And, that, folks, is how I wound up with 3 systems. 1) The K-1 is my main system. 2) Ricoh GR when size is the main concern, without sacrificing too much image quality. 3) Inexpensive micro 43 kit (Panasonic GX85 with 2 kit zooms < $600 total) for trips when I need the versatility of zoom in a much lighter package than the K-1.
I have 3 systems as well
Although one aint a system camera. 3 formats...
Flexibility in cropping is important to me and the K-1 is great for that. I don't use zooms and now carry fewer primes.
I have a small Olympus 4/3 I use only with the Rokinon 7.5mm fisheye. The weight of this combo isn't much more than similar fisheye for APS-C + camera. I don't know what is comparable FE lens for FF. I love my FE and use it much more than the DA15 I used to carry...
I have a 1" Canon GX9 II for snapshots... [ it surprises me often ]
I use the K-1 with A28/2.8 and FA77. Because of the great cropping ability, this weighs only a few ounces more than the DA15, DA 21, FA77 K-5 I used to carry. I save weight over the rare times I carried the DA35.
I did make a concession with my tripod to save 10 ounces and I end up with the same weight with the Olympus & K-1 as with my K-5 kit. I now have more fisheye fun and fewer lens changes with the K-1.
Keeping weight down is important to me and I struggled with that.
I agree with the comment that there is more to the diff between KP & K-1 than the listed specifications. The K-1 is big but I use it with small lenses. Still miss the K-5
It is interesting there are many K5 To K-1 upgraders in this thread.
