on a serious note, the Yashica is a great camera. There are issues with getting batteries for it, but if you google it, there are workarounds. Not sure what the other camera is - a Contax of some sort??

Thats not much film for a 800km walk... otoh, if you had to carry it...
Well film are not really that heavy. I had iso 800 ind one and iso 200 in the other and that worked fine. The ony thing I missed was faster shutter times.
My digital alternative is a Canon 5D. That would had been 2 kilo more that my filmkit, + I would have to take more care about protection. Whit the filmcam kit I did not have to worry about rain, bumps, thief ect. I just had them in the top of my backpack.
