The Moulton Bicycle Company has a custom-built cycle test-track located in the grounds of 'The Hall' in Bradford on Avon.
The Hall is the home of the late Alex Moulton (1920 - 2012) and where the Moulton Bicycle Company is based.
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. :-)
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.

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!!!
Tested these brands and some more. Will need some time to round up the results...
Too many things too do, too little time.

I just wanted to see what the capabilities of the different cameras we have here at home are like.
First is the camcorder from 2004, a Canon ZR85, in the middle is the Canon Powershot A620 from 2005, and last is the 2008 Samsung NV24HD.
I was a little surprised just how bad the Samsung did in this test, and how well the Camcorder did. I really can't get over the amount of detail it pulled out at high zoom. I think the optics, certainly more designed for zoom than wide angles, must have more to do with it than the digital sensor, which just doesn't give very good quality images or videos, otherwise.
The camcorder has taken maybe 30 hours of video in its lifetime, and maybe 100 still photos, the A620 has taken well over 200,000 photos, mostly failed nighttime timelapses with chdk, and the Samsung hasn't taken more than a thousand shots, but if you want a truly pocket-sized camera that can take an interior shot, or a high definition video, without having to ask everybody to keep backing up, and standing closer together, the 24mm-wide (equivalent) lens on the Samsung is the only way to go, and its video quality is actually superior than the camcorder, at least it seems like it on a TV screen.
Too bad she-who-used-to-be-obeyed will be taking it with her when she goes.
As I was out and about today, in Rainier Beach, I noticed a goose that was injured, it had a broken leg and as I talked on the phone to animal control about steps to get it to rehab, it flew across the street! So I drive across the street and searched the park for the limping injured goose, I could not find it, I asked everyone, including this awesome crew of very nice people! They did not see the goose, but promised that if they saw it, that they'd get it to the rehab shelter! Since I wasn't doing anything else, I figured why not get tested for covid again! Shrugs* it was a good day!

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.

This is a composite iPhone photo and editing test.
The TOP image is the original iPhone image, and it is typically noisy (view full size to see noise level).
The MIDDLE was edited (levels, color balance) on the iPhone using Photogene iPhone app and still presents the same amount of noise.
The THIRD photo took the previous, Photogene altered image and, using Photoshop, ran a Reduce Noise filter with heavy settings, then doubled the image, blurred the top layer and set it to 'overlay mode' at 66% opacity. This is a pretty common method for making better, softer, smoky images. A much more rich, deep result.
iPhone image editing apps should consider adding noise reduction and automating some of the more common image enhancement tricks beyond just levels, even if they disguise it and call it something else.

Finally, one of the best ways to improve photos on the iPhone is to use an app that looks at the accelerometer to determine when you are moving the least. Try Steadycam. I use it instead of the built-in photo app.

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.
