiawilds !
I was somewhat confused after have seen some NAB videos.
The 18-80 was presented with lens support for C300 MKII (there is a thread below the fixed rocker element) and without for C100 MKII.
 
Does anyone know if the power zoom would work when put on another EF mount camera? And worse, on a metabones adapter ?
Just asking if this could be a good match to,say, a FS5...

All I was able to get out of the Canon was that they should work but will not provide power to run the Servo so you'll need an AB or IDX solution with a power tap....

The Canon Compact-Servo lens in theory should be powered off any EF Mount including Metabones adapters when mounted to the Sony FS5.

We'll find out more as we get closer to the Compact-Servo lens release date.

would love to see a test with the 18-80mm using the new MC-11 on a Sony FE camera like the A7sII or A7rII. what are the odd of it focusing? probably not good but if it did that would be a very interesting matchup! can we expect the servo zoom to work properly from the MC-11 / Sony FE camera?

I do wish lens makers allowed over-stopping, as in opening up or closing down beyond the spec of the lens. I am sure they have to worry about markets and public opinion, but i wish overclocking culture applied to lenses sometimes. Not because i want to shoot sharp wide open, but because sometime i want to shoot with an effect, and going soft is ok. And sometimes i need more or less light over image quality and that is ok.

overall, f4 is fine. Especially with how sensitive and large the sensors are these days. Worth trading the size of a lens for a stop or two.
