Incidentally I was in discussion with a video nut (friend) yesterday about the jerking caused when camera is fighting its onboard image stabilisation that he gets when panning. Of course we went through the moving picture not moving camera debate. But he showed me a video of him cycling through Indian streets (traffic, cattle, pedestrian mayhem) and his GoPro camera strapped to his bike was absolutely rock solid stable. Even on potholed streets, swerving around moped and scooter maniacs …even when he hit a grate in the road and fell over the handlebars….it recorded it. without any issues. So picking up this theme of why haven’t Nikon, Sony, Canon et al matched the iphone? Why isnt the image stabilisation on DSLRs as good as a go pro?

I have a Canon XL1S videocam with optical stabilisation - it is also rock solid when panning or tilting. The GoPro & Iphone don't (as far as I know) use mechanics - they work by cropping the image and shuffling the viewed area around in the limits of the sensor electronically. Obviously this is faster and doesn't suffer inertia issues of moving parts - the VR lens assy and its associated gyros in Nikon lenses. The XL1S does both - it uses a variable prism in the lens followed by image analysis on the CCDs (it has 3).

If your explanation of how go pro &phones handle stabilisation is correct then it sort of adds weight to the op that cameras are lagging behind phones in some functionality. I don’t know how dedicated video cameras handle stabilisation v panning but on DSLRs the stabilisation fights against the camera movement generating (albeit minute) judders. You have to be an anorak to see them (like my mate) but I have noticed occasional frames losing sharpness when following birds in flight. On the Sony large lenses designed for wildlife & sports you have the option to switch off 1) horizontal stabilisation or 2) vertical stabilisation or 3) both…which to me suggests a recognition that their camera movements can be a battle with their stabilising system. When I switch off horizontal stabilisation I see less ‘rough’ frames….the ones I have, are clearly me!!

I surmise that the issue is the slowness or lag in the DSLR system - the gyros have to sense the movement - tell the CPU - CPU tells the vr coils to move the lens - they react and you get the judder. Maybe small fractions of a second but way slower than electronics. But then the stills camera was never really intended for video! Video cams have this buttoned up but are useless at taking stills - 6.5 seconds to record a still on the XL1S! Yes I can run the XL1S in frame mode at 25 fps and get reasonable images. I have tried using the iPad for video - it is OK on stabilisation but rubbish zooming in and out - like big jumps! Smart phones for communicating, DSLRs for stills and videocam for movies. Simplez really!

I tend to agree with that summary, although the newer Sony cameras, with Sony’s foundation in video, are excellent at video. They just need to get the buttons in ergonomic positions and slicker menus. I didn’t appreciate that was how phones and go pro handle stabilisation. However, accepting your categorisation and each items strengths and weaknesses, it does support the OP that there are some features in phones (eg better stabilisation) that camera manufacturers are missing out on.

More a case of using a screwdriver as a chisel!
