Bench Marking Your DSLR

[donbga]

Recently there have been discussions about the merits of one DSLR or another. DXO Labs has recently created a new website that will objectively allow comparisons of one digital camera next to others.

g'day Don

why?

g'day Don

why?

Ray,

The answer to your question is implied in my original post.

Don,

What are you implying? Are you saying that the new website at DXO Labs will allow one to objectively allow comparisons of one digital camera next to others?

If that is what you meant to say, I am confused because it seemed to me that was what you said the first time.

Yes, uh I mean I don't know. I'm sure I'm not sure now.

Assuming that the testing is good the site should be very valuable. Thanks for posting it.

"Bench Marking Your DSLR"

without getting into a definitions argument, doesn't "Bench Marking" mean comparing an example to a predertermined measure of quality and doesn't "Your" refer to an item belonging to me?

so, no Don, my question stands, why?

why would i want to compare my camera, which i am completely happy with, to someone else's measure of quality?

why would i need to compare my camera with another?

 

[Kerik]

These are only questions you can answer for yourself, grasshopper.

How about just not going to the website rather than conjuring up a useless argument?

 

[ann]

perhaps it would be a good site to review if one wasn't sure which camera to purchase?
before rather than after the fact.

Ann,

I'm sorry but I just have to disagree with you - that makes too much sense and cents!

Ann,

Would you please explain why?

Sandy

[ann]

just because!

Hi,

Interesting, but is it just me, or is there one HUGE omission in the description of this whole test setup:

WHAT LENSES DO THEY USE??? :confused:

Unless they use top-notch / best performing prime lenses of each brand, the whole comparison and focus on controlling testing conditions is just useless...

I all to often see tests in photographic magazines of good cameras with crappy "kit" type lenses... I never understand why they do it. Why don't they use top-quality lenses? OK, you buy the kit with the crap lens, but do we really want to know the performance of such a combination, or the real capabilities of the camera in combination with a high quality lens?... I know what I want...

I find it completely baffling that they say nothing at all about the lenses they are using...

shh, quiet Marco, you can't question the veracity of something like this, well not without being ridiculed

 

[ann]

no, that question makes perfect sense.

Most folks on the site are more knowledge and that would be the most logical direction for review. However, the beginning buyer may not even think to question the issues of lens quality. It would never cross my mind to purchase a "kit lens" as i am willing to pay the cost to get the results i want.

Altho, i would still consider sending my students to that site to review some basic cameras. I get questions all the time about what should i do, etc......

 

[Marco B]

shh, quiet Marco, you can't question the veracity of something like this, well not without being ridiculed

I don't mind at all being ridiculed, as long as I learn from it

But OK, they say "something" about this issue, that is, they test "noise" levels WITHOUT a lens attached to the camera body. But that still leaves questions about the other tests, I certainly see some lenses in other pictures...

 

[Ray Heath]

g'day Marco

i'd also question the value of comparing cameras

i make no claim to understand any of what is on that site but i did attempt to read one of the articles comparing the final amount of noise present in a print from a top pro camera and a lower level camera, it kind of made sense that the higher resolution of the pro camera leads to lower magnification of noise, i think that's what it meant

anyway, i did a google search to get an idea of the cost comparison between a pro and a consumer DSLR, the EOS 1D Mark III (i think this is the one in the article) costs more than 12.5 times the cost of an EOS 450D

i would like to know is it, or indeed how can it be, more than 12.5 times "better"?

Ray and Marko,

If you bother to take the time to read through the dxomark.com Q&A section all of these questions are addressed.

The technology developed by DxO Optics is globally accepted as the industry leader in measuring image quality. That technology is licensed and used by companies and organizations such as Kodak, Olympus, and NASA. If their findings aren't adequate or acceptable for your own use and questions then I suppose no information source will be.

that's not what we are questioning

Don

as stated i read some of it, and i question the value of it for most of us

we all know a super dooper pro camera with a full size sensor is "better" than a prosumer 10mP model, so what, most us have to buy what we can afford and make the best of it's capabilities

any thinking photographer knows there is always something better/bigger/newer/whatever

you have yet to seriously address any of my questions, apparently the best you and your friends can do is belittle, hence the misspelt comment

Ray,

If you will take the time to read the material at dxomark.com your questions will be answered. In the context of your original post you questioned the veracity and relevance of the information at dxomark.com. I don't understand what your resistance is to reading the information there.

Your questions seem to have the intent of being rhetorical with the hope of eliciting an escalatory response from the readers of this thread. Why is that Ray? As long as you make these kinds of posts I won't take them seriously and chide you for doing so.

so the great Don can't be questioned?

escalatory?

i was hoping to provoke a discussion on the merits and value, or lack there of, in the information, often unverified and misleading, offered by these websites

apparently i can't you seriously, pity

 

[sanking]

Don merely provided a link to a website that offers comparisons of digital cameras. There may be mistakes in the data or flaws in the methodology. If you find any please feel free to bring them to this list for discussion.

I would personally look at a wide range of information before making a decision about spending several hundred or several thousand dollars on a camera. It seems to me that we should welcome a site that has as its goal an objective comparison of digital cameras rather than waste time with a bunch of existential questions about the "why" that might better be left to philosophers.

From a personal perspective I am strongly considering purchase this year or next of a DSLR and welcome every bit of valid information I can get on the subject to guide me on how to best spend my hard earned money.
