Richard, I would dare say that Kiev, like most RF cameras, is not particularly suited for macro work.
Unlike the SLR cameras, where in the viewfinder you see what the lens "sees", the Kiev's rangefinder is separate from the lens, and gives you only an approximation of what the lens sees.
So, in order to take macro shots, you would need a relatively complex rig, consisting of close-up lens for the camera lens, but also a rig which would go over the RF/VF "windows". Leica has such contraptions, mostly produced for the M3 camera, in order to use 35mm lens on the M3 - not particularly for taking macro shots.
"Dual Range" Summicron also comes to mind - it was advertised as intended for close-up shots (not exactly "macro", either).
In short, don't bother with macro shots with Kiev. I'm sure that, if you're stubborn and technically minded enough, you could make some kind of DIY solution, but its not cost-effective.
If you really want macro shots, get the cheapest SLR you can find with a macro lens, and you're good to go.
RF cameras are for other types of photos, so neither macro shots nor long telephotos are particularly easy to use, even on those cameras which enable you such things - and Kiev is not such a camera.
Some attachments were produced a long time ago for the original Contax cameras, but I doubt you can easily find such attachments, and even if you do, they'd be *very* expensive.... Not sure those would fit Kiev, either... Perhaps they would, but you would have to make sure before purchase...
