I am not saying that this will be true for others.. but this sensor does not limit me in DOF.

This image gives me all the shallow DOF I will ever need or want.

This was shot on the plastic 50mm f1.8 canon wide open. Not a great lens for filmmaking, but there are similar lenses that are more acceptable. My point is that this camera is more than capable of giving me a shallow DOF that so many crave. :)

Love that!!! What did you do to it to get the flesh tones so nice?

Very little...

Slid the white balance to "3164" clarity to "+9" and the Vibrance to "+39" in light room

Pic is not working for me...
if its a screen shot from your Mac, its the PNG.
open it in Photoshop (any image app) and save as JPEG.
Weirdness with PNG and this forum :)

I think it was a side effect of taking screenshots with my retina display. I shrank it down a bit :)

I actually like that lens quite a bit. Cute baby, BTW.

How many different color temps were in there? Looks like three and a possible. Haha.


50's pretty telephoto on this camera, shouldn't have any issue separating objects as long as you can back up.

Nice to see the performance of the nifty fifty, which I have used for all kinds of photo and video work, not telling the clients it's price though. Actually sometimes I do tell, just to brag a little after they make a comment about how nice THE CAMERA makes pictures (and not me).

DOF, I totally agree. People who have issues with not getting small enough DOF just don't know enough about optics I think. Just get close and make sure there is enough space between the subject and the background. Anyway, when you look at motion pictures, the DOF is often not that small. especially for wide scenes.

I don't think BMCC DoF is in question any longer - what I've been seeing in comments still are people that don't think you can get wide-angle with this camera.....

Yeah, there was a lot of evening light coming into the room from a big glass wall, as well as street light and tungston from the room :)

Honestly I like the DOF on this camera that 2.8 gives me (se pic attached), and you can get wide all day long at the fstop.

Expected to download a clip of some really nice lighting and framing with super shallow DOF. And...there's a high key drooling baby :P

mbeck are there two separate light temperatures here? Or are they near a window? I'm getting two white balances. Oh and thanks for posting!

It would be great to get more lenses at F2.8. Reality is that the majority of users here won't have glass that is 1.8 on all their lenses, and even if they did, most would rarely shoot wide open.

Had a play around with the first one mbeck, nice job mate!

Yeah, big glass wall with evening light, and street lights mixed with the tungsten lighting inside.

To me this seems like a good lens choice for the portrait. I was assuming I'd use a 35mm lens for portraits (and it would be nice to see a comparison of the 50mm and a 35mm), but this demonstrates the 50mm looks good in terms of composition of a close-up with other actors in frame. I prefer not to get too close physically for a close-up shot and the 50mm may be perfect for that perspective I want (i.e. minimal facial distortion without faces looking flattened).

By the way, I wanted to thank you for sharing your experiences with the BMCC. It's been great that a frequent poster on the forum got his hands on the elusive BMCC. I hope you can find some time to keep up the good work that we appreciate so.

What are you going to do, shoot on all your projects in closeups on one telephoto prime lens from far away?

no problem, I just wish my schedule allowed for more!

No, I am going to shoot at 2.8 on my 11-16mm and on my 17-50mm. but most of the shallow DOF you see out there is fairly telephoto. I just think that those times where I want that look, I can get it.

BTW, I got my adaptor for my 1.4 50mm NIKKOR today. I'll post some shots tonight :)

I am uploading some video now.. but here is a quick grab from the 1.4 NIKKOR 50mm.

Also, here is a DNG from the same Lens (stopped down, but I can't remember to what)

Here is a low light DNG from the 1.4.. lots of FPN. This camera is a low light camera, just not a no light camera :)

Man, that 1.4 gives you some pretty shallow DOF! Were you like 10 feet away from the piano? ;-)

@rick.lang - Whoa, nice job with that low light example... I wasn't able to pull much of anything out of it. I'll have to give it another shot.

For comparison purposes, here's what the BMC m43 with the Voigtlander lenses will deliver:

With 25mm f/0.95, it will be equivalent in field of view and DOF to a 5D Mark II at 50mm and f/2.4, or to a Super35 camera at 35mm and f/1.4
With 17.5mm f/0.95, it will be equiv in FOV and DOF to a 5D Mark II at 35mm and f/2.4, or to a Super35 camera at 23mm and f/1.4.

Not that you'd always want to shoot wide-open, but that's as wide-open and as shallow as you're likely to get.

Thanks Barry. The question in my mind was never whether or not the the BMC could produce shallow depth of field, or if it could go wide, but how the depth of field compares to other cameras at wider focal lengths.

Barry Green
09-14-2012, 02:51 PM
Well, to get equivalent depth of field at equivalent field of view, you need to open up a BMC about 2.5 stops vs. a "full frame" camera...

What would it be versus a "super 35mm (e.g., Sony F3)?

Speaking of DOF and sensor size. Sony Australia put up a demo video of the A99 with some terrible use of DOF. The A99 seems nice and the FF/135 gives some impressively shallow DOF but it's overuse is pretty obnoxious.
