Philip Bloom presents Letus EX3 1/2" Relay
9 months ago
DoP Philip Bloom introduces the long-awaited prototype EX3 1/2" Relay for the Letus line of DOF adapters in this video from CVP.com, the European distributor of Zacuto products.
In the video, Bloom demonstrates how to utilize a fixed focal length lens to control depth of field, while the exposure can be adjusted using the iris feature on the Letus 1/2” Relay lens. He also highlights the field of view difference between 35mm still cameras and 35mm movie cameras. The Letus 1/2”Relay adapter is designed to crop the image plane for the Academy format, which allows for the use of PL lenses without vignetting. Bloom says that the Letus EX3 1/2” Relay makes you feel as if you’re operating a 35mm camera. “It feels like a proper camera,” Bloom says, “and more importantly, it operates like a proper camera.”

Also, the EX3 is interframe design (Long Gap), so it you want to edit what you shoot, you would be better off with an intraframe type gear (Panasonic, SI, Red,, etc).
I do have Sony VTRs, but this new Panny blows the Sony out of the water based on specs only. It would be grand to see side-by-side projections of identical footage shot with both cameras, of course. Also, the Sony is 1/2-inch sensor vs. Panny's 1/3-inch, but in all honesty, these days one would really want a 2/3-inch sensor camera, anyhow.
RED is sort of like AVID these days -- here today, maybe gone tomorrow? I fancy the Silicon Imaging SI-2K over the Red mega-K monsters, anyhow, since neither Showtime nor HBO is insisting as of yet that I deliver to them @ 4K rez. ;~))

I am sure that a REAL comaprison of more side-by-side shots using the EX3 and the HPX300 will be coming soon, including exterior shots, right? :~))
The HPX300 looks and feels more of a D-film camera than the EX3 does, even though the EX3 for some reason is a CineAlta class camera. At that token, the HPX300 should be a VariCam class camcorder.
Also, let us not forget the fantastic Grass Valley Infinity 1000. That baby has a huge sensor and records to very inexpensive replaceable emdia, cheaper than hard drives. The Infinity also can record at 100Mb/sec and 4:2:2, it's just it does it by creating Motion JPEG 2000 images, not the proprietary AVC Intra codec that Panny uses.
Next to that, the cheapest recording/storage option is to go with a regular Sony XDCAM (not the EX series). It is just crazy that a Sony XDCAM media costs under $50, and the same capacity with the EX-series costs over $1,000. Of course, a camera recording to a spinning optical disc is also a little bit passee-looking... It's a tough choice out there, admittedly. But a wonderful marketplace nonetheless. I can't wait to see what I shall find at NAB next month!
