I'm wondering, would it be possibile to use s16 cinema prime lenses with this camera? I suppose that it will have some vignetting due to the sensor bigger than s16 format. That's would be a shame.
Another question: if I use m/43 lenses, what would be the crop factor? I'm thinking about the zeiss cp2 with m/43 mount, but I don't know exactly what crop factor I should consider...
Looks like about 1.5x to me with BMCC's current sensor.
That'll get ya wide!
crop: 36mm (canon full frame) / 15.6mm ( BMCC active size) = 2.31 crop
11 mm ~~> 25
14 mm ~~> 32
15 mm ~~> 35
16 mm ~~> 37
17 mm ~~> 39
24 mm ~~> 55
35 mm ~~> 81
50 mm ~~> 115
55 mm ~~> 127
70 mm ~~> 161
75 mm ~~> 173
85 mm ~~> 196
100 mm ~~> 231
135 mm ~~> 312
180 mm ~~> 415
200 mm ~~> 462
270 mm ~~> 623
300 mm ~~> 693
Thanks for the list.
Seems I have everything except the 11mm covered. Never really shot that wide anyway.
You've never shot wider than 25mm? That seems to be as wide as you can get on BMCC (with an EF lens). Lot of distortion with an 11mm lens just to get to 25mm, no?
The stuff I do generally does not need to be shot wider that 24mm.
11mm on a BMCC crop sensor uses mostly the middle of the lens. Sharper there and less distorted.
There are many great films shot on 16mm film that have no issues with distortion.
There are very few cinema films shot on full frame 35mm. Most are shot on 35mm cine (Super35). Most common focal lengths being 35mm, 50mm & 85mm. Super35 has a crop factor of about 1.5. So that gives you 52mm, 75mm & 127mm on a full frame camera.
It's only really since the launch of the 5D that people have become obsessed with the full frame 35mm look.
I shoot with a S35 sensor and I have trouble getting ultra wide, particularly without distortion. I've never shot with M4/3, 16mm, S16, or anything smaller, so I appreciate your optimism, as I plan on owning this soon!
I shoot with a AF101 (so m/43 sensor) and nikkor lenses. The wider I own is a 17-35 f/2.8, which become a 34-70 on the af101. Not very wide, but I must admit that only twice I needed something wider. I'm planning to buy a 11-16 tokina but I'm not desperate.
Tokina 11-16mm, that's what I was thinking, thanks!
M4/3: How close are you able to get to a human subject without noticeable geometric distortion with a wide angle lens? Let's say at 17mm...
Well the 17-35 is a wide angle lens with a lot of distortion by default, especially used on a full frame HDSRL (i like it a lot in photography though, personal taste), With m/43 I noticed sometimes distortions on the edges of the image, if the camera is too close to geometric elements. I never noticed problems with human subject, but in general I always use the 28-70 or the 85 wich has less problems in that way.
I was very close to buying the FS100 before this camera came out, and am now very unsure which camera to buy. The FS100 has a beautiful super 35mm sensor but it doesn't have a lot of the stuff the Blackmagic does. Provided you could afford both, which would you go for?
It sports in-camera high FPS modes that are simply not available from any other (relatively) affordable cameras today. So it will produce some great slo-mo, as illustrated by sample videos.
FS100 seems overpriced for what it does, and has no built-in ND filters.
I don't think so it takes PL Mounts cause , it is not mentioned neither BMD website nor in its specification, to rectify this issue third party adaptors are available.
Have you tried it with PL ?
Nope, didn't had the chance yet.
Just spoken to CVP - I am number 7 in the list of pre-orders. They think anybody abve 30 would need to wait until the end of the year befor they get "lucky".
I don't need the BMD Cinema Camera anymore and am looking for people intrested to buy my slot. I am based in London for any face to face handover or can post the camera anywhere.
Could anyone give me some advice on buying the BMD Cinema or the 5D mk III? I currently own a 7D and use it for school purposes, like shortfilms, photography and so on. Now as I have managed to earn enough from media related jobs, I've decided to invest in a higher end camera. But the problem is; should I keep the 7D as a still camera and get the BMD, or sell the 7D and combine the 5D III as a still and film cam? And yes I loove the 35mm look ... but then the BMD has 2,5K and RAW.
hopefully Mr. Bloom would get this hands on the BMD for some tests in the next month or so.
