I read some reviews of the 90D and Fv mode. Old is new again.

Up until some boredom set in this morning, I've been satisfied with the 80D as my only digital camera. I went to TDP to read Bryan's review of the 90D, just to see if it offers any features I could use. The new Fv mode sounded interesting, so I investigated more reviews and user reviews. Fv seems extremely flexible, with its biggest selling point being very quick changes from Av -> Tv -> M -> P -> Av. Keep in mind here that I shoot about 95% in Av, and the rest in Manual. No other modes needed, thank you. After thoroughly investigating Fv, its purpose, possibilities, and implementation, I deem it very interesting. It is certainly worth at try. Kudos to Canon for the innovation of Fv mode. I am sure most folks who give it a serious try will end up using it almost exclusively.

Then I realized this is exactly how my Pentax 645N works. It was released in 1998. Except the implementation is even cleaner on the 645N. It has no 'modes' at all. M, Av, Tv, P are all available and instantly switching from one to the other is as simple as changing the desired setting. Want auto aperture, set 'A' on the aperture ring. Want auto shutter, set A on the shutter dial. It is wonderfully easy to use, without ever bothering to read the manual. Intuitive, simple, powerful.

You just have to appreciate Canon finally getting 20+ year old ideas into their cameras! Really, I do love my 80D. Pretty sure I don't need a 90D, though.

I shoot M mode with a fully configured auto ISO with EC, and after trying FV, decided that the way I use M fits me better.

The 5DIV has Fv?

Anyway, the way I use a digital camera, Av and M are quite sufficient. Even more so since Canon allows configurable auto-ISO and EC in manual mode. If I had a 90D, I'd likely spend time with Fv, get proficient with it, and never change my mode setting again. Which is pretty much what I do with Av on the 80D.

I don't need or want a 90D at this point. I just found myself reading some reviews because I've got about $900 in my camera slush fund from selling off my Pentax short primes in favor of the excellent 45-85mm autofocus zoom. Which is gobble-d-gook for, "I'll probably buy a 90D next month."

What I'd like to see is a 'mode' where you manually select everything (as in M) but which maintains exposure if you suddenly need to change the shutter speed or aperture. So you suddenly need a quarter of the shutter speed to freeze some motion, or 2 stops more DOF, so the camera automatically ups the ISO by 2 stops to maintain the exposure value you've manually set. This would be different to auto-ISO because you're not using the meter, just your manual settings for exposure. They could call it Ev. Mind you, a proper ETTRv, like Tom R's been railing for, would be better still.

I can see the usefulness of such a feature. For the most part, it is already available. In either Av, or Tv mode (80D), I can set *H (Exposure lock & hold) with the * button (programmed that way) and in Av mode I can freely adjust the the aperture and the camera will maintain constant exposure, ditto Tv mode and shutter speed. If you set auto-ISO, the camera will float ISO within your preset parameters, too. *H stays in effect until you press the * button again. Admittedly, a setting where M worked that way would be helpful, too.

The EOS R has Fv mode.

I need to give Fv mode a try on my new EOS R. I shoot mostly in Av mode, with occasional Tv or manual depending on what I'm shooting. I really like the idea of Fv, but am so ingrained in my shooting habits that it's difficult to switch. I am going to force myself to experiment during our next trip.

I use an 80D and was unaware of the *H setting so thanks for that, it may be useful at some stage (though I'm usually in M). I tried *H in M but sadly it didn't work as I'd described.

In M, I usually know the lowest shutter I need, so I set that, it becomes my secondary priority. I will move AV around as needed most often. I set up auto ISO with EC slanted to about +1/3 so that it can float ISO in 1/3 stops and push exposure just a bit to the right, coupled to my metering mode, and that seems to keep a constant exposure.

I tried Fv for a while, but having shot M with auto ISO with exposure compensation so long, it just fits about everything I do. It is my mode for about 95% of everything I shoot.

I just tried *H in Manual mode, too. I'm not sure what it is supposed to do, but the way it actually does work is kind of stupid. *H means EXPOSURE LOCK & HOLD. It appears not to work at all in Manual. If that is the case, why is it selectable at all?

Here is the skinny on FV mode. Personally I would never use it. Its another auto mode where the camera recognizes the lens you have on and sets aperture and shutter accordingly

Once you become proficient with a camera aperture and shutter speed are what you are concerned about....especially with features like auto ISO and safety shift that keeps aperture and shutter speeds where you need them to be for the subjects you are shooting

Read here for FV mode. I was curious as well. Not something I would use

I use an Eos R and I can't see why I'd ever use M again, now that Fv is available.

Fv can be configured just like M but allows you to select AUTO anything if you feel the desire. It just makes M more flexible.

If they simply allowed you to select AUTO for each variable in Manual and provided 4 dials, so you could control each variable independently, there'd be no need for Fv.

As it is, it compensates for the lack of dials whilst providing even more flexibility than M.

Too button and menu intensive for me, so until they do some sort of dial setting for those, I won't even play. I have already reset about all buttons to things that are important to me and I want to go into a menu driven system as little as possible, even the Q screen itself. I think this will evolve over time as Canon tries to figure this out a bit more.

Maybe 3 touchbars... one for aperture, one for shutter, and one for ISO...

Buttons on the left = auto, slider changes the values, button on the right programmable to whatever.

Both of you address my point exactly. Canon is figuring out how to make this work, properly. Pentax did it on the 645N more than 20 years ago. No modes to select, no extra buttons to push, nothing.

Shooting in AUTO (P) and suddenly want to lock in your shutter speed? Simply select a shutter speed.
Shooting in Tv and need a specific aperture? Set shutter to A(uto) and select your aperture. Set shutter to A(uto).
Shooting in Av and need full manual control? Select a shutter speed.
Shooting in Tv and need full manual control? Select an aperture.
Shooting in any mode and need AUTO (P)? Set shutter and aperture to A(uto).

Pentax did it 20 years ago. Canon will get there. Have faith.

I am not familiar with Fv mode, except for what I have read (very liimited) in the first 13 posts of this thread...but on first blush it seems to me that
an amateur with 55-250mm lens (and especially with one of the 10:1 zooms on the market) mounted on the Fv set body are automatically 'protected' by the automation from the camera selecting 1/60 f/8 ISO 1600 although the lens has been zoomed from 55mm (where 1/60 is 'safe' to use) up to 250mm (where 1/60 is decidedly unsafe to hand hold)

Am I wrong about this first impression (...while I go to read the user manual for the EOS R to learn more)

Perhaps the somewhat clunky interface found in the EOS R is intentional by Canon, so that shooters like yourself will be pulled up to buy the 'pro R'...
just like Rebel and nnD is now, vs. 7DII/5Dn/1Ds.
