I'm rather disappointed by the performance of this lens. Especially, the amount of distortion and vignetting, I think it sets a record in itself!
I find it surprising that the lens is not really smaller or lighter than the Pentax DA 18-250 (or equivalent Tamron) which is an APS-C lens and a 13x zoom instead of 10x. Same thing about IQ, it seems the Pentax/Tamron is better in most regards too.
