You would have thought Canon would have given these lenses STM, to make them properly video-friendly.

1st Thanks to the poster for putting up the video. It is great to start seeing the 1Dx in peoples hands.
2nd The poster has said future videos will be horizontal. He is new to posting videos online.
3rd This video reminded me of another video put together by a Canadian Comedy troupe. It is pretty funny and not meant to hurt anyone's feelings. :-)

The f / stop system used by photographers is unfortunately pretty useless, being only a simple ratio of the front element to the focal length, it was largely replaced in the film industry by T (transimission) stops, which instead measures the amount of light a lens is able to pass through. So a lens with an f/2.8 rating might not allow as much light through as a lens with an f/5.6 rating, but without measurement it's impossible to tell. Dxo have done some measurements, but as yet they have not measured this lens, so there are no actual T/stop figures for it , my personal feeling is however that this lens will not have a high value due to its 'different' optics.

You and I (and many other photographers on both sides) have very different ideas of what "reliable" means. And this is perfectly fine - that's why both types of modes exist.
The settings that the camera guesses on can change wildly, depending on where exactly you're metering. Your shots will not always be consistent. If you're using evaluative metering, changes in things like the background can have dramatic effect on your exposures. If you're using spot metering, changing where you're metering even slightly can also dramatically effect what the camera thinks is "right".
I guess my main point is that the camera does not have an intuitive sense of what I'm photographing. It can only guess, and allowing it to guess gives it the opportunity to guess wrong. Will I guess wrong too? Absolutely, but it trains me to keep an eye on the histogram and adjust. Exposure will never be something that you should "fire and forget" unless you're taking snapshots. (Again, this is my thinking, not what everyone should think.)
Your bulb mode comment is amusing, but entirely misses the point. The camera is good at precisely exposing the sensor for a specific time with a specific aperture. Nobody disputes this. What is disputed is whether the camera can automatically expose every frame properly. Some people think it can, and they use Av/Tv. Some people don't trust it completely, and they use Manual. Nothing wrong with either.

I am doing an outdoor shooting this morning. I will be in manual, 1/300, iso50, f/2 - f/4
Just use the sun as 1 of the light sources, not the only source.
Overpowering the sun means less light/contrast/blownout whites in the bg
yeah but you only have pretend sun over there anyway so its not hard to overpower
Lol
Show off!
In Italy it's the same, but considering it's a really light-duty tripod, how can you demonstrate that the product was defective and that you didn't overload it? Warranty of course doesn't cover damages derived from improper use.
...it seems like letting the camera set the exposure and then using EC when necessary is faster.

Are you saying you wouldn't expect a lower-line tripod from a major brand to last more than a couple of weeks?
Yes, if the major brands clearly states that it supports up to 1Kg/2.2lbs and you load a lot more weight on it.
Because we keep on paying it.
My last 3 bodies have been grey, my last expensive canon lens was grey, anything else I've bought off brand or used.
Canon are taking the mickey.
The 40mm may well have been worth £229 to me, but it rankles a bit that it's worth only £129 to an american.
As much as I hoped for such a lens, I won't be buying it. Unless I get it grey.
If the retailers won't stick up for you (jacobs on sticky wicket, jessops indebited to tune of £10m to Canon) then stick up for yourself.
What did you expect when you bought a plastic-ish tripod? It's only made for lightweight gear. So tell us, what were you using on it? i have a 055xprob and the quality is excellent. A friend of mine has a really old manfrotto, and it still works perfectly.
If you want a good tripod, it comes with a price. What did you expect out of a plastic-ish tripod?
