And now they have put back the control ring, and you can set it for aperture (or anything else or nothing). On Canon RF lenses at least. I don't know for other models.

No argument. I often refer to Program mode as setting the camera to Shutter priority and Aperture priority simultaneously. The key is that in all of the semi-auto modes (Program, Shutter Priority, Aperture Priority) the camera links the two exposure controls to the meter directly. Are you going to use the camera meter? The overwhelming majority of photographers use the camera meter and that includes those shooting in Manual.

So if you're going to be like the overwhelming majority of photographers and use that camera light meter why not do so as efficiently as possible. I look at it as: For the next X0000 photos that I take what operating method will get me to the exposure settings I want as efficiently as possible. The step of adjusting shutter and f/stop relative to the meter reading is just like manual and auto focus -- the camera is faster than we are and as you correctly note the EC adjustment makes sure we retain full control.

I keep the EC function on all of my cameras preset to a value other than zero in anticipation of what I will most likey do in an average situation for that camera. Averaged over those X0000 photos I'm arriving at my choice of shutter and f/stop just a little faster than if I tried to use the camera in Manual.

Anyone who argues nonsense like the semi-auto modes in the camera take control away from the photographer don't understand how cameras work.

Right, and one of my cameras now only offers full Manual and Aperture Priority -- I couldn't care less. What matters is only the bottom line: You are setting the exposure. The camera modes P,S,A,M all provide the user full control over shutter speed and f/stop choice. As long as you're making that choice there's no critical difference just operational differences that could frankly change with the design of the camera. For example you mention the lens aperture ring. I use both Nikon and Fuji cameras. My Fuji lenses have aperture rings and my Nikon lenses don't. Big bleepin' deal -- if I can't adapt to that as a triviality I have no business using either of them.

It's really pretty simple...

Autofocus, when used correctly, is faster and more accurate than I ever was shooting manually. I take more shots and more of them are well focused, thanks to autofocus. I shot sports and wildlife with manual focus gear for a couple decades. And I was darned good at it, too!. Even so, now using AF I am able to take shots I never could before. It's faster than I ever was and more accurate! Focus is either right or it's wrong. There's no middle ground.

I don't use the "latest and greatest" AF systems with face and eye detection. Maybe some day I will. I sort of feel that takes automation too far. I'd feel like I wasn't "doing my job" as a photographer, giving up all focusing decisions to the camera in that way. Even with these innovative new features, as good as they appear to be, I still feel selecting a single AF point and me working to keep it right where I want camera & lens to focus will produce the most "keepers"... In most situations will give me the most images where focus is nailed.

However, I'm also the first to admit that there are times single point focusing is difficult or impossible to do. There are times when subjects are moving very quickly or unpredictably, where face or eye focus could well do a better job than me. And I'd have no hesitation using it. I'd probably be more likely to use it than "zone" or "group" focus, which leaves more up to chance.

It's not the same with auto exposure. There are times and places it works very well. But there are also many times when a camera's reflective metering system is "fooled" into making incorrect exposures... Times when I can do a better job setting it all myself or when I need to intervene to tweak AE with exposure compensation.

It's the same with auto white balance.... often it works very well. But there are other situations where it doesn't. Since I mostly shoot RAW, it doesn't matter very much because I can easily change color temp and tint later in post-processing. But when I shoot JPEGs I will sometimes set a custom white balance in situations where I know auto WB won't give the results I want.

Exposure and white balance are also more open to personal preference and interpretation that can vary from shot to shot, where focus is much less so.

Even if automation were able to make a "perfect" exposure every time ... There still would be situations where I'd want a high key effect, deliberate over-exposure. Other times I may want a silhouette and need to use under-exposure. It's similar with white balance. Sometimes I might want a warmer look... other times something cooler. I usually leave those adjustments to post-processing, since I shoot RAW. But if I wanted I could tweak things in-camera.

Auto exposure is far from "prefect" though. It gets fooled A LOT.

uh? How can there be a disagreement or lack of "resolution"? When M is used with Auto ISO, it's no longer "manual". Period. Auto ISO makes M another auto exposure mode. There really isn't any room for discussion. It's auto exposure any time the camera is making some of the exposure decisions, as it does with aperture priority, shutter priority, program AND Auto ISO + M (as well as certain flash modes). It's only truly "manual" exposure when the photographer is making all the exposure decisions and settings: M without Auto ISO (also B on some cameras).

I'm not disparaging "auto" or "manual". The different orms of auto and manual exposure have their uses, depending upon circumstances. I have no idea what your "position" on this might be. I didn't know differing positions were even possible. It's simply a fact that when Auto ISO is enabled with M, it becomes another form of auto exposure.

I know there are some folks who shoot with their cameras set up that way while espousing "manual exposure" as if it were the holy grail and while swearing the only way to shoot... even though they actually aren't doing it themselves.

Pentax makes that clear by calling 'M' + auto ISO 'TAv' mode - just one of the auto modes.

I would call manual with auto ISO with exposure compensation the moral equivalent of manual, but I agree that by itself it is just another auto mode.

That's what I do. It does require understanding how ISO, aperture and shutter speed interact and what the effects of the extremes are! I would hope that except for newbies everyone on UHH can do that.

No provocation here. Although manual mode is often used, I do not "treasure" any particular mode, therefore my boundaries remain limitless. Not being snarky, but it is the best way I can answer your inquiry. Good topic.

There are some specific elements involved, and I don't want to shy away from those. But please do not interpret them as provocation.

The thoughts behind this discussion arose as I was getting ready to do the latest firmware update for my D850. It was released in April, but I somehow missed it until yesterday. It apparently provides for improved operation with certain lenses. And no...it does not add the "Eye Focus" capability that many have been anxiously awaiting.

So the question is this...and I haven't been able to find a delicate way to ask it...for those who treasure "Manual" photography, exactly what are the boundaries of thta method of operation? And for the purposes of this discussion, let's please set aside the question of whether "Auto ISO" is or is not part of "manual exposure." It's been discussed thoroughly elsewhere without resolution. I'm passionate around my position on that subject and realize that others are equally passionate around their own, different, position.

BUT...it seems that many (and I mean many everywhere, not just here) who would never consider following anything other than manual exposure management would also never consider anything other than automatic camera focus. And preferably automatic camera focus that can identify, lock in on, and focus on the eye of their subject, whether human or animal. Why is the manual choice preferred in the one case, but the automatic choice is lusted after in the other case?

Now just for full disclosure here. I proudly use autofocus essentially all the time, except for night sky photography and a few other cases where autofocus falls short. I was initially quite concerned when some of my newest cameras no longer had an autofocus assist light. (Trust me...I learned that it's OK.) Because of some vision problems relating either from glaucoma or occupational exposure to intense light (my doctor and I don't agree on which), I shamelessly depend on autofocus. And yes, I use Program exposure mode a lot of the time also. It's just too good and too convenient if I select the correct metering pattern, and I am pretty shameless about that also.

Why do we think there is such a disparity in the acceptance of automatic exposure vs. autofocus, especially since various forms of automatic exposure have been around longer than autofocus? I am really interested in the responses here, especially if we can keep the discussion civil and thoughtful.

You sound just like me and change to Auto-i, Aperture mode, Shutter mode, Manual mode, Auto-ISO or set ISO, manual focus, burst mode, etc. as necessary to get the shot. Yes, my camera is set on Program mode and single shot auto focus coming out of the bag. But it will not stay that way if I can not get the shot that way. If I shot a different style or different subjects than I now shoot, the camera might have totally different settings coming out of the bag. Your and my settings, I feel, allow us to start shooting the quickest whatever we shoot. Sometimes I am lucky to have even 5 minutes to shoot with. One can not be spending a lot of time with settings or one will lose the opportunity to even shoot the subject. Yes, with more time, one can explore other settings, perspectives, and capture more details of and about the subject in front of you. But if that "more time" never comes, what does one have? The ghost town that I took a few shots of and then had to leave, with the intent to return, is no longer there, burned to the ground by partying highschoolers. What does this have to do about settings? If I didn't use Program mode, auto focus, and shoot quickly, the number of shots and shooting angles would have been substantially less. There is no longer "more time" in this case. The idea is to shoot more, not less. One must shoot for today; nothing is guaranteed for tomorrow. Anything that gets you today's shots the way you need the shots is the correct camera settings.

To me, there are three things that control light, which is what makes an exposure. That is ISO, aperture, and shutter speed. You control that light in manual mode, you need to set all three. In the old folks days we bought film rated for the light conditions were were going to shoot in (iso), them set shutter speed and aperture to complete the exposure. If we changed light conditions, we would change the roll of him out (changing iso). With digital, we still do the same thing, but instead of changing a toll of him, we turn a knob.

Focus used to be completely manual. Now we have auto focus, which speeds up the focus process, but focus is not part of exposure. It does however make for a pleasing photo to look at, but does not control exposure, which is what we are talking about when we say we are shooting manual.

If anyone has ever shot a fully manual camera they know the boundaries of the operation, although personally I don’t consider manual cameras limiting, it’s just a different animal. Pre-vision helps a lot. If one wants to shoot faster then it’s a case of being prepared for what may come. If the light is even your pre-set and one only has to focus. One example of this is to look at the number of newspaper photographs taken with Graphic 4x5’s. Remember the slogan F8 and be there? On the other hand if one has only known Auto Exp/Auto Focus cameras then that’s another deal. I personally find Auto cameras a supreme opportunity for me to shoot a lot of frames of the same thing. (: Your not burning film and there’s no processing costs. What could be better? Of course menu systems are a drag.

Personally I do tho love fully manual Metal cameras such as Leica’s, Nikon’s and others including MF. Their wonderful pieces of metal machinery, and when I use them I have a tendency to slow down, look and enjoy what I’m doing.

Although the thread was only started yesterday it's long so I didn't read all the responses. So to just answer the OP.
I don't know if it's correct to say that I treasure manual operation. I do enjoy using a camera in full manual that is manual focus (with a reflex viewfinder and without any focusing aid like split image or microprism and also not a mirrorless or a rangefinder, although I do enjoy a camera with scale focusing), manual exposure control without a meter. I do enjoy that a lot and do that often.
I do not put a limit on automation as I think whatever automation provides me with some conveniences sometimes I would use it. I don't use the following features only because I find them less convenient than not. They are Scenes mode, Green Full Auto, Exposure compensation, Exposure lock, Auto bracketing, P and S modes, Auto ISO with manual (I do use auto ISO in A mode).

The only auto feature I use is Auto focus, used for casual photos and moving subjects, the reason being I cannot focus fast enough.
Everything else I shoot manual:The reason is that how I learned!! I found that trying to understand all of the Auto mumbo-jumbo to confusing and not worth learning.
I found its better for ME and its all about ME, well for the most part.
