Samyang / Rokinon 8mm f/3.5 fisheye lens.
The lens hood has been “shaved” to allow a nearly full circle image to be captured.

This set of three images is to show what can be done with an inexpensive point and shoot digital camera and an off-camera flash. This Samsung D53 has manual exposure and ISO settings, needed for best results with an off-camera flash.
The manual exposure on this first image was set to expose the view out the windows correctly.
See the next image in the set for the on-camera flash result.
This image was NOT created with a dark ND filter, rather by stacking multiple exposures together using the "Average" function of Markus Enzweiler's excellent program StarStaX, which can be downloaded for free here:

The preceding image was a single frame from the stack, so you can see the difference.
This was another "as-found" scene.
The nice rock has an insect leg on it's top. I wonder how that got there? A nice warm spot to sit for another insect, while it had it's noon-time meal?
Or perhaps a memento of an insect war, evidence of the field amputations that occur even on tiny battlefields.
I had my Nikon D600 in "chase the bunnies" mode, so shutter speed was at a too-fast 1/400th (100mm Tokina macro lens). So at f/16 and in the shade, Auto-ISO shot up to 22,807.
I needed to kill the noise quite a bit in Nikon's new Capture NX-D Beta (it blows!).
I had my generic TTL ringflash mounted, but was in a hurry, and didn't have time to engage the brain. Also, range to subject was enough that I would have had to boost the ISO over the base of 100 that I had the M mode in (1/200th at f/32 or so), and I get a bit flustered when difficult to approach critters finally let me in...

The difference is amazing
Off-camera Vivitar 2500 flash (bare), at camera left.
Triggered by cheap radio remote.
Full daylight background was stopped down to F/32 at 1/400th, leaving only the subject fully exposed by the flash.

This is the screw thingy on the back of the mounting flange of the lens. The camera has a mating bit that spins this one when autofocusing.
This is a single-frame, unstacked image, taken with an inexpensive 10X "finite" microscope objective lens.
Depth of field is only about 11 microns, which is .00043 inches. Yikes. Stacked images made with this lens require the subject to be precisely moved between frames in increments of less than a half-thousandth of an inch!
Lots of dust/oil spots on the D600's sensor, clearly revealed by the very small aperture of the microscope lens. Gotta buy a wet cleaning kit, as Nikon apparently has no intention of dealing with this very widespread problem.
This was my first time shooting fire dancers/spinners at night. Some post processing was required to get the results seen here.
I used my Nikon D600 with a Sigma 70-300mm f/4-5.6 "APO" macro lens with internal focus motor ($100 used on eBay).
I have a bunch of other shots of the firedancers in this set- check 'em out if'n ya like this sort of thang.
