As Umut has stated, the Novar is a surprising lens, which is helped by the rigidity of the Nettar...one of the best aligning folders on the market. The only down side of a triplet is the wide aperture performance, but at 6.3 there won't be any problem at all!
Of course the Nettar was the basic back to bones model in the Zeiss catalog, but just sometimes less is more.
