It will never disappear as long as human beings design and manufacture stuff. But the market demands that there will always be a performance standard that consumers can look to enforce warranties and hold manufacturers accountable.

It is not the lens......It is matching the camera to the lens........remember they are not made as a pair. They are made individually within certain specs. They will work great together that way, but someone might want it better. Hence the fine tuning of the two together....A camera that has a fixed lens does not need this because the two are calibrated TOGETHER at the factory.....There is absolutely no way this can be done with interchangeable lenses.

What concept is that JB - why don’t you try to articulate it in some more intelligent way than simply labeling mine as a “dumb response”? And while you’re at it, let’s hear something more specific (and technically correct) than your usual lame one-liners. Surely you’re smart enough to have a technical discussion without resorting to insults - aren’t you? If you find my examples wanting in some way, let’s hear a real discussion - not this troll-like childishness. Several posters (some of which like myself who have actually been designers of precision technology and seen their designs produced) have attempted to explain tolerances to you, and your complete response is a non-applicable car analogy, and a resort to insults when you’re called out. You may not agree on the need to calibrate lenses to bodies - at least one excellent photographer on this thread doesn’t, but his replies are well-reasoned and respectful, and as such, his will be considered, while yours will be labeled for what they are. Personally, I’ve had enough of your bad manners and am unwatching the remainder of this thread (assuming there is one after you’ve again dragged it into dross as usual)

No one has said that! What has been said is they work together within the tolerances....

Maybe not, since the lens and bodies are manufactured separately from each other?

If you cold read with comprehension, the answer would be obvious. Take a remedial reading class, then come back.

Oh yeah?
What thread have you been following?

What a shame that a generally congenial and helpful forum is periodically diminished by one or two “angry old men” trolls like you. Clearly you have never learned that well meaning people can disagree in a respectful and gentlemanly manner and you feel the need to spread your venom and negativity on the rest of us.

I didn't see your certificate of completion. I've been called much worse and I wear those cognomens like a badge of honor. I'm off to "troll" somewhere else. Take care and good luck with that reading class.

Sometimes, putting a known good lens onto a new camera body results in a focus mismatch.

I once bought a Canon EOS 40D body and mounted an existing lens to it. That lens had performed perfectly on two other Canons. But on the 40D, it focused about six inches in front of a subject at five feet! I tried two other lenses, with the same result.

Needless to say, I sent the camera back to the dealer. It came back "repaired." It had NOT been repaired... There was no change! I sent it back again, and they replaced it with a different new body. That one worked fine.

It's not always the lens...

Yep. All human contrivances are subject to lemon status. But there is a norm that we can all expect unlike what some indicate in this thread.
