What if Nikon made cars? We wouldn't have a speedometer!

You control the engine speed with the accelerator pedal, and the speed is determined by the gear ratio and wheel diameter. Photography works the same way: you change the aperture, and the depth of field (DOF) is determined by distance and focal length. When driving, however, the task is usually not "Drive at 3000 rpm," but "Drive at 50 km/h." Although the speed can be derived from the engine speed using tables, car manufacturers have given us speedometers. When taking photos, I rarely feel the desire to shoot at f/5.6 or f/13; rather, I aim to achieve a specific depth of field. For a portrait, 3-5 cm, for a couple perhaps 25 cm, for a Beetle 8 mm, and for a car 2.5 m. Although every modern camera has many times the computing power of the first lunar landing computer, we've remained stuck with the f-number introduced in 1900.

Before switching everything from aperture priority to depth of field (DOF) priority, there's an intermediate step that wouldn't restrict anyone's usual workflow. You could simply display the DOF in the format -12/+30cm of the focus distance. This display would then need to be shown not only in manual focus (MF) mode, but also optionally in autofocus (AF) mode.

To those who see every suggestion for improvement as an attack on their favorite manufacturer, I'd like to ask how they work to achieve a specific DOF. Do they focus, then move the camera away from their eye, read the distance and focal length from the lens, enter both into an app, and then set the calculated aperture on the camera? You could do it that way, but considering that DOF changes exponentially with distance, it's rather cumbersome.

I use the Z8 intensively and am genuinely impressed overall. But the deeper you go, the more you notice: this camera has all the data and processing power to act intelligently – yet in a surprising number of situations, it simply doesn't. Here is my list. I'm curious whether others see it the same way or whether I'm missing something.

AF mode missing from "Recall shooting functions" This feature is brilliant – but the AF mode (AF-S / AF-C / MF) is absent. Whoever made that a deliberate decision: I don't understand it.

"Recall shooting functions" is identical on all buttons The feature can be assigned to multiple buttons – but the configuration is the same on all of them. So there is effectively only one retrievable settings set, just accessible from different positions on the body. What is the point of multiple Fn buttons if they all do the same thing?

These two points together create a neat follow-on problem: Pin-Point only works with AF-S. If the feature were configurable per button and included the AF mode, one button could simply be assigned: Pin-Point + AF-S. One press – done. Instead: two manual steps, for a combination the camera itself knows about.

AF-On is unused in MF mode In MF mode, AF-Lock makes no sense. Why isn't the button automatically reassigned to AF-On?

Back-button AF: why two settings? When I assign AF-On to a separate button, I expect the camera to automatically decouple AF from the shutter release. Instead I have to do this explicitly in a second setting.

"Maximum aperture LV" – and who protects the sensor? Nikon's own documentation warns: with the function active, do not point the camera at strong light sources or damage to internal electronics may result. Responsibility lies with the user. The camera measures the light situation in real time – it could protect itself without any difficulty. Instead: you activated the function, you bear the consequences. For a product in this price category, that is simply not good enough.

VR on a tripod: why do I have to decide this myself? The camera knows shutter speed and gyro sensor data. It has all the information needed for intelligent automatic VR control – and doesn't use it.

Auto ISO and reproduction ratio The reciprocal rule is a blunt instrument. In macro or portrait shooting, subject movement is the critical factor – not focal length. The camera recognizes faces and knows the reproduction ratio. Why doesn't this feed into the calculation?

Where is the DOF display? Focal length, aperture, focus distance – all known. A real-time depth of field display would be trivial to implement. Why doesn't it exist?

Rethinking bracketing for RAW photographers WB bracketing: irrelevant for RAW. Exposure bracketing: usually only changes ISO. What would actually help: aperture bracketing and handheld AF bracketing as offered by Fujifilm. Nikon's focus shift is usable on a tripod – and little else.

All of these are purely firmware and UX issues. No new hardware required. What do you think – am I missing something, or do you share these criticisms? And has anyone had any experience getting this kind of feedback through to Nikon?
