That's because you guys are holding the wrong idea. while you guys might want instant result, the fact is these are not made for that. What you guys need are Polaroid
And on in camera JPEG B&W, one cannot just expect the camera to do anything else except giving you the such as these are really a reflection of actual scene. Just as people keep preferring more saturated vivid color. B&W photographer seems always intend on pushing the tonal range to unrealistic extreme.
Even in film, such result are to be expected as there really is not such extreme in most case in real life and most scene in B&W are just well plain gray and flat.
If you guys even shoot film and do darkroom ( densitometry ) mand shoot digital B&W using a grey scale ( test wedge ) you guys would understand that what these camera does is just faithfully reproducing the tonal range. Now whether that is what you guys like or not is another matter. One reason why even in camera need various tone curve setting
And further to that on a Nikon or Canon of todays, one really should load their own setting into the Camera via the Picture Control or Picture Style
