IRIS steps
I hope there are going to be more steps for iris control then the XL1s. Not sure about the XL2, but I find the stepping when opening and closing the iris quite annoying.
|
I can tell you it stops down to f/9.5 before closing completely. Whether more discrete steps have been added in between, I'm not sure.
|
I noticed that the wheel is back on the H1 instead of the lever on the XL-2. That's good.
|
One of the things we asked Canon to do was provide a smooth iris
tranistion. Obvious image changes caused by stepping are a 'prosumer' alert and hard to edit around. |
Well, if it's anything like the XL-1/s, then it still has steps however subtle. Why can't it just be a free moving wheel, the way it should be?
|
That was requested along with HD-SDI. At least they got that right,
but I hope the wheel is like the ring on a pro rig. |
Sorry but it is not an analog ring. It's a wheel with a discrete number of contacts.

Hey Chris,
So it's the same as the XL1 and you see the iris changes with each click? |
Yes that's right Jacques. If there's any improvement here, I'm thinking that it would be the same number of steps as before, but since the f/stop range is not as broad as before that means each step is more discrete (that is, smoother) than before.
26 steps from f/1.6 to f/9.5 is smoother than 26 steps from f/1.6 to f/16. |
0.2 stops per step as opposed to quarter stop steps (assuming they are uniformly spaced).
|
In the Sony world the PD-150/VX-2000 had only 12 discrete clicks which resulted in very noticeable manual changes. With the PD-170 they doubled this to 24. I don't know how this works on the Z1, but the wheel turns smoothly with no discernable clicks and the transitions look completely smooth - huge improvement. Let's hope Canon did something similar.
