I have the 25mm Nokton and LOVE it. It's my favourite lens.
This is equally appealing, though I'd really like to see some image samples first. The 25mm does have a fair amount of CA wide open, but man it pulls a lot of light in. I can shoot hand-held in near darkness at ISO 200.
I do wonder, though, if the 35mm EFL would be as appealing on a 2x crop sensor as on the larger ones. 35mm is normal on 1.6x and semi-wide on FF, but on a little MFT it's just a random number. Hmm...
And, to the people complaining about lack of AF, take a look at the rear of one of these lenses. There simply isn't room for electrical contacts around the enormous rear element.
As for the weight, so what if it weighs more than my camera body? Together they're still lighter than the average FF lens.

the rear element of Nikon's MF 50/1.2 also jams the most of throat but they still managed to make an AF-S one at about the same "high" quality as Canon 35/1.4L.

Weight, cost and filter size count against this lens.

I moved from Nikon DSLR to m43 to save weight and size, and I can't see the point of whacking half a kilo on the end of my E-P3.

Also, I've standardised all my m43 filters at 46mm, which fit most of the other prime lenses.

I suspect that the 17.5 Nokton is soft wide-open, just like the 25mm Nokton, which means it needs to be stopped down to around f1.4 - f1.8 to get sharp results.

I think I'd rather spend US$500 on a 17.5mm f1.4, which doesn't exist yet. Hurry up, M. Zuiko!

This simple and seemingly fantastic solution for silent and stepless aperture control was widely used in days before automatic stop-down lenses. The mechanism was called preset diaphragm. You can find preset outfitted fine used Japanese, Russian and German lenses for reasonable price.

You can still get 12mp (no vignetting) out of a cropped image from the NEX 5N using 43 and m43 lenses. Not to mention that you can also get the full square image from the 5N sensor as well. Worth considering...

Yawn, wake me up with they hit F/0.8. f0.95 is not terribly impressive when you only have to produce an image circle 1/4th the size of fullframe. sure the intensity of light is high, but the total amount of light passed through the lens is not worthy of that price tag.

@digifan

Make it look like a Leica lens and you guys just swoon. I'm just saying, you put a magnifying glass on the back of 35mm 1.4 and you'd have a brighter aperture than this. How's that for "technical"

It's not an impressive lens. Lets say you have a viewfinder, lets pretend this is a 4/3 lens and not a micro 4/3. So you have a mirror and a viewfinder. If the viewfinder displayed an image the same size as a Canon 5d viewfinder, this lens on a 4/3 would produce a substantially dimmer image in the viewfinder than a 35mm f/1.4 on a 5d.

Do you understand how that matters? You get how that works? how it doesn't actually gather that much light in comparison to a full 35mm lens? I know you guys can't see past the numbers you are presented, but seriously, use your brain.

@REapper DOF depends on one thing only -- the diameter of the aperture. This is therefore in all respects the same as a 17.5 mm f/0.95 lens on a full frame camera, only the image circle is smaller and you need to crop the image. Cropping, however, doesn't reduce DOF or the amount of light falling on the same area of the sensor. It just changes the apparent focal length.

But distance from the subject does change the DOF and since you crop the image you stand further away so increase this distance and therefore increase DOF

He's not wrong. The light gathering abilities of any "fast" lens on a sensor this small are pretty pathetic compared to what cheaper lenses do on 35/FF. Also your ability to isolate is way down.

By skrulm8 (Feb 9, 2012)

It's ONLY the diameter of the aperture and nothing else at all. It's hard physics. Longer and brighter lenses have less DOF only because their diameter is bigger. Shorter and dimmer lenses have more DOF only because their diameter is smaller. Cropping is completely irrelevant. Take a shallow DOF photograph and crop it in Photoshop. The DOF will not change, no matter how much you crop it.

To estimate how much DOF you will have, take the focal length of your lens and divide it by the relative aperture number. Hence, a 58/2 lens will have an aperture of 29 mm on all the camera formats ever invented. The DOF will be the same regardless of weather you've mounted it on a mobile phone or a full frame camera. Only the magnification of the picture will be different.

This is equivalent of a 35mm/1.8 for 135 small format film when comparing depth of field and angle of view, but it's still an f0.95 lens with regards to transmitting light giving it a 2 stop advantage on a typical fast 35mm/F2.0. Criticising the lens for having a bad performance if you used it on a 135-format camera is ludicrous and akin to trashing 135-format lenses for their bad performance when used on your 645-format camera. It is suited to the smaller sensor of the four thirds-system with the advantages and disadvantages that brings.

For videography applications, the focus throw and breathing characteristics will most probably be superior compared to FF or APS-C equivalents. Voigtländer has a good track record with their previous Noktons in this department. Cosina owns Zeiss, so I reckon they know how to build cinema lenses.

In my opinion, you simply can’t have the video quality of a hacked GH2 in any FF camera. Sizewise, GH2 + Voigtländer 17.5mm is still a lighter combination than any FF camera body alone.

Tele-Tessar T*:

ZV medium format lenses,

Distagon T*:
50/4

Macro Planar T*:
120/4

Sonnar T*:
180/4

Cosina doesn't manufacture any cine style lenses for Zeiss. That being said, many Zeiss cine style lenses, like the compact primes, are based on those classic optical designs listed above. Who knows, Cosina may have taken a design clue or another from there?

17/0.95 provides the equivalent DOF really as 35/1.9 (for US$1,500 for manual focus instead of US$200 for AF). Sending its image to a poorer sensor. Absurd.

D800 is USD3000, but it's new camera. FF could cost not above 2000-2500 USD (used or new).
Anyway, 35/2 is good lens in any system. And rather cheap. As for IQ - FF killed crop 2 forever. Noise, resolution and so on.

Many people use m43 when they don't want to walk around with a huge, heavy FF body or for an opportunity to use the GH2 which is one of the best HDSLR video camera available. The Voigtlander 25 0.95 may be pricey, but it is one of the best performing m43 lenses.
For video, if you're using AF, your not doing it right, so the fact the the CV are MF is not a minus. DOF aside, it's still a bright lens with a nice 10-blade aperture made for bokeh. But it's not a mass produced lens. As such it is expensive, but judging by the high prices they sell for on Ebay auctions, plenty of people are interested in buying them, me included.

Sorry for being rude.

Also note, if you go to full frame, you find yourself stoping down your lens so they sharpen up. No need to do that with u4/3 (they tend to be very sharp wide open, and tack sharp with one or two clicks)

Please stop the trolling.

Well 17/0.95 make 35 F2 is Full Frame performance, except you need 2 stop less ISO for an image with the same exposure.

So assuming you need to use ISO 6400 on your D800, an E-M1 user need only ISO1600.

I would imagine a E-M1 ISO1600 would definitely beat the D800, despite having a lower resolution.

M4/3 achieve it cheaper overall, in a lighter package.

@ijack. Actually no. FF is four times the size as m4/3 so that's the 2 stops there. Also consider D800 uses SONY's best sensor yet while E-M1 use Panasonic's 2nd worst sensor. As people have keep reminding me, they are in different class and in this case, D800 is about 2~3 classes above E-M1 in terms of IQ.

Whatever the size, if the D800 ISO6400, beat E-M5 ISO1600, I am convinced.

And this is benchmark people should use for equivalence, same size, equivalent F stop, corresponding ISO under the same light situation.

If by "poorer sensor" you are talking about noise at equal ISO, then your f-stop equivalence fixes that: you need four times the ISO speed with a 35/1.9 on a far more expensive "legacy format" body.
