Canon Rumors reader InsungFilms did up a good comparison showing the size differences between the RF lenses when mounted to the Canon EOS R body.
The RF 28-70mm f/2L USM is obviously the biggest of the bunch, but we're also surprised at the size of the RF 50mm f/1.2L USM, it looks like an impressive chunk of glass.
Also included for reference is an EOS DSLR and the EF 24-105mm f/4L IS.

Maybe there will be a lighter, cheaper model later on.
For portraits I have primes going down to 1.4 and which will probably be a lot sharper at the respective focal length.
Lets see if the pro body has IS.
The 24-70 2.8 II doesn't have IS either (if there is going to be something new, it will be heavier again for sure), and yet it is a lens I see the most mounted on cameras at weddings besides L primes (which are also not stabilised for the most part and barely faster than this zoom)
You go designing a unique groundbreaking lens and also somehow fitting an IS group somewhere there, as if this one wasn't difficult enough to design as is, most likely! It's not like IS is just some sort of a checkbox you toggle in the CAD software...
If the f/1.2 can retain some of that beautiful 'creaminess' while also being super great optically, this is going to be a really incredible lens. This announcement has had me all focused on the 28-70 and EOS R, but I think this is going to be a highly acclaimed lens. I wonder what next EF 50mm Canon is going to release? Seems like it would be strange if they release an EF 1.4L IS while the mirrorless gets faster glass.
Completely agree. Lack of IS was why I have held out against purchasing the 24-70 f2.8, and I had hoped that Canon would finally include IS due to Nikon including VR into their equivalent lens. Sadly it does not look like this is happening, and it just means I'll have to wait longer until Canon releases something with IBIS or an equivelent lens with IS.
Canon 24-70 2.8 II doesn't have IS and it's a stable in most wedding photographer lens arsenal including me. How did all these wedding photographers including me survive before IS?
No other camera manufacture have created something ground breaking in this zoom range as 28-70 F2. Not Nikon, Sigma, Zeiss, Sony, Tamron, Batis etc.
28-70 is already 3lb and some already complain about the weight which is similiar to Sigma 105 1.4 Art/70-200 2.8 II IS. They would have added an extra 4mm and make 24-70 F2 IS if it's an easy engineering feat.
Engineers have to make compromises on cost, size, weight, and optic performance and under marketing team decision.
Generally, there are still a lot of unanswered questions concerning the EOS R, including the adapter, which doesn't appear to be the "sexy solution" as described in previous CR posts. I guess we will be finding out in 2 days.
That's fine - but some form of stabilization is warranted here - if not in the lens, then perhaps in the body?
It would be nice to have IBIS in camera so we have to wait a couple more months to see what their professional EOS 5D mirrorless offer. 50 1.2 & 28-70 F2 aren't hobbyist lens so I expect Canon to come out with a professional EOS R in the future. If the 28-70 F2 is under $2000, I would order one right away.
I have Sigma 135 1.8 & 105 1.4 Art, 24-70 2.8 II and neither of those have IS with my 5D IV. I get by with these lens for wedding just fine.
No, not without extra optics in the adapter. RF is a mirrorless mount with a short flange distance (20mm compared to EF's 44mm). Time will tell whether someone will offer such a thing, Canon itself almost certainly won't.
So on that basis i would say Canon will produce a pro spec EOSR, because them lenses are definitely pro spec, i really can not see a 3lb lens on a 1/2lb camera. not for the normal folk (we are not normal)
