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. Larsen Tractor Test and Power Museum in Lincoln Nebraska. tractormuseum.unl.edu/

I decided to see what I could do with a test answer sheet after I had to take the SAT today. I was playing with the focus points in these shots.
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. :-)
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.
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.

Test of an inexpensive Neewer LED Macro Ring Flash FC100. The subject is about 3cm across and is a tricky one - shiny brass. At this distance the flash works well with a shutter speed of 1/160th, f8, ISO 200 but the flash lacks power. If I move away to a distance of half a metre I can't get a decent shot at ISO 200 even at f2.8, the flash isn't powerful enough. But for the money it's very good for real macro work.
Test Roll of Lomography CN 400 in my new Lomogrpahy Konstruktor DIY SLR.
Overall the pictures are okay. I don't think I'd be using it that often, the 1/80 shutter speed is just a bit too slow unless you stop and stand still.
Also it likes to eat film.

A Bristol Siddeley-Maybach MD655 engine, from a BR Western Region Class 52 diesel-hydraulic locomotive, under stationary test at Swindon Works. Taken on an open day, Saturday 13th September 1975. The engineer in charge ...a white-coated, bespectacled, middle-aged man... sat behind the window of a control room at the top of a flight of steps. From time to time he would notch up a handle on his console to increase the engine revs, which were displayed as flickering red numerals on a screen. In the confined space this produced a most satisfying din.
This was one of the most enjoyable photographic expeditions I've ever been part of.
These are test shots from my daughter Lisa's series, 'Into the Woods'.
Lisa was using her iPhone app to take an exposure reading and we used the Canon 600D to test the exposure before taking the images on her Hasselblad 500C.

Pilatus brought the prototype of their PC-24 bizjet to Cranfield this week for water ingestion trials. There's an area of the runway that they flood with water and then drive through it at high speed, making a very big splash!
Sadly, I didn't have time to get in a better position for pictures so had to put up with this long range shot as she turned off the runway after one such run.
