Excuse-me for the delay.
Indeed, one needs a tripod or any car roof/post/rock for long exposure.
The camera needs to be 100% steady.
You sometimes make minutes long exposures:
If it’s really dark like a black sky with stars (in that case they will produce circled lines)
or if you wait for a special event like thunder.
Great possibilities…
Here a comparison with features founded on a Samsung Galaxy S23:
Flash: Disable, Auto, On
Timer: Disable, 2’, 5’, 10’
Size: 3:4, 9:16, 1:1, Full
Megapixel: 15M, 50M
Night mode
Zoom: 0.6, 1x, 3x
Not in Sony Android however.
How about getting the Sony (android) camera app to run? We have already paid for it after all.
To approach what a real camera can do,
I’d still add RAW and manual controls of exposure time and focus.
Not only for night pictures, but also for movement controlled blurs (sports/cars/waterfall/whatever)
Auto-focus and auto-exposure are features.
Manual focus and exposure are not even features, so, let’s keep them!
My camera app wishlist:
Everything else is just extra at this point 
Zoom to native screen resolution to check focus on already made photos.
It could be something like double tap to reach the native screen resolution or a [1:1] button somewhere.
It would allow to quickly decide if a photo is OK or if a new one should be made.
A bit off topic.. But…
Screenshots are not disabled per se. Normally pressing both volume up & down can be used for screenshotting but in Camera app volume keys can be used for photo capturing. We have introduced also screenshot Top Menu toggle which hovers on the screen. You can screenshot with that as well. When the screenshot button is used, it hides itself from the screenshot.
Awesome. I enables to take screenshots of the photo application and it’s instantaneous.
Screenshots from key-combination are pain for all the users I know, especially the less tech savy ones (like my mother).
This explicit screenshot feature is clearly something I noted as being better in Sailfish OS than the average Android experience.
Bravo for this.
Like said, off topic but something that might help. Surely, not Camera app related.
Personally, I’d like a way to quickly choose the photo resolution. I often take pictures just for taking notes/sharing info and given the big native res of the jolla phone, wouldn’t like to have send such big pictures over email.
i would like to add: Portrait Mode (Sharp Focus on motiv, blurred background)
What about working filters again…?
What about taking a bit inspiration from the Advanced Camera (cc @piggz) and merging something from there? 
If we get several modes it would be nice if those photos from special modes would be stored in an explicit (sub)folder:
Home
Or at least with an indicator:
20260113_160527-pano.jpg
I prefer the indicator in the filename. it’s a much more orderly solution.
In addition that would also need some features for the gallery app too, but discussing that here would be off-topic.
For 12 years now I miss the zoom gesture of the Nokia 808 pureview. It was brillant because you could handle the zoom one handed, just by
sliding up (zoom in) or down (zoom out) with one finger anywhere on the screen.
ref. at 5:50 here https://www.youtube.com/watch?v=fJVy0oMZ86o
So one handed videos with multiple zoom in & out, holding the phone above the heads of a crowd at a concert was an easy task.
And you could choose the zoom factor to your wish before releasing the finger to apply it. In that matter it is even more intuive than the volume keys (pls keep them as zoom adjuster anyway). For pinch zoom you always need two hands to operate (one hand to hold the phone & one to pinch zoom).
Try it with an old 808 and see, how nice the zoom is to operate.
I like to have that you can take slow motion video (120 frms/s ) also whit front facing camera
