Samyang announces 12mm 1:2.0 NCS CS wideangle for mirrorless cameras

Well, because it's the same (12mm) lens. There's a difference between angle of view (what the lens sees) and angle of coverage (what the film/sensor sees). The lens captures the same information regardless of sensor size, (heck, even without a camera attached) but sensor size does determine what amount of that information is captured. That's how I understand it anyway - please correct me if I'm wrong.

It will not provide the same FOV. It will be wider (18mm FF FOV) on APSc compared to m43 (24mm FF FOV). This is technically an APS-C lens, which will work on m43.

Don't feed the forum's 4/3-troll with meaningful replies... it would be a waste of time...

@yabokkie some food - just for you:

<°)))o><

I would appreciate those who love 4/3" could show us they are educated gentlemen so that we will know 4/3" isn't something to attract the opposite.

Yabbokie on the other hand does not look like an educated gentleman. Educated gentlemen do not troll on forums and are not offensive to people who use a system they do not like.

Not necessarily, while it may be a bit much for casual stills photography if it has good sharpness I could see it being popular with videographers, especially on cameras like the BMCC where it would be 28mm equiv while presumably having much better edge to edge consistency due to cropping.

Looks like somebody who thinks he knows everything. Can you shoot M with action, kids, sports? lol

"Looks like somebody who thinks he knows everything. Can you shoot M with action, kids, sports? lol"

You're proving his point with that comment.

Actually, from a gross oversight, he proves his point... but not quite. While yes, you *can* count on a super-wideangle to provide a very large DOF, at f/2.0 all bets are off. And while kids play nicely at a distance, in the sun, the huge DOF covers the problem. But... and it's a big BUTT ;) here: <b>the oversight</b>.
Meaning, with my Tokina 12-24 (almost always glued to 12mm), at f/4.0 I kinda need to push the ISO to more than reasonable, while being in the middle of a dance floor, for example. Action at one to two meters away, semi-dark... f/2.0 would be damn welcome to get at least 1/100s while still under ISO3200. And at f/2.0, short distance, you can bet your amateur photographer licence ;) that you NEED to be in focus. Wide open and zone focusing is just begging for the right moment to be thrown away, in the pile of junk "almost focused" photos.

@SelfMotivator .. not too many people in their right mind take shots of their kids with UWA.

Barbu excepted :p

however it's certainly not the norm.

Careful - next someone will claim it is hopelessly crippled without stabilization.

@kodachromeguy as they are shooting kids and sports no less!

manual focus such wide angel lens is very easy. Don't understand the complain.

6 aperture blades is really something that doesn't help to push my enthusiasm for that lens...

...7, or better 9 aperture blades should be no problem with a fully manual lens like this.

However, I love to see that Samyang provides that lens with NX mount...

...and I hope that they make all their lenses available for Samsung NX mount.

I had to adapt the 85 mm Samyang (in Canon mount) via adaptor, from Canon mount to Samsung NX mount - which is doable, but hopefully unnecessary in future.

Yes, that is terrible when you have to focus manually.

And also to be fair a Canon DSLR does not have great MF aids through the viewfinder and using the screen can be quite clunky. Mirrorless cameras (for which this was designed) have far better MF aids when using the VF.

to be fair, most canon DSLR's can accept manual focusing screens though.

I used a split prism one on mine for MF lenses.

If you're stopped down, getting the focus exactly right is not as important since DoF is so deep, especially on a wide-angle like this. It's a fine tradeoff to drop the electronics in exchange for a much lower price.

First: This wasn't about manual lenses like the ones from Zeiss eg. it was about _Samyang_ lenses. Check the difference. Samyang lens means:
* No AF
* No aperture control by the camera
* No EXIF data
* No compatibility with the camera electronics

Second:
DoF isn't even compensating on the 14mm full frame for a bad focus point. I tried it on a A99 body and the outcome of these trials led to what I'm posting here.

I have been using the Samyang 24mm F1.4, 35mm F1.4 and 85mm F1.4 on my full frame VG900 without any problems . I guess some people just don't have a clue how to use MF lenses so they should stick with a fully automatic (AF, IS ) lens that does it all. I spent my whole life in the film days with a Pentax 6x7 and 4x5 cameras so complaints like this about MF lenses is just too funny.

This is perfect for focus peaking. I don't think you know what you are talking about. Closing down the aperture before the shot will give the camera a more accurate calculation of the scene. This lens will work just fine.
You are correct about the not having all of the 'features' but this is why a person would buy this lens. Sometimes, you want to set the aperture manually and keep it there without the lens constantly resetting itself. When you really want portrait control, autofucus just gets in the way and focus peaking works very well nowdays.
The lens will not be for everyone, but it certainly has it's place.

I've been using OM/contax lenses on canon EF for I don' t know .. 10 years maybe? i didn't realize there was this huge problem with stop down metering and manual focus. omg!

i doubt we'll see much focus shift at 12mm .. call it a hunch.

you still didn't get that it is not about manual focussing. reading before posting helps ;-)

I did read .. stop down metering no problem, focusing no problem. so what's your problem?

One of the most interesting lenses in history and all you can complain about is how it is MF... well done. for what it is worth with all your expertise, mirrorless (which is all this lens will work on) don't have optical viewfinders, so a big part of your argument is void.

Secondly, just because YOU struggled with MF lenses with manual aperture control does not mean everyone will have the same issue, I think there are enough people around that use adapted lenses that they don't need to listen to your 'warnings'.

I agree with Wolfgang about the focusing. Using focus peaking with wide lenses is not fun at all. Blinking pixels all over the viewfinder. Focus magnification works better but slows you down. I mostly focus my 14 mm Samyang using the focus scale and keep it around f8. Have made a custom Dof scale for it, works nice in most situations. I have no issues with metering.

speaking of idiots..

yes because manually focusing lenses has been a photographic issue for years. if you don't like focus peaking .. don't use it?

I have a 8 mm fisheye on my NEX and I confirm : almost impossible to miss a focus. I am normally an AF addict and AF speed and accuracy is a major issue to me. But with such wide angles, just set the lens in the morning, and you are OK for the remaining of the day. And of course focus peaking is useless because everything is white or red : everything is simply always focused. Imo, AF is really a waste of money / reliabliity/ size / weight for such focal lengths.

But I have to admit that empty EXITS are more frustrating. Now I have only the 8 mm and I can recognise photos by empty EXITS, but when I'll get the 16 mm as well...
