The two probable points of improvement will probably be AF (mostly the silent thing) and aberrations, where indeed the 77 is somewhat lacking because of the design choices made at the time.
However, those design choices were there for a reason. The rendering capabilities of the 77, its bokeh, and moreover the transition from in-focus to out-of-focus, is what explain the 3D pop that the FA Limited have. Simply put, as a test bench equipment the 85 is sure to vastly outperform the 77. But as a creative tool? Not so obvious.
Having
compared both, I agree. Still, having tested the D FA* 50, by "normal" lens of choice remains the FA43 to this day.
That's a much more sensible way of putting it, I think
Yes I know. People get to define something by whatever criteria they decide to use, generally to backup a narrative.
So, I define it by sharpness (resolution), contrast, flare control, lack of aberrations, especially fringing (something the 77 suffers badly from), and while this is not quite as easy to measure, bokeh and 3 dimensionality of the image.
For me, a secondary consideration is AF speed, again something the 77 is not especially known for.
Also, I can guarantee you that the new lens will outperform the 77 at f/1.4.
The 77 will win on size, weight and cost, but none of these are performance criteria, though people will certainly try to classify them as that (see my first sentence in this post).
Creative people can use anything to create, I think the "creative tool" thing is a red herring.. However, if the equipment is limiting, creativity can be somewhat hobbled. This will be a heavy lens, people might find that this limit's their ability to create, but one could also sy they are limited by their own physical performance.

While I could/would accept it in case of standard or kit lenses, I can't accept it when it comes to a * (premium) lens.
I'll keep my Sigma (KAF3), which works fine on my K-7 (10 years old).
Full backwards compatibility for lenses is a thing of the past. It's something we just need to get used to.
