[Murat Pak] "Well, can I get nive DOF without buying any adaptors ?"
Not really. Do COW searches on "DOF" and "Depth of field"... you will find a lot of threads, and some ways to "trick" the eye into thinking you have a shallower DoF than you really do.
Without an adapter, about the best you can do is use lenses as long as possible (zoom in), and make sure the iris is wide open (use ND filters if needed to help with overexposure).
The EX series does have a 1/2" chip, which helps a
little compared to a 1/3" chip, but not much. If you compare it to the film world, even the 2/3" chip in a full-sized camera is still only about the same frame size as a 16mm film frame... so the DoF is still much much deeper than a 35mm frame which is about five times bigger.
[Murat Pak] "If not, can I use a letus extreme without buying a 35 mm lens ?"
No, you need 35mm lenses with any of the adapters, from the lower-end Brevis35 and Letus35, up to the mid-range RedrockMicro, or the Rolls Royce P+S Technik Mini35.
[Murat Pak] "what are the prices of these lenses"
They vary wildly like anything else... from a few hundred bucks for Nikon SLR lenses, up to well over $100,000 for a new set of Cookes. A lot of DoF converter users use still-camera SLR lenses because they are so cheap. It can be done, but they are
much more difficult to use than real cine primes, and the results are sometimes marginal (although sometimes good). Because so many people have begun using DoF adapters the lens market has really dried up. Just a few years ago you could get a decent set of cine primes (although probably not superspeeds) for $10K, maybe even less. Unfortunately now prices have at least doubled and even tripled in some cases.
You can always rent lenses. Many DoF adapter users will use SLR still lenses for day-to-day projects, and rent a real set of PL mount cine lenses for mission critical projects.
BTW, if you are not in a hurry for more info, there is a fairly lengthy article about DoF adapters coming out shortly in the next issue of Creative COW magazine (written by yours truly).
