Panasonic announces Leica DG Nocticron 42.5mm F1.2 (again)


Alongside the enthusiast-oriented DMC-GX7, Panasonic has announced the Leica DG Nocticron 42.5mm F1.2 – the fastest autofocus lens ever created for the Micro Four Thirds system. If you’re getting a sense of deja vu that’s because Panasonic actually announced this lens already (sort of) at last year’s Photokina tradeshow in Cologne, Germany. But what was then a dummy lens behind glass now appears to be a real product, albeit one without any firm availability date or pricing information. 

The Leica DG Nocticron 42.5mm F1.2 is optically stabilized, and covers an effective focal length of 85mm on Panasonic and Olympus Micro Four Thirds cameras, making it an attractive proposition for portraiture and low-light candid work. Details are scant, and we’re expecting more information later this year.

Press Release: 


NEWARK, NJ (August 1, 2013) Panasonic today announced the LEICA DG NOCTICRON 42.5mm F1.2 lens, the fastest (1) interchangeable lens in the Micro Four Thirds standard for the LUMIX G Series cameras.

Previously, Panasonic has marketed interchangeable lenses meeting LEICA specifications, including the LEICA DG SUMMILUX 25mm/F1.4 ASPH. and the LEICA DG MACRO-ELMARIT 45mm/F2.8 ASPH./MEGA O.I.S. The name “NOCTICRON” was defined by Leica Camera AG for this lens type continuing LEICA’s legendary elements of large diameter, high quality lenses. The LEICA DG NOCTICRON 42.5mm/F1.2 achieves the fastest (1) F1.2 for a Micro Four Thirds interchangeable lens, becoming the first large diameter, high performance NOCTICRON lens. 

Panasonic will continue to further advance its product development to meet the diverse needs of customers in the globally expanding Micro Four Thirds market. 

Note 1. For an AF interchangeable lens, as of August 1, 2013, according to research by Panasonic. 

Note 2. Details of the product specifications, the date of release and the price are yet to be announced.  See the lenses road map on our website.



That is a Very nice lens. I bet its price will be Very High as well.


This looks expensive, at least 1000€ AF and OIS – waow!
and for dof only f: 2,4/85 mm…
but even better then the Olympus 1,8/75 mm – dof – 3,6/150 mm


If they cannot release it this year maybe it will be announced again next year. LOL.

Look good but size, IQ and price are unknown. I cannot wait to see how it stands against Fuji 56 f/1.2 and Canon 85 f/1.2L


Nice, f/1.2 to f/1.4 seems to me to be a sweet spot for m4/3, still get nice shallow depth of field especially with a 42.5mm lens (about 28° diagonal FOV). F/1.8 seems great on APS-C. Rarely a need to go larger aperture than that, and if you need to there are always full frame cameras.


“The LEICA DG NOCTICRON 42.5mm/F1.2 achieves the fastest (1) F1.2 for a Micro Four Thirds interchangeable lens”

DPreview should point out marketing lies when they paste them.

I won’t believe Leica has never heard of the f0.95 Noktor hyperprime, which came out ages ago. I won’t say the Noktor has better IQ, but clearly Leica’s above statement is BS.


The footnote did specify AF lens.

That line immediately hit my buttons too – I thought Voightlander might be disappointed to hear it- so I checked the footnote.

Still I wish that they’d just state that in the body of the release, not as a footnote.

Your name describes your intelligence


This lens sounds quite promising but “Nocticron” ?
That is name is…marketing $!/”@%* lol.

In Leica territory a Noctilux is “currently” F0.95
A summilux is F1.4
A Summicron is F2

So this lens is a mix of F0.95 and F2 all together (Since the use of “Lux” is impossible due to Nocti”Lux”) ? lol
A F1.2 lens. Hmmm No ! A Nocticron of course ! xD

I’m not criticizing the lens…but just the name employed.


I like the name, it is catchy. Sure, it sounds more like a giant killer robot, but it is preferable to Touit.


I wonder how much better this is compared to the 45 1.8..


It’s a lot better at wider apertures than 1.8. It’s also unlikely to be noticeably better from 1.8 onwards, with the Olympus being so good already, perhaps on the border of possibility.

I’m stopping my plan of getting the 1.8, until the price of this forces me to return to that plan …



Very nice portrait option for M4/3. This is what we were waiting for since a long time. The Oly 45/1.8 is a great lens and not expensive and does the job for many but there was simply no real alternative if you want it…
Let’s hope this new lens is on par with the Pana 25/1.4 or Oly 75/1.8 in terms of IQ.
I don’t think it makes much sense to compare this lens with FF systems. M4/3 is for people who want excellent image quality and a light weight system. If you want shallow DOF then get a FF and don’t complain. I got both and both systems have their pros and cons.


well said.

I can see a number of applications (professional) where I would use this lens on my GH3 or EM5.


DPR should stop using the term “effective focal length”. It is misleading.

It is better to say “has FOV of”.


Seeing continuation of collaboration between Leica and Panasonic in lens-development for Micro Four Thirds System is a wonderful news! This would be my choice for portraits and low-light shooting, particularly in combination with Build-in O.I.S.


From Dof prespective; it will act like 85 f/2.4 on 35mm FF

a 6D + 85 f/1.8 will have shallower Dof
Also, IQ wise, 6D + 85 f/1.8 @ f/2.4 could be better than this lens

35mm FF still has it’s value when shallow Dof is needed




Full frame is undoubtedly the way to go if shallow DoF is a very big priority. However, given the precedence of high quality primes on M4/3, I’m rather confident this lens will beat any 85mm f1.8 prime in overall IQ, even if stopped down to f2.4 or a bit further. Of course, portraiture tends to be one area where technical IQ points don’t matter than much.

IQ wise, a 6D with an 85mm f1.8@f/2.4 will almost certainly not significantly outperform a current M4/3 sensor with this lens at F1.2. Once you stop down two stops, FF begins to lose to the more efficient small sensors, and Canon’s FF cameras already lag behind newer M4/3 sensors in dynamic range.

Still, want the potential for shallower DoF? It’s certainly smarter to go full frame, especially when you start comparing prices.

While it’s certainly true that FF has more flexibility when it comes to DOF control, it’s less of an issue at these relatively longer focal lengths. Where M43 is most constraining is when trying to shoot wide angle shots of large subjects while trying to blur out the background. That’s not really the task that this lens is aimed at.

Yes, I’m sure you can concoct some specific counter-examples, but I suspect that they’d be much more the exception than the rule for the people who’d buy this lens.


You just had to, didnt you.


It’s not the lens it’s fault but the m43 system for having a tiny sensor. With DOF control you can create great atmosphere in pics. Serious DOFFERS need full frame. On the IQ question. Of course full frame delivers better IQ than m43. Better ISO and better sharpness.


For really serious DOFFERS full frame is just a toy camera. Really serious DOFFERS use medium format.


sure and really really serious DOFFERS use large format.


So you do get the point. Nice. Now stop whining.


congratulations! first dof/equivalence related post. 🙂


To goshigoo: M43 still has it’s value when DEEPER Dof is needed. Low light conditions, a group of people in two rows and no flash permitted – you understand what I’m talking about… So at least you can be sure everyone can be in focus…


I agree.

However, I rather enjoy having room in my shoulder bag for stuff other than just camera gear.


For those wanting to compare this lens to a full frame 85/1.8, if you head over to DXO Mark you’ll find the Nikon 85/1.8 tied for first overall with the 85/1.4, both slightly edging out the $6000 200/2. I had to look for a while but I eventually found the Olympus 75/1.8. If that lens is any indication, this new 42.5/1.2 doesn’t stand a chance.


35mm so so, might as well go the full monty and medium format or large format. 35mm can’t compete with the lens. These crop sensor systems complement a MF system very well…


f/1.2 would be awesome, but I wonder how much better it will be than the already superb 45 f/1.8 from Oly, given it will be probably 4x as expensive?


Was any prices announced yet?


Epic! I have a good feeling about this one…. I love the Leica 25mm 1.4

Chaitanya S

good addition to m4/3 series.


My 2 most important takeaways:

1) Leica designation practically guarantees this lens will be ludicrously expensive, as if the f/1.2 aperture didn’t suggest that enough.

2) AF/MF switch on a M4/3 lens AND an aperture ring. For the love of all that is good, FINALLY.

If the IQ of this is good enough, which it almost undoubtedly will be, I’ll be very happy I held off on the 75mm f1.8 for this lens.

shigzeo ?

If the aperture ring is mechanical/electronic like Nikon’s AFD aperture rings, great. If not, I don’t see the reason for it other than looks.

Of course, Fuji’s lenses have fully electronic aperture rings for some reason or other- probably to complete the look of their cameras.

42,5 and 75 are very different focal lengths. I’d think they would complement each other well rather than compete with one another. 1,2 is certainly fast enough even on M43.


Well, personally I don’t care too much about the aperture ring myself, as the OM-D has two dials, but if I were using my secondary body (a G3), I’d be very glad to have direct aperture controls so I can save the other dial for exposure comp or shutter speed. The AF/MF switch is more useful to me as it simply saves me a button.

As for the 42.5 and 75mm focal lengths, I agree and disagree with you. In a general sense, yes they are very different focal lengths. However, for my personal uses, both would generally applied to portraiture. As such, for me having a 42.5 is much more important than having a 75mm as it’s more versatile overall. My main reason for going with the 75mm would be greater subject isolation, but this lens should match it or be better in some scenarios. It’s virtually impossible this lens will surpass the 75mm’s sharpness though, but again that’s not a priority to me.

In any case, it looks to be a great addition to the system.

Now if only it were weather sealed…


I might get this because of the aperture ring. It’s a definite ergonomic advantage of the Fuji x cameras over other brands and panny seems to have realised that.

shigzeo ?

I take it you are not talking about the Voigtlander 75/1,8. (I admit I don’t know enough about MFT.)
