p.21 #1Back On Sale: Sony FE 20mm f/1.8 G lens for only $798 ($100 off)
What constitutes a bad copy? I took mine out the day after I got it and shot portraits. Loved the rendering, although there was distortion on the edges of the frame.

Would love to see this lens compared to the Batis 18. I love my Batis 18, but a smaller lens with the same focal length (?) and over a stop faster would have my attention, as long as the rendering is as good as the Zeiss.
I'd be curious, too, although that 2mm equates to a relatively significant (about 6 degrees) difference in field of view. I'd be equally curious to see them side by side because they're about the same size just different proportions -- the Batis is shorter but fatter (and lighter).
I bought my Batis when it was on sale for $899 a few months back, but I would have preferred to spend that same amount of money on the 20mm because I think it would be more fun to play with shallower DoF in an urban environment.

Earlier in this thread, there was some brief mention of actual focal length being closer to 18mm, but I haven't seen any updates.
Has anyone definitively determined whether this lens is indeed a bit wider than 20 mm?

I think some lenses are technically slightly wider than their official focal lengths to account for automatic lens correction being applied and chopping off some of the frame

I have the 24mm GM that I love but still am gassing for the 20mm 1.8. Enough of a difference? My gas says yes but I am still saying no. Plus I also have a 16-35 F4. Sadly sometimes my gas wins any rational argument though.

Yes, it’s wider than the Tamron 17-28 @ 20. I tested and posted crops on page 17 or 18.
I wish someone else would compare it against another zoom or Batis/Samyang 18. I think it’s 18 or 19mm

I've just got a well centered copy of the 20/1.8G and will test it against the 14-24/2.8, Loxia 21 and 24/1.4GM as soon as the rain stops.
My initial reaction is that there is visible astigmatism towards the corners which look great starting at f/4. Negligible field curvature, low CA and very sharp at center starting at f/2.8.

Still got a 21mm CV to throw in there?

Yes, on my tests I focused on the center and then looked at the corners, re-focused using the corners and then looked at the center wide open and saw hardly any difference in focus at all.
Yes, astigmatism in the corners, as per the MTF charts, but it's not that bad for non-point sources of light.

While I was intending to, here’s some real deal ghosting...like I said, not really a modern CV/Zeiss...
On a positive note, contrast is held well despite, so veiling flare not too bad.

So both you and Fred got a bum lens. That's alittle disappointing

With distortion corrections off (and thus some pincushion distortion, not a lot), I measured an implied focal length of 19.5mm at a distance of ~6m, using the vertical field of view so distortion would not be too much of a factor. Once distortion is corrected I don't think the focal length will be much different from 20mm. I'm confident it is not an 18mm lens or a 22mm lens.
