@stonebat are you saying that the DOF Calculator is useless, or do they have to make a clause for these two or at least one of them? http://www.dofmaster.com/dofjs.html

@stonebat Okay makes sense. Especially at the short DOF shot "test." I can see greater differences being apparent.

The only reason, I say it's possible that one of these is not true stated focal length is because I have read that the Pany 20mm is closer to 17mm. Okay, let's wait for the full test, but it looks like a nice option.

@stonebat

I think you're being fooled by the coma of the Voigtlander. They look exactly the same in his examples, just the Voigt is hyper soft. Been saying this for some time now... those things are almost unusable wide open.

And the reason you would use an 0.95 is to get a sharp 1.2~1.4. It's rare to find a sharp 25/1.4, this is the way you get it.

@stonebat

I'm always eager to learn.

*I've always carried hyperfocal charts (a habit from non-reflex Eyemos) and never heard of depth of field varying between lenses of equal focal length. Please direct me to any literature to explain.

*Coma is only one of the possible reasons the Nk25 is less sharp when close up and wide open.

(Let's be specific here: I'm not going to run with either of these samples-of-one when investing in kit).

The latter tester speaks in pejorative terms of laboratory testing. Bad sign, bad science.

When you eschew science, seek metaphor and blur distinction , you're expressing your own passion. Impressions matter and we should listen.

I've got a mate who stopped repairing cameras and lenses. I'm not going to drag him back to his bench to test these lenses. But he'd be able to tell me with a shrug of his shoulders what each does and why they were made that way.

Let's wait for real rests, as you said before.

At last, we have a true thread for the current bun-fight comparison between the Voigtlander NoktoN and the SLR Magic prototype competitor NoktoR:

Which fast 25mm MFT lens?

@jjay Very nice. I'm having some trouble with blue chroma on lights that appear in frame. What are your camera settings and aperture with this lens? Thx!

I'm absolutely in love with this lens! Shot this entire video using mine, also with unhacked gh2 on glidecam hd2000. Focusing was tough, so there are a lot of mistakes. But i don't care :-)

@jjay Ya, I'm returning my UV filter - appears to be useless

@jjay What white balance, and iso did you use? Thx!

I've no had any issues strapping my follow focus ring to the lens. In fact, this is my go to lens for rack focusing at the moment. I use the Lanparte follow focus system

The Voight in Korea has dropped significantly since I bought mine. They are about $788 with the current exchange rate. I dont think there are different types.

It good that competition brings the price down!

Is it just my model or is it normal that when you get to extreme apertures like f14 or f16 the aperture ring gets stiffer as you change it to those? Thank you!
