da 40mm ltd vs kit lens

i recently taped my kit lens at 40mm and have been using it like that for a while now. Of all the focal lengths it covers, even with it not taped, I think that i use it most at 40. When I want it wider I change to my 10-20 or longer I go for the 70-200.
if I were to get a new body- maybe the one that is rumoured to go between the k7 and kx, do you think that I would notice a large improvement in quality from the kit lens to if I got a da 40 ltd? The main attraction would be the size of it, and it being much easier to carry around. But also the extra speed. Would I notice a difference in sharpness?
Does anyone have comparison photos? My kit lens is the 18-55, not WR or II or anything

Simple answer is a resounding yes.
I don't have comparison photos to provide you but you can see the loads of DA 40 photos on this forum for yourself to see what it has produced.

The kit lens and DA 40 are leagues apart. There is more than a stop of difference in maximum aperture between them. Then there's the image quality - sharpness, contrast, control of vignetting and CA, AF speed, you name it, DA 40 outdoes the kit lens. Have a look at photozone's data if you're looking for quantitative proof, but you'll be impressed with the DA 40.

The DA 40 is an amazing lens. Really fast focusing. Corner to corner sharpness and at 40 mm it is about a couple of stops faster than the kit lens. The kit lens really should be stopped down a little to get good sharpness, whereas you can comfortably shoot the DA 40 mm wide open. To me, the only question about recommending the DA 40mm to someone is the focal length. For some it is too long and others it is too short, but since it works for you, get it!

If you are routinely shooting at 40mm, the DA 40mm is the lens for you. Superb in every aspect

The kit lens is far superior to the DA 40.

But only in the focal range of 18-39mm and 41-55mm.

At 40mm, the DA 40 creams the kit lens.

Also, the 40mm is the cheapest of the ltd lenses. Its a great introduction to the magicthat is pentax ltd primes. Plus it lowers the profile of the camera to the point where it's almost coat pocketable.

And now for a contratian view, 'cause that's how I am.

Consider a manual M42 Mir-1 37/2.8. Good optics, and you can get one for US$50-70 or so.

But the 40ltd will enrich Pentax and keep Hoya happy.

The DA 40 was the second new lens I bought after the kit lens. I essentially never used the kit lens again.

I had the DA 40 and still have the DA*16-50. I'd have to say the DA 40 bests that zoom for sharpness at all apertures as well. Sharp right from 2.8, a razor by 5.6.

I've barely used my Sigma 17-70 since I got my DA40. The DA40 just stella. The 17-70 is emergency use only now, and once my DA21 arrives I don' think I'll ever use it again.

This was the first DA 40 thread I could find, is there a DA 40 club on this forum? I went looking and surprisingly came up with nothing
