Thank you all for your answers. :)
So, I understand there is nothing to worry about.
Anyway, I've decided to buy some used, cheap DSLR body only for that - this rank was very helpful. Canon EOS 1100D seems to have good parameters / value factor - I've found rarely used, 1.5 year old camera, even with kit lens, for about 200$ on local auction.
In addition, it offers very handy computer control (which I miss very much in my K-50) and probably mirror lock-up, that prevents microscope shaking, that was a bit problem with Pentax. Especially computer control may be handy from time to time.
Once again thank you for answers!
Best regards

You're right - my question might not be clear. I mean the second option - half an hour is a time that camera is attached to microscope, with the same image. During that time I make photos, change camera settings, try to set focus with live view, do so things on the computer - but all that without removing or turning off the camera. Anyway, it might be a good idea to turn it off more often.

Hello :)
I'm a new user of Pentax K-50, as well as I'm in the beginning of my journey with microscope photography. So, I'm experimenting a lot, trying to find the best way to connect my camera to microscope.
As my microscope has trinocular head, I started from removing objective from DSLR, attached T-2 / 30mm adapter (like that one - simple tube, no optics inside) with pentax-k ring to the camera body and put that directly into trinocular head.
Don't know if it matters, but microscope is using LED light (not sure power - 1-3W perhaps?) and its optics is corrected to infinity.
I'm trying to make some pictures, example of fruit-fly, with microscope 4x-10x magnification using reflected light, coming from "external" 3W led flashlight, highlighting specimen from top.
My question is - is the long (let say half an hour), direct exposure of DSLR matrix for the same, not moving picture (for stacking), with quite a bright light, can cause some damage to it? Obviously I do not beam the light directly to the matrix, but...
Yesterday, when I've removed camera from microscope, for some seconds after I saw on preview the picture of fly - not sure though if I didn't accidental click some button or mode to hold it :-/
Best regards and thank you for replays :)
