DOF at long ranges ??

nureality wrote in post #10246990
This may sound out-of-left field (sorry that pun was too easy), but was the lens's focus limiter set to 1.2m-infinity instead of 3m-infinity? The reason this can be relevant is because if its set to 1.2m-infinity it has a longer range of travel to lock focus and for AI Focus that can cause much longer focus lock time.

As for the Canon UV filter, the Canon filters are rebadged Tiffens (or worse) and are just junk. Take that thing and toss it IMMEDIATELY.

Have you even read the thread?

The points you raised have been raised several times and all proven not to be the cause.

I just read the entire thread, and I'd just like to give the OP props for listening to some solid suggestions, and posting samples with brief exif. Taking the time to do controlled samples really helped pinpoint the issue. Thumbs up!

Props also to those who read, listened and suggested, all the while staying up-to-date with the thread. Outstanding job!

Not bad for repairs, but i'm thinking you could have bought a new one for what you're going to have in it.

I wanna know where you can buy a 70-200 f/4L for $119, I'd buy 100 on the spot.

pretty sure he means (cost of used lens) + $119 = ~(cost of new lens)


now that it's fixed hopefully i wonder if you'll be able to see the difference between filter on and filter off...

Yes, will try that for sure and post results. Will see once and for all if the Canon UV filter really is junk as most people claim.

A very large THANK YOU to all of you for your support and encouragement in getting this issue resolved. Stay tuned though, I will post some shots hopefully by tomorrow or Friday the latest.

For the record, the cost of the used lens + the repair was still $130 less than the cost of a new lens at B&H. Of course this does not include the fact that there is an $80 instant rebate on the lens at the current time. I wish there was a way to tell if a rebate is on the horizon. I would have probably waited and snatched a new one if I new a rebate was coming.

Ready for a happy ending?

Before I sent the lens to Canon I contacted the seller in an attempt to return it. I did not get a response for two days so in the mean time I started to lose patience and decided to send it off to Canon. When I finally did get his response he said it would not be fair for me to return it (especially since it was not working right) given the fact that it was three weeks since I left him positive feedback. I totally understood this and did not pursue the issue any further at that point.

After I got the lens back and read Canon's description of the problem and resolution, I contacted the seller again in an attempt to convince him that there was no way I could have damaged the lens. I explained to him the truth... which was that when I first got it, I took a few test shots of my dog, boxed it back up and put it on my bookcase waiting for an opportunity to really use it. Three weeks later I finally got the chance when my son had baseball practice. As you all know, that's when I first observed the problem. So the odds of the damage being my fault was pretty much next to zero. It seems likely the case that it was damaged during shipping because the seller sincerely claimed that he tested it thoroughly at all ranges and all apertures.

Well, guess what...the seller just issued me a refund to compensate me for the repair (and then some for my troubles) without even requesting the receipt that I offered to email him. In response I expressed to him my gratitude for his professionalism in resolving this matter in a very favorable way. As it turns out, I think he was a pro.

A happy ending indeed!

Now for those test shots I promised....maybe tomorrow??

Great to hear everything worked out!! Kudos to your eBay seller, he's a top-notch guy!
Looking forward to seeing those test shots

Looks like it worked out for you . But after 3 weeks, I think you would have been on your own !

I'm glad to hear it all worked out for you.
Did you have the lens insured when shipping it? I wonder if the post office could compensate the seller now?

Any luck with those test shots?

Or are you still recovering from eye injuries caused by the sharpness of your lens?

It never ceases to amaze me what Canon came up with in this lens. Those are some very nice shots, and I am quite pleased that you now have the lens you thought you bought to begin with.

They look great (as expected)!

Hope they restored your faith in L lenses.

Sorry you are not getting the same jubilee most others get to experience when they "discover" what L lenses are all about for the first time. However, don't despair. This will only make the experience more intense when you get a properly working L lens.
