The 55mm lenses are of variable quality Brad I had to try four new ones when they were current before I got a good one, and the dedicated Mamiya hood http://www.ebay.co.uk/itm/like/2314...4543&item=231400405016&lgeo=1&vectorid=229508 is essential to deal with the flare problems it's prone to, the 135 is a wonderful portrait lens I love mine.
Yes, I think that the hood would have helped a lot.
