Camera manufacturers typically advertise their products by citing the resolution of their cameras’ lenses, the resolution of a lens being the degree of detail the lens is capable of reproducing in the image it projects onto the film. Differences between cameras in this respect are irrelevant for practical photography, however, since all modern lenses are so excellent that they project far more detail onto the film than any photographic film is capable of reproducing in a developed image.

Summarize Argument
The author claims that any differences in the lens resolutions of modern cameras are “irrelevant” for practical purposes. This is supported by the statement that all modern lenses have a high enough resolution that photographic film cannot capture all the detail projected by the lens. This means that a higher-resolution lens will not lead to more detailed images on the film.

Identify Conclusion
The conclusion is the author’s belief that differences in the lens resolution of modern cameras are “irrelevant for practical photography.”

A
Camera manufacturers ought to concentrate on building other desirable qualities into their cameras’ lenses, rather than concentrating only on the lenses’ resolution.
The argument does not include any recommendations or statements about what anyone “ought” to do.
B
Apart from differences in resolution, there is no practical difference among modern cameras in the quality of the images that they produce.
The author never says this. The argument focuses only on lens resolution, and doesn’t offer any information about the other differences that might exist between cameras.
C
Advertised differences among cameras in the resolution of their lenses have no practical bearing on the cameras’ relative quality as photographic tools.
This accurately describes the argument’s conclusion. The author’s claim about the effects of lens resolution on the images captured on film supports the statement that lens resolution, which advertisers focus on, makes no practical difference.
D
In concentrating their advertising on the issue of image quality, manufacturers are making a mistake about the interests of potential purchasers of cameras.
The argument does not make any value judgments or claim that advertisers are mistaken in any way. It also doesn’t contain any information about consumers’ interests.
E
Differences among photographic films in the amount of detail they reproduce have a more significant effect on the quality of the developed image than do differences in the resolution of camera lenses.
The author never tells us anything about photographic film, other than its relationship with lens resolution. We don’t know anything about how film impacts image quality, and certainly can’t say if it’s more or less important than the lens.
