Kit lens 9 megapixels?
Jun 3, 2015 08:51:41 #
Read an article that a kit lens only delivers approx 9 megapixels of information to the camera? Is this true? So any camera with more capabilities say 18 meg--24 meg will not be delivered by a kit lens?
Is this one of the reasons why pro's say good glass takes better pictures? Is it because of the pixels or the quality of the glass itself?

Sounds like something has been taken out of context. Hard for me to relate megapixels to lens quality. Could you reference the article so we could get a better look at the information.

Can you give a link to the article?
When I review DXOMark test results for lenses on different cameras I see that the camera makes much more difference than the lens.
The old wives tale about glass comes from the days of film when even the cheapest camera used the same film.

I have had issue with some of DXO's findings.....It may be just me - but I am told the same thing from others as well.
But, there is some confusing language in our hobby/profession.
Resolution - I think of as the sensors mega pixel count affect on the image
Resolving power - I think of as the lens' ability to transfer the light as completely, ( including sharpness, colors, etc...) TO the sensor.
I am not making a statement of fact, rather I am asking if this is how others describe the impact of the 2 main components in your camera systems?

Oh Brother, that is an Apples to Oranges comparison, the only connection that in both cases you eat the fruit.
They may have meant that using a poor lens (if there is such a thing) is equivalent (not the the same as or equal) to having a camera with fewer megapixels. Seemingly half or less. But it does not work like that, or so simply.
A kit lens may give nearly equal to a pricy one in one situation and yet the same camera with either in a different situation may give very differing results.
Every lens and camera combination result can vary by lighting, aperture chosen, and heavily by the skill of the user. The variation between different sensors IQ is much greater than the differences between lens IQs. As someone else also pointed out, B&W film was more consistent, no sensor so the variable was pretty much the lens and its settings. But again different stops, different results. Generalization are just that, and usually wrong for any given situation. Lenses are not created equal but quality is not an absolute or linear function of price or type.

" Lenses are not created equal but quality is not an absolute or linear function of price or type."
THAT is an excellent explanation for many of my shots...good and bad! And a "quotable". Kudos.

Like others have asked.... Provide a link to the statement...Pretty bogus statement if you ask me...

Sounds like something an unscrupulous camera store sales rep would say to convince customers they need to buy additional lenses as the lens sold with the camera will be crippling their photography.

The gear is only as good as the person using it. Too many people fall into the trap that more expensive gear will make them a better photographer. Thus they never learn their current gear to it's fullest potential.

OK here is where I got the info Go to exactly 59.00 min into the video and there he talks about the lens question above.

He is referring to DXOmark scores for the lens. Any lens can give low scores depending on what camera it is mounted to.

He does make the statement. I'm not really buying it for a number of reasons. For one he keeps toggling between talking about a Cropped Factor Body and a Full Frame Body, as well as Full Frame Lenses being used on both types of cameras with out keeping clear what he is really saying.
Most people feel FF (or to use Nikon terms), FX lenses are better on both FX and DX cameras, because when using a FX on a DX body you are only using the center sharper portion of the image circle. Always made sense to me. Note, I use a lot of vintage "film" glass for my digitals and I've used 4x5" and 8x10" view cameras so I actually know what an image circle is.
The bottom line is relative comparative benchmark rating are kind of bogus. The only really meaningful quantitative measure would be given in line per inch. Old fashion optical bench stuff. But you can do it yourself to actually test your own lens.

DxO is good, as far as it goes. Their results are good for comparing lenses, but they are not the be-all and end-all of lens buying.
