Do master chefs trade chicken parts, plumbs, and cups of water?

They trade recipes.

Knowing that a given photograph is a good photograph is great. But that won't help anyone do the right thing to make their next photograph a better one. It's not whether this image is good or that image is good, it's knowing what makes them good. That is information that can be applied the next time a picture is taken.

But not if you only get one or two ingredients in the recipe. DxO gives some of the ingredients, but not enough to make a dish. And their quantities are a bit suspect. They dont count ISO performance for very much in their final score.

And Master Chefs don't share recipies. They guard them with their lives.

DXO, Just How Important is DXO to You?

DxO uses images created under controlled settings to measure the quality of a sensor or a lens. They control the settings to eliminate variance in environment. The result is a measure of the sensors or lenss ability to capture an image. The IQ is used to measure the sensor or the lens, not the other way around. To use it to compare camera systems just exhibits a COMPLETE misunderstanding of what is being tested, what the results mean and what the scientific method is all about.

DxOMark reports on Image Quality. They never pretended to test anything else. <snip>

NO! NO! NO! NO! NO! NO! NO! NO! NO! NO! NO! NO!

They report on SENSOR and /or LENS quality by measuring what happens in controlled lab settings!!!!!!!!!!!!!

And they have never claimed to anything more!

Alternative to Canon 7D Mk II

<snip>. Just pointing out that OTHER gear can be had for less that scores as well or better than the new 7DmkII on DxO's battery of tests.

<snip>. ;)

Not that they provide evidence that those scores corrolate with better final results.

Best camera for street shooting

Leica M. That is what I would use, if I was dedicated to street.

Prime Lens Usage Suggestions Needed

You make a good point. A lens with certain limitations does make you slow down and do things a bit differently. Not always a bad thing. Thanks.

Maybe you need to try that limitation. Just go out and shoot with it for a week or two. See what you find out.

7DM2 16000 ISO

I did know that it was satire. I loved it. The metadata was really for the benefit of those who believe that a shot like that would not be possible with that camera. There was no intent to offend you.

Now THIS is not satire.

My birthday is coming up. I keep dropping subtle hints like "I really want the 7DII!!!" but so far she has not picked up on it! :cry:

Meh. I don't even real know what it is but I know good photographs. Charts are not photographs they aren't worth much and they move no one. When I look at a lens I look for photographs made with that lens to see if I like the look it will render.

I agree :thumbup: :thumbup:
However, some here seem to feel the proof is not in the pudding, but in the pudding recipe. Or rather in one ingredient in the recipe. For instance in Chicken with Plumbs, I am sure they think the proof is in not the chicken or the plumbs but in the ¼ cup of water.

7DM2 16000 ISO

Maybe you would like to look at the metadata from that image. It plainly states that the camera is Canon EOS 7D Mark II.

Ever heard of satire?

Of course I believe it is from the 7DII. But reading other posts in other 7DII threads, there are those who MUST say it is impossible or their whole belief system is threatened.

live view focusing

Gene, do you think this is a good reason to buy more expensive glass from major companies like Nikon and Canon, i.e., better support. reliability, and ability to update and upgrade? I get the feeling that Sigma and Tamron do not provide the same level of support.

Have you had trouble with their support or are you just assuming?

Photo of an Owl in a tree shot with the 7DM2

NOT POSSIBLE!!!!

The camera only scored a 70 at DxO, so it is not possible that shot is from a 7DII!!!

The only thing that matters is the Sensor score!!!!

Actual pictures should not be used as evidence!!!

I know this because that is what Nikon users say!!!

New guidance on the right camera

Great, so you got the $999! Still the 70D for your husband would be nice, if it is in your budget.
