Hey All
LBA has hit me again but not for a certain lens but a type of lens.
I currently have the 16-50 to do most of my wide angle but wanting a little more. So i'm stuck on two options (atleast the only ones that I know of)
Pentax 12-24 or the Sigma 10-20
So a few questions
1) Is the difference between 12 and 16 enough to justify buying the 12-24mm
2) Is the Sigma also a cropped lens that will not work as well with a FF?
3) How big are these lenses?
4) Is there any other lenses coming in soon that may be a better choice than either?
