I have a K1 and I also have a newish Sekonic L 398 Studio Master meter. No, it's not a spotmeter, but every so often I like to switch the camera to manual, and use my handheld light meter and gray card to determine my settings. I also have a few vintage film cameras, some have meters, some don't , some have non working meter, and I use it with those cameras.
I do like going manual and do like my handheld meter...think it's the 'sort of Luddite' in me, as I do like the older, traditional ways.
My suggestion, why don't you keep it, use it sometimes. You may regret it when it's gone.
But that's me and....yes....I realize I'm an old fogey.
Why, I still wish, I could go to a auto dealer and buy a vehicle with a 3 on the tree, manual transmission. I like shifting.
