What is the sharpest lens?

go to www.the-digital-picture.com. You can do a comparison between lenses. They have 100% crop pics.
As I suspected, the sharpest lenses wern't made for photographic purposes.
Anyone remember the astronomy lens made by a Japnese company that was used for a 1D MkIII vs D3 acid test?

Very well said. I'd be largely in the same boat. Not with those lenses but say lenses that I own. I'm a heavy user, and a professional, and I'd honestly struggle to say which lens was the sharpest.
I could tell you plenty else about them, such as how much they vignette wide open, particular characteristics, focusing, and any that are *unsharp at which apertures* (which is not the same thing as which is sharpest - ahem 70-200 ahem), but I couldn't confidently tell you which of the lenses I'd own was the sharpest.
53 respondents to the poll can though, so all's well and good I guess.
Even if the title of thread changed to : which of the following lenses manufactured by Canon is the sharpest there are still redundancy.
Would CANON, the manufacturer, step out and announce that...that A lens is the sharpest among all, those B,C and D series are not so sharp...blah blah blah.
So, by tomorrow, Nikon ( or other brand maker/competitor ) would put up a full page ad in the press quoting..Canon has admitted that their lenes are not so sharp.
Funny part is...those who responded, what merit are they basing upon ? By their own test bench result ? On the field ? How authentic is the test being conducted or the result being certified by some organisation or authority ?
No wonder there is reply like the razor being the sharpest or that all lenses are rounded and hence no sharpness exist.
In my opinion, if you are looking for some really sharp lenses, those use by Google Earth, the Hubble telescope, or those on the International Space Station are the direction to go for.
Next question...what is the best minister around ?

The reason for this posting is just test your knowledge and or opinion, but seems like majority of it rather than contributing a useful opinion; most shunning away from giving a matured thought.
This should be a place where we could coined up a topic and dicsuss informally, in a matured way rather than what's happening now <sigh>.

I think several weeks ago, someone already make a thread similar like this
and some CS member already answered
Perhaps they get bored with your question, it's on the page 6, look here
But, anyway,
To be honest, I don't like your word in here,
The word, testing our knowledge meaning is not the same with (u said, and or) opinion
Well, WHO ARE YOU, think that you had the rights to test our knowledge anyway ?
Did we pay you to do some school thing for us so you think you had to test our knowledge ? :think:
Sorry for the "not so nice" words, but really, I don't like your words in that sentence :nono:

test what knowledge
to my knowledge, i know that i shouldn't compare an apple with a giraffe
but hey, here you are doing it, comparing zoom lens versus prime, telephoto versus normal, etc etc etc.
usually people compare COMPARABLE LENSES, like 17-50 tamron f/2.8 versus 17-55 canon f/2.8. or 50mm f/1.2 versus 50mm f/1.4. now, that's a fair comparison, and never mind if we didn't know anything about it.

You didn't offer aything worth discussing on to begin with.....
Bcoz of your polling result, and those who have cast their vote, the result shown that there is only one lens made by Canon is considered sharp. And we never know what type of people reside in this forum, who knows, some malicious guy might use this result and put up some ads like saying....
according to ClipSnaps' polling result, Canon has got only one sharp lens, comparing to ours, all lenses are sharp.
Then ClupSnap will be landed in deep trouble. Why ? Bcoz they allow such polling to happen that's why. Youngman, please be sensible about topic like this.
You should have been concentrating on how to improve your photography instead.

At last a more matured answer.

Do you need to be so mean? Probably someone is a lawyer or an English teacher by practice but please be more sensible to the layman who simply choose a little ambigious/vague word.
Perhap scared of being tested?
Someone ask a friend a question? and his friend reply,
"what a silly question? you're wasting my time with this silly question. Do you want to test me?"
Or
":sticktong:. blabla bla <some sarcastic remark>"
Or
"I'm sorry but just to let you know you won't find a definite answer for that"
Or
"I don't think it's fair to phrase your question in such a way. But perhaps, I could try to answer your questions ....."
How do you feel for each of the reply being on the other side( the poster)?

i would tend to agree that most of the replies are a bit nasty sounding, but do try to understand, the question that you had posted is rather poorly constructed. Like mentioned by night86mare, sharpness probably should be compared against lens of similar types, and more specifically, a certain aperture range even within the subgroup. Only then will more meaningful replies be generated.
Food for thought, what really is sharpness ?? Are we all talking about the same thing ???
Do read the link attached below, rather interesting, but difficult to digest

To be honest, if you want a mature discussion then you have to ask a mature question.
You'd do well to be mature enough yourself to read through the comments because there are some serious points in there. Admittedly some of the slightly more off hand comments do not help with getting to them (including those by myself) but I have made a lot of salient points in there too.
Let's have a serious, mature discussion then. These are some questions that I'd like to ask you:
[1] How would you tell which of those eight lenses was sharpest yourself? Refer to post 22 if you need some options.
[2] Do you honestly think that more than the very occasional person on this forum has had direct experiences with all eight lenses to be able to compare them? There is engrmariano, but even he admits despite extensive usage he couldn't tell you which of them was sharpest.
[3] Do you think the 74 people who have voted on that poll have really had better experience with those lenses than engrmariano?
If you cannot answer [1] satisfactorily, then how do you expect other people to be able to do so? If the answer to [2] is that people on the forum do not have direct experiences with the lenses you've mentioned, then how do you expect them to give you anything other than a guess or hearsay? And if the answer to [3] is no, then your poll is a waste of time.
None of these points are new, I've made them all already in the thread prior to this.
The best thing I can think of to compare your question is,
Which of the following animals would win in a fight to the death:
[1] A Tiger
[2] A Shark
[3] A Pterodactyl
The points being, no one can answer that question, there are too many variables involved.
No one can answer the question because no one knows, no one's had experience with all these animals, and it'd be quite impossible to say as it'd be impossible to stage a meet. Yes with lenses someone can go and do a scientific test, but I'd consider it extremely highly improbable that anyone on this forum has.
For too many variables (Which tiger? Amur? White? Sumatran? etc) read, how do you measure sharpness? In the centre? In the corner? Stopped down? By how many stops.
My very first post in this thread, second only to your original post, was perfectly serious and devoid of any ridicule. I only got funny when more and more people decided they were qualified to answer the question. The vast majority of them if not all, simply are not.

Ahh Gentleman, the gear measurebators strike again with massive amounts of wankery a fist.....
To the TS. Child, most any decent lens today will outresolve the paper you print on anyway so it makes precisely bugger all difference which is the sharpest. 99.9% of users are never going to get the maximum out of a lens anyway so it matters not one bit, unless you are a gear masturbator or one who just collects gear for it's bragging rights ... which is probably 8:10 amateurs in Singapore.
