Reversed 14mm Macrography

My first serious attempt at getting good pictures out of my new reversing adaptor for my 14mm lens. I drilled a smallish hole into a rear lens cap to act as a lens hood, and it made a big difference (and makes me feel a lot better, as it was making me nervous having the rear all exposed like that… this was not a cheap lens). Also used a rubber ring for the camera to sit on to dampen vibrations, and mirror lock-up, and the little remote-clicker-thing so that I didn’t have to touch the actual camera. Worked well!

The first two are with the lens reversed for around 6.2x macro, while the last two are with my extension tubes as well, for even more…

I was just testing to see if I could get anything in focus… yup.

Well, the top 2mm of my ring, anyway. At this magnification, there’s no way I could get anything but the very edge.

I remember last time we tried this, how amazed I was to find that mustard seeds have little pits like a golf ball! Now we see that even the pits have pits… which, actually, I’m pretty sure those are the cells. (Plant cells are larger than animal cells.)

And, just in case you didn’t catch that: OMFG THOSE ARE THE MFING CELLS!!!

So measuring along the bottom there, from the middle of the markings, that’s about 1896x141 pixels (sorry, but I couldn’t get it parallel), which Pythagoras says is about 1901 pixels long on an image that’s 3888 pixels wide. So the width of the image is about 2.04mm. And since the sensor is 22.2mm wide, that’s just under 11x macro!!
