p.1 #1 · p.1 #1 · 1Dx - Extreme low light focus capabilities


Hi,

maybe it's too early, given the rather small amount of 1Dx bodies around, but I'd love to ask a question to the wedding photographers in this forum who had the chance to shoot with that camera.
I have recently shot a very challenging wedding whose dinner / reception was in a nice italian villa open-barn, lit only by few candles. Available light required me to shot at ISO800 with my 1Ds mkII and Auto-ISO up to 3200 on the 5D mkII, 35mm F1.4 1/40s, 85mm f1.2 1/90s. To get faster focus lock i used a flashlight assist beam on the 85, while the 35 mounted on the 5d always hunted a bit; it ended up with 60-70% usable shots from a focus perspective (exposure can be worked on in PP, motion blur is not a matter of camera/lens).

My question to you is, how does the 1Dx perform in very / extreme low light environments? Is the intelligent face recognition usable with poor lighting? The question is open also to the 5d mk III owners.

Thanks and forgive my english as it's not my primary language

I think everyone has a different definition of "extreme low light?" No camera is going to focus in pitch black.

That being said, your camera settings ("ISO800 with my 1Ds mkII and Auto-ISO up to 3200 on the 5D mkII, 35mm F1.4 1/40s, 85mm f1.2 1/90s") suggest to me that it wasn't that dark. I shot 3200 on my MK II all day long. I think with my MK III, I can shoot 6400 all day long.

I have no problems focusing in low light.

This statement intrigues me: "(exposure can be worked on in PP, motion blur is not a matter of camera/lens)".

missing link?

here's a (bad) pic of the location. You can see there are very few properly lit spots (where of course people didn't like to play around :/ )

For AF in low light, skip the 1Dx and just go to the 5D3; much better AF than the 5D2 and still way cheaper than the 1Dx.

My 1D X did EXTREMELY well at a wedding last weekend that was very dimly lit, as in, candles in a few jam jars around the dance floor. I was amazed at how well it did.

Given the setting you listed... I don't think it was very dark. ISO 800.

No, but f/1.4 @ ISO 25,600 is Oh and the exposure for this picture was pushed up 1.7 stops in Lightroom.

It was actually worse than that as I had to push it in post 1.7 stops as I said. The auto ISO maxes out at 25,600 so that was it.

There, and this is no joke, were a couple tiny accent candles in jam jars hanging above the dance floor, and that was it. It was too dark, they did everything themselves as far as setup but they were expecting the candles to light things up more, and they didn't. They should have had some flood lights pointing up at the roof they strung up, or something. You could barely see their faces.

Umm, why such a fast shutter, and are you allergic to flash??

Impressive, yes.... but why?

^ I can't speak for Will, but I'd rather use ambient light than flash in almost any situation. The point at which I switch to flash varies with light, but on most receptions if I can AF at 6400 while holding 1/125 at f/2, I'll go with ambient. And regarding the shutter speed he used, that's right around where I need to be to have a decent chance of stopping motion on the dancefloor.







Here's a shot from our most recently blogged wedding. 10,000, f/2, 1/50. I almost never deliver anything with motion blur, but I liked the subject, lighting, and composition enough here to keep this one. However, if I'd taken this at 25,000, that would have given me another stop of shutter speed to work with. But I have trouble generating keepers at that ISO with the D700; 12,800 is about my limit on most weddings.

I didn't shoot like this the whole dance. And 1/125th is fast?
