AF100 FCP Workflow for low-budget run and gun productions

I do totally hear about you moving from a 170 with a Letus or whatever to the AF100. That said,
mind that you're moving into a new format where you will likely get new glass. The MFT format
will change how much of your existing glass you'll look down. MM's are doubled .. F.stops are halved,
etc etc.

How does it change my glass? My nikons are the same focal lenght on my AF100 as when they were on my letus; the field of view may be slightly tighter, as the letus used an oversized frame as a DOF adaptor, it was not emulating the size of a standard motion picture 35mm film, it was closer to a FF 35mm size, like the 5D, which is vista vision. It is not a standard size for motion, but was used as it provided the greated DOF, which was the point of the letus. The AF100 i slightly smaller than s35, but is actually much closer than the 5D or the Letus to the FOV of actual S35film. Also, how are the f stops half as much on the af100. My 50mm is just as fast at 1.4 on my af100 as it is on my letus (the camera is faster, but that is another issue...). Again, sensor size my slightly impact the DOF, but a lens at 1.4 on a letus is the same 1.4 on the AF100 or any other camera. I really hate it when people keep spreading this, it is really breeding confusion, which gives people the wrong impression of the AF100.

On a side note, AF100 over a letus any day of the week IMHO. A nanoflash will makes the codec argument moot, and it is a cleaner image IMHO than any adaptor setup and is around the same price point.

The glass doesn't change at all. The amount you see through the glass changes, yes, but the glass itself is no different. And the f-stops definitely don't change.

It changes because of the cropping factor.

The term "crop factor" is at the heart of the confusion, and all the crop factors people are throwing around ar based of FF35mm frame size, which is used for still photography, and the ONLY video camera with a sensor that size is the 5D. The 7D actually has a sensor closer similar in size to a motion picture frame and it is refered to having a 1.6 crop factor, which is true about the FIELD OF VIEW compared to a FF 35mm STILL camera, but not a 35mm MOTION PICTURE CAMERA. The AF100 crop factor compared to a super 35mm frame, the standard of the film industry, is .18 if I remember correctly, which is almost negligable and easy to work around, especially with fast lenses and lenses such as the 11-16mm for the wide. That all said, the crop factor is in relation to the field of view of the senor in relation to another. The lenses focal lenght is the same REGLARDLESS OF FORMAT, as is the aperture. My 50mm is a 50mm regardless of what it is on, and the light is going through it just as fast regardless of the camera.

I talked to my lens guru .. he says Barry's right and I'm wrong :-) .. the F.stops don't change .. but the equivalent mm does. I think it's a little more
than 1.4 though (at least to my eye)..

I spoke to folk at Able cine in person and was told and presented with a wall chart. My 50mm lens will have a field of view of a 100mm. Yikes. I thought it was 1.2, not a 2.0. Anyway, don't care. I'll shoot and eventually see what I see, like what I see, buy what I can and shoot around what I can't. I don't even want to get into that conversation anymore. It's so confusing.
