Hi. Just trying to understand a little better. Is there any advantage to shooting in 1.2 crop mode over just cropping to that size in post processing? Thank you ...

For still images you get exactly the same result.

I think the 1.2x crop exists only because of video, but I'm not clear exactly why. I've never studied the video aspect of this camera much, since I almost never shoot video.

Yes, a smaller file. I use it with my wide angle 12-24mm DX lens at about 20mm because it gives me a 24mpx image that would normally be about 16 mpx in DX mode. Just wondering if there was any advantage to shooting FX lenses in 1.2 mode rather than crop down to that size. Thanks ...

No, when setting the crop in camera, the meter will consider only the cropped portion. That is true for any crop mode. In most cases it will not make a meaningful difference, but if you happen to have some bright light just outside the crop area but within the 35mm frame, the in camera crop will give a better exposure.

That said, I rarely use in camera crop since the flexibility of having the entire frame is more valuable to me than avoiding occasional exposure errors.

Yes, that is true, but for the 1.2x crop mode, there would have to be a very very bright light outside the tiny crop area, that didn't affect the metering inside the crop area. I guess I should have said the image would be 99% identical.

Same here. If I am shooting a smaller subject, I use center weighted metering and keep the whole frame in case I don't get the subject framed quite right. Airshows are a good example. I could easily fit the fast-moving aircraft into even the DX crop size, but very often it moves out of the center on me, and if I weren't using the whole frame, I might lose a valuable capture. Also, with airshows, I always use the camera on Manual Mode, so my exposures won't change from frame to frame, meaning metering is not an issue for cropping in that case.

I looked it up in the manual (not something I normally do until all else fails)!

On Page 67 of the D800 manual it says the 1.2X area is the FX Movie Movie format. So, that's the real reason for it.

I can't see any real value of the 1.2X crop for still photography.

Agree, it's usually not a concern. It's a bit more of a concern with DX crop and certain scenes where the subject is differently lit than the background.

Faster FPS: 5 instead of 4.

Great ... Faster FPS and higher than DX res image when used with certain DX lenses with no vignetting.

1.2 is the one that shows as 30x20 in top LCD - correct? And it's the one that is approximately 25mp?

And we get the 5fps without the grip?

I've been using this for birding.
