I need 2 k mounts

Jeff Lopez · 02-26-2017, 09:06 PM

I was recently given 2 Vivitars for Nikon, a 35-105 f 3.2-4 and a 35-200 f3-4.5..I cut the aperture ridges and they fit on my K30 pretty well, but they dont fit on a K5..
I would like to change the mounts to K mounts, I rather do that than use an adapter..I seen these lens on K mount on Ebay..does anybody have some Vivitar K mounts rings to sell or give?
Thanks...

Unless these have sentimental value you are almost certainly better off selling them on ebay and buying the K-mount versions or equivalent.

Edit: oops I see you already cut them up. Never mind.

You could always get one of the flanged M42->K or M39->K adapters and drill the mounting holes.
It'd be interesting if you could maintain auto aperture on the conversion, but you'll probably have to turn the lens into manual aperture only!

Keep trying on the 35-200, it's a nice lens.

As these are F mounts, it doesnt have the A contacts, so yup its all manual..and they work very nice with the green button

Yes, they do work very nice at low light!

That's true too, but I was referring to the mechanical aperture stop down lever. Unless you can manage to hook it all up and line it up perfectly, you will have a totally manual iris lens.
There will be no open aperture metering and no need to use green button as your lens will already be stopped down!
