do you know which cables will work with it? or none at all
No Nikon-made cable releases will fit as there is neither the MC-DC2 style connector nor the 10-pin connector. A device connected to the USB-C can probably control the camera (I haven't tried it with Camera Control Pro 2) and thus a remote trigger could be made based on USB-C, but I imagine it would be expensive compared to the cable releases that we are used to.
What bothers me about the ML-L7 is that it can only trigger single exposures, not bursts. For certain kinds of astro applications, I would prefer to trigger the camera continuously, for example, to capture asteroid trails. What ML-L7 can do is turn on and off video recording, and access menus via the function buttons and arrow keys. It can also use the power zoom but there is so far no power zoom feature on any Nikon FX Z lenses.
I find the very bright self-timer light obnoxious and will try to express my wish to Nikon (in my long list of feedback) that it can either be turned off or exposure delay mode be added in a firmware update. For now I will use ML-L7 for tripod-based shots when needed. I would like to see Nikon standardize on these ports and accessories (and memory cards) but things are as they stand.
The camera's autofocus and VR capabilities are wonderful. The buffer is also very large in HE* raw mode, well technically the actual memory buffer may or may not be large but the 24 MP HE* packed files are so small that in practice a ridiculous number of shots can be fit into the buffer before the camera is slowing down even with dual-card writing in use.
The LCD screen is annoying because if I am having the camera strapped around my neck, to go for a low angle shot, the strap tends to land on the screen and the EVF sensor also has a tendency to switch from the LCD to the EVF if I am holding the camera close to my chest (for better support when hand-holding), so I have to take the strap off my neck, place it so that it goes under the screen and then use the camera from the low angle. Also to go from angled to the basic orientation where the LCD is behind the camera and open to viewing, a complicated twisting operation is required. For vertical shots depending if I'm going for a high or low angle shot, I need to turn the camera in a different orientation (grip up or down). All these things make the camera harder to use than with the two-axis tilting mechanism of the Z8 or Z9.
No problems using the camera with gloves on. I haven't tried the glove mode of the touch screen yet, but it has worked well in previous cameras that have had it. I just don't need to use the back LCD touch capabilities all that often and probably my current gloves are not an ideal fit (too much air space) for touch screen use. I should try to find more suitable gloves for camera use as the winter comes.
