Canon officially announces the RF 24mm f/1.8 Macro IS STM and RF 15-30mm f/4.5-6.3 IS STM

It's not just about the cost of a rubber gasket for the mount. There are seals under the zoom/focus/control rings, under the switches, and around moving inner barrels (zoom, or focus as on the 50/1.2L). That certainly adds to the manufacturing cost, a lot more than 10-15 cents.
Regardless, it's very clear that for Canon, weather sealing is found only on L-series lenses. No L, no seaL.

The Canon USA Press release states:
"The Canon RF24mm F1.8 Macro IS STM, and Canon RF15-30 F4.5-6.3 IS STM lenses are scheduled to be available in late August 2022 for an estimated retail price of $599.99 and $549.99, respectively**.

Atleast with RF all L are weather sealed, for EF Canon was even more stingy with weather resistance and there were grades of resistance.
So that is why Canon India hasn't still listed these lenses in India and why no units were seeded to press/reviewers.

With only the available previews to go on, my guess is that the 24mm 1.8 would be as good as, if not better than, the 35mm 1.8 in terms of optical performance. If so, it could work very well as a landscape lens, particularly for those long hikes. My preference would be for a 20mm though as that would be just about wide enough to have fairly dramatic foreground. As for the 15-30mm, if the trend of RF design holds, I would expect it to have heavy distortion and vignetting with noticeably soft edges at 15-16mm, much like the 24-105 4-7.1 at the wide end. So psychologically, it would be more like a 16/17-30mm lens for landscape. It also seems to be designed more for vlogging, with the control ring having no audible clicking sound. Might be a good walkabout lens though.

Given how little leaks happened with this launch, its most likely was a launch pulled ahead of planned schedule or there were serious delays in shipping units to reviewers. Whatever the reason other than handful of retailers in Europe no one seems to have gotten any hands on time with new lenses. I will wait for reviews from usual group before deciding to purchase either of these 2 lenses.

I use kolari's filters with my r5 and rp cameras. They're awesome! They go inside the camera, just outside the sensor. So it doesn't matter what lens I use and it doesn't matter what the thread filter size is. Rf lenses, ef lenses, they all work. I usually put in the 6 stop nd filter and then swap lenses during the shoot.

Unless the RF version allows use of a drop-in filter, the adapted EF version is more useful, and will almost certainly be cheaper, too.

Hopefully these new inexpensive lenses will deliver decent image quality.
On a separate note, Bryan from the-digital-picture.com just posted the image quality for the RF-S 18-150 lens using the R7 body. What a disappointment! It is probably the worst lens Canon has made in many years.

The RF-S 18-150mm is the same lens as the EF-M 18-150mm – optically identical, same glass in a different barrel with the RF mount. The EF-M version of the lens had significant copy variation. When I was writing the review of the M18-150 for TDP, the performance of my lens was better than suggested by the ISO12233-type charts. Bryan tested a second copy of the M18-150 and it yielded better chart results (the second copy are the ones on the site).On a separate note, Bryan from the-digital-picture.com just posted the image quality for the RF-S 18-150 lens using the R7 body.

The EF-M version chart results appear better than the RF-S version, but the comparison isn’t ideal since the former is on the 18 MP original M, the latter on the 32 MP R7.

Pixel peepers beware! That R7, with its 32 MPs is going to cause you much consternation! But look at your images full size and everything will be all right!

I did a test-chart comparison with the RF24-240 (on R5) and it seems to me that the RF-S lens is much worse. Disappointing for the RF-S lens indeed. I thought it would be better. Perhaps bad copy, and perhaps images look good once they are printed. We'll wait and see.Hopefully these new inexpensive lenses will deliver decent image quality.

Thanks for the link, thought I'd do a comparison with the EF-S equivalent, and to be honest, I'm not seeing much of a difference between theHopefully these new inexpensive lenses will deliver decent image quality.

Canon RF-S 18-150mm F3.5-6.3 IS STM (Canon Store: $499.99) and Canon EF-S 18-135mm f/3.5-5.6 IS USM lens (Canon Store: $599.99). The RF-S lens looks a hair sharper in the centre at 18mm, is $100 cheaper, but the EF-S lens looks a bit sharper at all the longer focal lengths in the centre and edges, and is 1/3 stop brighter at the long end f/5.6 vs f/6.3). Also wondering whether the RF-S lens is being massively software corrected at the wide end???

EF-s looks a bit sharper to me, but not much. I have this lens on the 90D and am very pleased with the pictures it delivers. The RF 24 is twice the price: should be twice as good......

You are wasting your time drawing conclusions from those charts from TDP. First, you are comparing images from a 32.5 Mpx sensor with those from a 20 Mpx, and then the comparisons are not that reliable. I have found many examples when comparing my own lenses side by side with radically different results from conparing the TDP charts.

ps, Canon's own generated MTF charts, corrected for diffraction, are about as good as any guide. But, all that counts is how good is your copy on your camera, which will depend on copy variation of the lens and the conditions you use. The charts show the RF-S 18-150 is sharper at 18mm and it's the lens itself, not software correction. The RF-S 18-150 is very good value as part of a kit with the R7 and R10.
