Seeking opinions on Mamiya 645 210mm F/4 Sekor C Lens

Hi, I am partial to the 135mm focal length on 35mm cameras ever since I tried it. I have a Canon FD 135mm f/2.5 that I enjoy using and it seems this is pretty equivalent to the 210mm f/4 Sekor. Have you tried and liked this medium format lens? I've seen the whole range of opinions searching online.

I have a 180mm f/2.8 Sonnar medium format lens that I love but it's heavy for travel. Outstanding results though, even with a teleconverter.

I have one and find it fine to use.
But you should understand that I'm partial to wider angles, and a relatively infrequent user of longer focal lengths.
When I do use them, I tend to use them to either compress perspective, or to make tight portraits.
Neither such use is particularly demanding optically, but then I rarely "focus" on the highest degree of optical performance, when considering lenses which are of generally high quality. That 210mm lens is in that group.
It isn't small, but it is the same filter size as many of the Mamiya 645 lenses, so it has that going for it.
