I'm not following this at all. If supply is flat  (not linear and certainly not linear with a slope of 10), then Cost(Q) = 10 (not 10Q)   So in the first example P = 100-Q, the curves cross where 10=100-Q, so Q = 90 and P = 10. Second example they cross at, P=200-Q = 10 = Cost(Q), so   Q=190 and P = 10 (more sales, same price)

In this case, the supply curve and MARGINAL cost are the same. Cost(Q)=10Q implies MC=10.

So in the first case, you would maximize Total Revenue-Total Cost= P*Q-C(Q)=(100-Q)Q-10Q.

Taking derivative with respect to Q, we get 100-2Q-10=0, resulting in Q=45. Plugging Q=45 back into the demand we get P=55.

I taught intermediate microtheory for 3 years at UNC-Chapel Hill, so for the sake of my former students, I hope I haven't f**ked this up.

Thanks for all the advice! That Arri-Manual was great. I Plan on shooting with a c300. I have a 5D2, but I wanted to avoid using it as a B-Cam.

I plan on using QPCARDs for some general consistency throughout.

Elflord, you're thinking of perfect competition. At worst this is oligopoly. Equilibrium is where Marginal Cost=Marginal revenue: Draw down to the x-axis to get Q, up to the demand curve to get P.

If you don't believe me, here is a simple analytical example:

Assume supply is flat (just like you said): Cost(Q)=10Q

Assume original linear demand: P=100-Q

New linear demand (after adding video): P=200-Q

Equilibrium price in the first case is 45

Equilibrium price in the second case is 105

That's monopoly, but it will be true in all cases where firms have pricing power(AKA: not perfect competition)

Seriously, do some reading on supply and demand curves if you don't understand why removing video will not lower price.

You first. Removing video will shift the demand curve down. Equilibrium price will be lower. That being said, the video on the 5D3 isn't that great, so I'm not sure how big of a shift you'd actually get.

And why not offer 7D II and 5D 3 as "basic version" for stills capture only (but with liveview) at an attractively low price - similar to what that type of DSLRs cost, before video was grafted onto them?

Um, honestly I don't think this would affect the price of the 5D3 much. The video is basically a free tack on. It's clear that Canon felt that they could not justify putting NO video (since the 5D2 had it), but it's totally nerfed below its capabilities(it's processor is capable of at least X2 the bitrate). The real video/stills hybrid will be about $5000, and probably called the 5D-C.

<p>Another suggestion is the 1D C isn’t going to be the only Cinema EOS DSLR by the end of 2013.</p>

5D-C. It's got to come, if for no other reason than to justify the nerfing of the video on the 5D3.

You can't start off a film, especially a short film, with 7 minutes of f***ing housekeeping.

I'm going to be using this for short films, and studio photography.

I was looking at this. I was hoping for something similar, but a bit lower in price.  But I want it to last.

Hey axil, do you ever use remote panning tripods? If so, do have any favs?

I'm looking to upgrade my lighting for video for shooting with my 5D. I currently use 3-500watt tungsten lights. Anyone with any bright(apologies for the pun) ideas?

Looking to spend between $1000-2000(US)

Video is not the reason this thing is more expensive. The 5D2 HAD video when it came out and it did not cost this much. Getting rid of video will not change the fact that Canon is getting greedy.

The reason the price has increased is because DEMAND has increased, thanks in large part to the success of the 5d2.

268
Profit maximization occurs when marginal cost equals marginal revenue. Video features don't increase the marginal cost much, most of the added cost is in the fixed cost of firmware development.   

I could see it shifting up the marginal revenue curve because video modes are desireable(for some). Thus the general appeal of the camera means a higher equilibrium price.

This same thread over on EOSHD somehow turned into a S___-talking match between the blog owner and Phil Bloom.  It's worth the price of admission.

I would stick with 30fps at 1080p because it allows you to crop in post(if you want). It'll be plenty smooth. It'll be hard to make it look film-like in post at 60fps, because it necessitates a faster shutter speed, even if you were to drop frames.

F11, seems reasonable.  With a shutter speed of 1/50 or 1/60.  I'd use the sunny or cloudy white balance setting depending on what you get. They work pretty well outside. Pay close attention to your screen, because it's very easy to blow out the highlights shooting metallic things in the sun. You, should zoom in on bright spots to make sure they aren't being clipped.  Although, if you are in bright sunshine, some clipping will be inevitable if you want any detail in the shadows.
