Yes, very few are disappointed with the sharpness levels of all five APO-Lanthars, of which four serve duty on the E-mount system. There is nothing to speak of to separate them. They have also a beautiful color palette and controlled macro contrast.
The 65/2 has more obvious sharpness as it sees almost all work done at close focus distances, which lets the bokeh shine. You may occasionally see some busy asph-related bokeh highlights, such as p.83 #3 · p.83 #3 on the previous page. It was also the first APO-Lanthar released, back in 2017.
Here's a series from an autumn garden walk yesterday, 11/25, with a little stubborn summer color still hanging on. I'm really surprised this lens isn't more popular!
The Alpine Harebell (Campanula rotundifolia) were on full display this week in the Two Medicine area of Glacier NP.
It had rained the day/night before.

PS - I would not have been able to capture this (with the 18 focus bracketed images) without it being absolutely calm - something extremely rare in Glacier!
We have had a lot of wet warm weather here - part of the "atmospheric river" that is causing so much flooding on the west coast. Locally, this has resulted in the snow disappearing at lower elevations and a return of some mushrooms (which I missed a month ago)
Here's a little fellow I found Sunday going in some moss - it is only 1/2 - 3/4" in diameter. Lots of manual focus bracketing with the 65 APO starting at minimum focus distance. All natural light - nothing additional. Cropped in to about 90mm?
It is a great lens, I have one also. Have you tried cleaning the electronic contacts on the lens? If not that is quick and easy thing to try, though to be honest I do not really think that is it.
There are people on the forum that will take apart a lens and attempt repairs themselves, but I am not one of them. Or you might be able to find a teardown video on the net. I don't think cameraquest.com (authorized dealer) does any repairs themselves, but they may have some suggestions for someone who does. Also, keh.com has a repair service that I've read is pretty good, perhaps you could contact them and see what they think but there are costs to actually have them look at it. https://www.keh.com/shop/repair
