I promised some more pictures using the 24-200mm F4-F6.3. Since it is not a fast lens, I had to rely on higher ISO numbers. Using a full frame camera like the Z5, that isn't an issue at all. The image above is sharp enough. You can almost read the yellow digits on the signs at the train stop, but not quite. I think, the lens blurs the pointy lights a bit more than the 50mm F1.8 at F8.0 would do, but I am not sure. The image is carefully edited in Lightroom to enhance the blue hour, and to remove noise without destroying details.

Does this image have to be sharp? Not really. There is also no need for more contrast. In fact, this is one of the images where I tend to decrease clarity. Bokeh is also not needed here. You could zoom in a bit more for a more abstract image. After all, you have a zoom. As long as you are aware of the effect of your focal length, use it!
|F14, 76mm, 1/125, ISO100|
Here is an image with more contrast. The lights have been reduced with the slider in Lightroom. This gives the leaves in front of the bright backlight a chance to become visible. Clearly, there are blown out highlights.
|F8, 120mm, 1/125, ISO1250|
Another F8 image. The noise reduction shows its toll only if you pixel-peep the face. I should have taken F6.3, and I'd love to have had F4 or better. For this kind of event shots, I'd use a prime if I had to deliver a professional image, or one of the costly telephoto lenses with F2.8. In fact, the 85mm F1.8 would do the trick, since I can get closer as a press photographer.
|F13, 71mm, 1/100, ISO100|
This was just a test. The scene was less dramatic. So, I enhanced the dynamics quite a bit. It is still not a good image. The sharpness of the trees is done with 90% in Lightroom.
|F6.3, 200mm, 1/200, ISO280|
You cannot really do macro with this lens. This is a full image at 200mm, at about the closest focussing distance. For a casual flower image, this is okay.
|F8, 105mm, 1/80, ISO100|
This is the sky towards the West, still bright enough to allow ISO100. The VR of the lens does allow 1/80 easily, maybe anything up to 1/25 at 100mm. The sky below is way darker. For sharp handheld shots, I'd take ISO1600 without any hesitation. The Z5 can handle that.
|F8, 170mm, 1/60, ISO1600|
Here is a last one at 25mm. I find the sharpness sufficient for my purposes. At F4, it may be a bit too blurry for some purposes. Things improve at F35mm and beyond, and/or stopping down a bit.
