Live view tethering of Q

Hello, long time since I was here although Iíve always followed this section. Iíve recently taken up microscopy and would like to use my original model Q to photograph specimens through the trinocular tube. What Iím asking is does anybody have experience of using a Q with a monitor as the focusing aid?
Can my Q be connected to a monitor and be used in this way?
Is there anything I need to know?
Thanks in advance, kind regards, K33F

as far as I know , the answer is NO.
All earlier Pentax's cameras would feed HDMI out on playback only.

You can connect to a TV monitor with AV cables.
I did this to test the functionality of a Q with a broken screen once. HDMI will not work however.


Can I hook up the camera to an AV device and leave it connected while shooting pictures?

Yes. To view an image on an external monitor while capturing it, connect the camera to an AV device with a video terminal. You cannot output images using the HDMI terminal while capturing pictures.

The AV cable will give you video composite quality ( copy of the image on the back LCD screen ), very low resolution.
Not much use for anything. You need HDMI out quality.

Thanks, Iíll pursue that route, hopefully it will meet my needs. The camera on top of my trinocular would just be so high that I wouldnít be able to stand tall enough to focus normally.

Thanks, Iím hoping it will be sufficient just to confirm focus. I will be doing all my composition using the binoculars and getting rough focus, then using the monitor to confirm the camera has got focus. Iím happy to experiment, the ultimate aim being to achieve a parfocal arrangement which will simplify things greatly.

Can you lower your microscope setup (on a lower table/platform or even the floor)?

Lol. Iím 70 years old, bending that low and standing up again forty-leven times an hour would finish me off in a week. Itís bad enough using a cellphone camera mounted on a flat adapter. I wouldnít need to do it at all but the cellphone camera is limited in its usefulness. Iíve established that I can produce an image, but now I want to produce the est image that my resources will allow. I canít justify, or even afford a top end DSLR with tethering, so my Pentax Q solution is the best I can afford. I have to try it, even if itís not successful. At least I will have tried my best.

For ref: I hooked up an external tilty LCD monitor via the av wires from a Q for live view and it kinda works ok for focussing in conjunction with the Qís zoom function

Or low tech use a mirror. I have this small one on a bendy stalk that slots into the hot shoe and allows you to view the rear screen from an angle. It was an accessory that came with a very old school selfie stick for little point and shoots back in the day.
