Hi,
Sorry, I am not familiar with cinema.
Can you explain the benefits of 70mm, for those of us who are shootings stills?
Best regards
Erik
70mm (just a pseudo-term like Super 35mm) is somewhat equivalent to 6x7 medium format. E.g., IMAX is 70.41 × 52.63 mm. Other than IMAX, "70mm" is also shot on 65mm film (Todd-AO 48.56 x 20.73 mm) - and projected back on 70mm.
There are movies being shot in IMAX and 65mm even today - The Dark Knight Rises, Samsara, The Master, etc. Not small movies. Obviously, there are cinematographers and filmmakers enamored with the "medium format look" and want to translate that into cinema. The lenses used are 'cinevised' versions of Hasselblad, Mamiya and Schneider lenses. What is stopping more productions are the cost and weight of film (and the camera, by consequence).
As you can see, the Todd-AO sensor size is not that big. It is pretty close to what medium format cameras have today. In fact, it is
damn close to what Sony has just released.
A thought experiment:What if Sony put down money to make a digital 70mm film (they produce movies) shot on their own medium format digital camera (they make cameras and computers) and then distributed that globally (they distribute movies globally) to cinemas (they are fighting a battle for digital projection), Blu-ray (they co-invented it) and the Internet (Luckily the only place they have no clue about) - to be seen on Sony 4K televisions? If the demand has been created by someone else, they will quickly push large sensor cameras into the market.
What makes me think they will? They introduced a 35mm full frame VG900 camcorder (but no Cinealta camera). They invented a completely new mount - E, and have also adapted it to heavy cinema cameras (called the FZ mount). The Sony A7R must have been in their sights when they did so. If they have agreed to a few MFDB sensor orders (that surely is in the lower four figures, optimistically), what is in their sights for tomorrow?
For years Leica have marketed the 'superiority' of their cameras. They did this by using the scarcity principle - low volumes at a large cost. What this does is create a huge market of people who lust after their cameras but can't afford them. Sony is the type of company that goes after such a market.
Suddenly Sony comes out with an A7R that rivals the best any of them (Leica, Canon, Nikon) have to offer. They started by selling some of them sensors. In the MFDB world, Phase One and Hasselblad have marketed the 'superiority' of the format (which is mainly the size of the sensor) for years. Sony has now started selling them sensors...
Sony never tries to
invent a market. They just wait for it to mature and then 'arrives'. They don't care about any particular segment, they want to dominate the entire market from end to end. Let's see the pattern here:
- Michael says a million visitors come every month to LuLa. Why would they come, if they are not interested in MFDB? Assuming only 25% of them are real humans, that's about 250,000 per month. That's not a small market.
- Steve Hendrix and Doug Peterson have consistently maintained that MFDB is selling quite well. Obviously, the combined marketing efforts of the industry as a whole are working. This is why Leica and Pentax showed interest.
- Why did Nikon feel the need for a 40 MP DSLR, if not for the demands of MFDB fans for cheaper '40 MP'?
- Every time there's a MFDB discussion, the topic turns to 'I wish it were cheaper'. What the MFDB manufacturers and their marketing have created is a huge market of people that lust for MFDB but can't afford it.
- Now Sony has shown interest. They are the masters of 'good enough products for cheap'.
The good news, one hopes, is, a 70mm cinema camera. That will definitely pique a lot of filmmakers' interests (in numbers greater than the total size of the MFDB market). These filmmakers won't demand still cameras of the same size, because the digital 70mm camera will shoot 8K (40 MP) frames at 24 fps. And just in time for the 2020 8K broadcast by NHK.
This will also put Sony ahead of Red and Arri, and back at the top of digital cinema pantheon. One camera to rule them all.
Just a hunch. Anybody see any benefits?
