NEX-Minolta Compact Bellows Project Complete!


Recommended Posts

<p>I made a (mostly) permanent adaption of my Minolta Compact Bellows to my NEX, with, electrical contacts! NEX-5N with bellows and NEX 50/1.8, quarter pics at f/8<br>

Bellows collapsed:<br>

<p>Unless I'm mistaken those bellows were originally for Minolta manual focus cameras, which is a completely different mount from the AF mount, and that's an E mount lens. Yuri appears to have replaced the lens mounts on the bellows with E mounts and run wiring through to make the aperture control work. (By attaching 3rd party E mount extension tubes to the front and back of the bellows, I think?)</p>

<p>This is cool, especially since they don't make bellows or macro lenses in E mount, so you're on your own.</p>

<p>Correct, this used to be a MF bellows made for the Minolta MD mount system. I then used parts of the Kenko DG tubes to provide full E-mount lens functionality. Collapsed the magnification is greater than 1x, looks to be 1.25x-1.3x and extended it adds an extra 1x, so, 2.25x give or take.</p>

<p>I forgot to include the link to my blog post: <a href="http://www.georgesopko.com/#!/2013/05/nex-minolta-compact-bellows.html">http://www.georgesopko.com/#!/2013/05/nex-minolta-compact-bellows.html</a></p>

<p>No, as it would cost more, at least for me. I am sure a bellows with full contacts would be expensive new. Then, you throw in the E to A mount adapter ($80) and then a A-mount macro lens (~$200?).<br>

This works well and the bellows extension is minimal and probably is where it needs to be for this lens. </p>

<p>Wow I have been Looking for a Minolta Compact bellows to buy for a while now ,and I keep coming across post about Hacked ones..<br /> This however, is the coolest one i seen tho.. I don't feel as bad reading this one as the one that some guy hacked the rear mount to a Nikon F-mount..<br /> Nice Job Yuri.. If I ever find one maybe I should reverse engineer it to produce ones for the mirrorless cameras</p>
