Originally posted by huskybusky thanks for all the tips guys..I'm reading it all and taking it all in before i ask any more silly questions.
For the guy that asked which countries im visiting..well i have around 20 days and i'm thinking 5 days each country between france/spain/italy/england.
My first time to Europe and going in apparently the worst winter in a while but i know I'll have fun.
If anybody feels like contributing any more it is helping me so much i promise and thanks to everyone so far I'll hope to pass on whatever i learn here someday .
Oh and don't get me wrong I'm happy to buy another lens for the price i set($200-300)..money isn't the HUGE issue, normally I'd spend more but just the damn return tickets cost me $3000 so I'm not in excess of hobby money right now.
So yeah any lens that can and will help me at that price range I'm more than happy to purchase and in the meantime I'll be spending quality time with my camera and manual learning the ins and outs.
I personally myself didn't want to buy a high end P&S either but i thought of that as an option as i'd heard people raving about the LX3 and such and also it'd keep me away from asking so much help from random strangers. Like who am i to take up your time and i really do appreciate every post thus far.
Personally, I agree with the posters who have said that the wide end is great in cities, though the options at that end aren't really in your price range.
However, since what you have noticed so far is that the detail for buildings has been too small, I think we need to meet you where you are. A wide lens (like a 10-20 or 12-24) only gives you the chance to make things even smaller . . .
Now, the first thing I have to ask is: are you shooting jpeg or raw? Are you looking at pictures on computer, magnifying and cropping? Because even with a 10MP image there is a considerable opportunity to isolate the interesting parts of your picture in post-processing, even when you couldn't do that when you took the picture (because of your lens, distance from your subject, and so on). If you shoot in raw (or raw + jpeg) you have the opportunity to do quite a bit with your picture after you take it, and you will not have lost any detail to jpeg compression.
On the other hand, if you are relying a lot on what the pictures look like in the rear lcd, well, the rear lcd on the K200D is not all that good, and even at max magnification in it may be difficult to tell whether the detail in your picture is something you can use. Which is another reason to rely on post-processing instead.
My one other comment would be that, if you really do want to zoom in with a lens, buying something like the Tamron or Sigma 18-200 might be the best idea. Quality is not necessarily as good as the 18-55 (version II), but I doubt you would notice the difference, and the convenience of zooming without changing the lens can be a big deal. And those lenses are definitely in your budget, which the new Pentax 18-135 WR or the Sigma 18-125 may not be.
When I was a DSLR beginner, my first trip was to South America. I got on mostly with the 18-55, but I remember going to a nature preserve and being frustrated by constantly switching out at 50mm to a telephoto zoom, then back again. It seems to me that you have enough to learn right now that the additional decision to switch lenses is more complexity than you need. For the same reason, I am not sure that a prime lens would be a good choice for you for this trip. I love prime lenses, and if I were headed to Europe right now I might take only a DA 15 and a DA 35, with maybe a 70 or 85 if I could afford one. But once again, I think prime shooting is more complexity than it's worth for you right now.
If you learn to compose the pictures you want, use ISO 800 or even 1600 at times so that your pictures don't come out too dark, and deal with basic issues of cropping and de-noising in post-production, I think you will be able to let go of your anxiety and enjoy your pictures from your trip. Then after that you can look at prime shooting, artistic depth of field effects, and start to obsess over image quality issues . . .
