When zooming from wide to tele in auto the camcorder adds auto gain in the picture.
But how do you do this when filming in manual? When start zooming in and the picture gets darker... do you use the gain switch to get it brighter? how do you do this to have a "smooth" zoom like in auto mode?

When the camera is in manual mode, you can still set the gain to auto by pressing the gain/iso button.

When you set any of iris, gain or shutter speed to auto the camera is now in auto with the parameters in manual at the values choosen. You can set the iris and shutterspeed manually, gain in auto and use AE shift to get the exposure you want. The camera will then maintain this offset. Most Sony cameras work this way. In auto most Sony's over expose about 0.5 to 0.7 EV so you may need to compensate by setting AE shift to -0.5 EV or so to taste. I have AE shift set this way on my NX30U and NX5U so that when switched to auto anything the setting is used. Both the NX30U and NX5U lens also ramp so I try to keep iris on the NX5U at f3.4 or smaller so that I can zoom without the ramp if my gain switch settings are not set correct for the scene I can switch to auto and know that it will have the AE shift set.

Sony's are brilliant like that! I leave my cameras in full auto and when the lens goes on it will automatically discover that it cannot communicate with the iris, IS and focus so it will switch those to manual for you but whatever it's able to still control in auto it will do so without you touching a thing. The firmware is very well programmed ... if you try to execute say, touch focus on a manual lens it will simply give you a message that you cannot use that function.

So Tom ..switch the camera to full auto, use your manual lens and then whatever the camera still can control it will do for you BUT you still have the option to turn each of the remaining auto functions off or leave them on.
