My FS7 is built usually with for shoulder work with my 'EVF' (DP502) so far forward that I risk seeing it with a wide lens. My camera is lovely on the shoulder to operate.
The NGO thing I did in zambia the camera was just way too big - it was really hard to get in and out of the rental car, shoot from the car, or be low profile in any manner and heavy with Vlock and rig.
For my second trip there I tried a different approach with the cam not supported by the shoulder: EVF and side handle and plastic 18-200 with stabilisation. And it did work. (yes 80% of the work was on sticks).
Compact build with custom monsoon cover. https://www.instagram.com/p/Bsvmq4vF967/?utm_source=ig_web_button_share_sheet
Prefered build? No. Useful in some situations? Absolutely.
Is the bag an optional accessory . .
