R-series equivalent to EF-S 15-85?

I do a lot of travel/architectural photography, much of that in the 15-20mm range.  But I also shoot relatively frequently in the zoom range 50-85mm  For me, the EF-S 15-85 has been the lens practically glued to my 60D.  (I also have the Canon 10-18 and a 75-300 zoom.  The latter is usually used for photos of gargoyles )

So if I move to a Canon R-series (thinking about the R7), should I go with the adapter for the EF-S lens?  Any hints from Canon about an R-series equivalent range?

18-150. Adapt the 10-18 for now.

I'd lose a lot with that, since I'd guess maybe 1/3 of my shots are 15-20 range.  Plus, of course, I'd be at the absolute edge of the lens, where problems are noticeable even to my eyes.   (I had the previous 17-85 EF-S lens, and noticed the extra 2mm on the wide side was a big gain.)

There are literally 3 RF-S lenses on the market right now, none reaching 15mm at the wide angle.

So it is either adapt EFs, use RF full frame lenses on the R7 (none equivalent to the 15-85), move to a full frame body + kind of similar 24-105mm or wait

Its help a bunch if you fill out your gear list, how are we going to give a good answer if you don't ???

It took me over two years to replace my EF with RF.  I still have 3 adapters.  The longer you wait the less you will get for you EF stuff and the more RF will cost

They will probably eventually launch an RF equivalent, but there is no news on that yet.

An RF camera will treat your EF(-S) lens natively, and you get the various mirrorless advantages with those lenses. And the adapter only adds back the space that was there on the DSLR, so mirrorless + adapter + lens isn't any bigger than your old setup.

As another user mentioned, drop-in filter adapters (personally, I have a Kolari one with Kolari and Breakthrough filters) are also available and let you stick filters on any EF(-S) lens. A nice bonus capability if you get that too, though most of the time I just use the regular adapter.

In short... You have the EF-S lenses. They are 100% compatible with the R7 (and they actually work better with it). If you are happy with the EF-S lenses, just keep using them. You could always get a different lens later if you are interested or one intrigues you.

There’s no sign from rumor or patent that Canon with replace the 15-85 in a crop format to answer your question. However, you may want to have a hard look at the R8 and it’s 24-50, then. FF though.

Adapting is an option too of course if you’re married to crop glass or crop shooting conditions.

Anyone care to speculate why this seems to be the case? I wouldn't think there was a technical limit on mirrorless that makes ultrawide zooms more difficult to design than for DSLRs.
(I'm still lusting after an R7, but I'm hoping for a price break.)

Of course it isn't any more difficult. Any DSLR design is a valid mirrorless design.

The real reason why it doesn't exist is because there isn't enough demand to make it a priority yet. Of course, you can use the current 15-85 in the meantime, if you want that.

There’s not a technical limit. Just no desire by Canon. The only answer I have is perhaps they consider zoom lenses that start at 24mm, a luxury, and reserve them for luxury offerings, think L, FF, G series power shots. Canon broke with that with the EF-M 15-45, but that’s it. Perhaps that was to counter competition, which APS-C competitors right now consist of Fuji, which the R8 has pretty much silenced.

If you must have a zoom that starts at 24? R8, or M, or Fuji. Sonys rumored to be up to something with crop shortly. We’ll see…
