RX1 Night-time AF Test

Since there is so much talk about the RX1's AF performance, I shot a little video for you guys.

As you can see, it is very dark; probably too dark to be shooting without a tripod.

You can clearly see where the RX1 struggles, although it is unfair given the lighting.

Well anyway, a picture is worth a thousand words, so a video must be worth a million, enjoy!!

Re: RX1 Night-time AF Test

Man, that's so slow. Awful.

(kidding of course)

Low contrast scenes in the dark - difficult. Contrasty - quick enough.

While watching your video noted another up on Youtube -- he did a couple of focus tests using the RX1 but it has NO CARD flashing on the screen. One commenter said their RX100 focussed slower without a card (hard to imagine...but...).

Re: RX1 Night-time AF Test

nice! sorry for the hijack but whilst we are on the low-light topic, can you confirm if the flash can be tilted for bounce? i ve heard mixed messages and saw a non-production model with fixed flash..

Nope, the flash cannot be titled.

Saw the video, that's pretty much what the camera does.
When it struggles, it goes, comes back, goes again and you're finally focused.
Sometimes it takes 0.2 seconds, sometimes close to a full second.

The camera on the right laptop may be too close to focus (minimum focus distance is 30cm)

Re: RX1 Night-time AF Test

Most of the time, when it is failing to grab focus it is doing so on a subject I'd never try and shoot in the dark (e.g., zero contrast road or wall). When there is contrast to be found then it locks in more quickly than I expected after reading some early reports. I think it's looks just swell. Thanks for the video.

Re: RX1 Night-time AF Test

That is a somewhat spectacularly loud AF motor though, when the camera hunts for focus. My pre-order is still in, but I am still a bit concerned about the AF.

It'd be great if you could do a companion day-time test!

Re: RX1 Night-time AF Test

OK I could do that, what do you want me to shoot?  There's a small park near my office, maybe I can walk over during lunch.

Anything other than indoor bookshelves!

A quick video will probably silence most of the AF doubters out there. Your in the dark video certainly gave me a sense that AF isn't going to be an issue with the camera.

Re: RX1 Night-time AF Test

As a ff camera, that focusing in night is fantastic actually.

I don't think my 5D would be able to lock focus half of the time... The RX1 sounded like a weird product when announced but more I read about it, more I like it.

Re: RX1 Night-time AF Test

All this video does is show that the RX1 can focus in very dark situation. As it is a contrast-based focusing system, I find it normal that it hunts when shooting a flat white wall or a flat dark road.

Thanks for confirming that the RX1 AF is quite good in fact.

Cute. It's too dark to be AWAKE! It's a miracle any camera locked focus in this video.
