Wide Angle for Crop and FF?

Are you sure the resell value of 10-22mm is good? I had posted my 6 months 10-22mm on CL for two weeks and asking for 650 in bay area. No one offered more than 600 for it. In the last, I had to compromise the price 600 USD. 6 month lens for only about 75% resell value.

Well, there are multiple mistakes here. One, using Craigslist and being surprised that people low-balled you. If you're selling expensive photo equipment, go to a photography forum to sell it. You'd have probably gotten $650 pretty quickly from FredMiranda or POTN. This also makes the point, buy the 10-22 used from someone in mint condition, you'll save some money (say 10% off retail), and when you resell it, you'll have not lost that initial retail price.

Every lens, no matter what, is gonna lose 5-10% when its no longer brand new in the box. Only if the demand gets really high (24-70 for example) will a used lens sell higher than new. But, if the trade off of spending the extra $100 in this case is that you get a useful focal length for 2 years before upgrading, it's well worth the money

Have you considered saving your money and just renting the lens as you need it? Instead of spending money only to have to resell it soon. It may be a little annoying not having it on you 24/7 but if you are thinking of upgrading soon anyways it may save you money.

No one has really mentioned the 8-15L.... Works on both, and if you get DxO software, or are good with photoshop, you turn the the fisheye images into rectilinear images fairly easily with good results...

Don't laugh, I'm just using this page and images as reference...

Sigma 12-24 or samyang 14. I have the samyang on my wishlist.
