Cutting business

sony-tilt1-001

Yes, it IS (was) a cutting business (with hack-saw and the files etc) in deed.   (It was a reason why I’ve been away a while — normally Zen Buddhist doesn’t make any excuse (= since, if it’s happened, it has to be happened) though, these days, others may mistake I’m dead !  😀  

As a work on front of me, which was to make a tilting bellows for Sony A7 camera.  In the past, I’ve made quite few lens tilting devices and the cameras which can push the character of the wide-angle lens to the limit, exaggerating the effect of perspective in the pan-focus image enviroment.   To make it with the convenience of the DSLR, I pland it using a Canon 5D Mk-2, hence I’ve bought one more body though, while encountering to Sony A7 which got 18mm thin flange-back (distance from the lens mount to image sensor) on full frame format, I changed my plan at once.

18mm flange-back against the most of full frame SLR’s lens of which got about 45mm back-focus, the margine of 15mm or so was ample enough to maneuver the lens even with 30° tilt !   (+Added advantage of the A7 camera is, its electronic view finder can keep showing the bright image even under the heavy tilt and the aperture stopped-doun condition.)

From this point, the rest of work would be a stitch work to make a leather bag bellows. (and the hundreds of the test shots to establish the technical data.)  🙂

I’ll show the finished product and the worthwhile image when they were ready.)
