My main focus has been to find out what is lightweight., so this is not a full list of all Nikon, Fuji, and Ricoh camera weights and lens weights.
That said, I have included one heavy camera because I own a Nikon D500, and that weights 860g, I have included it to show where is sits in the continuum of weight. Basically, it weighs the same as two D3500s or three-and-one-third times the weight of a Ricoh GR III, or two-and-a-half times the weight of a Fuji X-E3.
I have also listed lightweight lenses, and camera and lens combos. As you will see, the X-E3 plus a 27mm lens is 30g lighter than an X100s, but the form factor might make the X100s more pleasant to carry because the lens doesn’t stick out as far. If you like to protect your cameras like I do, then putting the X100s in a Fuji leather case is a good option but it bumps the weight up to 605g. But then, after I bought the X-E3 I realised I was going to have to carry a Billingham case because otherwise I would have to carry the camera slung over my shoulder.
