I wouldn't exactly call the East German CZJ as world class. While a good value it is not as good as the West German Zeiss or Schneider lenses. Much better than Pentacon's own Meyer Gorlitz 300/4 lens though. The lens is designed for medium format so with the M42 adapter on it its light path is slightly compromised in the smaller format.

I suppose I should put the SMC 300/4 on my short list; I actually received it last year but returned it to the UK because I had ordered the 300/M. Now I want to consider only lenses with a tripod collar, which would exclude the SMC 300/4, I believe, but would include its M42 precursor, the Tak 300/4. But if I'm gonna give up K mount autoaperture, it had better be for a world-class lens. The CZJ auto-Sonnar 300.4 is world class. The Tak? I dunno; I fear I'd always think, "I should have held out for a 300/4.5F." Come to think of it, with the cost of larger filters and hoods, maybe I should just get a 1.4XL-A teleconverter and use it with my 400/5.6 PKA and 200/2.5 SMC. How much brightness does a 1.4 TC cost you: half a stop?
