Originally posted by Cambo It's not 'limited' to the 21; all of the Limiteds, in the green band days (SMC, NOT HD) could do awesome starbursts; here's one from the 15:
The 15 is probably as good as the 21 for starbursts. It's one of the few Pentax lenses I have never tested. My understanding of it, and my use of other wide lenses, tells me it's not as easy to master as the 21, but is a very rewarding lens in itw own right.
Originally posted by csa Yes, I'm aware that the 15 especially has awesome starbursts; I had originally planned on it, before I decided the 21 might be better for my needs.
I believe it's easier to use and more versatile.
