This god-awful picture is a test of the Canon 85mm F:1.2 lens, which is a portrait-lens the size of a grapefruit and three times as heavy. This is because F:1.2 is an exceptionally wide aperture, meaning the lens is "fast", it takes in a lot of light at once, good for low-light and also is good for very blurred backgrounds when needed.
Those in the know will know that fast lenses are usually not very sharp at full opening. It's just a fact we have learned to accept. It's generally even true for expensive lenses.
But this is an exception. The picture is taken at full opening, 1.2. As you can see, even at a distance of what, 60 meters, the "depth of field" is very narrow, meaning only the object you focus on is sharp, nothing behind or in front. (This is also how you can see it's taken at full opening.) But I focused on the fence behind the lamp, and look at the fence and the bushes in the focal plane. What detail! This lens is superbly sharp, even at full aperture.
(Click for larger versions. After doing so, the cropped version is viewed at "100%", meaning pixel for pixel like from the camera.) (The photo had a slight "sharpening" in Photoshop. You may be aware that this actually does not bring out more detail, it merely enhances edge contrast.)Below is from the edge of the frame. Not a lot of difference from the center, also impressive.

Not at all boooring!
How about a link to a review of the lens... or (cringe) tell us the price of it?
Is there supposed to be a lady undressing in the window or what. I don't see anything ...
After Coronation Street, this must be the most photographed courtyard in the Manchester/Bolton/Wigan area.
Coronation Street, yeah, thaaaat´s it, haha!
Ah, so you *can* call it a courtyard, thanks. That's what I wanted, but nobody else seem to.
The price? Sorry, too embarrassing.
If all the houses open onto the square, albeit and ugly car park, then I would call it a courtyard.
It seems too small and parked up to be a "square", that would have a garden in the middle, and a road around the edge. Think "Eastenders", Albion Sq is indeed a square.
It is too wide and open to be a "close" too. Brookside typifies a close (is that old soap still running?)
Coronation St truly is a street. I would be wrong to call Corry a courtyard.
To some people a courtyard is enclosed, more like a lightwell inside a larger building, or those little plaza's behind buildings - they drive through them in "The Italian Job" to get to the piazza.
Yes indeed.
This building has the garden *around* the house. Pretty narrow. Widest at the opposite end of where I live. The G1 pictures were taken in that garden.
