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. :-)
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!!!
Tilt test model showing a large scale RT model on the tilting platform. Model is in the LT museum Covent Garden.
Tested these brands and some more. Will need some time to round up the results...
Too many things too do, too little time.

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.
My kids have practiced Kempo Karate for the past thee and a half years. Last night was their test for red belt. They both were focused, intense and did great. Hoping to have a black belt test photo in about 6 months.
Played around with a zoom blur with this one, as I thought it added to the action (and eliminated a couple of distractions in the background).
