We're told that Canon will definitely release an RF 24-70mm f/2.8L IS in 2019. We don't think that is a big secret as Canon has mentioned there are a few f/2.8 zoom lenses coming next year. We also suspect a wide angle f/2.8L zoom is coming as well as an RF 70-200mm f/2.8L IS.
The same source says Canon will likely release an EF 24-70mm f/2.8L IS sometime in 2019, possibly as early as May 2019.
There were no details given as to when we could expect an RF 24-70mm f/2.8L IS, but suspect it'll be in the 2nd half of next year.
I'd rather have an RF 16-35 f/4L than an f/2.8L purely based on size and weight.
If Sony's lenses are any guide, they won't be any smaller or lighter.
Projecting a full frame image circle onto a sensor at a wide aperture takes a lot of glass, that's just how it is. It doesn't matter all that much if you move the lens a little closer or further away from the sensor. Opens up a few more possibilities for lens design, but still...
Also... So now this news comes out the day after I finally got fed up with Canon's lack of IBIS and no stabilized 24-70 2.8 and broke down and ordered a Tamron? :mad:
Also, are they really going to make both an EF and an RF 24-70 f2.8 IS? That's a really tough choice to make at this stage in the game, with the options for EF cameras much more rounded out than RF.
I mean I assume the RF lens will be the one that is more relevant further into the future, as I think RF cameras will eventually take over. But right now it seems kind of limiting to by an RF only lens if a similar one comes out in EF and can be used on either EF or RF cameras.
Even if the two are identically optically (which would be unlikely), and even if they were the same weight (again, unlikely), it's more than likely that the RF lens would have better autofocus speed and performance due to the new communication protocols. Whether that would be enough to make a difference in day to day shooting is anyone's guess. But you can be sure if there's a difference it'll be big in the marketing.
I hope the RF zooms are substantially smaller and lighter than the EF versions.

The 16-35mm f/4 IS (OSS) and f/2.8 GM Sony lenses are both a good bit lighter and smaller than the Canon EF 16-35mm f/4 IS or f/2.8 III equivalents (plus adapter) this is where some gain could be noticeable as opposed to standard zooms or tele zooms.
My Leica Summilux 35mm 1.4 is TINY compared to all these Canon beasts (including the 35L 1.4), and doesn't seem to have all that much glass. So it must be more a matter of the AF and IS motors, etc.
I'd like to think so, but I don't think they have the affordable sensor tech to be able to do that yet. If they do then the EOS R was just an emergency project to get something out quicker to take the wind out of Nikon's sails, while they complete what should have been the launch RF camera....

The 16-35 f/4 IS, the Sony is 518 g to Canon's 615 g. The Sony is shorter.

The 16-35 f/2.8 the Sony is 680g to Canon's 790 g and are very similar in size:

Similar to the RF lenses to EF, you seem to save 10-20% in weight. In some instances, this may be significant....but in most, I view this as pretty minimal. So, I would expect RF lenses to continue this trend (no adapter needed to the EOS-R), and be 10-20% lighter.
This is why I still see the place for the M series. They are very much smaller and lighter.
So while there's no doubt that an RF lens could be made with more advanced technology, quicker autofocus, etc than an EF lens, if you bought one at this point, you'd be limiting yourself to not being able to use it on Canon's most capable camera.
Like others have just said, this makes it more likely that a more capable RF camera will be announced before or at the same time as this lens, to avoid the conundrum of buying a more advanced lens but only being able to use it on a less capable camera.
I totally agree. But there are some weird people out there with only one camera body, and if that's an EOS R .. :)
How about 100-200mm F2 or 135-200mm F2?
Can Canon develop RF 24mm F1.4 or RF 20mm F1.4, for:
(1) similar image quality, but smaller and lighter? Or,
(2) similar size and weight, but better image quality?
To prove Canon RF does have advantage?
Who knows. EOS R could be their less ambitious camera that's why it's release first. They could be saving all the best tech with the best lens line up for their professional FF mirrorless camera BUT it means releasing later to work out some of the obstacles they had to deal with.
With Samsung entering the sensor market, I would love for Canon to use their FF sensor like Panasonic was rumored to use. Samsung can definite challenge Sony for sensor dominant.
