How do you lock focus and exposure independently w/o the shutter release button?

Assign a back button to auto focus, and half-depress the shutter button to lock exposure. How to assign a back button for auto focus is described in the manual. See p. 110 and following pages.

There is a button on the back of the camera body which does this - AE-L (auto exposure lock)

No. But after holding the button for about 3-5 seconds into the exposure, when you let go, it will still continue and then end the exposure when you press the button again.

The lock button is used when you have your camera in manual mode, using the "bulb" function. That means when the camera is set to this function and the button is locked, the shutter while stay open for as long as the button is locked, or the abilities of the camera are reached. This is usually done when taking longer exposures in low light, or astrophotography. If you have ever seen a picture of a stream where everything is clear except the water seems to be blurred in motion, this is how that is done.

Yes. Not something I would use though.Depends on how fast your finger pushes the shutter and if you are focussed on subject already. Pre-focused or manual focus the shutter opens as soon as your finger pushes the button down.

You can either manually hold shutter button or 'lock' it down. This is on the receiver on (attached to the camera), NOT with the wireless remote.

I have found all thebuttons to work, however I tend to only use the shutter release and occ. the selector wheel. The clock mode on the LCD is handy. I made a point to learn what they all are for when I first installed it, but have forgoten them since I dont use them any more. I still love this grip with the extended battery life and relocated shutter release.

Holding the button down halfway allows you to focus on an off-center subject. For example, to focus on an off center subject, position that subject in the center of your screen and press the shutter halfway down to freeze the focus on that subject. While continuing to hold the shutter button down halfway, recompose the image on your camera and press the shutter button down the rest of the way to take the picture. If, on the other hand, you want to focus on the subject already at the center of your screen, just press the shutter button down completely and the camera will focus on the object in the center of the screen while taking the picture.

I have a D300s and D800. It works the same as the normal shutter release on both. For Bulb mode exposures I like to use the MC-36 u trip the shutter to lockup and a few second later trip the timer and u can pre program how long u want the shutter to remain open. And don't have to hold the button. Automatic. I use the witless remote out to 30 seconds. The witless device works great for me.

No, you do not have to hold the button down. Press once to start exposure, press again to stop. BTW...Might I suggest the RC-6 rather than the RC-5 remote. The difference is that the RC-5 has only a 2-second delay shutter release, whereas the RC-6 has a switch to change from 2-second to immediate shutter release. A much better choice in my opinion.

You cannot. All you can do is half press the shutter button to force it to become ready for the next shot. There's no option to completely turn off the feature like the older Z cameras had.

Unless you select "release shutter without lens" it will not work, as there is no electrical connection to the camera. Peaking will work

There is a lock/button on the side of the barrel. Don't push or press in this button. Instead, push it along the barrel, i.e. the direction along the lens.

On my camera I am able to choose "Bulb" setting which allows long exposures. Using my remote I activate the opening of the shutter, using it again closes the shutter. There is only one button on the remote. Remember to point the remote at the infrared receiver on the camera. On mine I had to point at the front of the camera.

It has the vertical shutter release and a switch to turn the vertical shutter release button off

Built into the shutter release button is a slider button thingy. You need to set that so that the white dots meet. then it should work.

There is a lock function. Not 100% sure if it would be for what you need it for but I can confirm there is a lock function that allows photos to be taken continuously back to back until you take it off
