mervyn_wilmington Posted January 13, 2017 Share Posted January 13, 2017 <p>I use my XT1 with a Nissin i40. I often use bounce flash. It works very well, but sometimes can be a bit short of power and has longer recharge times.</p> <p>I was considering using another, remote, flash gun with a slave unit - I already have a slave unit. However, might it be the case that using the Nissin set to ttl, and perhaps other settings, that pre-flash would set-off the remote too early? Also any views on a 'cheap' gun for the slave?</p> <p>Advice would be appreciated.</p> Link to comment Share on other sites More sharing options...
steve_solomon2 Posted January 13, 2017 Share Posted January 13, 2017 <p>Hi Mervyn.<br> I had the exact same issue, until Iswitched batteries to VARTA High Energy AA's. Probelm solved! (I'm no electrical engineer, but I think the issue is that generic AA's don't have enough power to recycle the flash properly.) Good luck sir! </p> Link to comment Share on other sites More sharing options...
mervyn_wilmington Posted January 13, 2017 Author Share Posted January 13, 2017 <p>Thanks for that Steve. I always use top quality batteries. However, while I can see that such - including Vartas , which I have used in other sizes - might improve recharge speed, do they improve the actual flash output? I would have thought not, but someone may correct me.</p> Link to comment Share on other sites More sharing options...
steve_solomon2 Posted January 13, 2017 Share Posted January 13, 2017 <p>You're quite welcome sir. As for improving flash output, I haven't measured that, but my hunch is you're correct. I only noticed that the VARTA's resolved the issue where the flash occassionally <em>partially exposed</em> the frame. Once the flash is permitted to fully recharge though, I would <em>think</em> that any AA brand would work, i.e., provide the same power output (assuming no problems with the flash unit itself). </p> Link to comment Share on other sites More sharing options...
mukul_dube Posted January 14, 2017 Share Posted January 14, 2017 <p>Many cameras and flash-guns can have the pre-flash disabled. Some slave units can also be set to ignore the pre-flash. The manuals for the XT1 and the Nissin should show you the way. For combining the outputs of two flash-guns you might try manual mode rather than TTL.</p> Link to comment Share on other sites More sharing options...
