I have been reading a lot about Gear 360. Here are what people say (compared to Ricoh Theta S):
- Best picture and resolution
- Has an SD card (Ricoh only has 8 GB internal)
- Many options
- The app only works with some of Samsung high end phones. The basic modes can be changed directly on the camera, but forget about stuff like time lapse interval (important for Mapillary) and image resolution. The app is necessary to get any firmware updates to the camera - one should already improve image quality.
- Ball shaped - does not fit into a pocket.
- Much more visible stitching lines than both Ricoh and LG.
I have not been able to dig up reliable information about time lapse, neither timing nor resolution. I don't know if it will make a video instead of jpgs, only make video resolution or it is full resolution pictures.
I will say: If you have one of the supported phones go Samsung. Else go Ricoh Theta S.
Edit: While Samsung has this very closed platform, Ricoh has a completely open REST API, so developers can easily write a lot of cool software. We could hope that Mapillary would integrate with this API!
http://360rumors.blogspot.dk/2016/06/preview-of-samsung-gear-360-vs-ricoh.html claims that the Gear 360 images will only be stitched together if you have a Samsung phone - i.e. it happens in the phone and not the camera. Such a mode would definately make it possible to shoot time lapse far faster, but for a good Mapillary session you might have to keep the phone stitching all night?
I lack a lot of info about Gear 360, but the close ties to a Samsung phone does it for me. I will order a Ricoh Theta S today.
