An additional piece of information regarding the aperture setting: Bot the Viltrox lenses for DX/Z and now the Voigtländer offerings allow the user to set aperture directly on the lens through the aperture ring there. This is possible because the internal electronics communicate with the camera and inform about the actual setting. In my opinion, this feature gives the user added freedom and versatility. The downside might be that the ultimate exposure accuracy is compromised as the metering partly is conducted with the lens stopped down. I haven't noticed this as a practical issue, though, but it should be mentioned.

I have the Voigtlander 21mm Ultron f1.8 and the 35mmn Nokton f/1.2 VIII. Both lenses give great results on the Z FC. However, by far my favourite lens thus far on the Z FC is the Jupiter 3 50mm f/1.5. It really is a very special little lens with lovely DOF and it's tiny too so even with the adapter it's still a very compact setup and these lenses can still be had for a fraction of the price of a Voigtlander. I paid £170 for my example. Here's a quick shot of my lovely wife with that lens.

A touch too low-key for my taste but otherwise a lovely portrait!

Everyone's computer screen is different, Ian. I'm on a MacBook Pro with the light at max.

For your own use, you can of course use what settings you like but for sharing images with others, it is good to follow standards. There are display calibration tools available for the purpose of matching images across display devices and also between displays and paper. I use xrite i1 Display Pro. The outcome of the calibration may not give a perfect match but it will reduce differences considerably. The target calibration standard can be set in the software (how bright and what color temperature to set to) and the graphic arts industry and television use different standard so there is a bit of a twist there if doing both photos and video.

As it is, your image looks like a dark shadow on devices that are close to the industry standard. Even without a calibration device, you can adjust the screen closer to what is considered standard (using a grayscale bar).

It is usually beneficial (to the viewers) to cinvert the image to sRGB -- this is like the lowest common denominator for monitors.

Not the space to use for prepress work, of course, but presenting small images on web pages is an entrely different business.

As to the perceived brightness, have a look at the intensity histogram. If there is some information above say RGB 240-245, these areas on the monitor should more or less pure white (or bright red, green, or blue; depending on the actual channel values). If they don't, your monitor is set too dark. RGB 245 should look different to RGB 255, if not, the monitor is too bright. On the other end of the scale, RGB 10+ should be visibly different and don't merge into featureless blacks. If not, your monitor is not bright enough. Then there is the old struggle of gamma wars between Macs and PCs which tend to be less important nowadays, but still using a very low or high gamma leads to viewing troubles for most users. Around 2.2 should be ideal.

The best is of course doing a hardware colour calibration with a dedicated device, no matter what colour space you end up with.
