Q2 and DNG geometry crop

I noticed that removing the automatic geometry correction of DxO the field of view widens a lot

The automatic correction in jpegs forces a 3:2 aspect ratio, while the raw one seems like a 16:10

I think that this is normal but the uncorrected raw seems nearly perfect without any critical distorsion or vignetting

It's like having a wider lens

Here is an example

Thanks for posting those results.  I think most of us knew that lens correction would crop a bit to eliminate the vignetting, but doubted that it would be quite that much.  I wonder(just thinking out loud) if aperture would have any effect on the amount of vignetting or how much the correction would remove.  From the original post I'm guessing that smaller aperture would create less but the correction will remove the same.

In the german forum we had a similar discussion about the 24-90 - just the same

Even with the Q1, initial comparisons showed that the lens tends to show the angle of view of a 26mm lens. Since no one wants to have a 26mm lens, they write 28mm on it. That is not uncommon. The focal length sold is often a bit of marketing and variations have always been normal. Hardly any of the 50mm lenses sold for years really had 50mm. In the very early days, the variance was also engraved on the lenses. At some point they stopped doing that.
