First tests to do when receiving dSLR(searchig CAMERA CHART)

[5 Type]

Hi,

My father in law is receiving his 10D + 28-135 tonight. I am wondering what are the test to do, in order to be sure he has a good one. My guesses are :

Front/Back focus
Doing tests like the test done with the oranges in the other thread. Having the 10D focus with the center point.

Dead/Bad Pixels
- Should I be taking pictures of a White sheet of paper (this way I also make sure that there is no dust in.

- Should I be covering the lens with the lens cap, in order to have the picture complelely black.

Soft pictures
- I guess, if I can be able to find this kind of image :
http://www.dpreview.com/reviews/CanonEOS10D/Samples/Compared/4way/th_canon_eos10d.jpg
And taking picture of it full wide 28mm, full open f3.5 because it's the worst case scenario.

If you know where to find such image, please tell me.

Any other tests I don't know about?????

Take some pictures, but have fun doing it.

THEN if you think you might have an issue, go measurebate.

The 10D focus issue is highly overrated. As an example, a friend borrowed my macro lens and couldn't get anything in focus correctly. All his others lenses worked fine. I figured it was user error and took his camera overnight and ran some quick tests. The camera was fine - he just needed to practice taking macros.


But otherwise your tests seem fine. You might want to look for both Hot and Dead pixels, so do both, or here's a free Hot/Dead Pixel Test program: http://www.starzen.com/imaging/deadpixeltest.htm

I agree woth Scottes, have fun and just take pictures. I sold my D100 and lenses to make the decisive switch to the Canon 10D. In the beginning I got all tied up with testing--not because I saw a problem (I was pleased with the images)--but because I read too many posts on these forums. Just do what was already said above: have fun and then IF you SEE a problem investigate it. Oh, and one other thing, my early problems (I lied; I had a few) were due to user error. When you get the new camera, make absolutely sure you understand how the 10D selects a focus point and the ramnifications on exposure. And I also found--especially at larger aperatrues, leaving the camera in AI FOCUS mode works better for me; I guess I "sway" front-to-back (hihi). Regards, Dan.

Thanks guys.... I've done more research... And those two thing would be help full if anyone would be able to get a digital version of it.

13A/ISO DIGITAL CAMERA CHART
http://www.precisionopticalimaging.com/13A-ISO.jpg

Also known as PIMA/ISO Camera Resolution Chart. This chart conforms to ISO-12233 specification. Available in multiple sizes. Free software for image analysis is available on the web. See the link section.

IEEE RESOLUTION TARGET
http://www.precisionopticalimaging.com/IEEE.jpg

This chart was designed to conform to the IEEE standard STD-208-1955, measurement of resolution camera systems. This target can be used to check scanning linearity, aspect ratio shading and interlacing as well as resolution.

[Scottes]

Those are professional test targets made and printed to very exacting standards. I've seen stuff like that for about $80, though I have no idea how much either of these are.

But you don't need them anyway.

DONT do the dead pixel test! It will drive you MAD! MAD I say!

Why....? I guesss that I will see that even a new camera does have some.

You can choose between the following two approaches:

(1) Do all kinds of tests and be disappointed that your new digital camera is not perfect.

(2) Use your skills to make beautiful photographs and be amazed about how wonderful your new digital camera is.

:roll: :? :D

18,000 shots on my 10D and no test charts or rulers.. I once shot the edge of some jewel cases.. this was as far as I went with focus tests.. but that was only after I discovered I had a focus issue.. the issue was casused by a recently added UV filter.. no filter,. perfect test results..

My answer.. the only test to do on receipt of a new Camera is to go out and take some nice photos.

Aaaaaagghhh a potential measurbator.

Take said camera and go and take some picture with it/ If they are good, then the camera is good. The out of focus issue is overdiscussed though I must admit, if I knew I had it I would have to do something about it. Erto. Ignorance is bliss.

My 10D may well be out of focus. I dont car a flying fig. I love the picture it takes and would cry like a baby of it were to be taken away from me.

Enjoy it, dont analyse it.

I'm just taking those precautions because I have a 30 days exchange warranty. After that is normal warranty.

I've heard of photogs taking 13,000 pictures in 30 days.

Why are you reading this?

Because, when I got my new Rebel, I discovered that it has 1 hot pixel (I should have said hot pixel before) right off the bat at 1/30 second or slower. I debated and debated on sending it back (which would take 2 weeks), but then I did some reading that my chances are good that I will just get another camera with a hot pixel, or maybe even multiples.

I know of one person who had a hot pixel on his new Rebel, he took it back, tried 3 in the store, and all had atleast 1 hot pixel (a couple had 2 or more). In the end he kept his original camera.

I just did this with a 5 min exposure on my battered old second hand D60 and i had no dead, bad or problem pixels at all :D :D :D

Maybe more like "Why go looking for something that might not be there - if it is there, you'll see it anyway."

The only reason I asked the number of shots was so I can get an idea of a MTBF for the 10D. I am sitting near 3100 as I speak and think it might be around 3500 or more by the end of today (Sat 6th Mar). What are you sitting for # of pics, Jim? I can't say I have had a problem w/ focus since getting some L or Sigma EX glass.

I'm approaching 18K on the 10D.

[RichardtheSane]

Here's my take on this.

I bought my 10D a couple of months after the release. I got it, I enjoyed the extra latitude digital gave me, I joined a couple of forums and started interacting with other 10D users.

Ones with focus & exposure problems.

OK, there weren't many, but they were very loud about their problems. Being new to a DSLR I didn't realise how much more a difference your photography technique made to sharp images. I did some focus tests and because the tests are not really all that well explained then I had managed to convince myself that I had a focus problem.

Lucky for me, and with the help of some regulars who are still about today, suggestions were made about how I could improve my images instead of blaming every out of focus pic I had on a problem.

Needless to say my 10D was fine, but because I was looking for a problem that wasn't there I was ready to send it to Canon. Don't fall into the same trap.

Use the camera, and if you are not getting the results you expect then do a focus test.

Sage advice indeed...

Here's an update

The 10D is received...

My father in law decided not to do any tests I've provided to him... but he did the only real one : Taking it outside, and enjoying it. He loves it very much. And, at first sight, everything seems allright.

That's for your advices.
