Thanks Pieter, glad you are enjoying them.
As for the camera, it was more to do with which I fancied carrying on any particular walk. I find the Fuji especially good for focus stacking due to the inbuild auto mode it has, and the lightwieght tripod I use with it! The sony is better for long exposures as I have a "proper" Nisi filter set which gives me clean colour balanced files from the ND filters. I use a heavier tripod as well which in the very windy conditions on some days was welcome, as was the interchageable zoom lens as well! I do wish that the Sony could do more than 30s exsposures (the fuji GFX goes up to 1hr) directly in the camera with no external release or timer as well as focus stacking. I know, why don't I use my GFX, well that is another story.......
