[QUOTE="algmiyazaki, post: 310558, member: 14248"] Thank you for your replies. I wasn't aware of that setting but it hasn't solved the issue. I did extensive testing today while out hiking. No settings on the camera have any effect on whether the flash triggers or not. Neither does the type of lens, the focal length, or whether or not it is macro. It appears to be related to lighting but my camera just isn't very good at detecting it. I noticed three things that affected whether or not it fired: -Lighting (seems weird, as sometimes it triggers in bright light) -Perspective (probably due to changes in lighting) -Distance from subject (also could be caused by lighting detection) I found patterns in its behavior while shooting damselflies. For example, the damselfly was on a rock. My focal length was set at 90mm (Tamron) or 40mm (Nikon). Changed lenses, f-stops, shutter speeds, menu settings, etc. and none of that determined if the flash fired or not. What DID happen was this: if I was shooting at a fixed distance, say 3 feet from the subject, and I changed this distance, it sometimes would stop firing (both getting closer AND farther away). When I went back to the distance I was at before, it would fire successfully. Another thing that happened: if I changed my perspective it would cease to fire. I found it fired the most if there was a solid, flat background, such as a rock or ground. If I shot directly above the rock it would go off BUT if I kneeled down so that I was shooting the rock from a side angle it wouldn't fire anymore. It wouldn't fire for flies that were sitting on branches, grass blades, flowers, etc. I just wish there were a way to get it to fire no matter what. Is my only option to buy external flash? (Will I be able to force that to go off 100% or will it still tie in to the camera? I've never used an external before.) [/QUOTE]
