As my sig states, my current lenses are the Canon 18-200mm and the 300mm f4l.
On the long end I am set and pleased. However I want to go wider as well.
Since I only recently got the Canon 300mm f4l, I don't yet have the fund to purchase a Sigma 10-20mm. I've been thinking of selling the 18-200mm but the versatility is just a shame to loose.
Therefore I thought maybe the 15-85mm could be a good replacement for my 18-200mm.
It's sharper, wider, better overall but I loose the long tele-end and of course it is not as wide as a 10-20mm lens.
Is there any point replacing the 18-200mm to a 15-85mm lens or should I wait and save up some money and just add the Sigma 10-20mm to my collection in the future?
