Second fail less than two weeks into the new year , just had delivered a Lomography ART Petzval 85mm F/2.2 in Canon EF mount .
I'll be using it both on my a7Riv and EOS film cameras .

I really need to start selling stuff instead of buying !

I also didn't want to spend $1000 on the Rokkor 250mm, and since I couldn't find an offer for $500, I was tempted to buy a new, supposedly similar lens: TTArtisan 250/5.6. (for $300)
The lens is for M42 and works with M42 -> LM -> LM-EA9 adapters.
In such a set I have AF on the Sony A7R4.

The donut effect is funny, but the sharpness seems good.
All shots (except #5) have a close focus point. The high rise is quite sharp, but I don't think it's a real birdwatcher lens.

The donut effect adds to the composition, especially in the last photo.
