Hi Markus, I was finally able to capture the images with the Coolscan 8000 in telecentric mode, with a diaphragm whose diameter is 9mm and with a FOV of 16.33 mm. Zerene mode DMap without scale.etalon wrote:Hello Ramon,
I have one more question concerning your setup: As I saw on your picture, you use the scanner nikkor 8000 in reversed mode (like Robert in his setup, too). Is there any advantage in reversed mode vs normal orientation? Have you ever tried the lens in normal orientation?
The Coolscan is asymmetric and the diameter of the outer lenses have a different diameter. The best quality I get with the larger lens oriented towards the subject and the smaller lens oriented towards the sensor. It is the position that I show in the initial image of this post. I explain this because I do not know how it was originally mounted in the scanner.
I have photographed a silicon wafer,
Next, comparative details of the center, the right side and the top right corner.
the right side
and the top right corner.
As you will see in the center, the quality is very similar, but there is a significant difference on the sides.
Although it is not so pronounced, the same thing happens without the iris to convert the lens into telecentric.etalon wrote:Would there also be an atvantage in reverse mode, if I use that lens not in telecentric mode?
My lens seems to be in perfect condition, ... but I would love to be able to compare this with other lenses: can someone repeat this test?
