Hello!
What exactly is the difference between a macro lens / Nahlinse and a Achromats?
The achromat corrected the color, what color bleeding due to arise.
Emergence of these seams only in the macro area?
Are they dependent of the focal?
Are there any macro lenses with integrated Achromats?
While I understand quite a bit, but I am still very unsure of whether my research synonymous correct.
I appreciate the help.
Antwort von domain:
Primitive: Nahlinse (simple lens like a lens, with all color)
Better: http://de.wikipedia.org/wiki/Achromat
Even better: http://de.wikipedia.org/wiki/Apochromat

Hi,
I got the Nahlinse Marumi DHG +3 in 77 mm for the EX-1 gegönnt.
If interested, I can a few times 1080p frames of the test shots on a caliper-scale rausziehen.
I'm pleasantly surprised of the quality.

oh I understand at least a little bit better .. krischan, thanks for the info, I got the manufacturer page views. daswar interesting.
as far as I understand, is an achromat a magnification optics, so Nahlinse, while 2 color s.die right place moves.
@ domain: thank you for helped me. yes on wikipedia I've already read. apochromatic one is of course a great thing but I think because it is priceless in the area. and because I do not operate in the astronomie am, I let them look at the finger;)
Antwort von domain:
Yes, it is about the correction of chromatic aberration (CA) synonymous with intent lenses. Apochromatic lens, I know but do not because the construction of more than two lenses verkittete and requires so much length would be.
Antwort von chen:
apochromatic lenses of my knowledge are synonymous only in the astronomy and the science is used, it is only for extremely accurate recording media pays.

Apos are synonymous for studio cameras. I had times a APO Sironar (aka APO Sinaron) for the large, 300mm, 1:11, and 90 abblendbar, image circle for 8 x 10 inches + adjustability, which was already at 4 x 5 inches so sharp that you umgefallen is. 3000 DM 15 years ago ...

Hui! From large format Sinar systems träum I (unfortunately) still - you're too envious!

B. DeKid Long time ago. Before 8 years everything sold.
But was really a wonderful work - where the camera was there first, where they have wanted:
1. Cases: Camera
2. Case: optics, Einstelltuch
3. Case: spare parts
4. Cases (wärmegedämmmt) Plan film cassette
5. Case: Exchange box with light-tight cuffs to films Change
The exact setup of the millimeter-cut image and the TTL Spot Metering (3mm) were simply awesome.

Antwort von B.DeKid:
Yes my studio where I have not finished, makes no sense, because I know how carefully you handle with such equipment must be, and how much space / time it takes.
Well will come ;-)
During an internship in the 9 times I had class in D village a Sinar and evaluate the work of White, I was extremely exciting with the care here (a car) was scanned.
No Comparison with the (sports), the shootings I made to date or today's Digital "top stop work" ;-)
Schlicht cult! And what you could really learn!
