Subject: Re: [Leica] Weight of the 90 Summicrons
From: John Collier <jbcollier@shaw.ca>
Date: Wed, 22 Jan 2003 07:37:22 -0700

90/4 4 element 11130 295g
90/4 collapsible 11631 340g
90/4 3 element 111830 305g
90/4 Elmar-C 11540 270g
90/2.8 11129 320g
90/2.8 T-E fat 11800 355g
90/2.8 T-E slim 11800 225g
90/2.8 E-M current 11807/11808 410g/560g
90/2 first 11127 685g (I do not know if that weight includes the hood)
90/2 second 11023/11123/11122 685g (lots of variation in design so I 
imagine the weight fluctuated too)
90/2 third 11136/11137 410g (chrome should be heavier)
90/2 AA 1884 500g (heavier chrome version now available)

All weights from Sartorious: not always the most accurate but 
everything should be in the ball park
