It is not a general-purpose lens, it has "character" and not only because of manual focus. When fully open, it is quite soft (good if that's what you want) and of course, the depth of field is minimal (also good but it means it requires a lot of attention to focus), from f2 something and onwards it changes character and becomes sharper and clearer (also good if that's what you want!).
I would prefer it to have a click on the aperture adjustment ring. Also, it has no electronic communication with the body, so the camera does not know the focal distance to adjust the image stabilization (so you have to declare it manually) and of course, there is no f number recorded in the photos' EXIF.
But, at this price and with f0.95, these are suspicions...

My comment on this lens is premature, but it seems fine to me. I am only making this comment to point out some things that will save some people time and prevent them from having the wrong impression of poor image quality:

If you have a camera with IBIS, especially Olympus (I don't know about Panasonic or other cameras with IBIS), this will not work correctly unless you manually set the focal length of the lens in the camera.

For the Olympus OM-D M10 IV, you can do this as follows:
- Press the shortcut menu button (top left, next to ON/OFF).
- Click on the bottom left part of the menu that appears on the screen, where it says M-IS1.
- Press INFO to declare the focal length of your lens.
- Use the < and > buttons on the selector to choose the position of the digit you want to change, and use the up/down buttons to change the number.

Regarding focus magnification, if you set the camera to use focus magnification from the menu, it will not work with manual lenses (unlike focus peaking, which works normally). However, if you assign a button to activate focus magnification, it will work with manual lenses. So, you can assign, for example, the video capture button or the AEL/AFL button as the focus peaking button, and another button as the focus magnification button. This combination will give you maximum accuracy in focusing.

Attention here: before assigning the digital teleconverter button as the magnifier, make sure it has not been pressed once before and left in teleconverter mode. Otherwise, it will function as both a magnifier and a teleconverter, and you will not notice it from the JPEGs (because the resolution will be the same due to upscaling), but only from the RAW files, where you will see the actual frame.

Another thing I liked is the cap of the front element of the lens. This cap does not tighten with the usual mechanism found in almost all other lens caps, which comes into contact with the UV filter, but it simply snaps on perfectly with a push. As a result, there is no chance of scratching the UV filter that you will attach to your lens! No more dilemmas of "cap or filter or both together" if you are one of those compulsive people who deal with such details :-)

Happy shooting!
