Your Canon T7i and 77D should EASILY be able to make fine images at ISO 3200... maybe even higher.

Below left is a test image I shot with one of my 7D Mark IIs... at ISO 16000. On the right is an enlarged detail from that image.



Yes, there is noise in the image. But it is pretty well controlled.

This image was shot RAW and went through standard Lightroom conversion to make the JPEG that's shown. No extra noise reduction in the quick post-processing (and none in the camera, since it was shot RAW).

The only tweak done to the image was a boost in contrast to bring back the blacks (high ISOs also reduce dynamic range, but it's easily corrected). That took about 30 seconds and, if anything, would have made noise more apparent.

7D Mark II are a generation older than your cameras... older sensor and processor.

My point is simply that you are probably being overly cautious limiting to no higher than ISO 800.

I would encourage you to run an ISO test series with one of your cameras (T7i and 77D should be identical... they are the same camera, except for the control layout). Use your standard workflow and at least give the higher ISOs a try. I've been pushing Canon DSLRs to ISO 1600 at least since 2006 when I was using 30Ds. I've sold hundreds of images shot at 1600, 3200. I have even shot some events at 6400 and 12800 when it was necessary (had to do some noise reduction, but I have a Photoshop plug-in for that).

Interesting that you only picked up on my observation that you seem to look at things from a very narrow and theoretical point of view and totally ignored why I find it limited from a practical standpoint.

I have photoshop elements and have no intention of post processing a lot at this time, as i have other hobbies where i dont have the 2 trolls to deal with,
user id and .joeyboy3..You were helpful. Canon suggested 800. I shoot mostly outside. I bought the 77D because it had the newer processor, logic 7?
I'll try and go up but I was limiting after speaking to Canon to 800.
My astrophotography I go much much higher.
Thanks for the encouragement. The same 2 trolls disrupt all the threads for no reason.

Your personal observations amount to nothing more than an insult.

jcboy3

Again with the insults. You can't stick to your subject, and that's what's disrupting this thread.

Photoshop Elements is an excellent post-processing program. It's more than enough for many peoples' uses.

Sorry to rain on your parade, but for all practical purposes the 77D and T7i are identical inside. They both use the Digic 7 processor, same sensor, same AF system, yada, yada, yada. With one small exception, they have the exact same specs... shutter speed range, ISO range, flash sync, etc., etc., etc. In fact, they were even announced the same day: February 15, 2017.

The exception... There is one feature the 77D has that the T7i doesn't. That's its built-in Intervalometer that can be used for time lapse or a programmed bulb exposure.

The biggest difference, I'm sure you're aware, are the display and control layouts. The T7i uses a control layout common to the Rebel series, while the 77D uses a control layout brought over from the 70D and 80D... LCD display on the top shoulder, mode dial moved to the left, AF On button, dial on the back instead of a multi-directional controller and a few other differences.

Why do I know this stuff even though I don't use either camera? Well, there were a lot of questions about what the rather oddly number EOS 77D was, when it was first announced. Turns out that where the T7i superseded the Rebel T6i, the 77D superseded the Rebel T6s. Those prior cameras were the first time that Canon had split the top of the Rebel line that way. Previously there were just T5i, T4i, etc. The T6s was sort of a "super" top-of-the-line Rebel, alongside the more standard top-of-the-line T6i. The 77D and T7i continued that, just with a change to the model naming methodology.

The T6i and T6s also were announced on the same day in February 2015. In other parts of the world, the T6i was known as an EOS 750D (Kiss X8i in Japan) and the T6s was an EOS 760D (Kiss 8000D in Japan).

The T7i is an EOS 800D (Kiss X9i in Japan), while the 77D appears to use the same name in all markets except Japan, where it's a 9000D.

The point though, is that you can pretty much rest assured that 77D and T7i set up exactly the same way would render results indistinguishable from each other.

I bought the 77D for a retirement present for myself.
From film days I always had 2 Simular cameras and one Dat on craigs list the T7i came up for sale at a great price, $450. The college kid bought it on advice from his photographer dad. And it wasn't for him. He wanted a camera for kayaking, camping, hiking, so he was going to get Olympus TG 5 or 6?.
Great deal for me. I also had a xsi rebel and T3i so I knew camera line.
I was under the impression with the camera line the ones with the "i" left out were a watered down line.
I looked at other Canon line camers but the 77D gad a new processor processor 7 where the lower end pro cameras were still the 6 processor.
I recommend the rebel line to friends and family if they want a camera in that price range

Nothing wrong with the Rebel line... Buy decent glass from the git go and some of these rebels just keep on yelling ! T3i with OLD school NON USM 100 mm 2.8 macro.. Not a PRO shot but decent with OLDER equipment.

Excellent shot.
Actually the first EF 100mm macro optically is supposed to be as good as the EF 100mm L IS macro.
Only difference is the IS.
And yes, old Rebels or even a D30 which is much older with the same EF are very good performers.

I often recommend one or another of the Rebel line, too. They're great cameras and ideal for many peoples' uses.

I started my "digital Canon journey" with a 10D way back in 2004 (transitioning from using Canon EOS-3 and Elan 7 film cameras, alongside an Olympus digital P&S that made 1.5MP images). That was a very nice camera, but only 6MP, used the AF system out of the Elan 7 (a basic seven point AF) and was "the first DSLR to cost less than $2000".... it was $1999! Actually closer to $2500 with battery grip and several extra batteries.

Within a couple months of my purchase of the 10D, Canon introduced the Digital Rebel or "300D" in other parts of the world. It was also 6MP, but it was quite a bit less expensive (1st DSLR under $1500, if I recall correctly) AND it was the first model that could use EF-S lenses, the first of which were introduced at the same time. Another problem with the 10D was that it couldn't shoot RAW + JPEG.... it could only shoot RAW or JPEG. At that time we were shooting events and offering on-site printing services... we could take someone's photo and give them a print within a half hour. That required we shoot JPEGs. However, we also wanted RAW files to be able to improve on images in post-processing. The Digital Rebel/300D also didn't offer a RAW+JPEG mode, so I had to wait for subsequent models.

Rebels today can shoot circles around the $7000 pro cameras of 20 years ago! Today's cameras that cost 90% less have a better AF system, faster frame rate, higher resolution, better high ISO and a bunch of useful features that no one had even thought of back when the first Canon 1D-series cameras were rolling off the assembly line.
