Okay - quick and dirty, but I think it's quite instructive all the same

The point is to look at the quality of the bokeh - in this instance I didn't have time to get tripod out, and anyway, the wind was blowing!

I'm going to post several sets of 3 images each set showing

1. FLE at f1.4

2. FLE at f2

3. APO at f2

I know that @alexreiterer said he wanted to compare at F2 (so I have) but it's also instructive to see how much the increased contrast of the APO makes it feel faster than it is. So I've shown the f1.4 as well.

FLE at f1.4

Final set

didn't get the focus exactly on the eyes for the FLE, but if it's the bokeh you're interested in then it shouldn't make too much difference

Glad you knew which lens was which!

The power of the APO certainly shows on the in focus element of protected plant, but the FLE is still a good lens and looking at the top right 'silver' highlight in the hound pix.

Good effort - hope @alexreitererappreciated the time you have taken!

Hah - well, to be honest I was interested myself, and the test didn't take too long.

I think it bears out Peter Karbe's assertion that the APO glass effectively rolls off into bokeh very quickly and nicely (this is why I included the f1.4 images). 

I might actually get a bit more serious about this and get out a tripod and EVF - Sadly in this screen shot the point of focus is different (both are at f2 despite what the exif says)

What you can see though is a little green CA i the OOF are on the FLE behind the point of focus and some pink in front . . . .  which is not present in the APO (which seems a lot sharper where it's in focus).

I'm always doing this to myself (ie doing a quick and dirty test and realise that I need to do it properly!)

Glad we're not the only ones who have dogs who think it's fine to get on the table, difference being no food involved for yours😊!

Yes indeed, she's a pyrenean sheepdog and thus not vertically challenged, but she usually gets on garden tables for a better view of the world rather than the kitchen table to steal food!. However, the previous pyrenean we had often jumped on the kitchen table, normally after the butter!

I think the most significant difference is the absence of purple infringement in the picture of your tree house.

Like this you mean?  this is a crop from 100% zoom both at f2

Our labradoodle can also get up onto a table and is currently in total disgrace for having chewed up three 120 rolls of Fujichrome. Obviously did not like the taste of the first one so having given that a chew, abandoned it and went on to the next two. 

On the APO lens, there is something of the look of the Zeiss 35mm/f2 Planar G lens but not quite as extreme. That had a very sharp focus plateau with a really abrupt roll off into Bokeh. However the big difference is that the APO's bokeh is very pleasant against the Planar's bokeh which was less so.

@jonoslack: Wow! What a great work. That is helping a lot. And yes the APO seams to be perfect. The bokeh of both lenses seam to be equal?!

HI Alex

pleased to be of service (better than working) I've started a new thread with some more 'careful' comparisons if you're still interested

That is very impressive work! Thank you. Whenever you are in the near of Freiburg i. B. just come in for a beer or a glass wine.
