But, I'll probably come to my senses soon and go back to the F4 lenses. Maybe I need therapy.
Try to wait, if this is possible. I do that too. Inam hoping for a small and light Sigma travel telezoom. But I wait already a long time for that kind of telezoom...

I guess it's a good thing the Leica 24-90 & 90-280 are so ridiculously expensive.
Yes, and on top of the insane price, the 24-90 is heavy too.
