Looking for new well old glass

Hey guys, I have some vintage vivitar glass and the m42 adapter. But Im looking for a macro and/or some thing that gives interesting bokeh.
Any suggestions?

Macro is easy, just add some manual tubes to any 50-100mm lens. 10 bucks on ebay.

Interesting Bokeh? Hmm, look for something Russian. Those nearly always have very unique output.

Volna 9 or Industar 61/LZ (neither are true 1:1 macro, but both focus close, the volna closer but is more expensive), both have apertures that change shape at different settings and can produce odd bokeh. My volna 9 is one of my favourite lenses, the MF ring is a joy to use, the odd aperture is fun, and its very sharp when stopped down (tad soft wide open)

Or if you just want something macro and something else for weird bokeh, you could go for the macro takumar 50/4 which is reportedly very sharp, or the tamron 90/2.5 adaptall mount. For odd bokeh, there's the helios 44-2 which gives swirly bokeh, or the helios 40 (also swirly bokeh, but far more expensive than the 44 due to overhyping on flickr by hipsters and because it is rarer than the 44) or a Cyclop h3t which is basically a helios 40 without any aperture control designed for military night vision so its permanently wide open at 1.5 and also gives swirly bokeh (but is not very pleasant to use, very twitchy focus, and not particularly sharp).

Thanx for the info, ill be checking them out as well as the tubes. I do have 3 Vivtar lens here

Seems like you are asking for the Meyer Trioplan 100 f/2.8 lens. It has y very interesting bokeh - nearly unique wide open.

I own a Sigma 90mm/2.8 macro lens, but with normal bokeh.

Ill check that out too, if its cheap its for me

Ok I tried out my Yashica 50mm 1:1.7. what do you think?

The Nikon 200mm f4 AI or AIS both have beautiful bokeh. They go for about $75.
