Haze or Fungus??

[Michael2710]

I purchased a Schneider 305 mm G-Claron f9 and after receiving it and doing an inspection of the lens I have found either haze or fungus on the back element. I not to familiar with this as i have usually purchased new. Any info would be greatly appreciated. thanks

Looks like fungal growth starting, but is hard to tell from such a low resolution image.

Have you tried cleaning it?

If you paid a premium price for the lens, I would not touch it and return it for a refund.

If you got a reasonable deal, then I would try cleaning the exterior of the rear element with 50/50 mixture of ammonia and peroxide, followed by lens cleaner.

''Schneideritis'' I guess ...

Macfred, I think that's more applicable to where the glass meets the mount, but I can always be wrong... (I have been known to be wrong)

I neither see this as Schneideritis of any kind.
Yes, with such I think of dislamination from the edge. BUT there are photos of seemingly Schneideritis, starting at center, under vacuum thus.

Anyway, the OP's question is pure academic.
The artefact has a degree where image degradation seems likely and lens disassembly is appropriate.

Same with me ...

I have not tried cleaning it, i wanted to first figure out what I was dealing with. I paid $375 for the lens so not sure if that is a fair price or not. The seller described the item as in pristine condition. Would it be better to send it out for cleaning?

 

[Kino]

If the seller described that lens as "pristine", I personally would then assume they had not even looked at it and would be suspicious of any other claims as to the shutter function, etc. and so on.

$375 is about fair market value for a pristine lens of this type (according to current "sold" value on Ebay); this is not a pristine lens.

If it were me, I would just return it and try again somewhere else, but that is my personal opinion...

If the seller discribed it as "pristine" he's either a liar , blind or a fool .
The lens is clearly faulty , you paid for one the was "pristine" i.e in good condition .
Why would you then pay to get it repaired ?
Unless it's an oily deposit from your shutter that wipes off after you unscrew the lens unit , your better off without it .

Get it sent back and get your money back .
Then get another from a reputable seller .

I am currently trying to work with the seller, but he isn't being to responsive. Thanks

Send it back. To suggest this is a “pristine” lens is a gross deception. Just return it for a refund and avoid this seller.

Did you get it off eBay ?
If so escalate is asap to the resolution centre .
They will do a packaging note that includes tracking and return costs , one it's been received you get a full refund .
Then leave negative feedback to warn others .

I got a Minolta lens early last month that turned out to be mouldy , listed as used and the photos were a bit back lit which ( deliberately , I think ) hid this fact .
Seller tried giving me some BS so I escalated , sent back and got a full refund , no messing .

Where did you get it ?

If

Where did you get it ?

Yes EBay, communicating with seller now.

 

[neilt3]

Just to add , if it was off eBay , in the part for contacting the seller , select the option of " not as described / not as pictures " and it automatically starts from that date the returns process .
Saves you waiting , especially as they are being unhelpfull / rip off merchant's !

Bought elsewhere , contact your credit card issuer that you payed with stating that you have been defrauded out of money , as they insure against this and will refund you .
It's their problem then getting the money back off the seller .

I would open a refund/return ticket because sooner or later you will do it anyway.
