It is the only shot I found but I like it a lot!

Planned for 2nd half of 2019

Ah, the curse of the 85mm and the lemon bokeh balls :-(

Nice, but I wonder if it will be more costly than the just-introduced version?

I expected the DS to deliver more blurry background than the standard version of the lens but am surprised to see that the bokeh balls are so much more rounded with the DS as well. That definitely makes it an important consideration...

The DS looks nicer. However if it is significantly more expensive i think it would be wiser to buy the cheaper version as you can replicate the effect reasonably well with some careful local clarity and sharpness reduction in lightroom

It will.

lets note that it has a 1,5 stops loss compared to the standard version
I'd certainly expect some Tstop reduction. Where did the 1.5 stops come from? Is that published somewhere?

You really can't replicate the effects an apodization filter has on bokeh in Lightroom, particularly in transition areas from in focus to out of focus.

Only at the widest aperture, as with other apodised lenses. As you close the lens down the differences between the two lenses will disappear.

From what I understand an apodization filter, in effect, sort of reduces the aperture, as it's like a concentric ND filter, hence the T stop difference, and hence why the effect of vignetting is reduced, as it's like shooting this f1.2 lens at around f2 or so in that regard - you can see that the bokeh balls in the centre are quite a bit smaller than the regular version.

You can still see deformation from vignetting in some parts of the sample provided (lower right for example), so it appears that the filter isn't quite strong enough to fully obscure the edge of the lens.

Yea. It’s interesting to see the differences. The example images and the plain language explanations are very helpful.

You can to an extent. I have done so. Have you tried?

Here is a quick attempt

This is so strange, the bokeh balls seem to disappear with the DS?! I though there would be more not less balls.

And the balls that are indeed there, are much creamier and softer,

Overall, it looks exactly like gaussian blur not an optical out-of-focus rendition. It reminds me of how phones used to simulate DOF when they first came out they made bokeh like the DS image and when they got better they made actual bokeh balls like the standard version.

Overall I believe this would work better in an environment where there wouldn't be bokeh balls, like day-time wedding photography holy that would look creamy, but a contemporary night street shot I much prefer the regular one.

Now I need both. Well play Canon
 
There is a DOF gain (more (DOF) with the DS version btw
 
Will not double no. Loss is about 1,5 stops

IMO, the DS looks much worse. That Gaussian blur looks like a PS or a phone one. The centers of the bokeh balls are often blown.
