"Does not effect image"

[Nodda Duma]

At work we would use the term "does not significantly impact image quality". A nod to the fact that every aspect of a lens does affect image quality, as well as the fact that the particular aspect has been analyzed/examined and is not a significant contributor to image degradation in that design.

I think we can count on people learning the difference between "effect" and "affect" when they have learned when an apostrophe belongs before an "s". That is, not in this world, ever.

It's "it is" or "it has", and if that confuses then have a gin and it.
Pardon my British.

I had a Petzval with a chip in the rear element the size of a quarter.
The chip did not significantly affect image quality, or to my experience, it performed just as flawlessly as would a non-chipped lens.

With the advent of the internet, I have learned to be accepting of the fact that the norm is bad grammar, spelling and punctuation.

It's buyer beware, always.
Besides that, imperfections in the glass are useful when making a counter offer.

The light isn't well behind in these.

I noticed that person tested the lens against the sun in a blank sky, so there's not much to judge contrast against. And there was no "into the light" comparison shot from an undamaged lens.

Take a scratched up lens and look through it towards and away from the light. When the scratches light up, the film sees that light too.

Great link to a cool expeiment. I was so moved by these examples,






I grabbed my 2 oz ballpein hammer and improved all my lenses for macro!

Kidding!

I never touch or clean a lens unless it's really bad and then it is a careful process.

To the original poster's point, I think if "Schneideritis" actually affected the image quality of the lens, the effect would be that Schneider would have changed their latter designs to alter the coating so that "Schneideritis" no longer happened.

They instead said essentially, 'it's fine' to use a colloquialism, "don't fix it if it 'ain't broke" and made no modification to their coating process. However Schneideritis' affect on people's attitudes toward a lens with the condition is that they are effectively "butthurt" by it regardless of no quantifiable change in image quality.

I tend to have run on sentences, but I THINK I have the grammar right.

Won't be following this rule or any other generated by whoever "we" is in the original post. Buyer's Beware.

Defects are over rated in antique camera lenses. People who want perfect lenses should contact retailers who sell new ones. People buying antiques should pre-suppose imperfections of an aritcle that has stood the tests of time. Almost none of my antique lenses are flaw - less. If one is, you can count on me using words like "minty!" etc. and doubling the price.

Get over it.
