one of the best cameras on the market. I was between this and the Osmo Action 5 pro. Osmo won me over and I'll tell you why...

First, let me say that before I made the purchase, I had the Ace pro 2 in my hands, which a friend lent me for 2 weeks and I used it quite a bit.

WHERE THE OSMO 5 EXCELS - WHAT I WOULD LIKE THE ACE PRO 2 TO HAVE.

1) The Osmo has front and back OLED screens and every time you want to take a quick selfie photo you don't need to open and close the foldable back screen. In fact, even from the small front one, you can operate the menu.
2) The Osmo is much smaller in size, and looks higher quality in plastics and construction, without meaning that the Ace pro 2 isn't good. You just feel it lighter, more hollow.
3) The Osmo's battery is bigger. It lasts more hours, charges quickly, makes life easier.
4) It has 47GB of internal memory, which is very important.
5) It shoots 10bit colors while the Ace pro 2 shoots in 8Bit.
6) Much lower purchase cost than the Ace Pro 2. I don't understand why it's such an expensive camera. It in no way justifies the price difference it has from the Osmo 5 pro which is better.
7) Better feeling shutter button, it's easy to press, while on the Ace pro 2 it needs force. The opposite happens with the camera's power button.

WHERE THE ACE PRO 2 EXCELS

1) The Ace pro 2's screen, being foldable, helps you shoot low angles without having to bend your head all the way down to see what you're shooting.
2) It shoots 8K resolution, which is insignificant or I would say unnecessary for the needs of most users.
3) It has a detachable cover for wind noise reduction.
4) You can press Pause while recording a video. Maybe the only thing I envy and the Osmo doesn't have.
5) You can apply image filter effects through the camera. Insignificant, but convenient for those who don't know or don't want to deal with video editing on a program either on the phone or PC.
6) It shoots slightly brighter videos at night than the Osmo 5.

The conclusions are yours. I think it depends on everyone's needs which camera suits them. But for me, both are top with a difference, it's just the price difference that makes the Ace pro 2 lose points.
If you get both in your hands, you'll understand that the Ace pro 2 is not worth its money when it has the Osmo against it.

I bought it to replace the first-generation Insta360 Ace Pro, which left me very satisfied, and while the camera is improved compared to its predecessor, I ultimately had to get rid of it because Insta360's service is laughable and pitiful.
In terms of dimensions, it is exactly the same as the Ace Pro 1.
The external differences are mainly as follows:
1) The front microphone, where now there is an option for either a plastic waterproof protective cover for use in water or a windslayer that significantly reduces wind noise.
2) The screen, which is now slightly larger in size and offers much better resolution.
3) The lens protector, which is now removable and not glued on like in the Ace Pro 1. So if it gets damaged, you can replace it very easily.
However, here comes its first negative, since now there is a chance the camera will show condensation during use, and this is why the newer batches come with a small rubber ring that "seals" the gap between the camera body and the lens protector, but it comes off quite easily. Fortunately, the package includes a second one as a spare, but keep in mind that most Insta360 models have condensation issues.
In terms of image and sound quality, the differences compared to the Ace Pro are notable only in the following:
1) Wider field of view. The Ace Pro 2 records a wider field than the Ace Pro 1. This means you can capture a larger part of a landscape or the background behind you. I would say that in terms of field of view and fisheye effect, it is somewhere between DJI and GoPro.
2) Cleaner videos in low light. Videos in low light show less noise and more detail than the Ace Pro 1, which already had excellent performance in this area. However, the colors are excessively warmer and the lights look blurrier, with a "halo" around them.
3) The sound is clearer than the Ace Pro 1 and the external protector helps a lot, but I think it still has a long way to go to reach DJI quality.
4) It takes better photos and its zoom is much higher quality than the Ace Pro 1.
On the technical side, it has an improved sensor, which remains the same size as the Ace Pro 1, very good stabilization, longer battery life, and is easier to use as a dashcam.
Otherwise, we're talking about a camera with very good video performance up to 8K, although if you choose the highest resolution you will notice a lot of cropping.
These improvements, however, although noticeable compared to what we are used to from GoPro and DJI's annual models, do not make it a camera you absolutely must get. If you have the AcePro 1, it's better to wait for the 2025 model (Ace Pro 3?). I only wish I had listened to my own advice...
Overall, it was a model with quite a few manufacturing problems, the most important, as I mentioned above, being the fact that it showed condensation and required an external rubber ring around the lens.
Mine, however, had another equally serious problem: a crooked lens, resulting in the videos coming out quite skewed and I couldn't fix them either through Insta360's software or through DaVinci. I contacted the company and after 1 month of daily communication, with wetransfer being on fire since they kept asking me for videos in various settings to "verify" the problem, I was forced to argue with them and make them send me a ticket so I could send it in for inspection, but they threatened me that if they determined there was no problem, I would have to "compensate" them in order to get it back. So here arose a matter of trust and I decided to get rid of it. I should note here that I have had interactions with the customer service of both GoPro and DJI and the results were as follows:
1) GoPro Hero 10: the video had a barely noticeable shake on turns and after 1.5 years of use (GoPro gives a 1-year warranty), I sent a message to GoPro and said that it might have a problem with the gyroscope. Their response: within 2 hours, a return ticket and within 2 days a message with a tracking code for the refurbished replacement camera! They didn't hassle me for a month, didn't threaten me, nor did they wait for the camera to arrive. And all this while the camera was out of warranty because I had it for 1.5 years.
2) DJI Osmo Pocket 3: the camera showed condensation and the gimbal behaved strangely if you turned it off and on without removing the wide-angle lens. Within 15 minutes, and just upon mentioning the condensation, they had sent the return ticket. I told them that Christmas was approaching and I needed it urgently for a trip and they promised to do everything they could so I could receive the new one as soon as possible. The camera arrived at their offices in about a week, they immediately sent me the tracking code and DHL delivered the replacement camera 1 day earlier than expected. When I opened the box, I found that it was not refurbished, but brand new, sealed, with all its accessories!
Will I choose an Insta360 camera again? Yes, because they serve me well in terms of features and I have already ordered the Go3S, but instead of letting it sit for 20 days before I use it properly for the first time, I will do very strict checks within the 14-day return window, so I can send it back as soon as I notice something, to save my money. Also, after my experience with their customer service, I will keep an eye on the newer GoPro and DJI models, mainly because they have better customer service.
