Sigma Lens Reviews

I tried the Jeffrey'beds EXIF audience with three pictures used with the exact same camcorder (a Canon 50D) and three different lenses. The 'Internal Serial Amount' worth returned by was the same worth for all three images taken with the same video camera and three various lenses. Each image was used with, respectively, á Tamrón SP AP 17-50mmeters f/2.8 XR Di-II, an EF 70-200mmichael y/2.8 M Is certainly II, and an EF 28-135mm n/3.5-5.6 IS.

The two Cannon lenses had been correctly identified in the 'Zoom lens Model' field (The Tamron had been recognized as a 'Cannon EF 28-70mmeters y/2.8L or Sigma or Tamron Zoom lens' because numerous Tamron and Sigma lenses are known to spoof the lens Identification for the old EF 28-70mmichael f/2.8L). This network marketing leads me to believe the 'Internal Serial Amount' worth will be a benchmark to the camera body, not really the lens (at minimum on old Canon bodies that perform not distinguish between two various copies of the exact same lens design for different purposes such as AFMA). Actually though the the lens Identity instantly precedes the 'Internal Serial Number' value, it may not accurately reveal the serial number of the lens used to create the image. Images taken with my 7D making use of two different lenses provided the exact same 'Internal Serial Amount' with each some other, a various number than the three images taken with three lens using the 50D shared. Images taken with my 5D mark II have a blank 'Internal Serial Quantity' value when using Jeffrey's EXIF Viewers. Many Canon video camera bodies have got a different internal serial quantity that doesn't fit the one stamped on the external of the surveillance camera, at least not when the number in the EXIF will be translated making use of a regular hex to decimaI converter. This máy also be the case concerning lens Identity numbers with physiques that can distinguish between two various copies of the exact same design lens.

The value for 'Video camera Serial Number' in the EXIF manufacturer information of pictures taken with my Cannon 50D is certainly 5AA411141. Using a regular converter produces a decimal worth of 7. Yet the Serial amount placed on the surveillance camera body is usually. This quantity is properly reported by Digital Photo Professional as the camcorder's serial number. Irfanview reviews the serial quantity as ' (5AA411141)'. The HEX number that correlates tó the stamped seriaI quantity is '5AA42B85'. The very first four digits complement, but the relaxation doesn'capital t?

This is definitely very interesting, though, because (HEX) 2B85 = (Decimal) 11141! Hence it seems the inner amount in the EXIF details is a combination of hex and decimal digits! A four digit hex quantity (in my situation '5AA new4') followed by the decimal equivalent of the relaxation of the hex form of the whole serial quantity (in my case 11141 which is usually the decimal equal of 2B85)!

The Value for my 7D and 5D II function precisely the same method. If I convert the cameras's serial number to Hex, then convert the last four hex numbers back to decimal, I obtain the exact same worth that the machine notes display for the camcorder serial amount: The very first four digits of the 8-digit hex number adopted by the decimal comparative of the final four digits of the 8-digit hex number. Although it doesn't assist your situation, the greatest practice when promoting a lens anyplace near the worth of an EF 85mmeters f/1.2 T would be to document the serial amount of the Iens and the condition it can be in before you deliver it.
