Concerning the high consumption of the XT-2, I can tell you my experience since I bought a Patona charger indicating the percentage of battery charge. I am using the grip with two additional batteries and after one hours of shooting, the first battery shows almost empty, then another one shows the same one hour later and so on. In fact, as I put these batteries in the charger, it shows that they are still charged to 60%, sometimes more.
I conclude that the battery level indicated by the XT-2 is completely wrong. What I didn't test so far is the time until the XT-2 shutdown itself by insuffisent electricity power. I don't know if it is only the display which is wrong or if the XT-2 assumes their is no power at all.
I like this new charger as I can quickly verify the level of charge outside of the XT-2 before putting them in my bag.
Coming back to share one of the photos taken in France with the 55-200 mm lens. We happened to be staying in a hotel room with a view over the rooftops toward Sacre Coeur. (I did not bring a tripod on this trip as we were walking most of the time so I was photographing this basilica from my hotel room, some handheld shots and some with the camera secured to the railing with a gorillapod.)
I have a 18-55mm now as I gave my 18-135mm to my daughter for her XT-10. Now I definitely miss my 18-135 because I don't need to change lens all day long and this avoid a lot of risk catching dust on the sensor. It is a globetrotter's lens. I find the quality of the 18-135 lens really good.
