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/
Ricoh TLS 401, Fuji Superia 400 (accidentally shot at 200. Oops!), Auto Sears 55/1.4 w/ Camron UV filter. Negatives Scanned.
Test roll through the camera body that apparently has seen no use since 1984. The meter doesn't work, so I used the LightMeter app by David Quiles Amat on my Galaxy Note II.
Disclaimer in regard to focus: WOW this thing's viewfinder is terrible. The waist-level finder is OK, but small. The eye-level finder is practically impossible, plus mine is cracked and filthy inside... Just crossed my fingers and fired the shutter.

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.
This is only a test. I am moving to a new apartment. So I haven't got much on my walls...
All hipstamatic.

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.
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.

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.
Ok so first off I know this isn't a fair comparison but just in-case anyone cares this is the difference between a cheap consumer lens (on the right) and a pro grade lens (on the left)
Both pictures were taken at F5 1/60s iso 200 with a SB600 on camera bounced off ceiling set to 1/4
Between lens changing I had a piece of string on the ground to mark where he was standing and where I was shooting from.
So the test is pretty much as accurate as I could make it. Both pictures were shot Jpeg (which I NEVER shoot jpeg but wanted fair results) sooc
So the Image on the left is the:
Nikkor AF-S 24-70mm F2.8G FX
The image on the right is:
Nikkor AF-S 55-200mm VR F4-5.6G DX
The amount of detail in the eyelashes should be enough to demonstrate the difference. But for some reason the DX lens is under exposed.
All that said I know which lens I will always reach for!!!
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.
I thought the cheap macro flash I was trying out (Opteka RL-600) would not be suitable for use with the MPE-65 at high magnifications as it seemed to stick too far forward of the lens thus severely reducing the working distance. However I found I could mount it behind the front of the lens using a ring of camping mat to wedge it on. Facing the twin lights inwards then seemed to work fine.
