Canon announces the Canon RF 10-20mm f/4L IS STM
- Thread starter Canon Rumors
- Start date
Canon Japan does have the diffraction corrected version on their site. He sourced it from The Digital Picture - there is a rule in scientific literature, go to the original not reviews for accuracy, TDP got it wrong. Here are the correct MTFs for the EF 11-24mm.I think the 11-24 MTF is using the old method of calculating it, Canon changed it a few years ago to be more realistic (lower numbers), but Canon USA is too lazy to update their website.
You can recognise the old uncorrected MTFs immediately as they have twice the number of curves on them, one pair for wide open and a second pair for stopped down for f/8.

First time ordering on announcement day. Thank you, CR! (I did click on the link to B&H.)
Almost ten years ago I envied a friend's Nikon 14-24mm because of its sharpness and very limited distortion. Later I thought the Canon 11-24mm was just too big (and expensive by the standards of the time of its release).
But the size of this lens, the rectilinear optics, and the MFD of about 10 inches convinced me now is the time. Or whenever the lens actually arrives!
Plus, on a bit of a down note, I have never been ecstatically thrilled with the RF 15-35mm. If the 10-20mm is as good as promised, the older UWA zoom might be going up for sale, as I hardly ever use it.
Cheers!

Plenty of RF STM lenses offer electronic full-time MF, and several RF L lenses with USM don’t. It’s not about ‘deserving’ but rather appears to be about the age/firmware of the lens.

I stand corrected, thanks for the link! Time to have a look at the FTM settings on my cameras to see why I get different behaviour.

I personally don't care about whether a lens uses a STM motor or a USM motor. I use the RF 35mm F1.8 and RF 85mm F2 and think the STM motor is just fine. But I know a lot of people don't like (and I quote) the "noisy and slow" STM motor, especially videographers. That's what I meant this morning when commenting, but obviously it was too early (before coffee
)

If I hadn't bought the RF 14-35mm F4 a year or two ago, I would've preordered asap today. It looks like a really nice lens and the fact it is just 570 gr (still can't believe it) and it cheaper than its EF equivalent is really, really, really tempting, but spending money for just 4mm wider shots is just not happening. Furthermore, my decision nausea would hit new levels (RF 14-35mm or 10-20mm??????) especially for city travels
Enjoy the lens!

Looks like the R5 is going to need at least one more firmware update--for this lens.
Or will it?

Am I correct that if you want to use a CPL with this lens, then you buy filter cartridges that plug in at the mount end of the lens? I think Canon make these, but are there also 3rd-party filters that fit in these cartridge slots? Any information would be helpful + experience with the Canon CPLs.

You are not correct. If you want to use a CPL with this lens, you are SOL.
The drop in filter options are part of the mount adapter for EF lenses. That is an advantage of using the EF 11-24mm lens with an R camera. I use both CPL and ND filters in the adapter with that lens as well as the TS-E 17mm.
At some point, a third-party vendor may produce a front filter option for this lens, probably Fotodiox. They made them for the TS-E 17 and EF 11-24. I have the former, the filters are the size of salad plates (145 mm), the drop in adapter is far more convenient than carrying those around. The front filters for the 11-24 are the size of dinner plates (186 mm), filters for this 10-20 mm lens would probably need to be similar in diameter.

Damn you Canon! Just pre-ordered this one Been on the verge of ordering the EF 11-24 forever, now they do this...
When will you give me the 35mm 1.2L?!? I deserve it!

The US price is without taxes. The € price without taxes is about the same. On the other hand, the UK price is the usual Canon price gouging and equates to €3000. I would not buy it until available on the gray market. Shame on you Canon.

Instantly clicked pre-order and got stuck at applying for Payboo card at BH (apparently known issue for CA and VA residents).
Now with time to think, I feel a bit torn. Half the weight, IS, and 1mm extra wide vs 11-24 is absolutely amazing (how did they do that??), but I feel bummed at not being able to use rear filter for CPL and ND. What to do... why would Canon not make a drop in slot for filters like on the teles.

What does this mean, from the specs table?
| Filter Size Diameter | None (inserted in gelatin filter holder at the rear of the lens) |

I still don't get that gouging
