As a 645 starter kit I picked up a 110mm, 150mm 2.8 and 50mm f4 shift.
And boy are they fine creations. |
Yep, these are some of the finest of the Sekor C / Sekor A line-up.

Are there more lenses in the system that stand out? The 210 looks interesting.

I have about a dozen lenses for the 645. The wideangles (the Sekor C 3,5/35mm and both versions of the Sekor C 2.8/45mm) obviously aren't useful on FF cameras - unless you adapt them with a shift adapter such as the Zörk.
On the other hand, there are a few really nice normal- and tele lenses. I wouldn't recommend the 1.9/80mm and the 2.8/80mm for adaptation on FF, since they are too heavy and have no real advantage over a good 85mm prime for FF (D)SLRs. The 4/150mm is OK, but not brilliant. The Sekor C 4/210mm is as sharp as the very best vintage 4/200mm lenses for FF, and the Sekor C 5.6/300mm is stunning - absolutely on par with celebrities such as the Canon FL 5.6/300mm Fluorite, the Canon FD 2.8/300mm Fluorite or the rare Nikkor-Ai 4.5/300mm ED "non-IF".
There are two stunning macro lenses as well - the Sekor C 4/80mm Macro and the Sekor A 4/120mm Macro (both are very, very good on 43 MP FF, no CAs at all. Optimal apertures are f5.6 or f.
The Sekor C 4.5/145mm "Soft Focus" is by far the most versatile soft focus lens I own (I have the Minolta 2.8/85mm Softfocus, the Tamron 2.8/70-150mm Softfocus, and the Leitz Thambar 2.2/9cm). It has the smoothest bokeh (Minolta is second, the others have a busy bokeh - not what you want in a soft focus lens), it's incredibly variable in the soft focus effects (again, Minolta is second, the others lack behind), and its long focal length helps to isolate the subject from the background. Certainly not a beginners lens - the combined effects of "Soft focus setting", aperture setting and distance as well as illumination (backlight vs other) are difficult to predict.
The two zooms I have - the Sekor C 4.5/55-110mm and the Sekor C 4.5/105-210mm - are very good as well. Since they were made for a larger image circle than FF (or even the common "medium format" 33x44mm sensor size), their performance is very even over the entire FF sensor: compared to common vintage FF zooms they have less vignetting, less CAs, better border and corner performance, and ... more wight, larger size and less speed
