Sony α7R II. This is my go to camera for this type of photography. I normally shoot at ISO 50 and I frequently use an ND filter.
Sony Sony FE 70-200mm f/4.0 G OSS lens for close ups.
The Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS lens.
The 24-70mm f/2.8 Carl Zeiss T* Alpha A-Mount lens.
72mm 0.6 Neutral Density filter- I use this on most shoots so I can photograph at a slow shutter speed like 1/60th-sec so you get that nice prop blur.
My pilots log book. I don’t log the flight as the PIC (Pilot In Command) but I find that logging is a great way to keep track of the photo flights.
Think Tank SD card wallet.
Sony SD Memory Cards-I normally carry 3 or 4 fast 64GB cards.
Sony Alpha to E mount LA-EA3 adapter
77mm ND filter.
Think Tank battery wallet with 2 Sony NP-FW50 batteries.
My camera bag is normally the Domke F-3X it’s a small bag with several pockets.
I carry the “Remove Before Flight” on my bag for no other reason then to see if the pilot is paying attention:-)
