Is it just me, or does it seem like used crop lens prices are dropping like crazy lately?
- The only 15-85's that have sold lately are those listed at $450 or less.
- Sigma 17-50 OS is going for like $350 on ebay and that was hard to find under $600 last year.
- Tamron 17-50's are now more like $250 and the VC version ($600 new) at $300-325.
- Canon 17-55 are under $600 easy.
- 18-135 STM now sells for way under $300, was almost $500 last year.
- I think the 10-18 from Canon killed the value of any crop UWAs. Sigma 10-20s are going for $300, Tokina 11-16's for under $400, 10-22's have never been this cheap.
- Sigma 30mm's are like $250-300 used now.
- 55-250's are hard to sell even at $100.
I'd be really wary of investing a lot of money in new crop lenses. Seems like L lenses and other good FF lenses still hold their value as well as ever (except the 24-105L)
And crop camera bodies devaluation seems even worse...
