good point. if your lens are S's then they won't fit on a full frame body. alway buy non S's lens they will fit on either

Buy the Canon camera body that is in your budget. How much do you have? You got $3500 buy the 5D Mark IV. You have $1300 buy the 7D Mark II . . . and so on.

You seem happy with what you are getting from the 5D, so an upgrade in the APS-C area might be a good idea. I like the 80D. It has f8 AF and it has an awesome touch screen, especially with video, if you decide you want to start playing with video.

Given your lenses and subjects, there is no reason to stay with APS-C. It's probably more budget dependent. So you might consider a 6D or 80D, especially a refurb if money is a constraint. However, if you are considering upgrading your main workhorse that becomes a different discussion.

Seeing how you did all that with a 5 mkl, if you wanna have minimal investment just get the 5ll. It’s a huge improvement on the 5mkl.
Another not so huge step is the 5lll which has the newer style focus system and can handle action shooting pretty well, something the 5ll struggles with but you already did that with less camera.
You have given no indication if you want to spend as much as the 5lV or 5s, both very sophisticated cameras with the lV being the most advanced and versatile of all being quite able to do sports and wildlife and with high pixel sharpness!
Each model brings more to the table with more cost!!! Good luck

If you have EF-S lenses, you will probably want to stick with one of the APS-C models, unless you have budget to also upgrade to all EF lenses for full frame.

Current APS-C models:

7D Mark II... 20MP, pro-quality build & sealing, 200K rated shutter, 1/8000 top shutter speed, 1/250 flash sync, ISO 100 to 16000 (expands to 25600 & 51200), 100% 1.0X viewfinder (pentaprism), much improved Dual Pixel AF in Live View (DPAF), up to 10 fps continuous shooting rate, dual processors, separate chip to support high performance 65-point autofocus, all cross type, good as low as -3EV light levels & f/8 capable at the center point only, Micro Focus Adjustment, WiFi with $40 module, built-in GPS, fixed 3" million pixel LCD screen, dual memory card slots (1 CF, 1 SD), larger LP-E6N battery (dual battery/vertical grip avail.).... $1500

80D... 24MP, mid-grade build & sealing, 100K rated shutter, 1/8000 top speed, 1/250 flash sync, ISO 100 to 16000 (expands to 25600), 100% 0.95X viewfinder (pentaprism), DPAF, up to 7 fps continuous shooting, single Digic processor, 45-point AF, all cross type, that's good to -3EV & f/8 capable at up to 27 points, Micro Focus Adjustment, built in WiFi (GPS with separate module), articulated 3" million pixel Touch Screen, single SD memory card slot, larger LP-E6N battery (dual battery/vertical grip avail.)... $1100

77D... 24MP, "Rebel" series build, 75K rated shutter???, 1/4000 top speed, 1/200 flash sync, ISO 100 to 25600 (expands to 51200), 95% 0.82X viewfinder (penta-mirror), DPAF, up to 6 fps continuous, single Digic processor, 45-point AF, all cross type, that's good to -2EV & f/8 capable at up to 27 points, built-in WiFi, articulated 3" million pixel Touch Screen, single SD memory slot, smaller LP-E17 battery (dual battery/vert grip avail.)... $800. Note: Canon named this as an xxD EOS model, but it's specs & build are clearly Rebel/xxxD-series-like and it superseded the Rebel T6s model.

T7i (800D)... 24MP, top-of-the-line Rebel-series model, 75K rated shutter???, 1/4000 top speed, 1/200 flash sync, ISO 100 to 25600 (expands to 51200), 95% 0.82X viewfinder (penta-mirror), DPAF, up to 6 fps continuous, single Digic processor, 45-point AF, all cross type, that's good to -2EV & f/8 capable at up to 27 points, built-in WiFi, articulated 3" million pixel Touch Screen, single SD memory slot, smaller LP-E17 battery (dual battery/vert grip avail.)... $750.

SL2 (200D)... 24MP, most entry-level model currently, as well as especially compact & lightweight. Very similar specifications to T7i, except slower 5 fps frame rate and simpler 9-point (all cross type) auto focus. Also, no vertical battery grip available for this model... $550

Discontinued, but still widely available:

T6s (760D)... ... 24MP, previous top-of-the-line Rebel-series (superseded by 77D), 75K rated shutter???, 1/4000 top speed, 1/200 flash sync, ISO 100 to 12800 (expands to 25600), 95% 0.82X viewfinder (penta-mirror), up to 5 fps continuous, single Digic processor, 19-point AF, all cross type good to -2EV & not f/8 capable (f/5.6 limited), slower AF in Live View (not DPAF), articulated 3" million pixel Touch Screen, built-in WiFi... $850.

T6i (750D)... ... 24MP, previous next to top-of-the-line Rebel-series (superseded by T7i)... mostly same specs as T6s/760D except slightly different controls and doesn't have the 2nd LCD display on top... $650

T5i (700D)... 18MP (same as original 7D), previous top-of-the-line Rebel (superseded by T6i)... similar to T6i except simpler 9-point AF system (all cross type, same as now in SL2) and uses an older type of small LP-E8 battery... $650

Take your pick!

Or if you already have EF lenses or are willing & able to buy them, switch to one of the current full frame models: 6D Mark II (26MP, 45-point AF, first Canon full frame model w/articulate LCD screen, $1900), 5D Mark IV (30MP, 61-point AF/all cross type, $3300), 5DS/5DS-R (50MP, max ISO 6400 expands to 50 & 12800, 61-point AF/41 cross type, "R" has cancelled anti-alias filter, $3500/$3700) or 1DX Mark II (20MP, 14/16 frames per second, ISO 100-51200 expands to 50 & 409600, $5500). Previous models that are still widely available include: 6D (20MP, 11-point AF, $1300), 5D Mark III (22MP, 61-point AF/41 cross type, $2250).

EDIT: Regarding Sharpshooters suggestion about 5D Mark II... Well, yes, the II is a good solid step up from the original 5D in many ways (21MP vs ~13MP, self-cleaning sensor, HD video capabilities). However the AF system in the Mark II is basically the same as the original and both are pretty sad by today's standards (in fact, their AF systems are similar in appearance and performance to your T3i's, which got improved in T5i, again in T6i and even further now in T7i). That old, simple AF is fine for portraits and scenic shots... But not very good for anything that's moving! The 5D Mark III got a BIG improvement with a much upgraded AF system (and only relatively minor or modest upgrades in most other respects).

Isn't the 5D full frame?

dsmeltz Loc: Philadelphia

Errr yeah. But he has two cameras the t3i and the 5D which he refers to as his "workhorse" My comment was based on his indication of satisfaction with the 5D.

PHRubin Loc: Nashville TN USA

Not a bad predicament. If you want an APS-C body to replace the T3i, I have and I recommend the 80D. The 7D II, if you need the high frame per sec speed.
If you are looking to upgrade the 5D, a later 5D is almost the best of the FF bodies. Of course, there is always the 1D series.

wegriffin8642 Loc: Houston, Tx

I agree with Galaxycat...I like my 77D. It suffices for my needs and wants.

burkphoto Loc: High Point, NC

For professional level work with a Canon, I'd suggest either the 80D, 7DII, or 5D Mark III or IV. There are good reasons to choose any of them. Based on what you listed here, I'd probably try to get a 5D Mark IV if the budget allows. My preference in APS-C is for the 80D, unless the subject matter is sports action, where the 7D II excels. The 5D III still has a lot of life, so if budget does not allow for a 5D IV, a good used 5D III is fine.

I have fond memories of the 5D. It had super-smooth color rendition and tonal gradation from its BIG sensor sites. I'd probably keep it, if I were you. It may serve a practical purpose as a spare at some point. They're not worth much in trade... maybe $150 to $200 if you're lucky.

Of course if you're willing to wait until later this year, the 7D MIII is rumored to be released either with an announcement in April, or in September.

Bob Boner

If you liked your 5D, then why not go for the 5DIV (or 5DIII which cost less now).

TMcL

If you liked the 5D, you will love the 5D4. I recently upgraded from the 5D2 to the 5D4 and can honestly say it is a great camera. If you collection of lenses includes the 24-70 and the 70-200, both produce spectacular results with the 5D4. I did however need to have my 70-200 recalibrated for use with the 5D4. I don't do much video, so can't attest to the video side of things. The camera has been around for over a year now, so they are beginning to appear in the used and refurbished marketplace, which could save you a few bucks.

Good luck.
