Tony seems to generate controversy the same way Ken Rockwell does. A few weeks ago members commented on a video of his saying that you shouldn't use FX lenses on a DX body because the DX lens would give better results - more MP.

If everyone is marching left-right, and one guy is marching right-left, you have to wonder if he's right and everyone else is wrong.

Right. I find it interesting to select different cameras to see how much of a difference the body makes. Something else you can do is keep switching bodies till the "bad" lens gives better results that the "good" lens.

Using one body you use to compare both lenses, one will always show better results than the other.

Ridiculous! :lol:

So, my take on this question proposed is ; it is not true what this Tony said about the lens thing, but the type of camera and the creative ability of the photographer. Would I be correct in saying that a kit lens is almost as good as "Good glass" when it comes to quality of any picture?

I suspect the author was either blowing smoke or meant that when using a kit lens for a cropped sensor camera on a full frame camera the resulting image won't cover the entire full frame sensor.

I have taken pictures of my wife's art work using a Nikon D40 (6 megapixels) with an 18-55mm kit lens that were used as book illustrations. So, at least as far as Nikon is concerned, the kit lens is capable of capturing excellent images -- under good conditions.

The pros I know prefer higher quality lenses for reasons such as build quality, weather proofing, corner to corner sharpness, faster focusing and better low light capabilities than is the case for consumer grade lenses.

These characteristics will enable a proficient photographer to capture better images even under adverse conditions.

Yeah...I agree.

A lens is a glorified magnifying glass...there are good and bad...but what you see thru a magnifying glass has nothing to do with pixels.

Below is a worthwhile video to watch on this subject. Tony seems to have a good grasp of his subject matter and is consistent across multiple videos. I don't see any of the top pro/educators like Kelby, et. al., Nikon, Canon, any of the other camera manufacturers, or B&H, Adorama, etc., coming out and saying he is incorrect, all who surely must have a vested interest in what he's saying. The video at the url below has had a half million views. Surely it has come to the attention of all of the people I mentioned above, especially Nikon. I see a lot of people in uhh saying that he isn't credible, his ideas are quackery, and that they've seen where so and so said something that contradicts what he says but I haven't seen a major party in the industry say that, just people in uhh. You can take your pick but to me it would be a clear choice to consider what Tony has to say. When Nikon or Canon steps up and discredits DXOMark and Tony simultaneously then might be the time to consult what is being said here in this forum.

No!!! Gigapixels are a measurement of sensor sensitivity and are never used as an index of lens performance. Used as Tony does it has no meaning. Pure garbage.

Not true. The megapixel count has only to do with the sensor and nothing to do with the lens on the camera.

He has another video out that discussed what he is talking about and gives the math demonstrating the different lens on FX and CF sensors. Watched it, but honestly math isn't my strong suite. If I can find it. i'll post it here.

joer Loc: Colorado/Illinois

Let me clarify.

If you want the very best from your high MP sensor good lenses will provide better images than poor lenses.

Because a lens is offered in a kit does not make it a poor lens.

Even mediocre lenses have sweet spots that provide good image quality.

To put a value of 9MP on a lens in a kit is ludicrous. What lens? What camera? What technique? What lighting, What ISO, etc..
