Gabriel66 Posted July 25, 2015 Share #1 Posted July 25, 2015 (edited) Advertisement (gone after registration) The first 90 pre-Summicron M asph had the hood covering the aperture ring. It 'a lens common or rare? There are differences with the standard model?

Advertisement Posted July 25, 2015 Posted July 25, 2015 Hi Gabriel66, Take a look here First pre-asph summicron 90 made in 1977. I'm sure you'll find what you were looking for!
luigi bertolotti Posted July 25, 2015 Share #2 Posted July 25, 2015 (edited) No optical differences with later model with the "right" hood... the other significant mechanical difference is the filter size (E49 vs. E55 for later items) : also,they have the s/n on barrel' side... an odd placement tyipical of some lenses of that times It is not rare... there is a batch of 3000 (2.947.201-2.950.200) and some also previous to this (I have 2.814.779 and other do exist with 2.8xx.xxx) Edited July 25, 2015 by luigi bertolotti Quote Link to post Share on other sites More sharing options...
