Is multishot possible for the Q2 with a future firmware upgrade?

I am sure the answer is simple but I am not sure whether there has to be a hardware thing waiting to be activated by firmware update or whether it is 100% a firmware thing. Just asking:)

The simple answer is: no.  The Q2 has no moving sensor, you need that for multishot. Image stabilization in the Q2 is done via optical image stabilization in the lens.

ΟΚ, Ι guess that settles that:)

In theory, it would be possible without moving the sensor, as it is likely done in Pentax and Olympus cameras (hand-held high-resolution mode). Instead of shifting the sensor, the camera uses slight shifts in camera position (hand-held). I doubt it would be added in Q2.

You can also do it in the post: https://www.dpreview.com/articles/0727694641/here-s-how-to-pixel-shift-with-any-camera

Technically it has to be possible: it has to be the same to move the CMOS a few microns in two directions 
as the movement of a few millimeters (per meter of distance to the subject) in two directions of the subject and environment, 
and to develop the software for the treatment of the images...

I think moving the camera is not a good idea, as it changes the point of view...

I thought we are talking about using the highres mode for high quality shots. This requires a tripod and with a tripod the only thing that can move is the sensor. The other options are hit or miss.

I worked on a multi-shot application back in the 1990s.  The idea was to get increased resolution when scanning in business cards held in your hand and captured with the bezel camera of your laptop (yes there were laptops with cameras back that far into the dawn of imaging). You just save enough images to get some spread and then average them, or combine them in some more clever way.  It's called super-resolution and is a very old idea.  As with multi-shot sub-pixel resolution, it never worked as well as we had hoped, but it works.

I suspect that every time you capture a bar code or QR code with your phone you are using some similar averaging algorithm to separate the signal from surrounding noise.

Hey,

you can do it manually [ 😉 ] 

 

 

 

If you would like to make the effort. 

And if someone writes a script for photoshop then it´s even easier. 

You could get 150 to 200 mpx.

But you only need it if your work is presented like this:

Or if you plan a mpx website.

With LR’s recent updates its also possible to just use Enhance and Super Resolution option without all the other fiddling to get an equivalent higher pixel image.  I haven’t tested this method with the Q2 but I have compared it with Multi-shot in the SL2-S and see no significant difference in image quality.  I think the LR algorithm is equal to or perhaps even slightly better than the in-camera Multi-shot in some scenes.
 

Unfortunately, LR doesn’t support the Q2Mono sensor for the Enhance function.  The Super Resolution option is supported but I found the results undesirable with horrible areas of pixelation.

I tried it once on my MacBook Pro (retina, older model) and it took an eternity and a half... Never tried it again:/

I’m on a new MacBook M1 so it only takes 7 seconds to process.

Thanks for sharing.

I gutes Dung this manually is just if you really want or need to get a higher resolution. 

It would be great if we could get pixel shifting (no matter how they do it) in the q2. 

I just don't see the point why not.
