It is indeed a specialized lens, but that's not necessarily a bad thing. The same could be said of the 135/3.5 Planar or the 150/2.8 Xenotar--they were designed to be sharp wide open with a tight image circle for handheld press camera use. I use the 135 Planar, cammed for my Tech V, handheld, and I have a 135 Caltar II-N (Sironar-N), if I need a 135 with a larger image circle.
