If crazy speed is what you absolutely want than you have to preorder that Handevision 40mm f/0.85 E-mount lens listed in Germany (Click here). Yes, 1,799 Euro to be as close as it gets to the glorious Zeiss 50mm f/0,7 lens used by Stanley Kubrick in Barry Lyndon 🙂

Sample photos looks nice. But I wonder how short DOF it will be with FF.
Similar to a 58/1.2 on full frame.
Might be better value to just get an A7 with an adaptor to use a f1.2 lens of one’s choosing.
This is probably meant for Fuji users…
Ouch 🙂
Yep, get an A7, E to SR adapter, and Minolta Rokkor MC 58/1.2, and you’ll essentially have the same combination, only i’m 100 sure that the old 58 will outperform this chinese lens wide open. Your 1 stop light loss here will be compensated by 1 extra stop, low noise capability of a FF sensor.
Why going that crazy high speed if you can get the same DOF from a 85/1.8 (or a really cheap 135/2.8) and enjoying also a much less perspective distortion for much lower price and probably much superior Image quality; forgot to mention it may includes AF too…
…none are as wide?
Full frame f/1.4 lenses start at 21mm…
Yeah, I meant neither of the lenses he mentioned.
The 21/1.4 isn’t exactly cheap either… Not to mention I heard that it’s really soft wide open?
And if we’re talking about ” the same DOF” then it’s not gonna do if it gets wider than 50, right?
Strictly speaking DOF between a 21/1.4 and even a 3000/1.4 is the same if everything including subject magnification is the same. Subject isolation is different though.
And just saying they start from 21… didn’t think that a 21 is an alternative to a 60 LOL
Oh, right…I remember you mentioning it, but sometimes I forget to use the right term.
Uh, because the lenses you mention only let in 1/4th and 1/8th the amount of light respectively as this lens does. DOF is not the only consideration, more importantly this lens lets you use faster shutter speeds and lower ISO.
Not counting the tremendous light loss that you get by going down to lenses mentioned, your DOF calculations are just plain wrong. DOF does not change with focal length. DOF is only controlled by Arpeture. Thus as long as your framing is the same, your DOF will be the same between 35/1.8 with subject at 3.5 meters, 85/1.8 with subject at 8.5 meters or 135/1.8 with subject at 13.5 meters. So 40/0.85 != 85/1.8 != 135/2.8. Get your math right…
Worth pointing out it’s an APS-C sensor lens not FE.
yep, and then ask right away what does anyone wants to do with 40mm on aps-c. That equals a 60mm lens on FF. If the lens had been 21mm it would have been a hammer. Higher than 35mm FF it is useless for general use, it is just good for portrait, and for that, no need to invest 1800 euros. My Sigma 30/1.4 makes huge portraits, and my Nikon 50/1.4 too. Note that I bought the Nikon for 140$ on E-bay once.
This is fantastic. I love seeing obscure companies push the boundaries of tradition. ALL NEW OPTICAL DESIGN with a concave front element! That’s fairly profound in the optical world, which has been around for hundreds of years.
Kudos to Hande Vision! Bravo indeed folks. I wish you the best with this fine display of unique innovation. An effective 60mm with FF1.2 DOF on APS-C… Wow what a stunning environmental portrait lens that must be. Just perfect for contemporary look.
Um, doesn’t the FE 55/1.8 already come with a concave front element? It doesn’t seem like a typical design either, I mean the typical Sonnar or double gauss.
Yeap, FE 55/1.8 has concave front element indeed
Canon used a concave objective lens on their early-70s FD 35/2. I was an adaption of a retrofocus design to give it a less wide AOV.
The Sony 55/1.8 is a Sonnar with a negative element added to give it a wider angle of view.
Think of the process of adding or removing elements from the front or back as akin to dedicated teleconverters, that’s basically how they work.
Any news on the 12mm ibegon?
Yeah, Im totally buying a manual focus, off-brand, chinese 40mm lens for 1700 Euro. Anytime.
+1
that price is staggering for an off brand unproven lens….It’s also going to be real hard to get good focus with such shallow DOF and manual focus :s

POINTLESS. As said..
Handevision – 1150g at $1700 + add crop body weight/price
Or
FF A7+rokkor 58mm1.2 950g at… Less than $1700
Hmmm tough descision.
More importantly what’s the T.stop of the lens and how sharp is it wide open? I don’t expect pin sharp but if the effective Tstop is even around 1 or a hair above, with decent sharpness at f0.85-1.2 I’d buy a camera just to use this lens.
But something tells me the lens doesn’t start to perform until after f/1.4
