Real-time IR preview with DSLR using Zigview

PQ23 · 22nd July 2005

Has anyone tried using Zigview (a Digital Angle Viewfinder) with IR filter fitted on? If it works, taking picture with IR will have real-time preview.

I have tested zigview with a remote control, and I can see bright IR beam from Zigview LCD. I don't own an IR filter, not sure if it works on it.

Any feedback will be appreciated. Maybe, if any volunteer wants to test this, we can arrange for meetup.

err, i dun think it works this way, you still have to let your DSLR open its shutter then you can view... the zig view is just viewing off the mirror reflection instead of the actual readout from the CCD/CMOS.

DCA is correct, whatever you can't view from your viewfinder, you won't be able to view with the Zigview - the Zigview uses a mini lens which captures whatever you see in your viewfinder.

I thought our eyes can't see IR light, but Zigview's cmos/ccd can see? That is why I can't see the IR light transmit from a TV remote control, but I can see it thru the Zigview LCD.

Similarly, we can't see the IR light from the viewfinder with IR filter on, but Zigview should be able to see it. Correct me if I'm wrong.

When i try liao then i tell u, if it works.

Don't think your aperture is bright enough for the Zigview to capture.

I thought the Zigview would use something like the camera sensor so it COULD see it?

I think that when PQ23 refers to preview, PQ23 refers being able to see through the IR filter with the Zigview attached, not the actual preview of what the camera's sensor sees

which makes it easier to shoot IR, rather than composing then screwing on the IR filter, or shooting blindly

Theoretically, you should be able to get the IR preview on the ZigView (I don't have one, so I can't verify). The filtered image on the camera focussing screen consists mostly of IR, which the ZigView should be able to pick up easily.

Well lets wait for the next IR outing then we can test out

I have the Zigview and I'm sure most of you in this subforum have IR filters

Let our powers combine :P :P

Del_CtrlnoAlt · 22nd July 2005

i have another thing about it... dun think the Zigview is slow enough to allow much ambient light to brighten the image when the view itself is dark... you already have problem viewing zigview if the pic is dark, so now with a IR filter, i dun think can view also...

adamadam · 22nd July 2005

How about if you play around with the exposure control on the zigview? (if there is one)

Why wait until the next outing! try now now now!!!!!!!
hehe *waits for results*

Yes, that's exactly what I meant.

Want to join in our shoot this Sunday 24/07/2005 to test it?

have tried with the kit lens+IR filter+zigview.

yap! you can see the outline of the building and trees, but it's barely visible.

unless the place you shoot is super bright and sunny.
it does give you a rough idea on what you are shooting, instead of shooting blindly.
