With the latest firmware update on the XT20 I ordered one today. It looks to be the updates I would need. I've been doing a lot of thinking this weekend on which direction to go and this is the start. More MP for the landscapes= easier to crop and hopefully more DR. We'll see as I'm thinking about completing the trilogy also. That would be a pretty nifty and light kit with the XT20. Just have to keep the 16 in there some how.
