Thanks - this is good, and as the comments show - some common ones are missing.

The website doesn't print well - for a reference sheet

When I first came to the Hog I had to google BIF and GAS
GAS = gear acquisition syndrome, the need to always buy more camera gear

Every field has it's own set of acromyms. Designed to make it easier for "members" to communicate and to confuse non members. The military and/or medicine are the worst offenders. Google- Glossary of digital photography terms- and you will get more info than you can digest.

You should look at the T6I/S also - saves you $$ !

It sounds as if the 80D would be ideal for you...

- It has an articulated LCD screen (7DII doesn't). It's also a "Touch Screen" (7DII's isn't).

- Both 80D and 7DII have Canon's relatively new "Dual Pixel" feature, which really speeds up focusing in Live View.

Both 80D and 7DII are excellent cameras. 7DII's AF is a little faster and better tracking movement than 80D.... but the 80D is actually quite good at this too, and would be quite an improvement over your T2i.

Both the 80D and 7DII have active matrix/transmissive LCD focus screens that reconfigure depending upon what focus mode you're using. This is different from the fixed focus screen, in your T2i, which has 9-point AF with one higher sensitivity, dual axis, "cross type" AF point at the center, while the other 8 are less sensitive single axis points. All 65 points in the 7DII and all 45 points in the 80D are dual axis/cross type. The center points on these cameras are also further enhanced... diagonal dual axis.

Your T2i has AF that's able to work at -0.5EV light levels. Both 7DII and 80D are able to focus at -3EV (approx. moonlight). So both these cameras will do better for you focusing in low light.

Your T2i is "f5.6 limited"... with a smaller lens native aperture it's unable to focus. Both 80D and 7DII are "f8-capable", meaning they can focus a lens with native aperture as small as f8... For example, an f5.6 lens combined with a 1.4X teleconverter will be able to focus on the 80D and 7DII, but won't on your T2i. The 80D has 27 "f8" autofocus points (out of it's 45 total). The 7DII has only one "f8" point, at the center (this is the case with other Canon "f8-capable" cameras, too... except for 1DX II which has all 61 AF points "f8-capable".)

So, both cameras offer big improvements in AF performance overy your current camera. The 7DII's is slightly higher performance because it uses a design similar to 1D-series Canon cameras, whre the AF is handled by a discrete chip, separate from the image processor. Other Canon, aside from 1D and 7D-series, use the same processor both for image handling and for focusing. The reason the 80D's AF is superior to your T2i's is because it uses a 2 generation new and much more powerful processor. Your camera's highest settable ISO is 12800. The 80D offers up to 25600 and the 7DII up to 51200. When it comes to high ISOs it depends a lot upon how you'll be using the images, personal opinions about noise, and techniques handling image noise. So I'll leave it to you to judge what's actually usable. I've used my two 7DII as high as ISO 16000 and 8000 with good results... In comparison, with my 5+ year old original 7D... which used similar 18MP sensor and processor as your T2i... I never went above ISO 6400 (though I know other people who used higher ISOs).

Neither camera has huge increase in resolution compared to your T2i's 18MP. The 7DII is 20MP and the 80D is 24MP. But they both are "five year newer technology" and will give you superior image quality. The 80D uses the latest and greatest APS-C sensor from Canon (80D's is similar or same as T6i/T6s... while 7DII's is similar to the earlier 70D's).

Both cameras give you 100% viewfinders (up from 95% on your T2i). They also both use true pentaprisms, while your Rebel series camera uses a penta-mirror. This should make for a brighter viewfinder (but there is some slight loss to the active matrix/transmissive LCD focus screen). The T2i's viewfinder has .87X magnification, the 80D's is .95X and the 7DII's 1.0X, so both will appear a little bit larger than your camera's.

80D and 7DII both have 1/8000 top shutter speed (compared to 1/4000 on T2i) and 1/250 flash sync (compared to 1/200). Not sure, but typically Rebel series shutters are rated for 75,000 actuation lifespans. 80D is rated for 100,000 and 7DII for 200,000 clicks. Your camera's top continuous shooting speed is 3.7 frames per second, 80D is over twice as fast at 7 fps and the 7DII can shoot at 10 fps. Your camera needs to slow down or pause to clear its buffer after 6 consecutive RAW shots... 80D can handle 25 and 7DII manages 31 RAW... so both have much larger buffers. The shutter lag of your camera is 90 milliseconds. On 80D it's 60ms and on 7DII it's 55ms.

Compared to T2i, the 80D uses a more advanced semi-pro or "pro-sumer" design, with more direct access to various controls and better info display. The 7DII takes this even farther to be a little faster handling and make it more possible to adjust settings while keeping the camera to your eye, but the 7DII has less automated support for inexperienced users. It's more fully pro designed, with the most experienced users in mind. The 7DII, in particular, is highly sealed for dust and moisture resistance and uses a mostly magnesium exterior body shell. The 80D uses more high impact plastic and less sealing to keep cost and weight down, but still should be a step up from T2i.

Both 80D and 7DII use larger LP-E6N batteries, which give about twice the number of shots per charge as the LP-E8 in your camera. Both cameras have built in GPS, which your camera lacks (but which drains batteries faster). The 80D also has built in WiFi, which can be useful to control the camera remotely with a smart phone, for example (up to about 30 feet range). The 7DII doesn't have built in WiFi... but Canon is introducing a relatively inexpensive ($40) WiFi transmitter for it. They also offer a WFT-E7A Version 2 wireless file transfer module for 7DII that can work up to 400 feet and is able to download images automatically... but costs a whole lot more (about $650, if memory serves). T2i doesn't have WiFi, but there are third party devices that can be used with it for similar purposes.

There's lots more!

If you photograph a lot of moving subjects, the 7DII would be the best choice (BIF = "Birds In Flight", one of the most challenging types of moving subjects).

However, the 80D really is no slouch and for all around shooting purposes should serve you well, and it sounds as if it would best meets your expectations.

And, yes, the T6i or T6s might be worth consideration. They offer much of what the 80D does, though with a slightly scaled down active matrix, 19-point AF system that's not as usable in low light or "f8-capable". The T6i is most similar in design and controls to your camera. The T6s is something new for Rebel series, uses controls that are more similar to 60D/70D/80D. Either of these cameras would use penta-mirrors instead of pentaprisms, would not have as fast shutter speed, flash sync, or frame rate, won't have as large an image buffer, and lack some features such as Micro Focus Adjust. They do have articulated LCD screens and faster Dual Pixel focus in Live View. And either would be a very nice step up from your current camera... just not quite as nice as 80D!

Incidentally, your flash and accessories all should work fine (I have three 550EX that work just fine with my 7DII's). You didn't mention what lenses you have, but along with the 80D Canon introduced a new EF-S 18-135mm IS USM lens. This is the first USM lens that's been optimized for videography. While USM are generally fast and accurate for action shooting, most are too noisy and not smooth enough for video work. Canon STM lenses are preferable and recommended for video. (Both are faster, quieter, more accurate than a third type of focus drive: micro motor. That's used in a lot of more entry level lenses... in Canon's case lenses that aren't marked either STM or USM are micro motor.) The new 18-135mm IS USM is the best of both worlds. First lens of this type, it's designed to be quiet and smooth... great for video. It's also at least 2X faster focusing than the same lens with STM drive... so can better handle challenging action shooting. And, anyone shooting video might also be interested in an accessory power zoom module Canon is offering for use with this lens (exclusively, at least for now). You are probably aware, there are lots of other excellent lenses available.

Have fun shopping!

Wow, that's a very good analysis...
I'll simply say that if you are interested in video at all the 80D will be your better choice than the 7D II.

If you shoot birds or sports, go for the 7D MkII; if you shoot everything but that, get the 80D.

I am slightly confused about USM vs STM. In one sentence you indicate USM is better for video, in another you say it is too noisy for video.

That would be found in the GOPT

Rockwell's review - http://www.kenrockwell.com/canon/t6i.htm

Jerrin1 Loc: Wolverhampton, England

I used to have a 7D mark 11 and I reckon it is a brilliant camera. At the same time I had a 70D. As far as I am aware, the 80D is the successor to the 70D but the 7D mark 11 is still above it in the Canon hierarchy. If I wanted a camera for stills I would choose the 7D mark 11 over the 80D every time. If you wish to do a fair amount of videography then the 80D is a better choice. The 7D mark 11 is really aimed at the nature/sports enthusiast and some professional photographers.

USM is better for pictures; STM is better for video. The STM has a quiet motor, the USM is a little too noisy for video because while it's autofocusing the motor noise can be picked up by the microphone in the camera. But the USM motor is considered more robust, smooth, and faster at focusing.

This ^^^^^^^!!!
Many video shooters use a external microphone too...
