20 year old Canon Lens



Frage von aight8:
Dezember 2010

Have a question about old Lenses. I have a 20 year old Canon Lens. Takes it in the course of time makes any Qualitätseinbusen? Respectively. if you were to buy today a new, would have the new the same quality as the old lens?



Antwort von Tuffy:

Old Lenses fungus can get so mushrooms, and if the lenses clear and turbid are not, there will be all right.
I have a forty-year old Zeiss - doing very well!

At Canon, the only question which is the Mount. The FD-Mount can be for example in the end did not adapt to the current EF mount.
If it's an old EF lens, it is possible that the electronic current with cameras not compatible.



Antwort von deti:

Lenses are 20 years old, even if they still have the best possible condition, which now rarely necessary image quality. The Lenses time were all designed for full frame, which leads to APS-C sensors often muddy images. Then there's aging Proleme as chop-celled mechanics, mushroom trimmings, scratching ...
Frankly, I would put a 20 year old lens in the display case, but that no longer work.

This can not be answered generally, but depends on the particular lens. Regardless of condition, it may be that your old Optics is better than some of today's cheap shards, but worse than today's top lenses - or no synonymous. If you type the exact name of your objective views on Google, you may find even relevant experience of other reports.



Antwort von WoWu:

Lenses today are better in many ways, because the development of the glass and the coatings are better, method of application and processing are better and, ultimately, of course, synonymous with the requirements in terms of overall performance in view of the lens that has grown smaller sensors have become higher.
But the difference in MTF between an SD and an HD Lens Lens is striking.
So it's always synonymous einwenig on the application.

If I fade out old things, are often very good. I prefer a kit-lens, synonymous if I waive the AF. The figure is much (!) Better.
Synonymous with not all are there - cheap lenses (I have since a Hanimex example) are always scrap old slightly better (Zeiss, Helios, Pentacon) work perfectly. Have even an old Tokina for the OM-Mount, which I have not even dim.

My J15x8B4IRS is built in 1995, so synonymous already 15 years old. In my view, the images still look very nice, only at fully open aperture and longer focal lengths, you realize that the focus is not constant over the whole image width. And the flange is not synonymous constant over the entire zoom range, which is not noticed earlier, but now in HD already. The Extender can be used but no longer, it's no good for HD.

I still am not sure if it's worth it to purchase a comparable HD-Optics, although it today for less than 12,000 EUR have any. For the new year I set myself the time to test out.

Antwort von WoWu:

Sure, anything goes and pictures make it synonymous:

If one then takes the trouble and time changes on a good HD Lenses to today and the head was raised after the "split" here, but a fall down the eyes of the head and the jaw.

Just something I did before. Once my Canon J15x8B4IRS and then on the other hand something like a Fujinon ZA17X7 6BERDS58. Canon appears in the range below of give to 20,000 EUR or have I missed anything because what?

Antwort von WoWu:

Get yourself a 3-chip head, or get the head changed the MTF to categorize.
If you want to see the Lens, the camera head swallows you agree otherwise anything away.
If you have a chance, you should synonymous adjust the color level of each Lens exactly, because you otherwise changeable only at color variations of the signal to noise ratio for blue glasses. Or you just do not look at those effects, but they give a false impression Picture, which is not really wanted.
Because the goal is indeed to run a Lens, on the synonymous the camera is set optimally, so as if now would you like it and want to see, what is the maximum image quality to be achieved.
Einwenig is fumbling, but it's worth it.

Well, there should there be on my HD Ikegami Editcam no real doubt ... :-)

Antwort von WoWu:

No, really non .:-))



Antwort von Tuffy:

Why do not you look into the subforum if you want to know what kind of camera it could be ...? I think it usually is here to HDSLRs.

Because it can not represent our job - is so synonymous not asking too much to write here

However, it is synonymous to see your job "in which forum I post.

I mean, it must be still there, in a subforum like Final Cut Pro to ask what, without asking the people "which you cut."

The lens model would of course be interesting to find out which will later on it opens up but actually:)



Antwort von WoWu:

will also apply the tips synonymous for camera lenses that do not have glass lenses and not be judged on the MTF .... ?
And anyway .... what really bothers you when synonymous short time has on video .... why do you go then actually not in photo forums?



Antwort von Tuffy:

Ehm - have I missed?

I think the question on the camera model is unnecessary because of Subforums - given the information I have somehow in None as ... questioned?



Antwort von B.DeKid:

People you get along?

I've basically turned me s.aight8! That should make the effort to make his question more specific.


I am still full of the no preference whether their objective babbles about video, so you have so synonymous law.

But how can you give someone NEN clever tip if you know nothing about the Lens?


And for all times to defenieren konkrett WoWu.

You have - rightly mentioned before - the old entirely Lenses in the video mode of a VDSLR can certainly get good results.

Whereas in the photo mode, this is not to be the case.

Is so synonymous somewhere logical.
I mean if the Manufacturer arrive today with some more than 20MP and even the latest glasses that MP may use or exploit only limited numbers.

.............

But I am the subject as I said relatively no preference, if you last the phrase "old Lens" then like so, to the young, the handle yet so next as he has frequently did and only NEN chunks in the room and He explained that it hoped the one.

@ WoWu were ever beeen at photo forum - should check to go really funny how it goes there!

That was not up to me, based WoWu probably had the impression that I am quite disturbed s.der substantive discussion of film lenses. What was not the point, of course - as already mentioned, we went to me only about this but then the TO Biette synonymous make the effort to say just what you want for NEN Lens and what he use it.

This is synonymous performed the points that I can rule out direct

B. DeKid

There are people that is synonymous for example, microscope lenses s.heutigen cameras adapt http://nikonrumors.com/2010/12/15/guest-post-nikkor-19mm-f2-8-macro-lens-review-part-2.aspx ;-))

Nah thanks, kid, no need. There are fortunately synonymous rational types.
And zoff are times does not mean that we should not respect each other. The forum is quite ok.

Edit: Nah kid, I was disturbed s.nix ... Tuffy, I had the impression, has since muckiert .... but maybe I got that wrong synonymous ... So, everything ok.
