a, sorry. I was assuming it works the same way as in DSLR s. There TTL works in M mode.

Would not agree. For rectangular (non fisheye) lenses a larger port diameter will be better. A diopter on the lens might improve sharpness just a bit.

Also remember that the lens will focus on the virtual image, which is typically at about 1,5 times the port diameter. Setting the focus to the expected subject distance before diving will not be in focus if you use the distance scale.

Also curious why you can't use af, you can use back focus to a specific distance underwater and leave it there

Quite a story Bruce! (Didnt read it all) Welcome back. My and my wife's parents would disown me if we would ride motor cycles.

so if you want to use TTL : mode switch on TTL

light level control dial up and down to perform minor adjustments.


AV (aperture priority) is not very useful. If a strobe is used, it either fixes the shutter speed at the sync speed, or it will attempt to adjust the shutter speed to get a normal exposure (which can mean too long exposures.

In bright conditions, you might end up with a natural light shot with just a hint of strobe.

better to use the manual mode in the camera to have more control over the shutter speed.
