In reply to Big Ger:
I have always had a dslr my last being a Nikon D800 plus the 24-70, 70-200, and a 300mm lens. I enjoy a variety of photography including landscape and portrait work, mainly studio based. I am now 62, and about 3 years ago I found that lugging all this stuff around was getting tiresome so I came to the decision to sell the lot snd buy into the Fuji X system, and I have never regretted that decision. I have just upgraded from the XT 1 to the XT 2. The build quality of the camera and lensed is superb, and the image quality of the lenses is outstanding.
It might be worth considering mirrorless.
