I don’t see the purpose of it in our needs. 50&85/1.2 is a dream already.
The 135 focal length I get with the 70-200.
It’s too long as a one lens for all outdoor shots.
In Studio we use the 135mm for head shot, at f/4.
Could be I’m missing something. I’m open to suggestions
In my career as mostly a studio photographer, the 85 has always done the heavy lifting, complemented by 50 and 135. I always got the best/fastest available, not because I care much about bokeh, but because the understanding that these were developed specifically for portraits: how they render the skin (color and contrast) and how gently they transition to the oof region. I transitioned to the Z 50 and 85 1.2s and I now ordered this one.
The example you posted, in my work, would be done with an 85. The 135 is for faces at the optimum (for me) distance from the sitter. Half body is 85 and full body is 50.
The IQ will not be different from your 1.2s.
