I have Sony NEX-5T. Here are some lessons learned, as follows:

Camera settings:
1. I use 3:2 aspect ratio for stills for a key reason -- it uses the WHOLE sensor for maximum resolution!!! For video, use 16:9 .
2. Turn graphic display to ON.
3. For help leveling, turn on-screen level display ON. If your gimbal level is slightly off a quick fix is to shim one side of the camera base with tape. I use aluminum HVAC tape.
4. If you like histogram, it can be shown and viewable in your FPV display.
5. Turn digital zoom OFF.
6.. I set color to VIVID and shoot RAW. Vivid just looks good in monitor; it does NOT affect RAW files but it does affect jpegs and video "look."
7. For still photos: Use shutter speed of at least 1/500 sec.
For video, use 2x the frame rate. Example: for 30 frames per second video, use 1/60sec. shutter speed.

16-50mm Sony zoom kit lens:
1. If you are shooting JPEG, digital zoom of 1.5x may be activated by default even if you have digital zoom "off." Solution: select RAW file type and process in Photoshop.
2. Zoom can be activated remotely with modification. Secure wires carefully to avoid breakage. Stealdesk used a strip of 3M VHB and it worked great!

Batteries:
1. Sony batteries are heavier than generic like Wasabi Power. Standardize and use one battery model if you want your gimbal to stay balanced when you change batteries. I like Wasabi from Amazon. You could also add weight to lighter batteries to equalize the weight if you mix and match battery brands.


Infrared remote:
1. Pick the smaller infrared remote emitter. Mine has a surface mount IR diode. Attach to camera using double sided tape such as 3M VHB from eBay. Point the IR light directly into the remote shutter release located in the NEX camera -- it's on the front of the grip.
2. In camera menu, you must select "remote" to activate the IR shutter release.
