Did a quick flash diffusion test with my Tamron 90 lens at 1:1 of a test subject using my normal coke can diffuser on a bracket mounted 430Ex vs using a diffused Opteka 600 twin macro flash ( shot here www.flickr.com/photos/lordv/5577399335/ ). Far prefer the light from the single diffused flash with it's much larger ddiffuser head.

Another elements that will be used in the series Test Drive. Really not much to say about this -- tachometer, shot at night. I really like the glow off the dashboard.

All the parts of the system are now connected. The initial tests were done with the valves removed and a voltmeter used to check that the HT and LT voltages appeared on the right pins. Since they did, the valves could be safely fitted.
The amplifier seems to work, touching the input connection with a screwdriver blade produces noise in the earphone. But the microphone doesn't do anything.
John Deere 8360RT (lead tractor) under test at the University of Nebraska Tractor Test Laboratory. The instrumentation vehicle (yellow) and following tractor provide loading for the test. Part of the test involves multiple laps around the lab's concrete oval track. I took this photo while visiting the Lester F.

NAWCAD Trenton, located in Mercer County, New Jersey, consists of about 66 acres with a total of 96 buildings and structures. The center was used to test jet engines, alternative fuels, turbines, and engine starters.
The main "hangar" at NAWCAD. Im not exactly sure what this building was used for but there are slots in the ground about a foot deep and there are spikes and stands that stick out of them. It looks like you would brace something on top of them. You can see the slots better in this picture.
A toy? Not really, this lens can really deliver amazingly sharp results!
--- Lessons learned:
+ best way to get the grips is to use the lens with the cam (in liveview) tethered to a tv set via DVI
+ the lens should not be used on maximum tilt -- you cannot get sharp results with this adjustment
+ the two lenses in the Lensbaby are not coated, backlight will lead to overlit blurry results ...
+ This is a 50 mm lens, minimum object distance is approx 0,6 meters ...
+ shots were take with the 4.0 aperture, ... 5.6 has a wider sweet spot, but less wow effect
+ works fine in Av-Mode
--- This is how focusing works:
Point the optical axis of the lens **exactly** towards the spot you want to focus; adjust focus ring - if possible in zoomed liveview mode.
--- This is how it not works:
Leave the lens as-is (no tilting); try to focus on an object in the corner of the image via turning the focusing wheel.
--- One problem I came across:
The 5DMkII works fine with this lens in Av mode, even better with additional liveview, but does *not* adjust exposure in *zoomed* liveview! => Firstly wait for exposure adjustment, then zoom in, adjust focus, if possible, zoom out again, shoot. :-)
As seen through my new macro lens, this is the test (calcium carbonate structural shell) of a small sea urchin that was unknown to science until one was purchased on eBay in 2006 and subesqently described by Natural History Museum scientists Simon Coppard and Heinke Schultz. I bought this test on eBay right around that time, unaware of this fact.
::::::::::::::::
Sea urchins are members of the phylum Echinodermata, which also includes sea stars, sea cucumbers, brittle stars, and crinoids. Like other echinoderms they have fivefold symmetry (called pentamerism) and a mouth locatted ventrally. This species is from New Caledonia, and this particular test is about 1.6cm wide.

Photos here were shot using old Canon FL/FD lenses mounted onto the new compact mirrorless full frame Sony Alpha A7 released on November 13, 2013 in Japan. The lenses are all manual focus due to the fact they are old legacy prime lenses. The Canon lenses used for this test:
FD 35mm, f2
FL 50mm, f1.4
FD 135mm, f3.5
FD 135mm, f3.5 (with PL filter)
This photo was taken using the portrait focal length, FD 135mm, f3.5 lens.
