I disagree.. I love the P4/6K formfactor. Its one of the reasons I went with Blackmagic. They produce cameras that can function without adding anything but a lens to them.
The Ursa Mini line is kind of boxy. But add their shoulderrig, EVF and you are good to go. Nothing more.
I hate rigging. It slows you down. You want to do handheld, then you will have to add this and that. Then gimbal, you have to remove this and those.. Then you want to go to tripod, and you will add it all again but add even more stuff.
I like my rig simple.. And blackmagic provides that. The "modularity" that RED introduced is never really modular. You simply add their back xpander with Audio, SDI and batteryplate and you leave it on forever. Then you move the display around from job to job.
The ridiculess rigging on the Pocket series is always overdone. Dont get me wrong. I understand
some need v-mount batteries that last 8 hours. But on SoMe (Facebook, youtube etc) its seems like everybody and their dog is adding these things. They do it because they complain about battery life. Well. Buy good batteries instead. My simple rig lasts 50-60mins. Then I will change the battery and move on. Takes about 30sec if I am bad. I like this better than adding 5kgs of rods, battery mounts, batteries, cables, cages, wireless focussing tools, screen etc. Then with all the addition weight, now you cannot see the screen. So you can barely get into the menu of the camera which also slows you down.
The one thing I think the Pockets are missing is a built-in EVF. Fuji GFX style. This would allow a 3. point of contact with the body and not hold it out in front of you like an iPad. I hate this pose as it introduce so much micro jitter. I like to hold my cameras as teddy bears.. Close to my body. Cuddle them. They should be an extension of my body, not some tool I hold.
No camera shape will get you jobs. Your work and marketing of said work will.
