technical jargon or the real deal?

Today i was told that lenses can be calibrated to a specific digital camera body i am thinking of purchasing to give optimum results/image quality. So much so that if using a different lens of the same focal length the results may not be as good as those from the 'calibrated' lens on the same body. i don't know if this is a sales pitch so that i don't buy the lenses from another source but it sound like a load of technical jargon...... Anyone heard of this or know if it may be legitimate? I was surprised by the statement and I'm very sceptical - may be i look gullible?

I believe that it is true in principle but that is not how it is done. Cameras and lenses are calibrated to a common standard lens specification for performance. Thus any camera should work well with any lense. While calibrating a camera to a specific lens could be done, it would negate one of the prime advantages of DSLR or SLR cameras, the ability to use a variety of lenses. Leon

At least as far as the new Kodak 14n is concerned.

Apparently, due to the way it's CMOS image chip responds to the angle of incident light, colour banding in the image occurs. This results in a colour shift across the picture left right and up and down.

What's really inconvenient is each lens's angles are different. So whilst the particular colour distortions can be 'programmed out' at the shooting stage, the camera has to store a library of lenses and their particular characteristics in this regard. Presumably the cameras will not be storing anything but Nikon make lens characteristics.

Maybe that's where this 'matching' suggestion has come from ?

generally lenses and cameras are calibrated using standard setups at the factory.

If you have problems you can send your camera and lenses in and have them calibrated together which should give a good result. I have never heard of a local store doing anything like this nor would i believe them. Only if this is done at the repair facility (nikon,canon,...)

Maybe you were talking to someone from a "movie" background - some moviemakers calibrate a set of lenses (read "t" numbers instead of "f" numbers) so as to keep image quality identical. I suppose there would be a noticeable jump in the film image quality if there was a slight change in the lens aperture. On a single still image to image basis this isn't critical.
