Absolutely. Perrone totally knows his stuff, and I rather enjoy seeing how we can look at the same thing from totally opposite sides of the spectrum, and still be completely serious and yet totally understand where the other side is coming from. I think I used to drive him crazier, but I think he's grown to understand me better now.For those unaware, Barry and I have a great deal of mutual respect for each other.
Well, there's only so far down on the ground they could start. The GH1/m43 sensor was their starting point. I don't know for sure that it will be the actual GH1 sensor (I know Jan's been quoted as saying that, but as far as I know that's not an actual press release). Could be that chip, might be a re-engineered "video" version of it, might be some advanced "GH2" sensor, we don't really know and we'll find out in a little under five months.So Barry, honest question. Why did Panasonic go with micro 4/3 when they could have gone for something more standard like S35? Especially since they were starting ground up as you say?
But the point is, their factory has the capability to make m43 chips and there are m43 lenses. And the Broadcast side is way smaller than the consumer side, so while Broadcast could never sell enough to get the benefits of mass economies of scale, the consumer side certainly could. So by making it compatible with m4/3, they leverage off the millions and millions of m43 cameras out there, and inherit a range of lenses, while making it adaptable to any camera lens.
Frankly, the biggest obstacle towards us getting the "dream" camera -- a professional video camera with all the advantages of the SLR -- has been the lenses. Up until a year ago, there were NO lenses that were appropriate for a video camera with a large sensor. The major lens manufacturers (Fujinon, Canon, and Angenieux) stopped their video lenses at 2/3". Angenieux makes film lenses, but ENG-style or video-appropriate autofocusing lenses -- there aren't any, at ANY affordable price, for larger chips. So when Panasonic Consumer decided to invest the R&D to create the GH1's kit lens, I think that's the turning point. The GH1's lens, if you've used it, is really quite remarkable. 14-140, with excellent CAC, completely silent video-style autofocus, OIS built in, and it has communication with the camera body's electronics to overcome pincushion and barrel distortion so you get a rectilinear 14mm wide. Only real knock against it is that it's slow, at max f/4. Other than that, it's pretty darn good, quite video-appropriate, and most importantly, it's the right price.
But when you're looking at making a $6,000 camera, what lens do you put on it? A Nikon? Some of us might find that okay, sure, but pro video guys are gonna cringe at using a breathing tiny-focus-range stills lens. And DSLR zoom lenses are horrible. What are you gonna do, use a one-ring push-pull zoom for video?!?! What do you do for the video guys?
The GH1's kit lens (and a couple of their others, I think the 20mm pancake) do the job that they needed done, at the price point they needed it to hit. That lens sells for like $850 MSRP. It's the right weight, the right size, the right focal length, and the right features, to make the PACKAGE make sense.
If they went with S35... what lens do you put on it? An S35 lens? Where are you going to get that? I had a Cooke 20-100 on my Red One, it was about six hundred pounds and three feet long (okay, slight exaggeration, but only SLIGHT).
That's why I think there's little chance of Canon coming out with a large-chip video camera. There's no video-appropriate lenses for APS-C. None. There's no mass market consumer base to draw from (yet). Maybe they'll make one (they are Canon, after all) but so far... they haven't.
So yes, while folks could (and many will) use SLR lenses with an AF100 (including me, I have a fairly complete Zeiss ZF set waiting for an AF100 to go on), that's not appropriate for the (relatively) mass market of professional video shooters. For the video professionals, wedding shooters, event shooters, ENG guys, anybody else who wanted to use this camera, there had to be a video-appropriate lens. And they said they're making it for "digital cinema and professional video", so it had to serve both purposes.
The GH1's 14-140 is as video-like as you're gonna get; only thing it's missing is a power zoom, but other than that, it acts and feels and focuses and stabilizes like a video camera lens.
And that lens covers m4/3.
So, added all together, taken in context as a complete package, the logical decision is: the camera will be m4/3.
Would it be nice to get that extra 3mm for 35mm? Sure. But again, the question is: what lens would you use with it? How does the total package make sense?
I wasn't in on the planning meetings, so this is me with my (limited) knowledge of the manufacturing business, and my knowledge of the general consumer/prosumer consumer landscape, reconstructing their thought processes, but it all makes sense so I don't think I'm too far off.
