Below is my old mail which might give some answers. Vesa ------- I was lucky enough to be able talk to a person who seems to know the EOS3 firmware versions and because I haven't seen this I thought you might be interested as well. At least for me everything is now clear (enough). I was previously suspicious when I read the messages in this forum: sometimes someone "knew" that FW 2.1 is the latest firmware and sometimes someone other had hear that there is no new firmware to fix the "underexposure problem". NOTE: Since I didn't write anything down I may remember some details wrong! - There are two SW components involved: 1) The Adjustment software (runs in a PC) 2) The camera FW (firmware) Adjustment SW: -------------- - The Adjustment SW is a tool which is used by camera service technician to adjust some settings manually. It also may make some settings/fixes in the camera automatically. I think CF19, power consumption problem with long teles and the exposure changes are done with this tool. - The version 2.1 (e.g. 2.1R or 2.1F or whatever) what some have mentioned to be FW version is actually version of this SW tool (running in a PC). - Once more: this program is not loaded in to the camera. Instead it is used to change some settings. Camera FW: ---------- - Also a new camera FW can be downloaded (in to the camera) but probably is not required to fix any of the above mentioned problems. - The current version number is 6E or something similar. Vesa BTW. I also had my EOS-3 (very early version) checked and I was told my camera was underexposing 0.5 stops at all EV checkpoints. When I asked more they said that *if* there is an underexposure problem it often is such that at EV 15 the exposure is fine but at the two(?) lower EVs which they use to check the exposure the error (-0.5 stops) is visible. The factory tolerance is half a stop (thus +-0.25 stops), I think. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.; * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
