How do you test your new camera body?

There have been a flurry of posts since the Mk3's hit people's hands of either problems or soft images. Until reading these posts I would have never thought of checking a sensor for dead pixels by shooting images with the lens cap on.

So I wanted to ask, in what ways do you test a new camera body for functionality? Any other checks you routinely perform like the dead pixel test above? Do you always do an AFMA with each lens in a closed environment?

Before concluding there are dead pixels, be sure the sensor is clean, as a speck of dust can look just like a dead pixel. A brand new camera shouldn't have dirt/dust on the sensor, but it could happen. Cleaning up a dirty sensor is relatively easy, whereas dealing with a truly dead pixel is a much more serious issue.

I use LensAlign MkII for AFMA, but it is a tedious process that requires careful setup and patience. Prime lenses are easier to do than zooms, as most cameras host only one AFMA setting. The new 1DX and 5D3 have separate W (wide) and T (tele) settings that supposedly improve the overall calibration at intermediate focal lengths. I'm due to get my 5D3 on 4/2 and will be testing out my new 24-105 as well as my EF 70-300 DO lens.

Thanks for the reply! I'll have to look into LensAlign. I was looking at a program called FoCal which helps automate AFMA. Looked neat and possibly a project worth supporting too. I'll add LensAlign to the list.

Received used (!?) 5D III from Crutchfield

No, no, no, $7 is for return shipping (I edited my post). $7 is no a big deal anyway, and Crutchfield rep agreed to waive it when I asked. I guess I am used to retailers paying for return shipping if there issue with the merchandise (like e.g. Adorama did without asking).

So Crutchfield was cool about it and they are OK in my book customer service wise. They generally have an excellent reputation in customer service department. Perhaps someone in warehouse screwed up and dropped the box. Please do not misinterpret my post.

Except the beat up box I do not have solid evidence of use. I should have reformatted the card in the PC before inserting it to the camera.

As for being over cautions. Perhaps. But I am not making up these things. Below is an example picture from camera #1 with defective shutter.

Converting from Canon to Sony - Lense equivalents.

Don't buy into the hype.

I bought a A55 when they first came out with a 24-70 and 70-400. I'm so much happier with the Canon lens selection, the old-school mirror, etc. The Sonys overheat, take terrible high ISO images, don't take in as much light, have a mediocre lens selection (mostly rebadged Minolta lenses), have mediocre accessories, etc. I wrote a long post on DPreview about my experiences that the Sony fanboys hated and helped to delete.

If you're going to buy Sony, buy a NEX.

I looked at the Nex 5n and fount it had no viewfinder. The Nex 7 has a EVF that looks like it might breakoff, but seems like a good camera, just overpriced. No really wide lenses either, 16mm (24mm equiv) being the widest..

As to lenses for a A57, you can, I believe pick from a big selection of Minolta AF lenses as well as the Sony.

there are tests of a limited number of Sony lenses here.

5D Mk III - No Problems (official thread)

To be honest, the IQ is negligible over my 5D2. Although all I ever really wanted out of my 5D2 was better AF, Slightly faster frame rate, and a dual card slot. So I cant complain. More testing still needs to be done. And a good side by side with the D800. Ill give a more complete review when I put it through the paces at my wedding. Ive found wedding photography to be a good testing ground :)

Isn't "testing" at a wedding a bit risky?

brave man! I'm waiting unitl i've fully tested everything before i shoot any critical work with it.

Anybody get 5dmk3 from abesofmaine?

i would go with adorama or b&h to avoid being pre charged, i know many were charged ealry march for the pre order of the 5dmk3.

This seems to be an ongoing issue with them, i would cancel and ask for a full refund, its not like they are authorizing the charge but not actually tying up credit, i would call your credit card company and let them know as well. They are collecting interest, while it may not seem like much, 3k plus on 5 customers gives them 15,000 in the bank collecting interest enabling them to buy and sell more.

Post your C1, C2, C3 settings

I adjust it on location but usually this is a combination of adjustments for specific shooting modes but they differ on what currently is being shot.

Generally when on event, including white balance on grey even while shooting all in RAW:
1. With flash - ISO max 200, just enough shutter to freeze action allowing as much backgrund light as possible, F5.6-8
2. Without flash - ISO max 800, no less than 1/30s, usually 1/longest focal on most prospectly used lens, F4-8
3. Without flash - ISO max 800, f fastest + for most used lens

When on action, sport, wild shooting - 1 becomes fast shutter, 2 - "situation shooting ready" around the scene
Video used mostly with magic lantern with it's custom settings.

Canon 5DMarkIII or Panasonic GH2 for video use???

The GH2 has the great, true 1000 lines of resolution that the 5D3 should have, but that has been crippled.

SUCKS on the part of Canon to do that especially since the 5D3 costs 3.5x as much.

With that said, Canon's colors are much better and the GH2 has a 2x crop so Canon has much more control over the DOF, which are huge factors. And the Full frame has much better low light than the m43 format.
