Just curious, but did you consider the D90? It would have saved you a complete change of systems.
Whatever the reason, it's good that you enjoy your new gear. Congratulations on the new equipment!
Wouldn't have made all that much diffrence tbh if i had gone with the D90
Mainly because i still be lugging about glass as i can never make my mind up what to take.
With the E-620, i get a body that much smaller & lighter than the D90
I've got a smaller selection of glass that is both very good quality & again light.
as i can fit all my gear into the crumpler for just day walks.
Plus i got plenty money left over still from when i sold the D300 kit, so that a bonus.
It's like i said in my OP, i have no regretts at all going with something that both smaller,lighter & simpler to use that still gives great images.
