Has anyone tried the Nikon to M42 Lens Converter or Adaptor, i got an adaptor given a while ago but never got round to getting a M42 Lens, there are some pretty good Lenses with M42 Mounts and with me finding the Pentax Adaptor i am thinking of getting one for my Nikon D5300. I know they will only work in Manual Focus but with the price of lenses i thought they might be ok till i can afford some proper Nikon Glass, i would love to hear some thoughts on these Lenses. My initial thought was to get some for my Samsung Mirrorless, i thought that having a Camera that doesn't have a Viewfinder and relies on the screen for focus might work well, then thought why not the Nikon as well. Having a converter for each Camera means i could use M42's on each of them.
