Originally posted by Mushroom_Toy I have a 50mm prime and two 135 primes which are fine for my everyday stuff along with the kit lense. Im pretty sure going from my 6mp to 14 is a pretty good upgrade.
Not to mention my body has some dust in it, it needs to be prof cleaned, and its got a good bit of actuations on it.
Using the kit lens on your K20D won't really reap any benefits though. The kit, to be honest, isn't that great of a lens resolution wise, contrast wise, distortion wise, in fact, it is the WORST lens in Pentax's current line up (also the cheapest). I really hate mine and I will try to get rid of it as soon as I get my 35mm f/2 and when I can afford a 12-24mm f/4.
But I digress. You should really save up a bit more and then buy a better lens to get the best out of your K20D. The Tamron 70-300mm f/4-5.6 is a full frame lens, but you don't see anyone using it on their 10MP 1D mark III.
