Auto CMOS Alignment ?

[RED-Tank]

Hi All, I don't know whether this is valid to RED ONE or any 35mm camera. I was reading a news about the new coming Canon Mark III photo-camera and it has a feature of "auto-focus-alignment-system" that can automatically adjust the CMOS to up to 19 different len used, so that you can always get the perfect focus shoot. Most of the DSLR won't have such feature and you will have to send camera back to manufactor to re-align the position of sensor to make perfect focus for only one of your favour len.

I wonder RED ONE has such feature ? or I am just talking nonsense ?

answer or brick are both welcome :p

The new feature of the Mark III is an electronic calibration adjustment of the AF system and not the CMOS sensor.

It's just a slider in the menusystem where you can adust the lenses to focus further back or foreward to match it to the camera body.
You could say that iw was just an obvious missing feature from older Canon cameras with autofocus, as it's a known problem that Camera and lens tolorences sometimes causes the AF system to focus behind or in fromt of the focus point.
Without this menu option you'd have to send the camera to a factory calibration of the lens programming and AF system.

As the Red camera doesnt have a AF system, it wouldn't apply at all.

Thank you very much Anders for answering my question. :D

I didn't online for the last two days, there must be more stuff I have to learn through.

Please do you know what other features available in normal prosumer camera but won't be available in high end camera like RED-ONE ?

I am coming from the background of using Sony PD150, 170, FX1, Canon XH-A1. I keen to get a RED-ONE basic (which the most I can afford) because RED-ONE has everything I have dreamed of for long time: good price, changeable len (vary DoF), re-use 35mm photo-camera lens, high contrast & dynamic range, 120fps and extreme high resolution for future proof project.

But I need to catch up my skill in handling high-end camera like this, I believe my knowledge of prosumer camera may not be useful, so please can anyone enlight me more ?

Now I know that RED-ONE has no auto-focus, very likely it doesn't have zoom control (has to be manual) ? how about peaking, zebra, backlighting, white-balance, focus-assistant, exposure lock (things quite common in prosumer cameras)...

many thanks again for your help.

Red is fully manual. That means manual zoom, manual focus, and manual exposure. It does have exposure histogram display (no prosumer video camera has that, that I know of) and I believe zebras also. It has some kind of focus-assist, the details of which have not been revealed. I have not heard that it does auto-white tracking. The RED design intent was based on 35mm film motion picture cameras which are manual, for the most part, rather than a TV news crew camera or a prosumer video camera. I believe the design assumes that you will be doing some level of post-production, at least as far as basic things like white balance.

Consumer and prosumer video cameras are designed to function when used by someone with no knowledge, experience, or interest in camera operating techniques. Red was not designed that way.

Thank you very much jbeale, is it possible to gain that kind of knowledge without working in film industry ? I mean do you have any good text book recommended ?

thanks again.

Hi,

PL film mounted lenses are accurately collimated so that the focus with the lens at infinity falls at 52mm.

It is important that the PL mount be set with an accuracy of 5 microns.

Still lenses are not set that accurately.
