EOS 7D lens and accessory compatibility with EOS M50 Mark II

[Kaplang]

Will the Canon lens I use with my EOS 7D be compatible with the Canon EOS M50 Mark II ? And what about the battery, memory and wired remote shutter button? 
I’m considering getting the M50 if the 7D accessories and lens will transfer 

Thanks

It's not as dire as you might imagine.  The new lenses use a lot of composite compounds that are very light but robust - materials have come a long way in the last decades.  The main thing is the optics should be good, and I hope you will be happy with the results you get.

I'm comparing it to a Nikon F I was using many years ago. Still have it. Mostly metal and able to take a beating

Ah those were the days... I used an F1 as well but mostly Nikon F3 and Canon A1 units when I started. I still have one of each today.

As gear becomes more electronic its life expectation before most folks replace it is now shorter.

I still shoot on occasion with the Canon D30 Rel 2000 and D60 rel 2002. They are absolute tanks!

A lot of those older SLRs made it through the Vietnam conflict with a lot of abuse and came home in working order. Wonder if the plastic DSLRs of today are.able too?

Kaplang, I tried at least four 3rd adapters as well as both the Canon EF to R models. I ended up picking up both Canon's (two leave attached to 2 Sigma lenses) and i can say that I wasted my money on the Control Ring Mount Adapter EF-EOS R, the adjustment ring sits to close to the body and it's not functionally easy to make adjustments especially when shooting action. Buy the basic Mount Adapter EF-EOS R and watch the refurb section, when they are in stock they are $80.

The challenge with the after market, I found the focus to rack a bit and performed slower then the Canon. If you look at my older posts you'll find that I use 3rd party gear, this time they didn't perform. All my EF mount lenses performed great including my Sigma lenses. I would say that in my opinion they performed better on the mirror-less over my DSLR's.

If you have a decent shop by you I would suggest going and trying several out. Bring your lenses and have them show you the R50 and strap on some gear. I had the M50, it was a decent performing little camera and I got some real nice images. I traded it for the R50 and the foot print is almost exactly the same.

Just one more thought, the M50 like I said can grab some nice stuff. The challenge with the M50 is working it's way to end of life pretty quick, service if need will be a challenge and there is no adapter for the M to R if you move to R lenses.

No matter what you decide, good luck on your search.
