Another RF brick landed in da lab

Wim, the bokeh is not great. It's also not great in the normalized test.
Specifically - it blurs nicely if the contrast of an edge is moderate but it has issues with harsh transitions.
I reckon this relates to the rather unbelievable resolution capabilities.

   .....  this hanging basket image is of "such poor quality" ...... it's shredded ....... 
  


  ....... it's pointless judging a $3,000 lens from smugmug images IMHO.

It is not too bad for grass (see Oly Pro 40-150 Smile).

I use it for reportage type photography (events) and portraiture mostly, and it is just stunning withthose subjects. I'll see if I can get permission to post an image or two. Privacy regulations have prevented me from sharing pics recently Smile.

Kind regards, Wim

P.S.: In contrast with the EF 85L II, it has both great bokeh in foreground and in the background, and none or very, very limited doubling of lines in the background (which the EF 85L has in abundance)..

   The review shows this lens to be an excellent portrait lens indeed with very little of the rendition problems from the other images we've seen here .....

Review tells that that APO lenses tend to have weaker bokeh.  I cannot judge this sentence.  is it correct or not I leave it to experts in this area.
My experiencee is that my best performing bokeh lens is Tokina 100 Macro - It has a lot of CA and LoCA. I still keep this Bokina 100 macro lens.

Dave, Dustin Abbott called it a very intentional lens.  I think you are right, it produces great portraits.  Great sharpness and texture rendition.  I sort of regret my knee jerk response to defend a Canon L lens and know have to say Klaus was on target with his comment on the OOF grass.  Even Dustin's example of how well the background is melted away at distances close to MFD (in that dried straw colored plant photo) the photo of the plant actually looks slightly streaky, and there is some doubling of some parts.  Also there is very little anywhere in the background there to melt in the first place.   I think maybe the doubling effect requires not just contrast, but a certain amount of thickness (angular width) for the nervous doubling to occur.  So even stray dark hairs against bright white don't cause the problem, but something the thickness of straw or grass does, even though there is not nearly as much dark/light contrast. 

Anyway I appreciate the strengths and weaknesses of this lens a little better.  While it is not the type of lens I need, I'm sure I would be taking everybody's portrait if I had this at my disposal!  So, a belated thanks to Klaus for pointing this out.  Forgive an old Canon user for not being more objective.

BTW, I have actually not heard that.  Do you mean:


- Forget photography and invest in real estate.                      
                       or
- Bricks are more photogenic than grass.
                        or
- Or something I will probably never understand!

It's an English expression which holds well over time ....... it you knew the steep rise in English house prices you would know what I mean ....... 
 ....... a play on words between brick lenses and the real bricks!

As for the Canon 85mm ...... I didn't find the grass shot bokeh so bad behind the focus point, which is where it counts ..... but as you say this is portrait lens and may not double as a telephoto ......

....... however, as always I reserve judgement until I see a lot more than a couple of images .....

....... my dream portrait lens is the Nikkor AF-S 105mm F1.4 ....... which has occasional instances of bubble bokeh ...... which might "ughh" some .... for me it's the only portrait lens which completely wowed me ....... but then I get by with my lowly AF-D 85mm F1.8D ..
