Deliberate1 Posted January 18, 2012 Share #1 Â Posted January 18, 2012 Advertisement (gone after registration) Friends, my new 50mm Summilux asph arrived yesterday. It is a silver beauty. Focusing is silky smooth and aperature ring clicks into place securely with no ring slop. But I find that the rectractable hood is difficult to deploy. I do not have the same issue with my 50mm Summicron M which I bought used. Is this something that will loosen with time, or would a bit of lubrication be in order. If so, suggestions for something that would not attract crud not damage the finish? I have to say that I am developing an eye for silver lenses on black bodies. Beautiful. But the mass of this lens on the M9 body makes the package feel like a very expensive brick. Obliged, David Link to post Share on other sites More sharing options...

jaapv Posted January 18, 2012 Share #2 Â Posted January 18, 2012 For mounts, Leica advises a VERY THIN layer of vaseline, and only when needed. I imagine a hood would be the same. However, I have not felt the need for lubrication of any sliding hood on dozens of lenses over decades, so basically I would advise against smearing anything on it. Maybe you are not used to it being a bajonet type hood lock? Link to post Share on other sites More sharing options...

I will just give it a bit of time to get adjusted to its new home. David Link to post Share on other sites More sharing options...
microview Posted January 18, 2012 Share #4 Â Posted January 18, 2012 I think you will get used to it. But let's be frank, the clunkiness of that hood is hard to excuse, even if it does its job! (I have the silver, a bought last summer.) Link to post Share on other sites More sharing options...
pico Posted January 19, 2012 Share #5 Â Posted January 19, 2012 For mounts, Leica advises a VERY THIN layer of vaseline, and only when needed. Â May I second Japp's recommendation and repeat what I've written before: "Never, ever use graphite dry lube" because like a nano-demon it will find its self into your lens and just plain ruin it.

Twist it back before trying to collapse it. Link to post Share on other sites More sharing options...
photoart Posted January 19, 2012 Share #7 Â Posted January 19, 2012 Advertisement (gone after registration) I have the same problem with the summilux 50asph (from 2010), the hood, it is very difficult to move forward and back. The problem is not the twistlock, something inhibits easy gliding. Link to post Share on other sites More sharing options...

Twist it back before trying to collapse it. Â I did notice that on closer inspection. Unlike my Summicron 50mm and Elmarit 90mm, the Lux has these little indentations that act as a track for the deployment of the hood. I was not aware that it twists to lock. Thanks for that.

jaapv Posted January 20, 2012 Share #10 Â Posted January 20, 2012 It is not typical, the hood of my 50 asph, whilst I would not describe it a smooth, moves and locks with a light touch. Link to post Share on other sites More sharing options...
IWC Doppel Posted January 20, 2012 Share #11 Â Posted January 20, 2012 I would chat to Leica, they were very helpful when I enquired about focus ring differences between lenses and they seemed to have no problems adjusting Lenses in warranty, even if they were within tolerance. Â Can you find somewhere to compare to another new lens ? Link to post Share on other sites More sharing options...
Paulus Posted January 20, 2012 Share #12 Â Posted January 20, 2012 Maybe it's not lubrication you need, but adjustment. Could it be that your lenshood is not perfectly round? It happened to me once with an non ED 2,8/180mm Nikkor lens Because it was a little " egg shaped " it would come free. Â My 50asph glides like ice.
