Canon officially launches the RF 28-70mm f/2.8 IS STM

IQ: I'm still skeptical.
How good will a non-L zoom lens be?
On the other hand, I was skeptical about the IQ of the RF 2/85mm, till I tested one. Now, it's part of my light kit, thanks to its impressive optical quality.
And "only" 28 to 70 sounds good, less range could mean less optical compromising, in relation to the selling price.
So, I'm waiting for OpticalLimits and TDP to review it. Unfortunately, no need waiting for Gordon Laing's review, all the latest, and even older Canon lenses' reviews are described as "so far", and nothing comes. A pity, because, unlike most other reviewers, he took real pictures, no ones of charts. The only way of testing I trust.
Gordon, please, resume your testing!

I suggest, since it seems to me that you are using the EF 16-35 f/4L IS USM on the R body, that you try a drop-in adapter with a V-ND filter, and if you also need an additional filter, you can always use it put on the front end of the lens.
I don't have an issue using the 16-35 with my LEE filters. But if I would switch to the RF 10-20 I have look for a different/new solution (give up the LEE-filterssystem) One of the criteria is flexibility of using combination of filters and of course minimum impact of dirt getting into the camera.

For all those "cripple" complainers (not addressing you, Del Paso!), I'd really like to know how much bigger that lens would have been if we add 4 mm on the WA side or 10-15 mm on the tele side.
Apart from the price, it would have become reasonably bigger and less attractive.
This lens for sure is a compromise, but I suppose an excellent one.

Canon claims it's as good as the RF 24-105mm f/4 L, or slightly better.





I don't understand polish, but I understand the RAW files on the description:ROFLMAO:

@Richard CR , I think you hit the nail. Thanks for all those comparisons.

Personally I prefer 105mm of the f/4 over f/2.8. So I will stay with what I have.
But I fully agree, that it's a great partner for travel (e.g. for the R8).

Now let's hope for an constant f/2.8 RF-S zoom for the APS-C users.

The Sigma RF 18-50mm F2.8 is a great option here. I'm very happy with it.

I think I'll go pick one up tomorrow. Everyone loves it.

I wrote "Everyone should have one", so I bought 2 - one extra for my wife. At 1m distance, its 0.4x magnification make it a superb near macro lens for insects that are skittish when you get close.

I think the weights got switched in the table in the article. Shouldn't the 28-70mm (missing an m in the table header) be 495g?

You're right. And still the data is shifting. They should switch the titles in that table ;)

Canon Germany claims
490 g for the RF 28-70mm F2.8 IS STM and
395 g for the RF 24-105mm F4-7.1 IS STM

also the dimensions are altered here
76,6 x 88,8 mm for RF 24-105mm F4-7.1 IS STM and
76,5 x 92,2 mm for the RF 28-70mm F2.8 IS STM

28mm for life! (I'm still whining for an RF 28 1.4L)
The Sigma is good not great. They're so cheap I could recommend buying one next time they're on sale or used. I've had trouble getting photos due to MF but not due to the resolution being probably nominally lower than we'd expect for an L prime. But yeah, I had both the EF35/1.4 MkI and 24/1.4 the instant they came out and for me the 35 was just too normal and the 24 was almost unusably wide. (I take 24mm shots a lot with a 24-105, but let's say only 1/4 of them were 24mm or at least could have been 24mm. So when I mounted the 24/1.4, I'd take like at most two photos in a row with it then simply have to switch back to something else.)
