This also changes everything!!!

I think the crop factor will be more like 2.3-2.5x which is a real issue. my 16-35 will suddenly be 37mm on the wide end, no good really. also, the lack of DOF will be a big issue too.
Shame, I was really excited about this camera as I read the webpage but was confused why there was no mention of sensor size until i got the the specs page, now I know why 🙁

It’s kinda neat… but you think Blackmagic would have learned a lesson or two from all the people screaming about their Canon DSLRs and what those won’t do…
I think there are a few things keeping it from being a “real” camera… mostly the small sensor, the limited lens mounts (no PL mount, Blackmagic?), and poor audio inputs (you’d think they’d have XLR inputs with phantom power, to be a real player).
Also (unless I missed it in my first glance), the only way to hook up a “real” monitor on location is to have one that takes SDI inputs, which many don’t. That seems pretty basic.
The throw-away price tag is certainly a draw, though. It does look like something that many production companies (including my own) might strongly consider as a “B” camera, but probably not as a primary.

HI. The camera I shot this with is a hand built prototype. They haven’t finished working on the sensor calibration yet, that takes care os noise, and dead pixels. This is very early days for this camera.
This is also why the ISO and Noise is still very much up for grabs.

[Steve Connor] “I think he’s talking about the magnification factor, the lens will still work it just won’t be that wide.”
[Chris Kenny] “It’s going to be hard to get very wide on this camera.”
Yep, I believe I pointed this out. FOV will be more narrow… but I think this is different from saying that there will be fewer choices of wide angle lenses for this camera.
[Martyn Greswolde] “I think the crop factor will be more like 2.3-2.5x which is a real issue.”
Compared to a full frame stills sensor, yes. Compared to a Cinema 35 sized movie sensor, probably more like 1.20:1.
[Martyn Greswolde] “my 16-35 will suddenly be 37mm on the wide end”
No, the focal length doesn’t change at all, the characteristics of the lens will remain the same. Smaller sensors don’t magnify the picture, they resolve (or crop) a smaller portion of the image.
[Martyn Greswolde] “also, the lack of DOF will be a big issue too”
To match the DOF of a larger sensor at a given distance, you adjust the apeture. In this case, it should be 1/4 stop up (or so).
Did anyone feel that Black Swan lacked for wide shots or shallow DOF? If not, using a sensor that’s larger than Super 16 shouldn’t be an issue.
FWIW, this issue has been discussed at length on dvxuser.net. Below are links to two threads that may be of interest.

To obtain the same DOF on a 1.3 APS-H sensor as you get from a full frame sensor you need to shoot a full stop wider. This is correct for still’s so I cant imagine they would be any different for video.

Agreed. On first impression, this looks like a great VFX camera. Would love to do some chromakey tests using CinemaDNG.

They must decide the price first and set out to build a camera second. Nope XLR put us over $2999.00, nope have to keep that small sensor because they are cheaper than full sized sensors…
The FIRST thing I look at on a new camera is the sensor size and I’ll tell you why. In most rooms of a home in a car or even on the street you can’t get the framing you want because you have to be so far away from the subject. Plus shallow focus etc…this is the look of and features of a full sized sensors and I won’t go backwards.
I’m not crazy about an on-screen menu, prefer buttons…sunlight can make it difficult if not impossible but it’s not a deal killer, the sensor is, no matter how cheap it is.

Yes, comparing APS-H to Full Frame stills. Comparing Academy 35 (22×16) to Micro Four Thirds (17.8×10) it’s about a 1/4 stop. The BM sensor, being roughly the same size as the AF100 @16×9 should be pretty close DOF wise. At least, that’s what makes sense to me. Truthfully, that’s one of the things I prefer about the AF100, DOF seems much easier to control vs. the 5D. Of course, that’s on’y my opinion.

Hi John, thanks for posting, despite some of the FUD being posted around other forums many of us can see what a useful camera this is going to be.

After looking at the second link you posted I worked out thats what you were comparing it too. Problem is, with one of the selling points being you can use EF lenses, they are saying we want HDDSLR shooters to buy our product. With the +2x crop and the 2+ stops drop in DOF they are ruling themselves out of this market.
I would have thought allowing EF-S lenses or 4/3 would have been a better way to go.
