I would not recommend to put any kind of camera in a pocket without a camera protection. There is so much dust etc. in a pocket that you will harm the camera sooner or later. No matter which brand. No matter which pocket.
It is the same like taking a camera to the beach without camera protection. Even the slightest wind will put really fine sand into your camera, which you can not see, but feel.
I always carry my GRs with a leathercase. As small as the camera. See another thread about accessories for this. I never had dust issues or other issues.
I got a small edc dyneemabag from a german guy on etsy.(ultralightbags or such?), fits the gr's just fine, even with the filterattachment and a spare battery. Works winter and summer everywhere.
The new version has properties that i do value and depending on the price, I'll most likely switch it later in the fall when it has arrived to stores.
Prices for the GR IV are there. 1.499 $/1.349 €.
Many might say the upgrade isn't significant but realizing the camera's technology is over 5 years old,
