Philippe, you could always add a 105 f/2.5 to your kit to cover that focal length at a considerably reduced price. It is always a pleasure to see your work on this thread and every new MF Nikkor added to your kit increases the likelihood you\'ll join us.
I don\'t believe you were here when a former member of FM, Todd Adamson, was sharing a comparison he did between the Zeiss 100 and the Nikon 105 f/2.5. The Nikkor didn\'t do too badly. It was a bit like the 1973 Stag\'s Leap cabernet sauvignon that turned a few heads in Paris so many years ago...
He did a first comparison and then after receiving comments did a bit more elaborate comparison adding the Nikon 70-200 to the second part. Just for fun...
