I tested out the sigma 10 - 20, f4 - f5.6 briefly, seemed pretty nice but i was put off by its slow speed

- all my lens lust lenses are f2.8 or better :P

pentax have a 10-20 f3.5 - f4.5 so ill need to check that out. But from what i've seen the sigma has been getting good reviews.


Im going to do a little round up of all the options for myself and ill post what i find here...
