  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Noktor 50mm F0.95

Philip Bloom told us about this a little while back. I am a little skeptical but I would love to be surprised. I am not sure why no one has made a specialty lens with a locked aperture at this speed. The single speed would make the lens much cheaper. Besides, if you are getting this lens, it is for that speed. There are other 50's that are much better stopped down.

I would love to use Leica m lenses on the red but it is not possible without voiding the warranty.
 
It says 'iris gears' so I assume it it not a locked aperture lens.

edit: Oh I misread your post, I thought your said this lens was a single aperture lens
 
This is kind of like saying, "Trying to gauge response at a truck stop for naked cheerleaders."

Is there really any gauging required?? Just make a good lens and the rest will take care of itself.

Ha, you have 666 posts.
 
I have never heard of this company so I am not sure what to think at this point.

Would be interesting to see more pictures that were shot on R1...(?!).
 
I believe this was shot on a GH1. They said the first lens is for the micro four thirds format so the post was really to find out if people would want a PL mount version with an image circle big enough for the Red. Yes they would :)
 
I'm buying. Especially if it's priced for the µ43 market.
 
Don't expect a PL mount. If they are basing their decision off of the poll, we only have 1% of the vote so I would suggest instead that members of this forum write to the company and state that the cine lens industry is about to explode and that a PL mount version would sell like hot cakes, even though the poll does not indicate that.

I wish Red would consider a micro 4/3 mount for the Scarlet 2/3. Olympus makes some great sharp lenses and the crop factor on the 2/3 chip would be greatly reduced. Lenses like this would really help the 2/3 chip with the reduced low light abilities in comparison the the S35 chip.
 
I'd love to see a full size still, or one already down-scaled to 2k/1080p. Unfortunately 50MTF doesn't tell me much.

That still does look soft, but so does the ambient light! :)
 
Sander,

if you could show us the following test sample photos:

1. A wide open @ f/0.95 shot from book or newspapers page with text that from that we can see how the lens is sharp in center and corners.

2. A wide open @ f/0.95 in night with a car lights directed to camera that we can see which sort of flare the lens can make.

3. A wide open @ f/0.95 in night with vapor street lights to see how the lens behave in that situation.
 
In regards to thei pic, is it just me or is that lens showing off some coma on the right side?
 
Sanjin, I have nothing to do with this lens or business. I just found it on the internet and kind of love strange lenses. Yes, those examples would be great but I can't help you to get them.
 
Philip Bloom is doing tests with the lens. His website shout have footage soon. I agree that the lens looks soft but any lens a that speed is going to look soft so we will see hoe it compares to other fast primes.
 
T stop

T stop

They don't seem to say what the T stop is?

There is a problem with glass types and fast lenses. When you use high index glass types some have a yellow-orange tint that cuts the light.

Another bigger issue is that the older glass types had some lead in them to make them more transparent, but Euro regulations don't permit some kinds of radioactive or heavy metal glass to be used or made any longer, so the transmission of the glass is much lower, even more so for the thick elements needed to make lenses faster than f/1.4.

I got a Fujinon 5megapixel f/1.4 12mm C mount, but when you hold it up to a white wall you can see the transmission looks lower than some older lens types, quite a browinsh cast even though it is multi-coated.

We have a Ultra-Baltar 50mm f/1.1 that is quite "water clear" and an Angenieux 50mm f/0.95 that is yellowish, when I get time I will try to see which has the higher T stop, the Ultra-Baltar is marked T/1.3 wide open.

The main problem with f/0.95 lenses is that if you get close up the DOF is only about 1/8" so its very hard to get more that part of one eye in focus. I think its best to use wide open for medium and long shots, and stop down to at least f/1.4 for close ups where you can add some fill light.

I'm not sure that Curvature of Field is a big issue with fast lenses used for taking photos of people since the background on both sides is not the same distance anyway, if you have a group you can have them stand in an arc so they are all "in" focus, a bit like using a swinging lens to get two subjects in focus at once.

Since all new lenses face the loss of transparency of their glass types T stops for all newer lenses will be lower maybe than for lenses made from some older lenses.

Also, with 8 elements there can be some extra loss unless the coating is top notch.

It's good to see a new maker interested in fast lenses though, its good to have one for when you are at the semsor noise floor, the flare can push the shadow detail up out of the compression noise a little maybe.

I have a Dallmeyer 25mm f/0.99 from the 1930's, its uncoated so there is quite a bit of flare, but the extra flare seems to cancel out the reflective losses from no coating and it just has four (or 6?) air to glass surfaces so I think the T stop is about the same as my Schneider 25mm f/0.95 for some subjects. The glass in the Dallmeyer is "water clear" and seems to maybe lead crystal? It reduces the contrast range, something that might have helped with pushed ortho film of its day... Another odd thing about it is the "floating elements" design, the rear group does not move when you focus it...

To measure the T stop you should shoot a white wall because if there is black or white around the test subject it can make the reading go up or down do to lens flare.

Has anyone seen a 50mm Dallmeyer f/0.99 made for Mitchell NC or 2709? I was wondering if they made one. I think Cooke made a f/1.3 50mm for 2709. We have a Dallmeyer 38mm f/1.5 for Mitchell 35mm, and it does have Curvature of Field, given the un-coated design I think its from about 1938 or so.

Does anyone know who made the lens Billy Bitzer loaned to Leni Riefenstahl for her night time torch ski sequence? It seems if I remember right Billy had the fastest lens in Hollywood, so she asked if she could use it, but I have not seen what the FL or f/ stop was and who made it?
 
I also have to say that T-stop is important here. Of course, the F0.95 aperture makes for interesting DOF, and I'll just leave it at that for now, it's "interesting". But how "fast" is this lens?

So far, the few samples posted don't really get me all that excited. I'll gladly take one in Nikon, Canon or PL mount at that $750 price though and really give it a test. Not interested in micro 4/3 as I don't have any cameras or glass for that format.

As Tom said earlier in this thread, if they make a good lens, the rest will take care of itself. It doesn't look like a very sharp lens, but the DOF is so shallow and the small images posted thus far don't really give us a clear picture of what the lens can or can't do.
