Thank you, Maybe I do, but I have had the same wife for 54 years, the same car for 15 years etc. etc. I think this change is the least expensive of the other two! (yuk). The size and weight are a factor plus I am interested in finding out if the image quality is noticeably different. I read an article that said the detail in the highlights is better which has been a minor issue for me.
Size and weight are not significant considering your camera which, might actually weight less than the Z6. Certainly not much significant difference in actual weight.
The weight of your 3100 is 455 grams, the weight of the Z6 is 585 grams. SO, your camera is lighter and smaller than the Z6. So there.
