Hi, I have a 24-105mm lens that I bought in 2008 used. Based on the serial code, it was made in 2007. I have been using it with my canon XSi for 5 years in the hope that I would eventually upgrade to full frame.
That day finally arrived and I just bought a 6d! Thing is, i bought the bundle so i have another 24-105 mm lens that is brand new.
I am going to sell one of them but should I keep the 2007 one or the 2013 one?
My old 2007 lens has no scratches and I don't think it has much dust. It does have quite a bit of zoom creep though, so that when I point it down, gravity pulls the front element down, zooming in. Is that cheap to fix?
I figure selling the new one on eBay will net me about $125 more compared to the old one.
Here are some other possible factors: Has there been any general improvement in Canon's manufacturing quality over time? Have they improved the coatings or glass elements but kept the same model number? Do the coatings degrade over time? Should mechanical wear and tear be a concern?
Thanks very much in advance!
