For those that have moved to the EOS R and are trying to use EF-S Lenses. I have found that not all non-Canon Lenses are compatible. This is documented in various places but is somewhat non explicit. In my case I had a Tamron 18-270 (B008) that would work ok but would not notify the camera to switch into aps-c mode ( this issue can be mitigated by manually switching to aps-c through the menus.) Additionally it had a problem with IS and it had to be switched to off.
I was not satisfied with the IQ so I decided to look for another FF lens to replace this EF-S (This thanks to the idea being put in my head by CHG Canon). Wound up getting a Canon 70-300 to replace the Tamron. No regrets at all on this unexpected purchase at all.
The point being if you are going to use EF-S lenses with the EOS R make sure they are Canon or are 100%compatible.
Agreed. I prefer to use like kind equipment, lenses, flash, etc.

Just a point of clarity. An EF-S lens is an APS-C lens manufactured by Canon. A Tamron APS-C lens with a Canon mount is, well a Tamron APS-C lens with a Canon mount, it is not an EF-S lens.
In the meantime both Tamron and Sigma are working to improve the operation of their APS-C lenses on the R mount cameras. For the more recent lenses from these companies (ones that can use Sigma's USB dock or Tamron's TAP-IN) I would expect to see compatibility firmware updates eventually.
Your right of course. I was just my thinking not what I actually meant.
Also I don't believe that all the firmware for each lens can be changed or is economically feasible. In either case I didn't want to wait around especially now that I found my IQ went up exponentially.
I would have waited for a native EOS Zoom but I think that will also be awhile.

I mentioned the newer lenses because distributing a firmware update for those lenses is not difficult. Older lenses would require a service, while with the newer lenses a simple download will do it.

CEH - you're missing the fact the Tamron 18-270 VC PZD already HAS stabilization built-in, and was designed in an era BEFORE FF MILCs … so, although it does a snap-up job with Canon DSLRs - this is another era. It's not surprising you ran into these problems. The Tamron is a perfectly good lens - but it needs to be used on the cameras (DSLRs) for which it was intended.
I do not deny your comments but at the same time I don't think I am missing the point. I was actually hoping that it would work as normal on my EOS R with the adapter. I could have lived with manually setting the camera to aps-c mode but I was worried that the constant ticking of the lens trying to stabilize would at some point harm the lens. The exercise was disappointing but I actually came out ahead in many ways except the extended reach.
Currently there are a number of aps-c lenses out there now that with the firmware upgrade and some without work well with the adapter.

Why would you want to use EF-S lenses on the EOS-R? EF-S lenses would work better on the cheaper M50 camera than the EOS-R.

Probably not, though - third party lenses with built-in stabilization … right, CEH?

1) If you are migrating from APS-C to FF it can be very helpful. 2) the EOS-R 4K video crop makes these lenses useful. A lot has been reported regarding the use of the Sigma 18-35 1.8 as a video lens on the R.

What's been said, DS?
What about the Sigma 50-100 f1.8?

i was just answering the question about why one would want to use an APS-C lens on a FF camera..

I would think - because you already OWN one (or many) and would wish to save yourself some money over buying new … would that make sense to you, DS?

I recemnty acquired the RP and retained Tammy 18-400. The camera does not automatically switch when the Tammy is mounted, but once manually switched, it shoots with no issues. I have the same function on 5D S/r, with manual switch, but have not tried the Tammy on that camera
