Answers to some questions
on Mar 17, 2010 at 4:23:44 pm
Andrew Laparra: Thanks for the kind remarks, Andrew. Glad the article helped you out!
Ed Fabry: Unfortunately 00:08-00:09 is not the EX1 shot, but thanks for asking! I actually have a lot of parts that I modularize together, depending on what kind of shoot I'm doing. I have a "beast" handheld rig (weighs a ton), a medium sized rig and a more compact rig that doesn't use a lot of parts. I personally prefer a 7" LCD screen when shooting; it doesn't mean my head has to be on the camera and I feel I can adapt to my surrounds a little better/safer, but that's just me. I know a ton of people love the loupe eyepiece concept.
Alister Chapman: I definitely wouldn't discount the aliasing (or the rolling shutter) issues. There are ways around it, but the point being is that they can be there and should be handled accordingly. And yes, the resolution is in fact full 1920x1080. Dynamic range is a topic that can go back and forth though between the EX1 and 5D2 however. The EX1 has about 10 stops and the 5D2 has about 8.5 stops. However, as an owner of both, I can achieve latitude on my 5D2 that my EX1 just can't handle, especially in low-light situations. The 5D2 also has a pretty good highlight priority mode if you're shooting overly white shots to help bring in latitude for those whites. Don't forget too that although the image is ultimately reduced to 1080 HD, it is in fact coming from an incredibly high sensitive 14-bit, 35mm full-frame sensor compared to the EX1's 10-bit 1/2" sensors. As far as latitude goes, I'd generally give the blue ribbon to my 5D2 over my EX1. But again, I feel this is a moot topic as they're both exceptional in dynamic range, depending on shooting variables.
Alvin Remmers: Thanks for the kudos, Alvin. The article says I designed that mount, but I did not (note to editorial staff =). I bought that mount from FilmTools.com. It's called the Gripper 490 with 3/8 ballmount and 6" suction cup.
Suchet: You've hit the nail on the head. The possibilities are really endless with this technology. Sure there are some drawbacks, but the versatility is amazing and the quality is great for what it is and how much they cost.
Jim Kelty: These DSLR cameras have progressive sensors. There is no interlacing at all with these cameras. The easiest way to prove this is shooting something that moves quickly in the frame. Pausing said clip, interlacing would have horizontal fields to make up the moving object, but with the DSLR footage, the moving object is clean of that. No interlacing at all. If an app shows the clip as being interlace in the information, then the applied metadata for the clip (really just a boolean flag) itself is incorrect or corrupted. Definitely progressive!
James Houk: I too own an EX1 with a Letus adapter and a slew of Nikon F and Canon FD lenses that I can mount to it. In fact, I used that setup (and still own it) prior to owning the 5D2. I completely agree with your comments on the virtues of the EX1 over the 5D2, except for one, with regard to dynamic range, as noted above to my comments to Alister (not so much a disagreement, but rather a moot topic). And with the Letus, I introduce less edge-to-edge sharpness and stop-loss, as small as it is. If aliasing and/or rolling shutter isn't a factor in the shot, then the 5D2 produces a much better image for me than the EX1 does, Letus or not. And FWIW, XLR inputs are a moot point for me personally, since I'm using the Juiced Link device to gain said XLR inputs. Obviously not as ideal as my EX1's XLR inputs, but a solution nonetheless. To add to your other comment, the audio codec in the 5D2 is uncompressed (up from 44.1kHz to industry standard 48kHz with the new 2.0.3 firmware update). You wrote, "And the shallow focus of the 5D can be accomplished on the EX as well, with a DOF adapter. In many cases this combination is actually superior to the 5D." Unfortunately I have to highly disagree with this. My EX1 + Letus + Lens combo weighs a TON. A real pain in the neck actually. Couple that with stop-loss, edge-to-edge softness, battery swapping for the (noisy) Letus motor and the 5D2 is the clear winner for lens interchangeability, mobility, clarity and quality. I agree though that the EX1 can be a better ENG/EFP camera in most situations. I make that clear whenever any asks.
Mads Nybo Jørgensen: Yeah, comparing the codec qualities between the 5D2 and EX1 is a little tough only because, well, when it comes down to it, both are quite compressed (35Mb/s for the EX1 and somewhere around 38Mb/s for the 5D2) and both are 4:2:0. Purely from a codec standpoint though, I'd say the EX1 might have the edge in some areas, but it's kind of a moot point. What exact cost comparisons did you want to get info on?
Alister Chapman: Yup, I agree with what you're saying in your second comment.
Steve Martin: As noted in my above reply to Jim, it has to be some kind of metadata error, me thinks. The footage is definitely 100% progressive. Either the boolean flag is corrupted in the file's metadata or it's just incorrect. I'm siding with the latter!
