Thanks for the reminder however! <br /><br />1/200th is about the max with the 5D. I've tested other cameras (1D series) with the Elinchrom Quadra (not Ranger) hooked up via Pocket Wizard FlexTT5 to achieve higher sync speeds (in the 1/800th range), but can't seem to achieve much higher than the standard with the 5D due to the larger sensor size. <br /><br />You can always use ND's on the lens if you're trying to achieve a wider aperture and shallow depth of field (I recommend the Tiffen IR ND series for least amount of contamination). <br /><br />I'll be back in NYC for PhotoPlus late October and will meet with the Pocket Wizard/Elinchrom folks to see if they've had any success on the larger sensor cameras. Stay tuned.<br /><br />-KevinKevin Winzeler Photographyhttps://www.blogger.com/profile/05900569945752370627noreply@blogger.comtag:blogger.com,1999:blog-2476814055216341502.post-51003285786446390322010-09-01T01:40:41.808-06:002010-09-01T01:40:41.808-06:00Hi Kevin,

I would like to know more about using my Ranger RX speed A over the sync speed of my 5DMKII, is there any tips to work faster than the 1/200th under the bright sun of New Caledonia island (where I leave) ? Thanks for sharing, I like your work man !<br /><br />cheers,<br />SebastienUnknownhttps://www.blogger.com/profile/08807365210964567212noreply@blogger.comtag:blogger.com,1999:blog-2476814055216341502.post-84265904120469346782010-06-02T08:52:31.185-06:002010-06-02T08:52:31.185-06:00Thanks for brining this up.

However, my white lighting and alien bees work like your rangers. <br /><br />I now am going to make a cheat sheet for each strobe. <br /><br />thanks again,<br />gradyFrozen Forever Photographyhttps://www.blogger.com/profile/01482972547636266410noreply@blogger.comtag:blogger.com,1999:blog-2476814055216341502.post-68149646354577849422010-06-01T11:45:51.424-06:002010-06-01T11:45:51.424-06:00@Grady-

The message is to check and know what your system does and/or before you buy to think about what you need and how the system you buy fits that need.Kevin Winzelerhttp://www.kevinwinzeler.comnoreply@blogger.comtag:blogger.com,1999:blog-2476814055216341502.post-57531312082437915682010-05-30T14:38:05.211-06:002010-05-30T14:38:05.211-06:00Hey Kevin,

However, I dont understand why the Rangers speed up as you increase power. Does this apply to most power pack set ups?<br /><br />Thanks,<br />GradyFrozen Forever Photographyhttps://www.blogger.com/profile/01482972547636266410noreply@blogger.comtag:blogger.com,1999:blog-2476814055216341502.post-62192590112203422372010-05-28T08:52:59.116-06:002010-05-28T08:52:59.116-06:00@Jase - I didn't talk about speed lights, but ...@Jase - I didn't talk about speed lights, but should have mentioned one thing: The flash duration of speed lights gets SLOWER as you INCREASE power. So an SB-800 or 580EXII at Full power has a longer flash duration (around 1/800th of a second). However, due to how speedlights cut off the light at lower power settings (shorter curve in the graph above), they have an incredibly fast flash duration as you decrease the power. This is one advantage of speed lights and why you see a ton of speed lights at lower power settings used for stuff like hummingbird photography, a water balloon bursting, or trying to stop a speeding bullet.<br /><br />580EX II - flash to sensor 1-3 feet roughly:<br /><br />Manual at 1/16 power = 1/15,000 second +/- 25%<br />Manual at 1/32 power = 1/19,000 second +/- 25%<br />Manual at 1/64 power = 1/31,000 second +/- 25%<br />Manual at 1/128 power = 1/35,000 second +/- 25%<br /><br />courtesy: http://www.waynesthisandthat.com/flashdurations.htmlKevin Winzelerhttp://www.kevinwinzeler.comnoreply@blogger.comtag:blogger.com,1999:blog-2476814055216341502.post-34548710777579198102010-05-28T03:09:37.193-06:002010-05-28T03:09:37.193-06:00Very useful article Kevin.
