The bag is an F-Stop Loka with the extra large ICU (internal camera unit). The F-Stop website doesn't list the extra large ICU as an option for the Loka but it does fit, although there's not a lot of space left in the top compartment. I also have the large ICU, the dividers in the picture are from both the large and extra large ICUs. 

Mounted on the waistbelt are pouches to hold a flashlight and phone, I got these from ebay.  Not pictured are two F-Stop redfern accessory pouches that mount to the sides of the bag, I use these for carrying food.

1. Nikon D800E with DK-17 magnifying eyepiece, hoodman hoodeye eyecup, MD-B12 vertical grip, RRS L bracket, Nikkor 14-24 f/2.8

2. Sigma 35mm f/1.4

3. Gitzo GT3532S, Manfrotto 405 geared head, Hejnar adapter plate, RRS screw clamp, Optech leg pads

4. Lee SW150 filter holder with custom baffle system to eliminate reflection issues 

5. Lee SW150 adapter, this allow the SW150 to be used on other lenses besides the 14-24

6. Lee 67mm mounting ring

7. Apple iPad

8. Neoprene lens cover, the normal cap wont fit with the Lee mounting rings on the lens

9. Spare guide rails and screws for the Lee holder. The CPL filter is thicker than the other filters and requires different guide rails. I only use the CPL on waterfalls so I swap the guides when needed

10. Sandisk and Lexar 16 and 32gb cards, LensCoat wallets

11. AA battereis

12. Nikon EN-EL15 batteries

13. DTSE 3900mah batteries. High capacity batteries that fit the Nikon grip

18. Pouches for Lee SW150 parts, remotes and DTSE batteries

19. Promote control. Programmable timelapse and bracketing controller 

20. Yongnuo wireless remote

21. Aperture wired remote

22. Fenix LD20 flashlight

23. Red filter for LD20, red light doesn't harm your night vision like white light does

24. Fenix TK-45 flashlight (760 lumens) I mainly use this for bouncing light off trees behind the camera to light paint objects in the shot

25. Kendrick dew heater controller

26. Kendrick dew heater strap 

27. Lowepro gloves

28. Compass

29. Lenspens
