I have oft thought that M43 just isn't really a true competitor for the DSLR ...I still think this. I bought the GX1 for general photogaphy and maybe a bit of street photography if I can summon the courage to go for street. Yesterday I decided to take it Urban exploring ...after 3 shots I asked my friend for the keys to his car, took the Panny back and grabbed my Canon 500D. I was in a chapel - all windows metal sheeted and very, very little light coming in. Took a shot with some light painting with a torch - 20 second exposure. How long did it take to write the shot to card ? ...errr 20 seconds what now ? 20 seconds !!!! I guess I wont be using the GX1 for long exposure shots again - leave it at home when out Urban Exploring . Is this common to M43 cameras ?
