The Broncolor Siros L doesn't do TTL. But, it would make sense for their trigger to, at the very least, pass the TTL signals on to its hotshoe since their trigger will be mounted on a TTL camera.

I have the RFS 2.2C and wasn't using TTL mode. The RFS 2.2C isn't able to pass the E-TTL signal from to camera to its hotshoe according the Broncolor which I found odd at the time. It merely passes the basic trigger signal. Maybe I'm doing something wrong and will try this again.

I've got a Broncolor RFS 2.2 trigger which has a hotshoe. But, when you attach an ST-E3-RT to it, it loses its ability to make adjustments to the speedlights.

Hi All, I've got a pair of monolights trigged by their own proprietary trigger (A) and a pair of Canon speedlites triggered by an ST-E3-RT. Trigger A is equipped with a hot shoe. But, when I attach the ST-E3-RT to it, the ST-E3-RT loses all ability to control and adjust the Canon speedlite features beyond merely triggering them. Basically, it becomes a basic trigger. I'd like to be able to fully control and adjust the speedlites from camera position. Can anyone suggest a dual hot shoe extender where I can attach both triggers and have the ST-E3-RT think it's attached directly to a Canon hot shoe? Thanks!!

Hi All, I have a Profoto 5' RFi Octa that I'm looking for a grid for. Now, I know Profoto makes one. But, the price of their grid is almost double that of the octa :eek:! Does anyone know of a third party offering that will fit the octa and my wallet? Thanks!

Sadly, there is no proportionality built in. But, the other features it offers make up for it. Hopefully, the additions can be handled by firmware updates.

Hi All, Is it possible to control the output level of the Siros L modelling light? I'm wonder if this is just one of those hidden gems as it doesn't seem to be mentioned in the literature. Thanks!

Marcus, What better option have you found? I was looking at Sigma's 50mm. It costs almost 3 times as much. But, I've read that they're inconsistent in AF.

<p>Bob,<br> You should see my face while watching that video! Like a deer caught in headlights.</p> <p>Robin,<br> There's a <strong><a href="http://www.canonrumors.com/new-50mm-on-coming-soon-cr2/">rumor</a></strong> that a successor might be announced "soon". </p> <p>Thanks for your responses. I'll send the lens in.</p>

<p>Hi All,<br> <br />I have a Canon 50mm f/1.4 which I bought roughly nine years ago. I purchased it along with a 5D. I just bought a 5D Mk III a couple of months ago and the lens worked fine with the new body. Recently, the lens stopped auto-focusing. I made sure it was correctly attached to the body and that the focusing switch was set to auto. Yet half pressing the shutter or pressing the auto focus button on the body does nothing. All my other lenses work just fine. Is there an issue with this lens body combo or is it just the lens. Anyone else have this problem?</p> <p>Thanks</p>

<p>Hi All,<br />I just got an Einstein 640 from Paul Buff and like it so far. I also got a Pocketwizard TT1 Mini and a PowerMC2 to control it. I was experimenting with Hypersync with a Canon 5D and the results were pretty good banding wise. There was one oddity, though, that I can't figure out. Shooting at full power and shutter speeds around 1/1000 sec, the photo takes on a blue cast: as if I were shooting with a Tungtun white balance. I verified that I was using a flash white balance. Increasing shutter speeds to 1/2000, 1/4000 and, finally, 1/8000, all's well: no blue cast. Decreasing the speeds below 1/1000, again, produce no blue cast. I did some digging and found that this could be caused by catching the front or tail end of the flash pulse (<strong><a href="https://www.flickr.com/groups/71917374@N00/discuss/72157631225174690/">link</a></strong> - 103Antares post near bottom). My question is, does this mean that there are shutter speeds that can't be used in Hypersync? It's not a biggie I guess. Just curious.</p>

<p>Bob,<br> Thanks for the tip! That's quite a bit there. My mind is sufficiently blown (not too hard to do, LOL) but intrigued. I guess I'm trying to put what your saying to field use. I think I'll take bone up on midtone and memory functionality and take some time this weekend to go out and try what you're suggesting. That should clear the cobwebs. I'll be back with questions for sure.</p>

<p>Rodeo,<br> My Canon 5D (original) fits that bill at 1/200sec. It's a good thing that speed was included. I wouldn't have been able to keep the configuration I wanted and be able to use that speed otherwise.</p>

BeBu, That's perfect! Thanks!

<p>Bebu,<br> In flash measuring mode, as I increase the shutter speed, I expected it to increase beyond 1/1000. Getting 1/75, 1/80, /190, etc is puzzling. Also, if I change the increments of shutter speed to thirds, I lose the full stop aperature + tenths readout.</p>
