Cosina updates Voigtländer Nokton 25mm F0.95 with clickless aperture

By dpreview staff on Feb 13, 2014 at 09:45 GMT

Cosina has announced a slightly revised version of its ultra-fast normal prime for Micro Four Thirds cameras. The Voigtländer Nokton 25mm F0.95 Type II gains an aperture ring mechanism that is switchable between clicked and clickless operation, a desirable feature for movie makers (and previously seen in its 17.5mm F0.95 and 42.5mm F0.95 stablemates). The optics are unchanged, but the updated lens is slightly heavier and larger in diameter. It will be available in March.

"25/0.95 can be hardly called a large aperture lens but should be good for low light video."

What is a large aperture lens for you ???

Maybe physical aperture? A 25mm f/0.95 lens has a front about 30mm across. But maybe you meant something like an 85mm f/1.4 which would have an actual physical 60mm aperture? But why would this be important to you?

So how much less does the aperture click?

It's a lens for video more than for photo. In video the exposure time is limited by your frame rate, so the extra aperture is much more important than in photo; clickless aperture is also important for smooth transitions – something that's not relevant for still photography.

also why 4/3" is a format good enough for video is that our vision does multi-frame noise reduction automatically thus tolerates much higher noise than (single frame) photos.

25/0.95 can be hardly called a large aperture lens but should be good for low light video.

just search Google with "25/0.95" and see what you get,
and compare it to the result of "50/1.4"

And a 50/1.9 could hardly be called a large aperture lens, yabokkie? I beg to differ.

maybe least large, maybe not.
there is no absolute line here so call it what you want.

The f/0.95 only would realize its light gathering prowess if onto a superior comparable sensor (better DR, tonal, color sensitivity), no matter its size. Micro 4/3 is not there yet. It's too much a compromise. A non-compromising lens is no match. Then, there's less 3D looking bokeh blur, and its quality. Meaning, you should understand, the Bokeh is similar to f/1.8 on larger sensors. Not f/0.95. Not light I say; but the Bokeh. Which is not an F-Stop measure; but looks different depending on the crop factor at the same F-Stop, due to your relative focal angle vs. distances (you place your 25mm m43 where a 50mm FF would be for the same angle.) Composing that same angle, puts you into more DOF range, and that's less Bokeh in the [actual] differing mm of the different sized systems. The actual mm focal length does not change.

An equivalent focal mm is not the same as an actual focal length mm, in all of its photographic qualities.

Buy wisely.

Why do you assume that anyone who buys into a µ4/3 system doesn't know anything about photography or what they are doing?

I didn't say that you did. If I had, it would be because it's less, for more money. But if you just want to play, then go ahead and wreak any hope of improving quality offerings (for less cash) from greedy camera makers. That's your freewill. Hey you were first; right? What now? What tomorrow? Everyone knows you are a better photographer, because of the price, right?

Summary: I can see samples.

One day m43 sensors will be better than today’s bigger sensors; but then so will bigger sensors. It's about DOF, and that part will not change. See?

There is nothing more relevant to this lens offering than that. If you didn't know that, it's still absolutely true.

Look guys, this is not about preference. It's about facts. Disagree and spend excessive amounts of cash on this toy, and go make your landscape (DOF), all in focus, stop motion, in the dark shots onto the current best m43 sensor, and we'll talk then. K?

Translation: What do you need this for exactly, and where is its value by price? Don't buy it to find out. Find out first. Your welcome.

Indeed my comment is more toward new photographers, and does not indicate many more knowledgeable folks (than me) may read it. Apparently knowledge and wisdom are on a diet. First adopting toy cameras are all the rage. That makes my comment undeniably relevant. I apologize if I have offended your delicate sensibilities.

Now, exactly why don't I get a voice to disagree?

Calling this lens a "toy" is hardly any basis for a serious discussion.

Except when every photo comes with an automatically generated depth map (not far away). And suddenly your lack of dof is a disadvantage. Sensors will keep getting smaller and ff will be more and more superfluous. 43 is more than good enough for most photographers right now and will only become more versatile in the future.

So NeoDP you are saying that anyone that buys this lens has no Idea about DOF differences across different sensor sizes?
So what makes FF the holy grail of DOF, when there is larger and larger still, there is no limit to how large manufacturers can go if they want.

The ulimate questions is how much do you control do you need?

I am all for progression, and miniaturization; but it's a tool, and unless your mommy is buying it for you, value matters.

Why is m43 the best video camera? Why does it cost more, for less? How do all these disadvantages make its better carry around ability worth it? Not that I don't love that smaller carry ability.

The system does less; but cost more. That's not good. No matter how you slice it. Now if it cost less, you'd have a pony in the race. Still, as I said. M43 is currently TO MUCH the compromise, per system price. In any case, I do not like the lack of current comparative color sensitivity.

Not everyone here knew that this isn't the same as f/0.95, as on bigger sensors. Same light, not same DOF, or better sensors.

Nor do I shoot 645 digital. I suggest APS-C for now.

The manufactures need to get their head out their cases, and make smaller full frame mirror-less system rangefinders, and lenses. But that also would require a faster EVF, and better AF tracking.

Oh I am no pro, I just have a lot of gear - D4, M 240, EM1, XE2 and V1 - each for a different occasion. Where the M43 or even the tiny V1 excel, the D4 just seems to interfere

Not understanding the toy aspect is what is no basis for a "serious discussion". I do understand that’s the opposite of what they want you to see, and the f/0.95 idea they are selling.

So you are saying this is the best video lens? OK.... Hmmmm .... and that’s before we get to the price.

I used to think these lenses have little value if any for photography then suddenly they may become useful, till other makers (specifically Canon) can have their consumer 4K cameras.
