Am tempted as the upgrade for my 70D. The 70D will still be used for some things and has been good on hikes with a lighter lens as I only tend to portrait the dog on hikes.
What it will mean is all new lenses. There is an adapter but won't be quite the same. I'd also need a good astro lens but from a quick look, there doesn't seem to be much in an RF mount from Canon or Sigma that's suitable. Have I missed it? Will get a 28-70 and a 35mm to start with too.

Sorry I can't advise on astro as it is not my area at all, but bear in mind the EF-RF adapters work very well. I only used EF lenses for the first three years of using my R5s daily for work. I now have a couple of RF lenses (14-35, 24-70, 24-240) but I still use lots of EF lenses on my R5s and they work with no issues. My day to day kit is 35mm, 85mm, and 135mm EF primes and I have no plans to change them to RF. What it will mean is all new lenses. There is an adapter but won't be quite the same.

I'd second that. Some third part adapters are much cheaper than the genuine Canon article. However having tried one (name escapes me now ) and seen other negative comments the Canon variant I have seems like a safer bet.tog said:

I have feet in both Canon dSLR and their mirrorless camp. I use the Canon adaptor - its great and work seamlessly with EF lenses on an RF camera.
At the moment I have one mirrorless body and two slrs. So at the moment I'm using my EF lenses with the RF body. The next upgrade wlll be the other body, and I'll get a second adaptor, and then gradually retire the EF lenses and replace with RF lenses.

The other thing to consider is that second hand EF lenses can be had for bargain prices now as people switch over to RF and the used market fills with EF.
Was looking and the Sigma Art lens for Astro used is a 1/3 of the price on MPB. 
Just to add another recommendation for using EF lenses with the EF/RF adapter.
I've had an R5 for over 3 years, and have yet to buy an RF lens. In fact the last lens I bought was an EF 11-24 f4L a bit over a year ago.
I still occasionally use a 5Dmk3 as well as the R5, and when changing lenses, just leave the EF/RF adapter permanently on the R5 body.
The only thing to note (and I'm sure you're already aware of this), but as you mention the upgrade from the 70D, and using it on hikes with a lighter lens, if any of your current lenses are EF/S lenses, then these will not work well on your new R6 mk3, as they are designed for crop sensor bodies like the 70D, rather than full frame. Only EF lenses with the adapter, or RF lenses are suitable for full frame bodies.

Absolutely. - however I would add that some Canon RF lenses - and the 100-400 F8 is an example - are much (much) lighter than an equivalent EF lens, even without the converter. In my case the weight trumped the lack of weather sealing you might get with an EF lens and adapter. All depends on your use which factors weigh heavier.C n C said:

To get the best out of the camera that is correct, however unlike DSLRs you can fit EF-S lenses to full frame RF bodies (with the adapter), as there is no mirror to foul the back of the lens. The camera will automatically switch to crop sensor mode if it detects an EF-S lens mounted. I *think* all full frame RF bodies will do that - the R5 definitely does - but I agree that you would want FF lenses ideally.Message Board | Photography & Video | Top of Page | What's New | My Stuff
