Frage von Sebastian:
I have my three times 1 / 2 "optics for the EX3 undergo a direct comparison. Camera from the window and addressed each with the same setting Optics rotated.
The optics are:
- EX3 Standard Optics
- Canon YH 12x4, 8 CRS
- Fujinon VCL716 / S 16x 7.3 BRM
The latter two are actually SD lenses, but because of their fit 1 / 2 "Hotshoe connector on the delivery of the EX3 belonging 1 / 2" - ACM-18.
To make a comparison to be unbiased, I have the pictures in this post only aware with A, B and C designated. What do you think? Which Picture is one of the Optics?
If I were a couple of estimates received, I will post the resolution ...
(The pictures are also in 720/25p mode, with the Clipbrowser software and saved as a BMP for Photoshop's Forum with the highest quality level in JPGs converted)
LG,
Sebastian
PS The better comparison, I would suggest you post in the following style:
A = EX3
B = Fujinon
C = Canon
Antwort von ruessel:
My tip: Picture B is original EX3 Optics ....
Antwort von Clemensch:
I think to know:
A = Canon
B = Standard Optics (CA's not as pronounced)
Fujinon C =
1,2 or 3 last chance gone.

@ Clemensch:
Without anticipating the results now:
Times I would be interested to know exactly what you mean CAs ... Do you want the times to highlight areas and to post?
And you would have thought that the differences in the use of SD-optics in comparison to the HD-Optics EX3 so low?
Personally, I was honestly surprised. The Fujinon Optics is somewhat subjective, "soft", but when the detail of the Camera a few percent is high, the falls are not as good as on.

Antwort von ruessel:
But if the detail of the Camera a few percent is high, the falls are not as good as on. then go look at 1080 25p ......
Antwort von Sebastian:
Klar, hab ja nix else to do ... ;-)
But if you absolutely want to:
Picture 1 is a magnification from a screenshot of the 1080p standard EX3 optics with the standard detail setting.
Picture 2 is the same magnification, taken with the SD Fujinon Optics and detail to 25%!
I am anxious to see your comment ...

Sebastian
Antwort von ruessel:
Picture 2 (A-2.jpg) has ugly black Kantenaufsteilung, see, eg, bicycle sign "Made in Germany" or below the rim.
Otherwise, poorly comparable, which is focal to differ and the motive is not just a reference image for the assessment of image resolution .....
Antwort von WoWu:
The differences you'll find synonymous primarily in the MTF, in contrast to the values and because you're at 1080 with 76% (HD) to 40% (SD) here.
When you are 720 with 82% to 77% are still in fairly linear range.
There have been quite right trunk ...
Also you have to put it in the corners anschauen. Since the MTF sink only really in the cellar. There is also a significant dependence on the focal length and the distance of the object, in which SD in both cases clearly goes into the cellar.
Still, we have an attempt made to bleed both Objekjive in a Project ... at the latest because you realize that the SD Lens the "glasses" is missing.
But there is, of course, as always, a question of entitlement.
Antwort von Sebastian:
I am currently in the process, my motive of IRT as a reference picture for the public service broadcasters to certify ...
Man, snouts! You're synonymous, but fussy!
My clients get shot but no test charts, but FILMS (and the still mostly as synonymous SD ...).
Sure you can (especially metrologically) Differences note I wanted to do with the thread just show how small these differences are modest (Clemensch had in another thread asking).
I can with the "disadvantages" of the SD-optics live well. Enter me to the standard optic EX3 a blatant handling advantage. Right now would be even more interesting times of the Comparison of the EX3-Optics to correct its expensive HD-Optics. Did someone something in the drawer?

Antwort von WoWu:
Sebastian,
.... make the times for 1080, because at 720 you're almost even in the linear range and synonymous with a template that a spatiale Resolutionzeigt. SD lenses are optimized for 5.5 MHz, ie approx. 33 Lp / mm, whereas HD lenses for the 2.7-fold, namely for 30 MHz or 82 lp / mm optimized.
We have such tests in the 2 / 3 "area with BR-made lenses and if you take 80% MTF only approx. 40% then you see the pictures as" listless "from. - But, as I said, You must of course synonymous in the area of the corresponding resolution spatiale comment. Added to this is that you have optimized lenses in 1080 at 720 a totally different filtering searched in order to avoid moiré, so that even in the Resolutionder reference optik already with a low-pass intervened. time to say nothing the mention of what the Kameraprozessing nor anything about "magic." You'll 1080er was a test does not come around, or you have a synonymous optimized for 720 Optics take (hard to get).
Also try times uniform values (30mm Focal, short object distance and Resolutionin the corners) because in the middle values (60mm, 3-10m object distance and in the center of the image) shows the effects is less strong).
Anything else: The CAC File, in the camera is located, belongs to your individual Lens, not only for the Lens Type. With a lens shift so you lose the precision of your CAC.
Antwort von domain:
The comparisons between lens 24 * 36 mm and 6 * 7 cm Medium synonymous formats were already 30 years ago and currently the minds moving in exactly the same level of the current discussion.
Of course, Asahi Pentax 6 * 7 or 6 * 6 Hasselbladobjektive per synonymous usable for small and they achieved great results synonymous, but against the real top small lenses of Leitz and Zeiss, they had no chance, but came because of the much larger film format, but overall better results.
At the same time I mixte synonymous my own C-41 developer chemicals together to maximize Edge Effects to achieve what today would Kantenaufsteilung.
It was an exciting time, but at the same time I recognized as my befeundeten professionals working: Lenses and most expensive cameras and standardized Kodakprozesse. All the discussions about the last possible quality from specific cameras and procedures they are not interested.
You were more concerned with the freedom of artistic image making without lengthy with a series of tests must be addressed and this is actually up today.
Therefore, I find all the examples shown here are quite interesting, but basically because of "meaninglessness" fairly s.der passing thing.
Antwort von Clemensch:
So "meaningless" would this thread now I do not call!
After all, I have a visual impression of the 2 SD lenses in koop. with the Ex3 obtained.
Where I previously had not the faintest glimmer of how these combinations in practice and in the Picture effect.
Sebastian, I am grateful to you in any event, but two images in the format 1080er could still interesting wircklich. If you ever find time and motivation. :-)
