I have a decision to make and I'm having trouble getting good advice. I bought a brand new AF-S NIKKOR18-35mm f/3.5-4.5G ED lens a few months ago ($750 new) but was just given a damaged AF-S Zoom-Nikkor 17-35mm f/2.8D IF-ED for free ($2,000 new). In perfect condition, obviously the second is the better lens, and since they two lenses serve basically the same function for me, I'm trying to decide which to keep and which to sell.
The 17-35mm lens was given to me used. It's about 8 years old and sat unused for the last five. It seems to be a good lens without sicking, major scratches, or mildew. I've done some shooting with it and from what I can tell it produces good, clear photos. As far as I can tell, the only problem is that the autofocus motor is out, which is a common problem with this lens as it ages. To repair the lens to factory specifications can cost anywhere between $300 and $600 dollars from what I can gather.
The 18-35mm cheaper lens is in perfect like-new condition. And if it helps, I do a lot of landscape and travel photography and I'm shooting with the D800.
What should I do?
1. Repair the used one and sell the new one.
2. Repair the used one and sell it.
3. Sell the used one without repairing it and keep my new one.
Thanks for the help!
