Optical corrections for Canon RF 24-240

The issue is still not corrected.

The issue is still in DPL 3.3.

That’s a shame, as I am considering buying that lens. I wonder if Svetlana has any updates?

Hello,

It’s a question to @Marie.

Svetlana G.

I bought my software from DXO, not “@Marie”, so the question is for you too.

Hello,

I do not have the schedule of releasing the lenses while Marie has and this is the reason why I asked her.

Hello,

There are some issues of distorsion correction with low focusing distance (lower than 0.6m) on RAW images and we will improve the correction as soon as we can.

Marie

Please don’t be rude to Svetlana. She bends over backwards to help everyone on this forum. She is not in charge of everything DXO and was nice enough to direct you to the person who could help you. Please be nice.

My understanding of her response was “you should ask to Marie” which is not acceptable from my point of view. OK, I misunderstood, but I’m waiting since the beginning of December, so roughly 6 months from now with no news since March…
I’ll wait a while and hope it comes with the next revision.

Hello,

  • Let me just clarify, I didn’t write “you should ask Marie”. When we write ‘@’ before the forum name - it’s a direct notification to this person that a post needs his or her attention. So I attracted her attention to your post and you got the reply from her after that.

Svetlana G.

Yes,

sorry I forgot to pdate this topic.
We released a fix of the optics modules for the Canon RF 24-240mm on last Wednesday.

Hi - good to know that is now available. However will it be available for PL3, or only for PL4? Thanks

Hello @nputtick ,

modules correction is also available in PL 3.

Hi!
I think there is a new bug with this lens / EOS R in DPL4. At 24 mm, vignetting is corrected with the 1st “auto réglage DxO Standard” (sorry, I’m French, nobody’s perfect) and not corrected when using the 2nd “auto réglage : corrections optiques seules”, which is surprising as the “vignetting” box is blue in the two cases:

1st DXO Standard
autosetup DxO standard

2nd Optical corrections only
autosetup 2

I’ve found the explanation: in the second case, the image is not cropped to eliminate the black corners as in “DxO Std”.
It should be enabled to avoid that.RF 24-240 corrections optiques

I think it should not be enabled as this is the correct behavior for this “corrections optiques seules” preset.

The issue of this lens is detailed in this other post

where it is explained that this black corner is not really due to vignetting but to mechanical restriction of this lens.

Thank you, I hadn’t seen the other post so I continued with mine.
Anyway we found the same solution.
This lens is surprising and though there is mechanical vignette it is still a 24 mm when corrected and cropped: I made various testing ans comparisons with my other 24 mm lenses (11-24 ; 16-35 ; 24 LII).
