Is the f stop the craziest thing about this lens? And what is its t stop? I wonder if it’s really faster than the t 0.95 options.
Wow, its ONLY $2100!!! I’ll take 2 please…
One for each eye! I’ll take FOUR!!! 😉
To tell the truth it is only a 80mm f/1.7 equivalent ion a full frame sensor. So it is highly priced.
The DOF is equivalent to f/1.7; the amount of light let in is f/0.85.
This is a manual lens. If you don’t educate yourself, you’ll overexpose all your images.
You’re wrong. The “amount of light” is what a full frame sensor gets at f/1.7. What is determined by f/0.85 is called brightness. And no one will overexpose, because everyone knows they have to expose for brightness, not for amount of light.
@uniquename72:disqus is right and you’re wrong. The lens is an f/0.85. This is a simple mathematical ratio of focal length and aperture diameter.
The “amount of light” is that passes through is the same on whatever camera this lens would be mounted to. A MFT sensor records a smaller geometric area of the total light, as a FF records a smaller geometric area compared to a Med Format sensor, but the light density is exactly the same across all formats.
Actually @Hubertus_Bigend is correct. f/0.85 on MFT will get 1/4 of the light that full frame with f/0.85 will get(the same intensity of light per square mm but over 4 times bigger surface = 4 times more light). Since f/1.7 will get 4 times less light than f/0.85, it means that f/0.85 on MFT provides the same amount of light as f/1.7 on full frame. The light will be “stretched” over 4 times bigger sensor, so it means it will be more dim. But the actual amount of light will be the same. Though, to get the same shutter speed you’ll have to bump up ISO and probably you’ll end up with the same amount of noise on MFT and Full Frame( it’s not necessarily that you need faster shutter).
My god, what a parsing of words. The light density is the same regardless of the sensor size.
The rest of the BS soup is subjective and depends on other factors that indicate the quality of sensor efficiency, which at this point in time is edged out by full frame sensors. In any case, the lens is a f/0.85, period, end of story.
Don’t get it? Go into Lightroom and crop one of your FF images. Is that photo now taken at a smaller aperture? It qualifies to be by what you state.
I don’t have FF, I am proud EM5 owner. But amount of light is amount of light and I don’t understand why ‘light density’ is more important.
Have you tried to actually shoot both formats side by side and see if it makes any difference to the shutter speeds? Try it. That’s a real answer. Theorising is nice and all but eventually you gotta let the empirical evidence have the final say.
With the same ISO(taking into account some differences between manufacturers), shutter speed and aperture you will get the same exposure on any system with any sensor size. What and why do you want to shoot something side by side?
What? The argument is saying, f0.85 on m43 is not equal to f0.85 on full frame. Shoot them side by side, and IF the argument is true, then the shutter speed will be different for both formats. But IF the shutter speeds are THE SAME on both formats, well… there goes that myth.
Prove it. Easy. Don’t just talk about it or link to some website article on it.
How difficult can it be to prove your “theory”?
Shoot EM5. Aperture wide open at f0.85. ISO at 200. What’s the shutter speed read?
Next. Shoot 5D. Aperture wide open at f0.85. ISO at 200. What’s the shutter speed say?
Easy. Of course, there ISN’T an f0.85 lens on Canon. THAT’S the real reason the FF trolls have their knickers in a twist.
Side by side would display the benefit of full frame and larger pixel light gathering over MFT. That exercise still does not clarify the issue for those who can’t think it through. A f/x.x lens passes the exact same amount if light per unit area regardless of the body it is mounted to. All else being equal the exposure is the same. The crop is not.
The end point of all this is that FF f/1.7 can do about the same job as m43 f0.85. ‘Same job’ means noise/shutter speed/DOF wise. You need to set higher ISO, but noise will approximately be the same,
larger sensor and the same amount of light will compensate.
Correct, of course. As if the lens would take a look at the sensor and think: ‘wow, that’s a big one, better let some extra light pass through my guts, to brighten up those far away corners’.
You’re totally wrong. I’m sorry but:
40mm/0.85 on MFT = 80mm/1.7 FF and 80mm/.85 (light)
No, the amount of light is not that. The amount of light is not of a f/0.85 lens but the intensity of light in the exposed area of the sensor is. The amount of light is proportional to sensor size. In a cropped sensor the total amount of light is divided by the crop factor. So MFT sensor has half the light of FF sensor.
And this theory should bear out when you take two of the said cameras with lenses and shoot them both, right? Do they? Have you tried them? Or are you just happy talking?

Oh noes another FF dumb nut. How many times do we need to educate these guys?
First you learn, then you talk. I doubt you’ll ever be able to “educate” anybody…
Hit a sore spot, I see. Trolls have feelings, too? Wow. This advances scientific knowledge threefold!
Intriguing lens, but I’m not sure that slight difference in f stop opening compared to a Nokton is going to be noticeable enough?.. not sure if it would really be worth another $1000 over a Nokton which is well known and fairly widely used.
Forgive me if I’m unfamiliar with this Handevision brand, but I don’t believe it has any history unlike Cosina-Voigtlander.
$2000+ for minimal advantage over competitors seems ridiculous. They need to be charging this like $700 or so like the Mitakon lens that’s surfaced recently, then that would be about right and be able to compete realistically.
In theory it gets about 1.5x more light. In reality that depends on the actual transmission (“T stop”), and vignetting can also muddy the difference.
That’s definitely a movie lens, for still shots the Voigtländer is plenty enough already (and the Nocticron is good too).
I’d prefer the Mitakon, as *if* I’m going to go crazy with low light and/or super shallow DoF then I might as well use the Mitakon with the full frame Sony A7s. It perform much better than this Handevision lens.
Though really, I find my GH1 with a RJ Lens Turbo and Nikon lenses more than enough for my needs! 😀
Only a MFT forum can lose itself in endless yes-no mambo jambo wrestliing whenever a fast lens is the subject .
Correct. 😉
m43 users are so spoiled. Haha.
I’ll take the Noctricon over this. Atleast it says Lieca on the front. I’d take the Olympus 45mm 1.8 over this. I’d take ANYTHING over this. If it ain’t .65 I’m not interested.
Who’s behind Ibelux? Mitakon? Anyone with credibility to do a sub-f1.0 lens? Looks interesting but here’s hoping it won’t turn into another SLR Magic (or whoever it was that promised an ultrafast 50mm lens and failed spectacularly in QC) debacle.
If I remember correctly, the first version of the SLR Magic 50mm had problems and it was pulled from production. A second, MUCH better version was released and SLR magic offered to replace the v1 lenses with v2.
I’ve got an SLR Magic 12mm T1.6 and it’s really very good. I was shooting with it yesterday, actually.
Silly Mr Ree, you aren’t meant to use the gear!

By the way, I’m having no debacles with the slrmagic 25mm T0.95.
I hope someone does an in-depth comparison between this, the Panasonic 1.2 and the Voigtlander 0.95. Really interesting concept. Would be fun to stick this on a GM1
I would prefer to see one of those russian sites or guys who love fast lenses for portrait/model photography, as this is the most obvious genre for these types of lenses. The Bokeh Factory on facebook would be a good place for real word testing too., but that place is not into MFT I think.
Yes, the bokeh would be a very important factor for me as well the feel and build
An 85mm F1.7? Only 2 grand? With all the problems of ultrafast lenses? I’ll take two.
Where’s your empirical proof? Absent an actual test, you’re just a confirmed dumb nut.
I happen to know a couple of things, which you don’t because you did not qualify for the extra grey cells. Now back to scrubbing, geecko.
You all missed the point. Completely!
There all countless people with more money than brains or people who just want to flaunt and brag and who don’t care about IQ as much as their image, however shallow it really is. Pun intended. They buy Nike, AIX, whatever … The only problem of this lens is its low price. Make it $4000 and it will sell even better.
Nice a 80mm F1.7 for 2000 euro…….lol.
m43 users are so spoiled. Haha.

The only crazy thing about this lens is the price. I’d rather buy Olympus 45 mm or 75 mm lens.
