Different subjects, totally non-quantitative... just an impression...and I do worry about POFG

syndrome.....but I am taking my medicine......so that should be under control... Shun..has

the best possible explanation thus far.. and I will test this soon...

I will try to post some images...although they are not controlled by any means...

 

Ilkka..yes.. I can understand why you think i might jest....but I do think it is true...it is very

strange....

had my eyes tested..and they are the same

 

clarity is tested on tripod....so shake does not seem be the issue....

 

any other suggestions related to coatings/MFG etc...

I purchased this lens in early December of 2007 and was initially was

disappointed in it performance. Nontheless I continued to use it for reasons

that are not entirely clear, other than I could not believe I had spent that

kind of money and was not 100% happy with it.

 

But what is really strange is about mid January, I felt like the lens

performance was improving and I think it is still improving in mid February.

 

Mostly, I believe the sharpness and clarity are improving.

 

Sadly I do not have any quantitative tests.. only my subjective impression.

Having said that ..and now my question.... is there a technical/scientific

reason related to manufacturing of the lens & its coatings, that the

performance of a lens would actually improve with aging a bit... sort of like a

fine wine?

 

Hoping someone who understands and knows lens MFG might chime in.

Thanks

I sell picture on my website (www.printroom.com/pro/e2photo) and I have tried all common

ways to lift the pictures from the site and have not be able to do so. Based on that

experience there seems to be technology available that would make thief of images more

difficult and I wonder whether PN would be willing to evoke such technologies.

 

If someone can lift an image from that site, I would great appreciate knowing that it is

possible. Steven

I use a wt3a transmitter to my macbook pro 2.33, but I only transfer files via FTP to a folder

on the drive, and then import with Aperture Hot Folder into Aperture. I am using 10.4.11. I

have not had any problems

Other than a longer delay possible problem, have there been any other nagging

problems...the couple of comments regarding focus noted....

thanks

steven

I have read as much as I can find on the D3, and what I find is generally pretty positive. I am wondering if

people have had problems or difficulties. I have heard that AF on the D300 might have had some

problems on some cameras.....both the problem reports on the D3 have been very quiet.

 

Steven

Thanks Josh for for your efforts, but I must second, third the notion that talking ads is

terrible..and unacceptable. I'm on a Mac.

Arthur,

Do you have images that show the unadjusted vs adjusted. I saw another persons report, but

they used an picture so it was a little difficult to tell how improve there was. Steven

Thanks Arthur. How extensive of adjustments did you make with the D3 and on which

lenses?

I just down loaded the D3 manual and I am curious as to how people are adjusting the focal

point on the lens in a systematic fashion. Are you using a focus board of some type...taking

an image, making another adjustment, taking an image... or some other method?

Thanks

Steven

DOF is not symmetrical around the focal point with subjects closer to the camera will have more loss of focus than subjects and equal distance behind the focal point. So if you can not use a smaller aperture, I would tend to focus on someone a bit closer to me, trying to take advantage of the DOF asymmetry. The benefit will be small, but could be worthwhile. steve

Josh....From what I can tell, you have worked very hard at keeping the system clean and that is appreciated. And as I had suspected the rating system with all it's difficulties has value to PN and their clients. ("there are twice as many who love it.")

 

I am curious as to plans to "improve things" and whether you are willing at least to some degree to share those ideas? I am also curious as to things tried and failed, and reasons for failure.

 

If PN was interested, I would volunteer my time to help (assuming that I could really do something--not a computer guy, but like working on complex datasets)...I think there is a good chance PN has already considered and rejected most alternative approaches, but that is hard to judge.

"Community requires participation, and too few people are willing to participate beyond the "nice shot" level. Only by creating a community of individuals to whom giving and getting meaningful critiques will we ever get past the constant complaints about ratings and the rating system. "

 

I agree...

 

But if the how people use the rating system is flawed, which I accept, what is the penality for getting rid of it to PN? Put in another way, what is PN resistance to simply removing the rating system, assuming there is resistance.

I appreciate that ratings don't mean very much, at least on PN. If that statement were true, why not get rid of them? What would happen to PN and PN usage, if the ratings system simply disappeared? If nothing, then get rid of it entirely. If there is a concern of PN usage if ratings disappear, then there is some value to them and an effort should be made to fix it. Just a thought....

 

On the other hand, I think I will watch the critique form for the mindless 3/3 rater(s)activity and simply not upload while they are around...

Tonight, I again received the mandatory 3/3 rating of a single individual so I decided to look at the ratings

in pictures in the Critique form which proceed my picture and which followed my picture. Many of them

much better than mine. Much to my surprize all of them (about 20 in a row) had a single 3/3 rating. The

probability of this happening by random chance is extremely low.

 

It seems like there was a single individual sitting online and handing out 3/3 ratings to every picture that

is uploaded. And since there was no comment as to a new user rating, this individual is not new.

 

It is sad that photo.net allows for anonymous ratings. If you rate, you should attach your name to it.

how large are the particles on film surface? obviously a large range.. but sort of an average

for ISO 100 and ISO 400 film?

Craigslist requires visual recognition of an onscreen code before you can post. Is trying

something like that reasonable or would it add too much overhead? I think i just got hit is

morning with a bot (machine or human)

Aperture if your on the mac..

Can the card be reformated? What symptoms are you experiencing? Seem excessive to me. I use both Lexar and SanDisk cards. How are you reading the cards. I had a card reader that was corrupting my CF cards, but they could be reformated.

So I understand the difference between DX and regular lens, but what is the difference between an FX len and a non-dx lens (film) lens in nikon's portfolio?

Thanks steven

I would have to agree with Luis A above. I would prefer to have an expansion of the EV range over more megapixels. I will eagerly await the noise reports on the D3/D300 at higher ISO. The D200 noise above 300-400 ISO is bothersome, forcing me to use flash when I would rather not.

I wish i could find either for sale in the US. Neither Calumet or B&H have them, nor do they seem able to get them. Sigh

I use the Visible Dust by Artic Butterfly. I have used a couple of times in the past with good

"success" This time, I have a dust particle which is a bit more difficult, but I am not sure I am

getting to it as cleanly as I should...hence the location question. I was pretty sure things

were flipped but was not 100%...now I am more confident as to where the dust particle is

located so I can make sure I pass over it. Thanks Steven
