Now finally some serious test-shots to prove the qualities of this lens to you. Here we go, don't expect less than some Siemens-stars from me
To make this procedure less painful for you I decided to hide the complete pics as links under the 100% crops. So if you don't believe me/your eyes just click through to the original. Apart from my feet there is also the other Siemens-star in the lower left corner for you to check that the perpendicular adjustment on my test shots was ok.
Following are the 100% crops first centre, then the upper right corner. All shots at maximum aperture (=wide-open) first row at 10mm:
...followed by 15mm (there are some tests saying the range in between is worse than at both ends of the focal-length)
...and finally 20mm. Enjoy!
When measuring the diameter of the grey disks at the centre of the Siemens-star, I normally go for 200% magnification and divide the result by two, just to make it easier for my eyes to judge! So what do we get here:
10mm centre 6 mm, corner 7-9 mm
15mm centre 7 mm, corner 8-9 mm
20mm centre 7 mm, corner 8-9 mm
At the corners there is a slight astigmatism, meaning that the sharpness depents on the direction of lines.
The obvious loss of contrast in the corners at 10mm gets a little better by stopping down to f8 or so, but not really up to the centre-contrast.
As you can see, the results are pretty impressive across the focal range. MUCH
better than the results from my first copy. And this clearly shows in the pics you take with lens.
Expect some white-dwarf results soon...
And let me show you some (slightly tweaked, but no HDR) shot of what I love very much: Sky, clouds and sun!
