PB-E2 max frame rate with EOS-3

greenspun.com : LUSENET : Canon EOS FAQ forum : One Thread

The eos-3 frame rate is 4.3 fps With the PB-E2 it shows 6 fps and with the PB-E2 and NP-E2 is 7 fps

If I use the PB-E2 with AA NiMH batteries why can't I get 7 fps? These should have the same voltage as the NP-E2.

I have read somewhere there is a button in the PB-E2 that you can force it to 7fps.

Can anyone confirm this? Anyone do this?

thanks

The PB-E2 with AA NiMH batteries do not have the same voltage output as the NP-E2. There is a small white button inside the back of the PB-E2 that sticks out when the normal battery pack is installed. You can put a small piece of tape over the matching cutout on the PB-E2 and this will enable the 7 fps speed. You will also notice that the BC flashes when this is enabled because the voltage is considered to be low as compared to the NP-E2 batteries. It does work if you need the extra speed but I have not used it that way other then trying it out.

I had the same idea and would try it. However, according to EOS-3 special catalogue in Japan, when PB-E2 detects low voltage of NP-E2 then the drive train will shift to that for lower speed. NP-E2 has 10 cells NiMH, namely output 12V in total, while AA NiMH x 8 output only 9.6V. So even if you make "a small white button" on, PB-E2 will not work stably at 7 fps speed. Very initial output of fully charged NiMH is over 1.4V (x8 is close to 12V, so PB-E2 may work at 7 fps for several shots) but very shortly it downs to 1.2V. "Lower speed" means 6 fps, thus you can hardly tell whether it works at 7 or 6 fps. There is no way other than you buying NP-E2 to get stable 7 fps on EOS-3, or 10 fps on EOS-1V HS.
