Hey team macro, I'm having trouble finding k mount extension tubes in North America for a decent price. I just had to return the ones I bought from Amazon because the k mount on the tubes was far too tight and wouldn't properly mount onto my camera. I couldn't even get it to turn more than a centimeter, and when I did that it took me twenty minutes to pry them back off my camera. I almost resorted to using channel locks. Upon closer inspection it appears that almost all of the k-mount tubes sold on Ebay, Adorama, Amazon, B&H, KEH, etc are all
the exact same tubes. These tubes are listed under different manufacturers for wildly different prices but if you look closely you'll notice that they are all the same set of tubes. They all have 5 parts, poor reviews (if any), are numbered 1,2,3 (or by their mm in the case of fotodiox) and have a little silver pin to release the lens.
Upon reading the reviews it seems that some people have gotten lucky and their tubes didn't try to forever marry to their camera or to each other, but just as many others have had serious issues with these poorly machined, cheap tubes. On Ebay I've found several decent vintage tube sets in Europe and Japan, and even some for a decent price! But that price is negated after shipping. So what's your experience? Is it just a fact that I'll have to pay over $100 for 60 mm worth of hollow k mounted metal tubing? For those of you who use tubes, where did you get yours?
Your help is much appreciated.
