Need for ueberspeed: Ernitec 25mm f/0.85
A 43rumors reader sent me this:
“Hello!
I’ve been reading your site for a while, and have noticed how you’re keeping readers up to date about new speedmonster lenses. I have a speedmonster of my own, but as I’m lacking in funds for my study I’ve decided to sell it, it’s a 25mm f0.85, faster then f0.95. Samples are included in the auction, but you have my permission to post them on your site as well.
www.ebay.com/itm/110775644417
Just to let you know!
With kind regards,
Mathijs.”
Here is an image sample taken with the lens. Click on image to enlarge:

7 months ago |that’s not really all that much gain, just 1/3 EV

7 months ago |Comparing it to the Nokton is a bit unfair if you realize this costs less then half of that.
mister_roboto
7 months ago |Heh, yeah I just noticed that.
Thomas
7 months ago |I think it’s crap
Will
7 months ago |The resolution could be decent, but the picture of the lens looks like crap. The build quality of the lens seems cheap but the price tag isn’t all that cheap.

7 months ago |Don’t expect this lens to perform as well as the Nokton.
I have the Angenieux 25/0.95… sharp it is not
Mathijs
7 months ago |Check the auction, there’s 100% crops.
It’s not sharp, but it’s very useable, especially for video purposes. I own another that I won’t sell, that’s for sure.

7 months ago |I didn’t say there is anything wrong with it

7 months ago |Angenieux has a better name for themselves tho. But yeah ‘sharpness’ in general is way overrated in photography.

7 months ago |Combine this with the ISO 25,000 that the GH2 can shoot and you have something that could shoot in total darkness.

7 months ago |… just with image quality similar to a watercolour painting…
Per Lichtman
7 months ago |I hadn’t heard ISO 25,000 or 25,600 mentioned before in the context of the GH2. That highest I’ve seen clips is at ISO 12,800. Could you provide a link?

7 months ago |Just +1EV in Lightroom
Per Lichtman
7 months ago |Not the same – processing happens post-lossy compression, so there’s a quality difference. It also doesn’t help you see more while shooting, or with focusing (either manual or auto) and you can’t check what was visible in camera after shooting. On top of all that, the codec’s have less resolution in the lower grays than the mid to high ones, etc.
But as far as boosting in post, I think we’ve all been there. The results are just rarely worth the effort on severely underexposed footage.

7 months ago |so you’ve seen: http://vimeo.com/31835141
i’d say 12.800 is plenty !
Per Lichtman
7 months ago |By the time that went up, I’d already shot footage for my documentary on the homeless with the patch.
Actually, last night I shot a small amount for it with the exact same lens Andrew used. It’s really interesting to notice how different it can look compared to the Panasonic 20mm Pancake, even when both are set at the same aperture.
But yes, already have several hours of footage at 12,800 – none with the GH2 at ISO 25,600. The original comment just made me curious since it seemed to be referencing something I wasn’t familiar with.

7 months ago |I think the CCTV 25mm f/1.4 is good enough for much better price ($36).

7 months ago |Forget the university Marthijs, (I did) and occupy wall street for instead. It will probably have sharper result

7 months ago |Why do the images look so dark if the lens is so fast
Joe
7 months ago |That’s to hide the heavy vignette. The bokeh, however, is nicer than the typical swirly C-mount.
Mathijs
7 months ago |No, not really. Mostly it’s because it’s shot at night, so the contrast between light and dark is heavy. Secondly, it’s to re-create what I see with my eyes, i.e. the abandoned building looks mysterious due to it’s darkness and spare lighting IRL, the standard 18% gray exposure doesn’t make sense at night (i.e. look at any movie scene shot at night, it won’t be bright). To make up for the dark image I added the first, which is just average brightness and easily shows the amount of vignetting.

7 months ago |This lens is exactly the same as the SENKO/ADL 25mm f0.95. Ive had one before the Nokton came. It vignettes it flares quite badly.
The Nokton is vastly better. Just because this has a f0.85 printed on it does not mean it is…theres another version of this cctv lens but cant remember the name…Tarcus I think.
Anyway heres a couple of videos I did some time back with the Senko.

7 months ago |The images were dark because it’s some old C-mount that will vignette like crazy on the GH2. Nice try, but buyer’s beware, that lens is gonna suck balls!
Hola
7 months ago |Seems everything under f0.95 is dubious. Most of those lenses were not made for photography anyway so their results are hit and miss depending on the camera + sensor you are using.

7 months ago |I have sample of the 25/0.85. Mine is silver and has no names like Ernitec.
Despite what it says with respect to the numbers..
It is slower than the Navitar 25/0.95 and another (no name) 25/0.95- both are compact lenses (very similar in sizes to the Angenieux 25/0.95 in C-mount). Comparing the “f/0.85″ lens to the two 25/0.95 lenses plus the Angenieux (arri mount, Type M2)25/0.95 (T 1.1), I came to the conclusion, wide open, the 25/0.85 is actually (at best) f/1.1~f/1.2. Still, quite a feat considering its tinyness.
However, it really is a 25mm lens. At least the drunk techs who made them got that number right!

7 months ago |Maybe whoever wins it should run a test with a DOF scale to see if it really is f/0.85. I’m guessing it is but has low transmittance like your Angenieux lens.
Zorg
7 months ago |Don’t mix geometric aperture and light transmission.
Geometric aperture (F-number) is given by the aperture diameter and is responsible for depth of field, light transmission (T-number) is caused by F-number AND amount and quality of glass and is responsible for speed.
The difference between the two gets higher at large apertures, and two lenses with the same F-number (same depth of field) may differ in T-number (shutter speed for same exposure), and vice-versa.
Don’t know if the scale on your lenses is given in F-numbers or T-numbers, might worth checking to compare.

7 months ago |i believe it’s an old Fujinon TV lens. Don’t remember what image sensor size was made for. Fair quality.
