Hi Tim, I have 4 lenses for my 645 J model and my favorite is the 150mm f 4. My photo gallery has quite a few shots using it. I have found the 55 mm wide angle sufficient for my needs and as one other has said rarely use the 80 mm. The 210 can also put out some spectacular portraits. The OOF areas for both the 150 and the 210 mm I find very pleasing.
