Al Brown Posted December 29, 2021 Share #21 Posted December 29, 2021 Advertisement (gone after registration) I have described my brand new Summarit 75 decentering issue in another thread. A dealer in Austria showed me a BRAND NEW Summilux 0.95 a month ago which he cannot sell as "brand new" because it has so much dust in it. He fired up his strong LED through the lens and boy it was something you would not expect from a brand new 10K Summilux. I have no problem with the odd dust speck but this one was quite... dusty.

If it has not happened to you or anyone you know it does not mean it doesn't exist. Even if you have a dozen brand new lenses your count is statistically not relevant to the million(s) of Leica lenses out there. There are BOUND to be lemons among them and that is a hard fact.

I would be interested to hear what conversation your dealer had with Leica. He should have rejected the lens. Incidentally, I presume you meant to write Noctilux, not Summilux for an f/0.95 lens? 1 Quote Link to post Share on other sites More sharing options...

Thank you for the notice!@wda I have found a blog on the dealer's page where somebody (not me) shows the dust of this very lens.https://www.jogeier.com/blog/let-s-talk-about-dust-christian-doffing/ Have seen this very lens (and the dust within) with my own eyes while visiting there, before this blogpost was made.

I still think the dealer should have spoken to Leica about this matter. Quote Link to post Share on other sites More sharing options...
RayD28 Posted December 29, 2021 Share #27 Posted December 29, 2021 Advertisement (gone after registration) The problems that Alan noted in his original post are obvious things that could be detected right out of the box. For those of us that have no dealers nearby, is it possible to pay the dealer for the new lens and ask them to inspect the lens before shipping? If the dealers discovers a defect they can then can void the sale and then sell you a different lens and go through the same process until you get the lens you expect. I suppose a dealer might hesitate doing this because it might turn some "new" lenses into "open box". In my opinion that should be between the dealer and Leica. If the dealer sells the defective lens as open-box then I would hope they disclose it in the description. Buying anything new and discovering a defect and the retailer saying to work it out with the manufacturer is to me unacceptable. 2 Quote Link to post Share on other sites More sharing options...

jplomley Posted December 29, 2021 Share #29 Posted December 29, 2021 On my second M10M with a line down the centre and waffle pattern in the shadows when levelling an image. Absolute crap QC. Quote Link to post Share on other sites More sharing options...
250swb Posted December 29, 2021 Share #30 Posted December 29, 2021 I accept that the OP could have had a genuine problem with a lens, but from the photos shown it's predominantly more like a problem of some cleaning fluid that hasn't been polished off, a typical smear ready to be buffed with a lens cloth. It may have been left by a dealer thinking to make the lens perfect from transit dust, but we all have our own levels of perfection, some of which are absurd in the extreme. Not sure where faults with an M10M come into it, unless this is now a general bitching about Leica thread. 1 Quote Link to post Share on other sites More sharing options...

I was just amazed over the OP’s bad luck. I never had any problems with new Leica lenses but had a few dud bodies including a new M8 that broke the first week, early R8 that was incompatible with the motor drive, DMR back that froze every few hours. And of course the corrosion crap. But they were less QC issue than design flaws. Edited December 29, 2021 by rtai Quote Link to post Share on other sites More sharing options...
cboy Posted December 29, 2021 Share #32 Posted December 29, 2021 Probably the easiest way to ensure you don't get a dud is to go a brick & mortar store and upon purchase ask them to open it in front of you to inspect it. Quote Link to post Share on other sites More sharing options...

Only the last one (50 lux) could potentially be cleaning fluid left on the lens, I didn’t bother cleaning the lens because I’m disappointed to see the lens arriving in this condition nonetheless, and I want to return the lens in its original condition, but with regarding to all other examples in the photos, I’ve tried to clean all of them, they are indeed coating scratches. Unless coating scratches is normal to be found on a brand new Leica lens, then I guess I’m asking too much. 1 Quote Link to post Share on other sites More sharing options...

Well you are either the unluckiest person to buy Leica lenses or the least able, one or the other. Quote Link to post Share on other sites More sharing options...
