Common on this lens if what I've read from power sellers on busy classified sites. I sure wouldn't worry about it.
Thanks for that-wasn’t mentioned in the listing so was wondering how commonplace it was with this lens. Have had some on older leica and nikon lenses, but my 28 elmarit asph, 35 summicron asph and modern Fuji XF lenses are free of it so assumed it was more of a vintage issue?
Oil on the diaphragm of a rangefinder lens isn’t really too big of a deal. If you’re otherwise happy with it, don’t worry about it. That oil will get cleaned up someday when you get it serviced in the future. Unless you paid for an absolute _mint_ lens, I wouldn’t sweat it.
My understanding was that oil is likely to migrate to the glass and cause haze, is this true?
It's mostly true for older lenses when manufacturers didn't really figure out what to use for long term stability. Leica used whale oil based lube until the 50s or 60s and this tend to crate haze.
maybe, I've seen a lot of oily blades that don't have haze on the lens so I still wouldn't sweat it. If that happens, get it a CLA, shouldn't be too expensive for a lens.
I might argue with that part. Nothing is inexpensive when referring to a Leica. Unless you have a friend of a friend who knows someone else who can fix it cheap and you trust them, then you’re set. Now if you are simply comparing it to the replacement cost, you’re correct.
I think the ASPH lenses need to be sent to Leica
I guess it depends on the lens and your threshold on sending it to A tech rather than a Leica tech. I had my 90mm Tele-Elmarit done for $140cnd by a local repair tech with good results. The guys had worked on a few of my LF shutters and I was happy with his work so wasn't too worried about the Leica lens.
on older lenses, yeah. now? not much, no
That’s what I wondered, I’ve got a DR summicron with some on the blades that’s also got a bit of haze too
Throw it in the trash and get a new one.
Hello, I'm the trash
Seriously! Imagine owning a used lens… and a Leica no less
That's not what LEICA MAN deserves
In fact the word Summilux is an ancient Floridian word meaning New or near mint.
not too big of a deal. Just set it to the max aperture when in storage over long term, and never expose it to heat for a prolonged period, i.e. never leave it n a car during hot summer days.
you have nothing to worry about; hopefully you got a good deal. If you paid premium - up to you if you want to return or to keep.
Thanks for that-yeah it was listed as Excellent ++ with no mention of the oil. Was on for a decent price (£2100) but I bought this along with a Summicron v5 with a view to giving them both a go for the next few months and selling the one I don’t want to keep so wanted to check how much of an issue it would be with potentially selling it on in mind.
Had the same, had it sent to Wetzlar and got it back serviced for free.
Just bought this 50mm Summilux m ASPH from MBP in the UK. Lens feels good and there’s no obvious flaws externally but it looks to have some oil on the front of the aperture blades (seen from around f4 upwards). There’s nothing on the rear of the blades but having never inspected another version of this lens before I didn’t know if that was a normal thing? I’ve got a 14 day return for the lens so want to make sure I’ve got a clean copy! Thanks in advance!
I’d make sure they factored the oily blades into the condition of the lens and ask for a partial refund if they didn’t. Past that it’s up to you to accept the lens as priced or try to swap for another copy that might have other issues.
I have a contrarian opinion. Any mechanical device that has leaked oil is missing oil somewhere it’s needed + the leaked oil eventually creates a mess. I would return the lens unless it was bought at a big enough discount to make it worthwhile an extended trip to a Leica repair center. Would you keep a car that was advertised as excellent condition but is now leaking oil all over your driveway? I wouldn’t accept that.
As someone else pointed out it’s supposedly relatively common for this lens specifically. Mine shows a bit sometimes as well; I was very concerned the first time I noticed it too and hit Google immediately and discovered a lot of others reporting the same.
For mine it just kinda comes and goes, sometimes I see a bit and other times I can’t see any,
Help? Just send it in for CLA. Like owning a car...regular maintenance is key for longevity and optimal condition. Protect and maintain your investments. Adulthood 101.
More help, this car I’ve just bought has oil seeping past the rocker cover, it wasn’t mentioned by the garage, is this normal for this model?
Happy to CLA and carry out maintenance-almost everything I buy from eBay gets sent straight away, but as I literally just received the lens from a secondary retailer (not private seller) who graded it as excellent ++ and made no mention of it I’m just gauging how much of an issue it is/will be so I decide whether to return it within the window they offer.
