Not long ago I bought pany 14-42 to go with my GF2. Now there is a guy that sells the 14-45 for what I can get for the 14-42 + 40 euro on top. I am wondering if all the trouble to make the switch is worth it: - i need to travel 2 hours to his place in each direction - need to post my 14-42 for sale, deal with potential customers etc, which is always a hassle - my 14-42 is basically new, while the 14-45 might be few years old - i am not sure in the end it is worth it From everything I read I am almost sure I won't be noticing visible difference between the two - I am not a pixel peeper and as I am still a beginner there is a high chance that my pics will have other more pressing issues than the small IQ difference between the two lenses. I think I even consider it just for the warm fuzzy feeling of having "the best kit lens". The build quality and the IS switch are nice to have too as I plan my next body to be Olympus... So, would you make the change if you were in my place?
