I beg to differ with the statement that the Tamron SP 150-600mm won't work on the R cameras without modification. I have both an R5 and a Tamron SP 150-600mm Gen 2 for over a year and they work perfectly together with no modifications to either other than the obvious inexpensive EF to R Converter. Before the R5, I owned and EOS RP and had a Gen 1 150-600mm and it worked perfectly and then I sold the Tamron Gen 1 and bought the Gen 2 and it worked perfectly on the RP.

I have the 24-240 and it is awesome, I use it 99% of the time. It is sharp and fast.

I have the Tamron 150-600 G2 and it works fine on my R7.

I have the R6 and use the adapter for 150-600 mm lens, takes great pictures, I do not need more than 20 MPX

I purchased the R-6 a few months ago. I, too, was looking at the R-5, but the extra $1500 was more than I wanted to spend. I also bought the 24-240 RF lens. I found the camera suits my needs. Bright viewfinder and LCD screen. Focus is fast. Loaded with the newest technology. I was gifted a brand new Sigma 150-600. A bit heavy, but I was surprised how fast it focused. Great reach for shooting distant shots. Only drawback is the R-6 has a 20mp. For what you intend to use it for, I think will fit your needs. R-6 w/ Sigma 150-600 lens.

The fact that the R6 uses a 20MP sensor is both a plus and a minus. More pixels is better for some subjects like landscapes... also better for cropping. However, a lower resolution also makes the camera more usable at high ISOs, better for low light shooting. So long as you don't crop a lot and/or don't make big prints, that 20MP might be fine.

Yeah, it [[b]IS[/b] a big jump in price to get the 45MP R5. The R6 with RF 24-105/4L is $3600... The R5 with the same lens is $5000. (Note, there's a less expensive version of 24-105mm, only offered in kit with the R6, where the combo costs $2800). Only you can say if the extra expense is worth it to you.

Between the three Tamron and Sigma 150-600mm lenses, I like the Tamron G2 is the best. That said, you will be adapting it because those lenses are only offered in EF mount.

You would get better performance out of the Canon RF 100-500mm, if you could stretch to that instead. It will focus faster and track action better than the adapted third party lenses. 100mm less telephoto focal length, but if needed it works very well with the RF 1.4X and that gets it to a competitive 700mm.

Of course, like all good things, the price is higher. The Tamron 150-600mm G2 is currently selling for $1200 and an EF to RF adapter costs $100 (or less for third party). In comparison, the RF 100-500mm costs $2900 and the RF 1.4X adds another $500. Ouch!

You describe yourself as an amateur wanting to take shots of your grandkids, family, kids sports and landscapes.... Why do you think you need a full frame camera to do that?

If it were me, instead of the 20MP R6 I would buy the $1000 less expensive 32.5MP R7 and put money saved into better glass like the Canon RF 100-500mm. And since the R7 is an APS-C format camera, giving the effect of a 1.6X teleconverter with its crop sensor, there would be no need for a 1.4X.

R7 with RF 18-150mm kit lens... $1900
Canon RF 100-500mm.............. $2900
------------------------------------ $4800

18mm on APS-C isn't as wide as 24mm on full frame, so with R7 you might want some wide angle. Canon's RF 15-30mm for $549 is one possibility. There also is the Canon RF 16mm f/2.8 for $299. Or for even less there are some even wider 10mm and 11mm 3rd party lenses that are manual focus/manual exposure. However, manual focus is pretty easy with ultrawides like these and manual exposure is easy on mirrorless cameras with exposure simulation preview, etc.

There also is the 24MP APS-C R10 which costs over $500 less than the R7.

R7 and R10 AF systems are essentially the same as R6/R5/R3. They all also share the same Digic X processor. The R7, R6, R5 and R3 all have in-body image stabilization (IBIS). The R10 doesn't (but all the Canon lenses mentioned above have IS). R6 is 20MP full frame, R10 is 24MP APS-C, R7 is 32.5MP APS-C and R5 is 45MP full frame. The R10 uses a smaller LP-E17 battery, so gets somewhat fewer shots per charge. The R7, R6, R5 all use the somewhat larger LP-E6NH battery.

Some Tamron lenses have needed a firmware update to work properly with the most recent R-series cameras. More current versions of the same lenses apparently come with the newer firmware version already installed. So someone buying a Tamron 150-600mm brand new will likely not see any problem. But someone who buys a used made in 2016 or 2017 or ? may need to have the firmware updated.

I'm still debating this issue. The R7 sounds good on paper with it's 33MP priced but that's like an 83MP FF sensor and that level of pixel density comes at a price - that price being a hit to low light performance and high ISO performance. From some of the reviews I've seen, things look great until you start bumping up ISO or lighting starts getting low.
For this reason, I just rented an R6 with an RF 70-200 f4 lens, which I plan to use alongside my 5D4 with similar lens. Going to take them both to the upcoming International Balloon Fiesta and do a ton of comparison shots under similar settings and then come back to compare. If I decide I'm happy with the R6 in terms of image quality, cropping, low light and high ISO performance, then it's the R6 I'm buying. If I find reason to be less than happy with the results then I may have to suck it up and get an R5 (yes, I know the R5 is "better" in a lot of ways, but I'm not independently wealthy). Going to see how things stack up with real-world use.

You have received some great responses, especially the one that provided comparative pricing. I use the R7 for grandchildren and their events and also for bird and landscape (at which I stink, but keep trying) photography. The 18mm wide angle on the kit lens is great and the camera performs very well in low light. The high MP density also provides much more editing performance even if you shoot JPG and not RAW. The incamera image stabilization also helps in low light situations. See if you can rent both the R6 and R7 and do some comparison shooting and also editing.

I have the R6 and the RF 100/500 and mainly only use it for birds. The RF lens is so much lighter than the Sigma and Tamron and is very sharp. I came from. 7d mkii and the EF 100/400L lens and the R6 does a lot better job. You cannot go wrong with the R6.

Basil Loc: New Mexico

My primary concern with the R6 (which I just rented) is cropping, but maybe with a monster lens like the 100/500 that wouldn't be an issue too often?

How often do you find that you can't crop as much as you need to without unacceptable IQ loss?

The R10 @ 24MP is like cropping a 60MP full frame ........and, SAVE $700 ....

"DLewis" don't want to argue with you, but, I called Tamron before I purchased my camera and tech svs said, "If I had the early one it will not focus and if it was the later version it will work if I send it to them and they will reset it"
Sorry I'm saying what they said to me. It made me trade in the Tamron and buy the Canon 24-240. Also have the Canon 100-400 now.
