Having walked the road uphill from P&S to advanced compact, to finally find a good system in micro43, I thought I may share my experiences with others and maybe save them some time and money (if others confirm my thinking is on the right path!) I do not speak as a pro of any kind, I use the pictures I take for family albums, to document my work in the orchards, and for fun. I do enjoy the process of taking and postprocessing pictures, and am starting to develop an unhealthy interest in printing... Anyway, I upgraded to :43: from an LX5, with just a bit of technical knowledge, and got a "kit" lens to go with my camera. I thought it would give me the additional quality over the LX5 that I found I wanted. It was so, on a nice summer day. Winter come, and taking pictures of my small daughter inside proved to be very difficult, as it was to get good macro shots with just a close up add-on lens. After I managed to fund them, I got two primes to cover the above needs - the Panasonic 25 and the 45. Oh boy, was I in for a surprise! The basic quality image gap was similar to scuba diving with swimming glasses or a proper mask! And the rendering of the pictures, the mood and the way colours look, not really comparable! If before the good primes a technically good picture (to me) left me a bit cold, the looks of a properly nailed pic with the 45 gives a dreamy, etheric rendering I could not imagine before. The 25 on the other side, allows me to have pictures taken in less than ideal conditions, speaking of available light. However, it is much harder to obtain a beautiful (to me, again) picture in good light with this lens. For some reason unknown to me, generally the results are a bit too clinical, however it gives its best renderings of reality in shaded places, at nights, indoors. The point I was trying to make, is that better lenses (for the purposes I need most) make the process of taking pics, and the results, much more pleasant. Before one shells out a lot of money on new bodies, bigger sensors, maybe it would be worth to think a bit about the most used focals, and get a good lens. And most important of all, try them (if possible) to see the emotions they are able to imprint in the scene, as this is the biggest gain I noticed, after getting used to the improved overall quality.
