The GoPros and DJI Osmo Action and DJI Osmo Pocket (camera on gimbal) are great entry-level vlogging platforms but they have pluses and minuses. The GoPro look is kind of fishy though and you there's no way to frame the shot (no vlogger-facing LCD). The DJI Osmo Pocket FOV is a little narrow for vlogging and the gimbal doesn't fix z-axis (up and down) motion most common when walking, leading to a slightly "on a boat" look. And that category in general has various issues about battery life, audio support, etc... along with the typical limitations of a small sensor camera.I have to ask, since I know nothing of this world, but what you are talking about, aren't GoPros up to the task? I think their image stabilization is mostly digital (?) but from what I have seen looks great and for blogging purposes does it really matter if you lose a bit of resolution to support that digital cropping? Plug they are tiny, they have a form factor and a ton of accessories that make them ideal for mounting on just about anything for bike riding, traveling, etc., the newest ones I think are water proof without the housing (?), etc.
Anyway, wondering why some of these "action" or "sports" cameras might not be simply a better form factor than a more traditional camera body for these types of videos.
The new Sony and Lumix G100 appear to be positioned as step-up cameras from those setups, with improved image quality from larger sensors, better low light performance, better audio, better battery, and dual use for stills. Overall, it's a smart move, and positioned between the action cams on the low end and "real cameras" like the G95 on the upper end. I think that's part of what drove the price point target.
But personally, I would have preferred to see the G100 move a bit upward in price (and at risk of encroaching on G95 pricing) to incorporate OIS and think that product features (shutter type, OVO audio, weight, selfie features, etc..) could have provided the necessary differentiation. But they've likely done a lot of market analysis on most desired features and pricepoint for this market. For the sake of the brand, I hope it's a success.
