K-70 and external intervalometer

CraigWA · 08-30-2020, 07:59 PM

Hello,
Camera: K-70
Mode: B
Exp: 10”
F: 2.8
ISO: 100
Intervalometer: JJC TM Series
DE: 2”
BU: 15”
INT: 18”
N: 4
Trial 1: Bulb replaces 10” in vari-angle monitor
Output: 2 photos each 17.9” exposure
Remarks: instead of 4 photos each 15” long; I get 2 photos each 17.9” long
Trial 2: Bulb does NOT replace 10” in vari-angle monitor
Output: 4 photos each 10” long
Remarks: correct number of photos, incorrect exposure
Must be a camera setting?

Try de-activating the noise reduction features for long exposure and high ISO, p.25 in the manual. Chances are the camera is taking too long to process each image so isn't ready for the intervalometer in time.

Thanks kypfer,

Problem solved by: 1) making sure all noise reduction: OFF; 2) GPS: OFF; 3) 7 Bulb (B) Mode Option: changed from 2 to 1 (this option is found in Menu C 1).

Yep...interval must be shorter than the time to expose + time for camera to return to "standby" state.
