40D... mes désillusions (passagères)

[canon-passion]

pourquoi ne pas avoir laissé les données EXIF de la photo ?

les exifs sont bien présents.

Pour la une:

* Exposure Time (1 / Shutter Speed) = 1/640 second = 0.00156 second
* Lens F-Number/F-Stop = 56/10 = F5.6
* Exposure Program = aperture priority (3)
* ISO Speed Ratings = 400
* Exif Version = 0221
* Original Date/Time = 2008:05:18 18:46:58
* Digitization Date/Time = 2008:05:18 18:46:58
* Components Configuration = 0x01,0x02,0x03,0x00 / YCbCr
* Shutter Speed Value (APEX) = 614400/65536
Shutter Speed (Exposure Time) = 1/663.98 second
* Aperture Value (APEX) = 327680/65536
Aperture = F5.66
* Exposure Bias (EV) = 0/1 = 0
* Flash = Flash did not fire, compulsory flash mode
* Focal Length = 500/1 mm = 500 mm
* Last Modified Subsecond Time = 00
* Original Subsecond Time = 00
* Digitized Subsecond Time = 00
* FlashPix Version = 0100
* Colour Space = sRGB (1)
* Image Width = 602 pixels
* Image Height = 903 pixels
* Focal Plane X-Resolution = 3888000/876 = 4438.36
* Focal Plane Y-Resolution = 2592000/583 = 4445.97
* Focal Plane X/Y-Resolution Unit = inch (2)
* Custom Rendered = normal process (0)
* Exposure Mode = auto exposure (0)
* White Balance = manual (1)
* Scene Capture Type = standard (0)

Pour la deux:

Exif Sub IFD

* Exposure Time (1 / Shutter Speed) = 1/320 second = 0.00313 second
* Lens F-Number/F-Stop = 56/10 = F5.6
* Exposure Program = aperture priority (3)
* ISO Speed Ratings = 400
* Exif Version = 0221
* Original Date/Time = 2007:05:28 19:33:25
* Digitization Date/Time = 2007:05:28 19:33:25
* Components Configuration = 0x01,0x02,0x03,0x00 / YCbCr
* Shutter Speed Value (APEX) = 548864/65536
Shutter Speed (Exposure Time) = 1/331.99 second
* Aperture Value (APEX) = 327680/65536
Aperture = F5.66
* Exposure Bias (EV) = -1/3 = -0.33
* Flash = Flash did not fire, compulsory flash mode
* Focal Length = 500/1 mm = 500 mm
* FlashPix Version = 0100
* Colour Space = 65535
* Image Width = 600 pixels
* Image Height = 900 pixels
* Focal Plane X-Resolution = 4368000/1415 = 3086.93
* Focal Plane Y-Resolution = 2912000/942 = 3091.3
* Focal Plane X/Y-Resolution Unit = inch (2)
* Custom Rendered = normal process (0)
* Exposure Mode = auto exposure (0)
* White Balance = auto (0)
* Scene Capture Type = standard (0)

Pour revenir au sujet, si avec le 70/200 et l'objectif macro, c'est peut être bien un problème de compatibilité avec le 500.

je crois que pour être tout à fait sûr, il faudrait faire des testes sur mire et sur pied pour éviter toute suspicion du tremblement du photographe.
