what are the silver 35 summicron asph lenses made of?

Mine is made of brass. All bright chrome and black paint lenses are made of brass, all black chrome lenses are made of lightmetal alloy. There is a considerable weight difference.

Sorry, I meant the 28 summicron asph silver?

 

The summicron 28 is the only silver lens made with aluminium as far as I know.

I have a silver 28 cron, and it weights the same as the black anodized version.

Other silver lenses on the current production such as the 50lux asph or 35cron asph are made with brass.

Your's would be a 'special' then Jaap. :D

 

The later 28mm f2 silver lenses were aluminium.

It would be too, were I not responding to the number 35 :D I guess the 28 would be too heavy in brass;)

Just out of curiosity, are Leica lens made of mainly brass or aluminum? (anything else?)

 

If there's more, which material is the lightest?? (Does it mean it is less durable as well?)

 

I've always been curious about the "black anodized" version... Does it mean better or worse? Heavier?:confused:

Brass and/or aluminium, depending on models/versions (see above): aluminium is always lighter, and not less durable than brass... usually, aluminium surfaces have a "way to be scratched" that makes them more delicate in this sense... but is a personal taste.

Anodizinig is a process to make a surface black without using paint... it doesn't have impact on weight: a black anodized surface is much more resistant to wear then a black painted one: there were some old Leitz lenses that used to be black painted, and often the brass under the paint is well visible after years of use... but they are rare and often much valued... ;)

Ah, it's good to know :) Thanks!

I think there might even be some glass in there! :D

 

AFAIK, the stuff they make these lenses from is heavier than 'normal' glass. Mine feels like lead!

Yes, I CONFIRM that there is ALSO some glass in lenses.... :p, you can trust my assertion.

 

Glass weight is a question that sometimes has intrigued me too... pity that, afaik, the weight of the glass only hasn't ever been detailed separately... there are some lenses in which I think its role is really "weighting": if one thinks that the rather little 28 2,8 asph has 8 glass elements... the first Elmarit 28 had 9 (it was rather bulky, indeed)... the first Summicron 35 (compact and "light") had 8... I have the rare 180 2,8 for Visoflex: it has a terrible weight, I think due also to the fact that its optical design (1 - 3 - 1 "Olympia Sonnar-style") has for central element a massive "cylinder" of solid glass (about 6cm diameter - 5 cm length)
