I haven't played with it enough to tell you how to get the most out of it. The camera has a depth-of-field indicator in the information menu. So, focus will be more critical.Īlso, I'm not sure if the camera maintains its focus point if it is turned off between shots. As light decreases and the camera uses a wider aperture, depth of field decreases. with the infinite scan length data, and to estimate the dose typical for a. This method works best in bright light when the camera will use a higher f-stop. Exposure was measured according to the methods of AAPM TG-111 (AAPM 2010). Since focus is less critical when zoomed out because there is less magnification of the image than when zoomed in, everything up to infinity will be in focus.

Put the camera in manual mode turn on magnification for manual mode in the menu zoom all the way in on the subject focus manually and zoom out. The easiest way to focus manually to infinity is to chose an object more than 30 or 40 feet away. Have you tried this Alan over the magnification method? I choose the color red and it seemed to work well. In my experimentation today it seems to me that Focus Peaking in manual mode is the best way. (DOF 20 ft to infinity) But, shooting at that focal length in light so low it won't focus doesn't seem like a good idea. At the telephoto end, the hyperfocal distance moves out to about 40 ft.
Focus on something around 10 ft or more and you are done. Everything from 3 ft to infinity will be in focus. At the wide end f/2, the hyperfocal distance is a bit over 6 ft. With a small sensor cameras, you don't need a precise focus at infinity. That's how I use my ultra wide MF lens (the recent Laowa 7.5mm F2 MFT lens I'm not sure exactly the TG-5 does in those modes, but focusing at infinity is unlikely.įor now what I am doing is to use the center AF point and focus on something near a light source (such as street light) than recompose, This work most of the time but manual focus to infinity is the best solution, I think. Even in clear water, visibility drops off quickly. It's intended to focus at relatively short distances. Or will using "underwater wide" or "underwater snapshot" scene mode focus at infinity? Long press "ok" button only work in live composite mode or in all mode?Ĭorrect, that only works in live comp mode. The most practical solution is to focus at infinity. I know TG-5 has manual focus but to MF every shot is too much trouble. It is already improved from TG-2 which I own for 4 years but extreme low light (street light at night) is still a hit and miss TG-5 low light autofocus is unreliable to say the least.
