Everyone is right here, there are so many excellent cameras out now at all price levels and from so many makers, it is hard to go wrong with any gear. Even the older, reliable stuff still makes good images. So no need to go into debt for the latest thing . Use the gear you need to fit your vision and the gear that fits your budget and be happy.

I have been fortunate to take a hobby into a long successful professional career. And that has allowed me to afford some excellent gear over the decades. But when I teach photo courses to my university students, it is not all about what gear they don't have, but about making the best of the gear they do have at any level, as they create.

You dont need a camera that shoots 4k or 8k video if your screens only display HD. And you dont need a 50mp or 61mp still camera if your affordable lenses cant resolve enough for that expensive sensor.

The majority of UHH members here are not professionals, and dont need gear to meet professional duties. As enthusiasts we all want gear that we are comfortable with, like an old reliable friend . If you already have that old reliable friend, ignore the GAS and look no further. Cheers

Barb, there are mirrorless cameras that DO NOT overheat, and DO NOT have recording limits. I use a Lumix GH4, which has never overheated in five years, despite recording in 95°F summer heat for over 90 minutes. At low video bit rates, it can record about 2:20 on a new, fully charged battery. Heck, the battery dies, or the memory card fills up, before it even gets warm.

The GH4 successor, the Lumix GH5, and its sibling, the GH5s, don't overheat, either. They can keep going indefinitely, if you use a battery eliminator AC adapter and keep swapping out the SDXC cards in the dual card slots. The full frame Lumix S1H includes a fan to cool the sensor, so it does not overheat, either.

Of course, some full frame cameras *do* overheat after four minutes of 4K video recording. Others overheat after 12 to 20 minutes, and most have a European tariff-limited record time of 29:29:29 (Minutes:Seconds:Frames), anyway. The GH4, GH5, GH5s, and S1H have no time limit restrictions.

That's the difference between marketing gimmicks and purpose-built cameras. The folks at Panasonic put some of their best video knowledge into these cameras, for those of us who NEED both stills and video in the same package on a frequent basis. They are not perfect (Contrast-Detect AF is weak for stills and awful for video), but that may or may not be an issue, depending upon what you record. Cinematography is most often done in full manual mode, anyway, so multiple cameras can be matched for color and exposure, and there is no chance of focus "hunting."

IBIS is not exclusively a mirrorless function. Three of my four DSLRs have IBIS, while only one of my five mirrorless cameras have it and on average my mirrorless cameras are newer! It's certainly a useful feature to have available and in the latest incarnations is much more powerful than in my older DSLRs. It's true IBIS is more useful on mirrorless - where the viewfinder is also stabilised which makes a big difference if you're shooting at 500mm or more.
The magnified zoom in the viewfinder is another nice feature available in all my mirrorless cameras & missing from the DSLRs unless I add an extra bit of kit. It does come at the cost of a slower digitised view, but its rare for these disadvantages to show in use - the viewfinder lag is generally a small fraction of my reaction time (only getting slower when a DSLR would show nothing) & modern EVFs are high enough resolution they are effectively unpixelated. I suspect many die hard DSLR users (who swear they'd not consider a EVF) have experience of one of the very early EVFs an allow that to prejudice them - modern EVFs are nothing like the early ones.

If you have the funds and don't mind spending them, then I suggest going with the mirrorless.

I have had my 6D for several years and have been very happy with results because it has been a beast, helping me to produce many great photos.

But I decided to switch to mirrorless, first the EOS R and then to EOS R6.

I am very pleased with the R6 especially since, for me, it opens up opportunities for improvement that would have been more challenging or not available with my 6D.

The IBIS and focus peaking are great for allowing me to use my vintage manual focus lenses with a lot more success; with the 6D that was pretty much hit or miss or more time consuming to get sharp, stable photos with these.

Of course the flip screen helps greatly with taking macro shots and other low-the-ground photos; option not available with the 6D.

Low noise shutter sound, faster autofocus response, eye autofocus for people and animals are all advantages over my 6D.

Only two downsides I see are shorter battery life (using my 6D batteries as extras) and lower megapixels but neither not major issues for me.

Yes, you can still take great photos with the 6D because it is no slouch, but I have essentially retired my 6D and 7D2. Will eventually sell the 6D and keep the 7D2 for occasional use mostly for wildlife or as a web Zoom camera (works great).

Bottom line if you have the fund free and clear, for the Canon mirrorless (R6), I don't think you will be disappointed.

I like the EOS R but not as much as the R6. Using the R mostly for landscape and R6 for action photography.

Barb, the image quality of the 5DIII is hard to beat, especially at high ISOs. This camera was very popular and used prices are now well under $1000, reflecting the huge amount of bodies in the market, especially with people turning to superior mirrorless bodies. Mirrorless bodies have features that make the shooting process better. The IBIS turns every lens into an IS-enabled lens, something I like about using my old manual focus film lenses on the Sony. The 10x zoom in the viewfinder, with the camera held to my eye, gives me the ability to focus on anything as I can 'see' the details. You can also do an image review in the viewfinder, for all those situations you can't 'see' the backside LCD due to being outside in bright light.

Over the last few years at our camera workshop I would say DSLRs tend to be preferred by the older men, all the mirrorless cameras have been owned by members under 65 (several of who have DSLRs too). The more decrepit members have all shot DSLRs except for one with a bridge camera.

Personally I use both, my DSLRs are slightly better for fast moving subjects like airshows & motorsports.
While the mirrorless are streets ahead for adapting lenses, infra red, and low light. (This also helps out in macro where a DSLR viewfinder becomes very dark as the magnification goes up).
For the majority of other types of shooting both are very similar in use.

I don't shoot video but I guess that tends to fall on the mirrorless side too.

If your usage fits in the areas where mirrorless excel then I'd strongly recommend you give one a try (borrow a friends, rent or try in a shop). this might be a good thing to do anyway just to see how you get on with them.

Hey Barb, all your EF lenses will work just as good, if not better, on the mirrorless body. Personally, I have a still excellent EOS 5DIII and no rush / need to change. I added a mirrorless Sony a few years ago just to use old manual focus lenses from the 80s. The mirrorless platform is the future with the cameras being better than their DSLR counterparts today.

If money is not a limiting factor, getting a mirrorless camera is the best new camera to consider. Fixing your current camera would probably be the cheapest, as well as looking at options of a used EOS 5DIII, or 5DIV or the 6DII. The Set button is rather important to the full-frame EOS bodies, so I can appreciate the need to either fix or replace with a reliable body. These advanced EOS bodies are build to last for the long-haul. I plan to push my 5DIII for a full 10-years or a catastrophic failure, whichever comes first.

Hey Barb, one outstanding question from earlier is what lenses you have already as that tends to impact your decision making.

Regarding video and for confirmation, how much 8K video do you record today? How does a 20 minute limit at 8K and up to 15 minutes in 4K 120fps impact your intended EOS R5 usage? It seems this technical concern would be difficult for you (anyone) to encounter except for someone who's job is to find where a new camera breaks.

Regarding the 'set' button, now that you still have the problem, have you considered getting it properly repaired? Have you considered getting a quote from Canon and considering if a repair is the cost-effective approach vs buying a new $2500 EOS R6?

Barb, you probably want to use <Quote Reply> as you work through responses.

Canon is actively moving away from DSLR technology. They've officially said they're not releasing new EF lenses. They don't have any DSLR bodies listed for 2021 release, even if they haven't said officially they're stopping DSLRs. Neither of these plans 'hurts' any existing DSLRs. But, if your DSLR body has an annoying problem, that could be a reason to consider a new body. Also, if Canon did the repair, consider if the warranty on that repair is still active.
