I don't know if you can do this with the 550D, but with your 7D2 have you considered Manual mode with Auto ISO?

I use this method with my 1DX and 7D2 as it means that I can change settings very quickly without taking my eye from the viewfinder and (more importantly) without using my brain! If you go into Custom Functions, and assign EC (Exposure Compensation) to the "SET" button you can adjust exposure VERY quickly - handy for BIF and Airshows.

Using this setup my shutter speed is under my right index finger, my aperture under my thumb. So I just set the parameters I want and can instantly see if the ISO is within reasonable limits. With EC on the SET button any compensation can be set in well under a second without losing sight of your subject too.

It may sound a little daunting - but it is not, these days using my point and shoot is a MUCH more difficult challenge!

Unlike the 7D Mark II, the 550D (T2i) does not have the EC feature when you use Auto ISO in Manual mode.

I can't speak to P because I don't use it.

In Av mode, you select the aperture, the camera will select the SLOWEST shutter speed it can (according to your parameters, if user select-able, and then give you the ISO to allow proper exposure. If sufficient light is available, the camera will give higher shutter speeds, while keeping ISO at 100.

Putting the camera in P or Av, and selecting auto-ISO is basically telling the camera, "I don't care what the shutter speed and/or ISO are. Just take the photo." If you do care what the shutter speed and/or ISO are, there are settings for that.

Some cameras allow setting minimum and maximum values for all three exposure parameters. It surprises me that the upscale 7D2 does not.

I believe the 7dii allows you to enter a parameter for min shutter speed with auto ISO. Either absolute or I think 2x FL. But, in Av mode, as mentioned above, you aren't supposed to care about shutter speed. If light starved Tv will likely maximize aperture and then start cranking iso, just set your tolerable shutter there.

One more TIP regarding reading the manual dialog.....
One way to rapidly learn any new camera (or piece of software) is to explore every menu, every option to see what's there. Then look up in manual for anything you don't understand.

Exactly what I mean! An upscale camera like the 7DII should have functions that were available 10 years ago. Why doesn't it? I could restrict any exposure parameter to any values I selected, and it applied to ALL shooting modes, on my 1DIII/IV. Ten year old cameras.

What I miss most about my 1DIV is the customizability. The 80D is its equal wrt AF, but doesn't touch it in Custom Functions. Of course, video/LV on the 1DIII/IV were cumbersome, at best.

On the 7D2, you can set minimum shutter speeds and minimum ISO values, while using auto-ISO in Av or P modes. See pp. 154-159 in the user manual. Isn't that what you want?

Wait, I am saying it does have it, aren't you finding what you want in these manual pages?

:oops::oops: Well, this is more proof that my memory is failing. Apologies to you, and to the 7DII. Your response made me go back to the manual. I found these features o pp. 438-9. Another feature I liked (1D4) was the adjustable frame rates for both high- and low-speed bursts. The 7D2 has that too.

I thought I made a thorough comparison of the 80D and 7D2 before buying the 80D. If I did, I am certainly remembering things wrong. :oops::oops:

It may not be the issue of failing memory, but more an issue of increased complexity!
I just put a new printer with wireless printing capability into use, and it came with a two-sided Getting Started guide. While it has an on-line manual, while setting it up I was not aware of that feature, so i downloaded a PDF from the web 900+ pages of user guide?!

180 pages for the 5D(c), 548 pages for the 7DII...3 times as much information to cope with. Even the 1Dx has 'only' 430 pages.

Thanks for the vote of support, Wilt. And for trying to bail me out of my own dumb-idity. I appreciate it. But don't think for a minute that POTN is the ONLY place I do/say stupid $#!T. :).

Just this morning I got the PNB out so my wife could make my muffin (no jokes, please). Not 10 seconds later, I saw the PNB jar on the counter and put it away. She hadn't touched it yet. I am truly a scatter-brain.

I assume that PNB stands for peanut butter and not something like a Petrified Ninety-year-old Butt. :p

Well it certainly ain't Perky Nineteen year-old Boo... wait, this is a family forum. Yes, peanut butter. Crunchy, if you must know.

Pity as I find it to be a great feature.


Life is for living, cameras are to capture it (one day I will learn how!).

I'm a smooth peanut butter man myself. While I'll admit crunchy peanut butter is sharper both in the center and edge of the bread, I find smooth peanut butter gives you less noise, especially in lower light, with much better bokeh. We each need to use the peanut butter that gives us the sandwich results we had in our mind's eye.

Now that we've gone down Weird Road, is it safe for me to admit I also like creamy PNB sandwiches: PNB, butter, and cheddar cheese on white.

I was trying to find a way to get this back on track, but there is no way I am rubbing PB on my 7D2 to do it, so I gave up. :D

Ok, I'll try. I find the 7D2 much more attractive now that I have its Custom Functions in my head. Damn! I bought the 80D 8 months ago. Surely I don't need an 80D and a 7D2, do I?
