The seller sent me these two photos taken from a Canon D30. I asked him to take a photo at 70mm and 200mm f2.8. Could you guys tell me whether this is a good copy of the lens? This way, I can decide better whether or not to buy the lens from the seller? Here are the two images:

Geez, could he have chosen a worse subject for the 200mm shot? From what I can make out of it, it looks pretty good.

There seems to be a lot of CA at 70mm, at least for a lens marked APO. It's pretty obvious where the light reflects off the chrome of the things you turn to tune the guitar.

I'm no photography expert, but I noticed that immediately as well. I'm hoping to see a few more opinions on the lens. Thanks G35GUY!

I don't know it's awfully good for a shot @ 1/13s (at least the guitar is handheld)

As to CA isn't this of a secondary reflection? Look carefully @ the white areas on the tuning knobs have no CA directly, but only on the reflection of the secondary neon tube... and on curve surfaces :O
It would be interesting to see how other lenses behave under the same circumstances :idea:

Ok. I received a few more photos of the lens and from the lens. Unfortunately, these are cropped images and don't have full EXIF. I'd hate to ask for the full images...the seller might get ticked off. :roll:

Photos of the lens...looks clean to me.

there is quite a bit of motion blur in the first, so its really impossible to judge from them.. the second picutures he took are a rather bad subject and pretty useless as well...

but the lens looks clean, i would not be too worried...

and i think that most lenses are "sharp copies".. alot of the so called softness issues people have with this and many other lenses comes from photographer error.. or from slight front or back focusing.. which can be easily corrected with a little calibration.. there are targets online to check for front/back focusing if you get the lens and think this is occurring..

but i reiterate, my guess is everything is fine and i would not be overly worried..

Ok...Ipurchased the lens. I got it thru ebay from the seller that sent me the photos for about $570 shipped. I think it's not too bad price-wise...considering the condition of the lens itself.

Now I need to find a way to pay for it! :G I guess I'll sell my Canon 75-300 IS USM lens since I'll have too much overlap.

once you use that 70-200 2.8, you won't want to use the 75-300 again anyways...

yeah, this lens will seriously outclass any Canon 75-300 lens, they're all pretty mediocre.
