The Internet makes things easier because you can always find that guy who already has everything all figured out. So tell me, what's it like to be that guy?  |

Captain, you avoid the seams by using the "Auto Blend" feature after you use the "Auto Align" feature. This smooths over the seams for exposure differences. Regarding the lighting, I just pull the lights back away from the lens and very high. This seems to minimize any harsh differences in the lighting/luster.

Hmm, I didn't expect it to do that good a job, but that medal looks pretty great. I guess I'll give it a try and see what happens.

Ray - my first SLR system was Pentax m42, and I developed an appreciation for the quality of their Takumar lenses from the 60s and early 70s. I was wondering if you've had any numismacro experiences with the Bellows-Takumar 100/4? They don't come up on ebay as often or as cheaply as 5 years ago, but could probably be found economically with a little searching. I've been wondering how it would stack up against some of these other oldish lenses. Sorry if this lens has been discussed elsewhere in this forum already. http://www.ebay.com/itm/RARE-1964-S...em1e71a483cb |

I have owned a few 100mm Bellows Takumar (100BT) over the years and still have one for reference. Comparing the sharpness to other lenses, it's a "middle of the pack" performer, better than most of the Novoflex lenses (though some of those are quite good) but not quite as good as the Nikon 105 bellows. It does fairly well for chromatic aberration though is definitely not apochromatic. All in all my conclusion was it is a nice lens and if you can get it for a good price will take excellent pictures of coins. FYI, Mark Goodman has an excellent site where he has tested a range of lenses for macro work. I like his methods, especially since he uses coins as test subjects, and his results correlate with my observations. He tested the 100BT so you can make quantitative comparison with similar lenses. Here is the link to his Macro Lens Tests page: http://coinimaging.com/Lens_tests.htmlContact me for photographic equipment or visit my home page at: http://macrocoins.com |

I am guessing, but I think this is an M42 screw mount that the guy doesn't know jack about what he has,....and he doesn't post anything THAT any one who knows what to look for would look for,(model differences) by examining his one image......I like the type Ray has posted by Vivitar, and not sure if this this the exact same model, due to the lack of photo's, and slight differences, from when it was actually built.. but I really like the canon FL series bellows...and the Vivitar ray has shown us...I think these are the two strongest by far......
I will address... the
"TYPE of USE", or for what camera they were made for and its ability to be used my the majority of camera users...SO as not to be,,CAMERA specific...and not conveniently used by the who of the many camera manufacturers, to cross lenses, from any other manufacturer
to your specific camera.....
I will address this on a new thread as "ON THE CHEAP"

Yup, I'm pretty sure that bellows is m42 since the auction description states it's intended for both Mamiya-Sekor and Pentax, both of which were m42 systems before bayonets took over in the early 1970s.

I just watched this Vivitar Triple Track end and it has been relisted. Might be a bellows for someone; I think I've settled on trying to find a dovetail-style setup for a reasonable price. That's the one I use. A very solid unit, and I'd snag this one in an instant at that kind of money. He might be open to a Buy it Now offer since it went unsold in an auction. |
