Lack of IS is not something you get on UWA, there are no UWA lenses with IS. Most likely (there was recent thread) because IS will not be very effective at such short focal lengths - you can hand hold these lenses with 1/10 or so. IS works best on longer focal lengths.I saw that lens and was attracted to it's 10mm view, but I did not like it's lack of IS. I figured I could lose the 5mm and gain the IS on the 15-85mm lens or lose 7mm on the 17-40mm and gain the L lens. I was seduced by the red ringyou want wider...any reason you're not considering the 10-22? I'm a big fan of the 17-40, but 10-22 will get as wide as you'd ever want.![]()
Therefore, lack of IS is not a factor to decide against an UWA.
10-22 or 15-85 are just two very different focal ranges, and that is what has to guide your decision.
So, you could think:
10-22 and 28-135 as your setup or
15-85 and 55-250 (or 70-200, depending on how much you want to spend) as your setup (and selling the 28-135)
