piero Posted November 26, 2008 Share #1 Posted November 26, 2008 Advertisement (gone after registration) besides the outside color, did anybody experience quality difference in assembly and/or performance of lenses? Link to post Share on other sites More sharing options...
Advertisement Posted November 26, 2008 Posted November 26, 2008 Hi piero, Take a look here Lenses: Silver Vs Balck finish . I'm sure you'll find what you were looking for!
jaapv Posted November 26, 2008 Share #2 Posted November 26, 2008 Chrome is heavier. That is all. Link to post Share on other sites More sharing options...

gfspencer Posted November 26, 2008 Share #4 Posted November 26, 2008 Black is more stealthy. Other than that (and weight) I don't think there is much difference. Link to post Share on other sites More sharing options...

wstotler Posted November 26, 2008 Share #7 Posted November 26, 2008 Advertisement (gone after registration) Difference in assembly/lens performance quality? Probably not. Apart from looks, IMO, the chrome versions have a *slightly* different feel to them when in use. I'm thinking this has to do with their extra weight.

piero Posted November 26, 2008 Author Share #8 Posted November 26, 2008 I have tested 3 35 Summicron Asph, two blacks one chrome. Chrome has much better contrast and resolution, focus ring is smooth and fermier than blacks. f-stop ring clicks in place with no hesitation. Weird.

jaapv Posted November 26, 2008 Share #10 Posted November 26, 2008 Th three of them new? There might be a small difference in focussing due to different materials, but the optical part is 100% identical. Link to post Share on other sites More sharing options...
piero Posted November 26, 2008 Author Share #11 Posted November 26, 2008 out of the box. not a small difference I have noticed, in terms of sharpness. I was wondering if the assembly is done by different people. Link to post Share on other sites More sharing options...
wlaidlaw Posted November 26, 2008 Share #12 Posted November 26, 2008 Brass is easier to machine to tight tolerances than aluminium alloy. Aluminium alloys tend to be slightly "sticky" to machine in comparison to brass, which is possibly the easiest to machine of all common alloys. An additional factor is that brass does not heat up to the same extent as aluminium alloy when being machined. I am guessing that the end result of this is that there may be less variation in the brass bodies used for chrome lenses than the alloy bodies used for the anodised black ones (black painted lenses may use brass bodies). If you search back through threads of about 18 months ago on the problems of back focus and focus shift on the 35 ASPH Summilux, I think you will find that the majority of complaints are on black lenses. A considerable number of owners of chrome versions of the same lens, including me, said how satisfied they were with the lens. When I spoke to someone at Solms earlier this year, they did say how difficult it was to get this particular lens 100% right. It might just be that the tiny tolerances involved, favour chrome/brass rather than anodised alloy for this lens. Reading the posts on this lens, made my mind up to go for the heavier chrome 35 Lux. I have not regretted that decision. Wilson Link to post Share on other sites More sharing options...

andybarton Posted November 26, 2008 Share #15 Posted November 26, 2008 out of the box.not a small difference I have noticed, in terms of sharpness. I was wondering if the assembly is done by different people. Could just be the difference between any two or three examples. Yours just happened to be one chrome, two black.

Besides this... I simply like chromes a lot more ... Link to post Share on other sites More sharing options...
