Compared to the 18-55mm? Yes.
The kit lens is best at around 35mm, f7,1, yes, but the 40mm will still outshine it in every respect. The Pentax kit lens is better than the kit lenses some other brands offer, but its still a kit lens. I like it because it is versatile and light, and if you have the WR one, it can be great in bad weather (better to have a WR kit lens than no WR lens at all). But if you want optimal quality, the limiteds or * series are your best friends
