Unfortunately there is quite a lot of information missing in your question in order for me to accurately answer it, but I think I understand the general gist of what you’re trying to do so hopefully this quick reply helps.   I think that the biggest problems you’re probably experiencing in this scenario (photographing birds) are: The ...

Nikon DSLRs do not play well with M42 lenses, as flange focal distance (46.5 mm) of Nikon F-mount is longer than on the original M42 cameras (45.46 mm). The lens was designed to sit closer to imaging plane (film) than it can physically reach on your DSLR's body, and this robs the possibility of focusing anywhere near infinity; the lens can be focused only in ...

In manual mode I can not select the aperture but only shutter speed and exposure. That's correct. The M42 mount doesn't have any provisions for the lens to interact with the camera in either direction, so shutter speed and sensor sensitivity (ISO) are the only things on the body you'll be able to adjust. Aperture is, obviously, on the lens. The ...

I have several of both types, and while the exif data is fixed and therefore of little use (other than knowing i was using a legacy lens), the focus 'beep' I am able to get with the AF adapters on legacy lenses really does help me get the photos in focus. It also enables the use of both manual ...

I suppose there's a simple way. You could bring a measuring tape or a long ruler down with you underwater. Hold the ruler out in front of the camera and observe at what distance does the markings of the ruler become clear. That should give you a fairly accurate measurement of the focusing distance in water.
