Software & Accessories / Re: Lowepro Toploader 80/85 Pro AW
« on: April 23, 2013, 10:42:57 AM »
I like them, and use them all the time, but they are far from perfect.

I'm curious as to what you don't like about them (other than wanting a bigger one).  Personally, I'd like a pair of Sliplock attachments like the older version had vs. the one of the current versions, but other than that, they're pretty much ideal. 

For me, no need for a bigger version - the 75 AW holds a 1-series body with L-bracket and a large white zoom (28-300L, 70-200L II, 100-400L).  In fact, it holds my 1D X with the 100-400L and a 1.4xIII TC attached (so I suspect it would hold a 300/4L IS, too, but not with the TC).  The only need I could see for a bigger one would be to hold the 400/5.6 - but I don't have one and have no interest in getting one...

My RC-1 works fine with my 7D, only thing needed is to set it to timer/remote as above and point the RC-1 at the front of the camera.

But...but...but...their sensors suck. How can this be?!?!?!?!?!?  :o :o :o


It can be concealed in my hand (barely) when I'm in a shot.
Isn't that what the 3-second delay is for? Press button, slip remote into pocket / turn palm / whatever....

If it was just me, sure. But in a family portrait with multiple young kids, shooting several shots in relatively quick succession can help capture the kids' expressions, hopefully without those darn silly faces they think are funny...

Lenses / Re: 85mm f/1.2L II soft touch.

Any other Canon lenses have this finish?

None that I've used, besides the 85L II.

Mikael, you always seem eager to post DR scenarios which favor Nikon.  We know you have a D800, 5DII, and QPcard. Do you happen to have a light source with a constant, known color temperature? Actually, the packaging if a new bulb should indicate the temp in Kelvin units, and if you take shots one after another, it's constant enough.  Perhaps you'd be willing to shoot that QPcard with both cameras, and show us a straight-out-of-camera JPG with the WB set to the color temp stated on the bulb packaging?  Just a thought...

If everybody arguing past each other on this thread had started by reading that link, one might imagine a lot less sound and fury....

A vain hope, I'm afraid...   ::)

The Aion remote is big (5 inches long), fits in your hand nicely. But the smaller form factor of the Giga is enticing if you want something smaller in your hand. Note that Aion uses AAA batteries, while a remote like the Giga uses CR2 batteries.

The size of the remote was the main reason I picked the hähnel Giga T. It's 3.5" x 1.12" x 0.56", and it can be concealed in my hand (barely) when I'm in a shot (the Canon RC-1 is a lot smaller, though).  Incidentally, the receiver that attaches to the camera uses a CR2 battery, the transmitter uses a CR2032 button cell.

Lighting / Re: T3i - 600EX-RT or Canon Speedlite 580EX II
« on: April 22, 2013, 03:52:29 PM »
I don't think the Canon  ST-E3-RT will work on the Rebel.  The full advantages of this latest flash system can only be realised with the 5D Mark III or the 1Dx.  However, the 600EX-RT will work like the 580EX II with on camera flash & TTL metering etc. and wireless off camera flash through its line of sight light sensor.  It just won't have the radio capability with the OP's Rebel.

Think harder...or at least, smarter.  Although there are a couple of minor limitations to the functionality of the new RT system on pre-2012 bodies (lower Xsync, no group flash), most of the radio triggering functions work just fine.

Lenses / Re: Canon 100-400mm L EF mount alignment question

Mine mounts easily, like every other lens I own (and has done so on three different bodies).

Software & Accessories / Re: Screw-in variable ND filters
« on: April 22, 2013, 03:19:18 PM »
With what lenses will you be using the ND filter?  If you're shooting wider than 24mm (on FF), you'll get a 'Maltese cross' artifact (a black 'X' through the scene) that gets worse the wider the AoV and the darker you set the variND (effect derives from uneven polarization at wide angles, since a variND is stacked polarizers). 

I use a 10-stop and a 3-stop ND, as needed - I've avoided a variND for the above reason.  I also have the Lee holder for grad NDs.

The Canon 5D MK III works with cheap Canon infrared wireless releases, if all you need is shutter release, get one of those.

+1.  The reason I got the hähnel RF remote is that the 1D X can't be triggered by the little Canon RC-1 IR remote I have.

A remote shutter just releases the shutter.  A timer shutter lets you do timed shots, interval shots (time lapse), etc.

I've heard of 1 and 3. Personally, I use a hähnel Giga T Pro II - timer release that can work wired or wirelessly.

Software & Accessories / Re: Markins L-bracket for Canon EOS600D
« on: April 22, 2013, 10:58:40 AM »
Check Really Right Stuff or Kirk. I'd take one of their custom fit L-brackets over a universal bracket, any day of the week.

I missed that it was video
make a real WB against a qp-card

Does it make sense that setting an identical Kelvin color temperature on different bodies would give different results?

yes it does, because of the cameras  CFA, algorithm etc and  the light , different cameras response different to old or new light sources and Kelvin  , therefore it is always best to WB against a well known surface in the light you are in and   as for example a qp-card

Makes sense, thanks.

If these snaps of the rear LCD are representative of the actual output video, however, I'd have to assume something is wrong with this D7100.

Even if they're not representative of the actual output, I'd still say it's a problem, although not as bad.
