I guess this is what I get buying from ebay and trusting seller's description and then getting sidetracked and not doing good testing for a few weeks after receiving the lens.. anyways learning experience aside should I send this lens to canon and pay for it to be calibrated? Here's a classic example of what the softness looks like, though if you need more examples I can provide them... the right side of the image will be very sharp, but it fades to a blurry mess on the left side of the image more then one would expect for a lens this price. I don't mind sucking it up and sending it in, just curious to get some thoughts.

Edit:

here's a few examples.. I don't have the RAWS for these but these JPGS are plenty high quality to show it.

The road picture shows it is possible to get sharp pictures from the left side, usually on the foreground is when I can get it sharp but then the foreground on the right side will be soft.. perhaps lens decentering?

Yikes !! Look's like some serious decentering going on. If the seller never enlaarged or used editing softwarw, he/she might not have noticed. Look's like a trip to Canon is in order. You are not by anychance using a cheap filter on it are you?

Woah, if those shots are just with the naked lens (without any filters) then something funky is definitely going on on the left side, especially left center. That doesn't happen on my 15-85. GregoryF is right though, it's easy to overlook without zooming in very close digitally. Nonetheless, it would bother me if it were my lens and I'm guessing it's concerning you too since you made this post. I say send it in to Canon.

How much does it cost to calibrate a lens by Canon anyway? I've never done it before.

If the lens is decentered, this means that the elements are out of alignment. This is fixable, but not an easy fix.

Mine doesn't do that. I don't buy anything costing over $10 on Ebay anymore, it's really turned into a ripoff paradise.

Yup, major, major decentration of the entire left side of all those images. OP has so elements out of alignment in there. It's likely this lens has taken some HARD hits, or it wasn't packed well in the shipping box.

When did you buy the lens? If it was less than 45 days ago, you're well within your right to return it for the FULL value you paid, shipping included. It's ebay/paypal policy, even if they say they won't accept returns. If it was over 45 days ago but less than 90, file a credit card chargeback, and send it back, tracked/insured. You'll win your chargeback.

You can send it in, but that would be silly. If the seller claims that shipping damage caused the decentering, he can take it back and file insurance claims on his own. Sending it in for calibration without being under warranty... you're looking at a $200-$300 charge right there.

Yep, pretty bad and not to be expected.

It was exactly 60 days ago. I know it wasn't done on my end as I have never dropped it and some of the earliest pictures do have the issue. I don't feel 'good' about going the chargeback route after all that time as I should have done my DD to make sure the lens was good from the start and not have gotten sidetracked and waited for the weather I wanted then just started using it. hmm....

Canon quoted $145 for out of warranty repair on the website, but you think they will likely ask for more when they get the lens in the mail and inspect it?

They can easily ask for more. Canon Repairs is pretty well known for sending revised estimates. I would IMMEDIATELY ask the seller for a return, and if he refuses, follow up with a chargeback. 60 days isn't too late for the seller to file insurance claims. The longer you drag your feet and play around with quotes, the more trouble it causes. If you know it wasn't your fault, what's the problem? You waited too long--so what? The seller sent you junk and expects you to pay for those hidden problems!! Send it back. CC protection is there for a reason.

I feel differently about it. If I was the seller (assuming he/she thought the lens was fine) and had to deal with stuff 60 days later I would be very unhappy about it. 60 days to check that a lens isn't a dud? That's crazy IMO.

Plus the seller would have to find the money to repay it. Not always easy if he doesn't have a lot.

Personally i would contact the seller and get him to pay half of whatever it costs to put the lens right.

I agree that he shouldn't have sold it without mentioning the defect but i do think 60 days is more than enough time to check the lens over, especially as this is very obvious.

Good luck dissident.

I would try that if the seller refuses to accept the lens back

I agree, best you could do IMO is ask for half the repair and explain why it took you so long to check the condition of the lens. Over sixty days is a bit much to contact them and say hey, its broken. If it were me, I wouldn't believe it and would of wanted contact sooner on the issue.

Good luck though repairing the lens! Maybe they will accept it back, who knows!
