1. Is inside mechanicly adjustment for manual focus directly to ring of camera (not only command to switch Manual/Auto Focus)?
There is a turn knob on the front left (looking from behind) that is connected via a belt inside to the manual focus ring
2. Which brand of 0.5 wide lens is in package, is better then original Canon WD-58?
The lense is a Digital Optics .45x stating it does 180 degree viewing. I feel the Canon lense is better, but have had no real issue with this other then some vignetting when fully zoomed out. Which Equinox said i would have none of.
3. Do you have 2.5" LCD monitor? On other rig I have 4" and is big enough. What about view angle, up/down? Where is accumulator for LCD and what type A/h?
Yes i purchased the 2.5" LCD, I mostly use it to set my zoom to cancel the vignetting when i start out. Other then that I use the camera's viewfinder as a quick reference to what I am shooting at. The view angle isn't to bad, but it ships with a hood ontop. Not sure what you mean by the accumulator. The LCD hooks up to the TV out on the camera and is powered by a seperate 9V RC car battery.
The housing itself is great, but the customer service leaves much to be desired. It is a large item out of the water, but in the water it flows beautifully.
If you need any pictures of the setup let me know or if you have any other questions.
