...the (earlier) question was which lens out of 135 or 180mm, given an existing set of 65, 80, 105mm ? The answer was 'neither' - postpone the decision and get a 55mm for now.
Whereas I liked the results from the 55mm lens I had for my Mamiya C330, but didn't like how relatively dim the viewfinder was when using it while photographing weddings.
I stopped photographing weddings, acquired a Mamiya 645 body or two along with 45mm and 55mm lenses, sold the 55mm lens for the C330 and now I'm happy.
As always, YMMV.

I had the 65, 80, 180 for my Mamiya TLR cameras until I realized that the 65 and 80 were too close together in focal length for my tastes. I sold the 65 and replaced it with the wider 55. The 55, 80, and 180 were the only lenses I used for decades.
I eventually replaced my worn Mamiya TLR cameras with the RB67 SLR cameras with 50, 90, and 180mm lenses.
