Rx100 as timelapse camera

Offline
#1 xoda
I'm thinking of getting an RX100v basically exclusively for timelapses. I currently use my Nikon D90 to shoot timelapses, but it's a bit large and heavy especially since my primary camera is already a full frame DSLR. How well would the RX100v work for this purpose? I know it has a timelapse app

I don't know that camera specifically. But I'd not rely on any built in time lapse feature or time lapse app in a camera. Mostly you won't be able to do more advanced stuff like holy grail shooting with it. Form my workshops I know that nearly all non DSLR cameras cause more or less problems when shooting time lapse like we would like to do.
I'd at least make sure, that you can connect an external intervalometer. That would be my basic requirement so that I don't have to use any integrated time lapse feature.

I just shot a test timelapse with this new camera.

About 30 mins real time. Aperture constant f/1.8. ISO constant 125.

The shutter speed changes from 0.6, 0.8 1.3, 1.6, 2, 2.5 sec


However, it's not letting me do a Holy Grail workflow. Why is that?

ThatÄs because the camera is in A mode (changing shutter time automatically). There is no need to do any holy grail and LRTimelapse will not allow to do so because there are no decent steps in luminosity. Check out the blue curve - it's quite smooth. It makes no sense to do the holy grail approach in this case that's why it's deactivated.

Yes - one of the benefits of the Sony timelapse app built into the camera is that it can allowing for "AE tracking" which slowly adjusts the shutter to the changing exposure.

However, it's still a jump. It goes from 1sec -> 1.3 sec -> 1.6 sec -> 2sec. Basically 1/3 of a stop per jump. And there's still a small difference in luminosity when they make the jump.


Isn't this basically what qDslrDashboard does anyways? That is, slowly ramping up the shutter speed for a sunset timelapse? And in that case, do you need to do a holygrail workflow?

Normally, when you shoot Holy Grail you do much bigger steps (1/3 stops minimum) that's what the HG Wizard compensates for.
In your case you have much smoother adjustments (other cameras do this too in A Mode) - but still the exif values show 1/3 stops. However this does not correspond with the luminosity changes. If HG-Wizard would be enabled, it would compensate for changes that are not there in reality (only in exif) thus making things worse.
Just use the visual deflicker at the end of the workflow if there is still need to smoothen anything.

That was very comprehensive, thanks!

I bought this camera (the Sony RX100v) primarily as a small companion camera to shoot timelapses with.


Its timelapse app was one of the highlights for me. Im guessing its AE tracking feature works better than other cameras in Aperture Priority mode, since presumably it wont be confused by a momentary change in brightness (e.g. from an oncoming car). But otherwise, what am I missing when I shooting in its AE tracking mode as opposed to doing Manual mode and adjusting exposures manually (by 1 stop increments, for example)?

I just registered on this forum which particularly captivated me. I would like someone to help me answer my question.
I recently wanted to buy a portable compact camera to take pictures during my vacation. Sony is the “go-to” brand for cameras, I personally like Sony RX. Then the problem is coming, as the title indicates, Sony RX100 III vs RX100 IV comparison, what’s the different?
Thanks for the help.
