Hi Dirk,
Mr Muller(with 2 dots above the u) mentioned about the new Biogon T* 21/2.8 ZM that Landscape or cityscape photos with rich fine detail,enlarged to calendar size prints,will easily prove the superiority of the new lens.
When using the new lens with a new order of resolution, I agree with you that the use and choice of instruments, in order to hold the camera steady, is very important. I would carry a rangefinder,a set of ZM lenses,HD film and a carbon fiber photo tripod. In this way I should be able to take the pic,enlarge it to calender size and be happy. Television tripod is a bit too much.
At this preZM stage, I am happy with my 21 distagon,G 45 2 planar and 100 2 planar. I am not happy at all with Distalgon 25 2.8, Distagon 35 2.8 and G35 2,so I will get the ZM 35 and ZM 25,so I am very pleased with the anouncement of ZM system. For 85, 85 1.4 C-Y is good but I wish to have something better,I will get the ZM 85 2 rather than 85 1.2 C-Y. N 85 1.4 is a bit big. Chi
