Macro extension tube

[macrob]

Anyone know where to buy the macro extension tube for PK mount?
Since I doubt the quality of items listed on ebay, so I would rather view the item locally
Seems there are genuine pentax made M42 mount extension tube, but may be not very convinent for use.

Actually ProOPTIC made some ext tubes for Pentax KAF, you can get them from eBay

...


I think I saw some Kenko 25mm ext tube in a couple of stores before, can't remember for sure ...

But AF isn't really needed for ext tube, you'd better shoot w/ MF anyway

M42 ext tube is really hard to use. Better get some Auto tubes which you can use as normal K/M lenses.

You can use a cardboard tube to achieve the same as w/ these cheap manual ones

Interesting!
But seems I cannot bring that kind "Macro lens" outside
If I do so, must be thought crazy

Raynox lens are v popular for Panasonic users, anybody tried using it as an add-on to Pentax Mount? Which ones are gd?

think most close up lens Pentax users are using Canon 250D.

If you have an old teleconverter that has been destroyed by fungus, dismantle it and take out the entire inner assembly... the remaining part will become a good extension tube after cleaning. I have done so with one teleconverter and I'm extremely pleased with the results.

The only problem... it lost mechanical contact with lens aperture lever, thus it will work only for lenses with aperture rings and will not work with "A" settings on such lenses.
