Quite good (other than the mentioned issue):

Wow, at long last something to read. :)

ZOMG the distortion / vignetting... But it really becomes commonplace. Apart from that, if you treat this as an f/5.6 lens, it's really pretty good considering the sensor.

Another observation: if you do one more Sony E mount review after this one, the OPTICAL LIMITS UPDATES box is going to be filled up with Sony stuff. At least on mobile. :D

The next one is for Canon followed by a third-party Fuji review.

Markus is about to restart as well.

   I'm writing after BC's post btw!

   

...auto distortion has cropped the image nicely right in the corners....the question is now what is the effective focal length at the wide end when the auto facilities do their clever work?

 

  does it start off wider than 24mm to get  24mm after corrections?

The dark edges are not so much gone because of the distortion correction, but more because of vignet correction (realizing that after reading the review). Thats still bad... At least at higher ISO settings.

     I would have thought that 4.5% distortion correction would lose quite some part of the corners BC?....

 

            .......leaving the auto vignetting an easier task.

It's really the distortion correction that makes the difference here. The barrel distorted corners are stretched out. With pincushion distortions you tend to keep the corners but stretch out the middle part (alternatively you shrink the edges and scale up the whole image.

That digital correction thing doesn't seem lossless
Tried canon 750D plus 15-85 at 15mm versus Sony a6000 at 16mm corrected or uncorrected Canon is by far better, I can post 100% crops here if you want. But we are comparing a tiny kit lens versus a decent 800$ lens. So it's an unfair comparo results are to be expected.
I can try versus kit 18-55 if you want

If you look at how much gets cut off at the edge, and then look at where the corners will end up, you still are above 3 stops + worth of vignetting. So, I still say the vignetting correction is the main factor here.

Of course it is not lossless. That is not something you need to show, because everyone knows that?

If you have that 16-50mm lens - its only value prop is size really.  All the rest is ... meh.

Roger Cicala tested it on their optical bench at lensrentals.com : https://www.lensrent...4-105mm-f4-oss/

 

Looks like it's the best 24-105 on the market today (even slightly better than the Sigma IMO) while being smaller and lighter than the competition.

 

Interesting to see that the copy-to-copy variation is quite low. Maybe Sony has upped their game in terms of QC?

 

Well done, Sony!
