New RF 16mm has quite some vignetting at F2.8 - (with no Lightroom lens profile yet)

That’s basically fine. Sure for a prime lens distortion should be better, but it’s an affordable fast ultra wide angle lens. By f5.6 vignetting is gone. Good show.

Gotta remember it's a Full frame f2.8 ultrawide and it's the size of a nifty fifty and costs $299. We all knew there would be compromises.

exactly.  i had the sigma 14 1.8, 20 1.4, canon ef 16-35 2.8ii, tamron 15-30 g2, and i'm more than happy to exchange the weight for more time post processing.

Both the Sigma and the Canon 15mm seem to work well as a donor and then reduce distortion to around 40 to taste.

One of many reason I dumped everything Adobe years ago. LOL Use it at your own peril.

This thread is OLD. Adobe has had a lenses correction profile for months.

yeah but nothing has otherwise changed about Adobe. They still suck

The autocorrection crops the image considerably.

The DPP4 auto correction for this lens gives exactly the same field of view as it does for the EF 16-35mm f/4. PhotoLab gives a slightly larger field of view. I have both lenses now and have compared them.

12mm field of view. I hid the superimposed distortion corrected image layers for clarity, just leaving the frames.

When you correct barrel distortion manually, you end up magnifying it to a greater degree with increasing distance from the centre. As the ends are further from the centre than the sides, and the corners are even further, you would end up with an image with roughly parabolic concave sides if you didn't crop it at all. For the amount of barrel distortion this lens has, the largest rectangle you could crop out of this curved shape has an aspect ratio close to 16:9, which means that using PhotoLab I can get a field of view with this lens a little wider than a 16:9 crop from an image cropped at 16:9 from a 14mm rectangular lens.

I took a photo of a brick wall and have the jpg and the cr3, of which I corrected the latter manually. The FOV of the cr3 is about 10 degrees more than the .jpg.

I compared it with the Samyang 14 before I sold the latter and saw that the FOV is with manual correction the same as the Samyang 14,

But in both cases the IQ is very good for such a cheap lens and I like it even more than the Samyang 14 as the latter is heavy and bulky and its 'moustache distortion' is more difficult to correct, despite having a lens profile in Affinity and Photoshop. Both apps lack a lens profile of the RF 16, but correction is much easier.

The profile for RF16 was released for six month ago for Lensfun (Affinity).

If that’s you, you’ve been doing a great job keeping up on releases. Thanks. I noticed the 100-400 is available too.

At Lensfun and its database the vignetting correction data is still missing. You can manually copy from the print screen below or just copy paste from the xml file at my page .
