NOTE: Following further research and reliable information received this page has been totally re-written.
INTRODUCTION:
Have you ever wondered how some people can quote the number of shutter actuations their E-system camera has done from new? Yes, me too! Well here's the answer. You may already know how to do this, so forgive me if that's the case. For any of you who don't know how to access this information and more - read on!
It's quite simple but you won't find it any any Olympus Handbook. The procedure is good for all E-System cameras (but please see 4. immediately below for the correct buttons sequence to access the camera designation screen). It also worked with my Mini Mju S.
The screenshots below are from my E-1, taken with an E-330.
PROCEDURE:
WARNING - At your own risk - I've done this without problem, as have many others; but still..........
1. With a working and charged battery installed switch the camera ON.
2. Open the card door.
3. You will see the warning CARD COVER OPEN icon in red on your screen thus:
Screen 1. Open card door warning.
4. Press DISPLAY & OK buttons together for E-1 and E-500; for E-330, E-400 and E-3 it is MENU & OK.
5. You will see the Camera Designation (Top Left of screen) thus:
Camera Designation screen.
6. Press the following buttons in sequence: ARROW PAD up, down, left, right; then press the shutter button; then press the up button on the arrow pad. If nothing happens close the card door, wait a couple of seconds and re-open it and try again. Press the buttons firmly and hold them in for about a second. Press the shutter button well in.
7. You will see Page 1 displayed. You can scroll through the 4 available pages by pressing the arrow pad keys.
8. To revert back to normal operation simply close the card door.
WHAT'S IT ALL MEAN?
The image below is a composite of the four screens you see on the E-1. The information that follows is accurate.
These are the four E-1 service screens accessed by pressing the 4-way arrow buttons; pages 1, 2, 3 & D:
PAGE 1 *² :
MU: Main (User) CPU: DC2 User Area *³
MB: Main CPU: DC2 Boot Area
M3: Main CPU: DSC23
SL: CISC
L: Lens CPU *¹
F: Flash CPU *¹
*¹ It is not a lens/flash model identity function, it is the firmware version. Most lenses are at a different level of firmware. Public firmware versions are numbered 1.0, 1.1, etc. Real firmware version is four digits hence 1004 appears as 1.0 on the initial firmware display and 1102 appears as 1.1.
*² It's been confirmed that all of 'page one' are firmware versions, the main camera firmware being top of the list.
*³ MU or U position on list is camera dependent; eg it is listed second on E-300.
NB: The first letter of two letter codes is deleted in other cameras; MU = U; MB = B etc.
PAGE 2:
R: Shutter RELEASES (number of)
S: FLASH fires (number of)
M: SENSOR cleaning (number of times mirror locked up for sensor cleaning by user is counted because it is risky!)
U: USF (Ultra Sonic Filter) number of times it is driven by user and by automatic control of the camera is counted.
V: V (If present) counts two operations: [i] number of times the mirror has been locked up in Live View, and [ii] number of times the AEL button has been used to auto focus while in Live View
PAGE 3:
CS: Serial Number; this should match the serial number on the bottom of the camera ************ but doesn't on some repaired models*.
MCS: Main CPU Serial Number, Model No, Year and Month of manufacture.
The first four digits of the MCS number are the model code of the camera:-
E-1 = 4001
E-300 = 4007
E-500 = 4011
E-330 = 4016
E-510 = 4046
E-520 = 4067 - thanks to Jonas Hajek
E-400 = 4023
E-410 = 4038 - thanks to Michiel van Dijk
E-420 = 4060
E-450 = 4060 - thanks also to Jonas Hajek (coincidence the 450 is same model code as 420?)
E-30 = 4073 - thanks to Miguel de No, from Spain
E-3 = 4031
E-620 = 4080
The next digit is the year it was built. The next two digits are the month of the year it was built. For example "710" indicates October 2007. * Thanks to Joe R in Florida.
NOTE: I have two E-1's, one bought in UK serial number 5000118XX that displays the MCS code (4001)310 - October 2003; the other was sourced from US serial number 140081XX that displays the MCS code (4001)310 - also October 2003. Please note the different enumeration of the serial numbers, presumably for different continents.
My attention has been drawn to some recent posts on DP Review that call into question the accuracy of this page. This page has been scrutinized by an Olympus technician well versed in the codes and their meanings. While he amended one or two previous errors he made no comment on the date coding. Please make sure you read the correct line on page 3 - the MCS line. The three figures immediately after 4001 (for E-1) will indicate the year and month the camera was built. If you have a MCS line that cannot be interpreted please email me the details so I can investigate further. This will be more constructive for the whole Olympus community than simply endeavouring to trash the accuracy of the information posted here. You can email me here.
CAMID: CAM-PCA Serial Number
PAGE 4:
D: Damage Codes
NB: These codes are recorded in 4 digit hexadecimal x 5 occasions; latest occurrence assumes top position. Clear by pressing OK (not advised)
Olympus technicians look here to see what error(s) the camera has recorded.
OTHER OLYMPUS DSLR's
Some of the screens change from model to model so this requires some interpretation by the examiner. I only have true information about E-1 service screens although it is assumed others will follow the basic format.
Here are the four service screens you will see on the E-500.
The E-330 is the same as E-500 except Screen 2 sequence is R S C U V L
The E-400 is the same as the E-500 except Screen 1 where the sequence is B U C A L F M
The E-3 has the same Screen 1 as the E-400
The E-3 has a different Screen 2 with this sequence: R S C U V B L.
READERS NOTES:
NOTE 1: A reader pointed out that E-1 counters are re-set when firmware is upgraded or when camera is returned for service. Thanks Dane. My own recent observations are different. In April 2006 I upgraded an E-1 from version 1.0 to 1.4 and noted with interest that the counters on page 2 where maintained. This particular E-1 (US sourced) was new in 2004 but had been virtually unused showing shutter actuation count of less than 400 before upgrading.
