An interesting option with modern mirrorless system cameras is that very many lenses can be attached to the cameras. Either with a suitable adapter or, if the manufacturer offers it, directly via a suitable bayonet mount. Even if no lens data is transferred and you can only work at working aperture, this works well.

A few months ago I bought a fisheye with a Fujifilm GFX bayonet. The TTArtisan 2.8/ 11 mm is quite cheap and only works in manual mode, autofocus is not supported and it also does not fully draw the image circle of the large GFX sensor. However, it has a surprisingly good imaging performance and in post-processing it is possible to correct the strong distortion that is typical for such a lens. Then you can use it like an extreme super wide-angle lens. What you have to bear in mind is that the correction costs quite a bit of resolution. On the Fujifilm GFX100s with its high resolution of 100 megapixels, you still get a very good image quality.

I went out with the lens very early in the morning. The following two pictures were taken at the 'Campus Handwerk' and Bielefeld main station.
