I'm betting on the II's combo.

Perhaps - but, juggling two lenses (24-105 + 70-200 II) on outings with two toddlers is why I got the 28-300mm in the first place...

Still have my 28-300mm, IQ is similar to the 24-105mm.  May still sell it at some point, but I got it quite cheap (used) so that's not an issue - would likely fetch a profit.  Going to see how it does on the 1D X first, and since I'll likely pick up a 24-70 II, I'll evaluate at that point the tradeoff between the convenience of the 28-300 vs the IQ of the 24-70 II + 70-200 II.

Mt. Spokane has/had a 35-350L, IIRC he liked it. I know he's posted pics from that lens in a few threads previously. Perhaps he'll chime in...

thats the one I just got from them after mr revup so kindly recommended them to me

Which was after I recommended them to him...   :D

Also, there's no coated version for the 82mm diameter, although smaller sizes are available in either single coated or with the MRC coating. 

Actually, there is no B+W 82mm 10-stop ND filter anymore, although there was, years ago.  Even though the one avialbable now is listed as a B+W filter, unlike the other #110 filters which are actually B+W-branded, the 82mm is a Schneider Optics-branded filter.  Schneider is the parent company of B+W, and they make excellent filters, but mostly for the TV/motion picture industry; for example, they're the only maker of glass rectangular grad ND filters, everyone else uses resin).  Before this filter was available, I inquired of Schneider/B+W if they would be making it again, and was told they were considering doing so in the Schnieder line - about 9 months later, it came out.  Paul at Schneider Optics' US office kindly gave me a heads-up, and I ordered as soon as it was available.

Here's a visual comparison:

I won't have time to get the SR-NR before the happening, but I will get one finally. I thought that the LC-5 might not work due to the angle. The only option left to me as I see it is to get this Phottix trigger

Then I can stand with my mk II and my 70-200 and shoot him as he is approching the bend, and as he is speeding away again, and then trigger the other camera with the phottix with my left hand:)

I guess I wasn't clear - as long as it's the 5DIII you want to trigger remotely, you can do that right now, without buying anything.  Mount the ST-E3 on the 5DIII hotshoe, and you can radio trigger the shutter with the 600EX-RT.  See p. 68 of the 600EX-RT manual and/or p. 42 of the ST-E3 manual.  Granted, the 600EX-RT isn't the most convenient remote control to hold, but it's one you already own.

The cable would only be needed if you wanted to trigger the 5DII, or wanted to have both cameras capture an image simultaneously when you press the shutter button of only one (can't do that with the Phottix, AFAIK).

First of all the ST-E3 is a Speedlite Transmitter, so nothing can be received with it.  Second, the 600EX-RT (or any Canon Speedlite for that matter) cannot trigger the camera to fire (out of the box, at least).

Wow - two wrongs there, and unfortunately, they don't make a right.

The 5DIII and 1D X can be triggered by a 600EX-RT mounted on the hotshoe, from another 600EX-RT connected as a slave unit.  Pre-2012 camera bodies need the Release Cable SR-N3 to connect the 600EX-RT to the remote terminal for triggering. 

An ST-E3 on-camera can also trigger a 5DIII or 1D X shutter from a 600EX-RT connected as a slave (meaning, yes, the ST-E3 can receive radio signals, too).  Again, the -N3 cable is needed for older cameras to connect the ST-E3 to the remote terminal.

Is it possible for me to shoot with my 5D II with an 600 EX RT, and to trigger at the same time the 5D III which stands on a tripod at the same time? If so, does anyone know how to?

You can't trigger the 5DIII by firing the 600EX-RT on the 5DII, though.  You can manually activate the release from the 600EX RT to trigger the 5DIII with the ST-E3 on it.  Check the "Remote Release from a Slave Unit" section of the manuals.

With additional hardware, you could trigger both cameras simultaneously - in fact, you can link up to 16 cameras together for simultaneous shooting, if you have enough ST-E3s/600EX-RTs). 

If you can get a hold of a Release Cable SR-N3, what you could do would be to connect that to the 5DII's remote terminal, then set up Linked Shot mode, with the roadside camera as Slave and the distant camera as Master (either camera would work for either, AFAIK).  Then, the pressing the shutter release on the Master would trigger both cameras to fire at the same time.

From looking online, it appears that Adorama has the Release Cable SR-N3 in stock.

The display brightness is altered based on ambient light, and it's a bit slow to update.  It might be that when the review image first appears, the ambient light at the back of the camera (where the sensor is) was lower because the camera was held to your face, but when you later press play it's getting the correct reading.

1DX only uses the two digi 5+ for speed the digic iv has nothing to do with the throughput it is only used to drive the fancy new metering chip and the color/face tracking mode assist for phase detected AF.

Hmmmm....then why is the Digic 4 chip in there at all?  Most likely, it's there because if the dual Digic 5+' had to handle the metering, the camera could not achieve 12/14 fps.  So it may have a lot to do with the throughput, albeit indirectly.

I enjoy watching this kind of fight

Since you're so fond of watching Amazon's Top 100 Best Selling dSLR list, I wonder if you've looked at their Top 100 Rated list

Canon has the top 8 positions on that list, 17 of the top 20 slots - you have to go all the way down to #19 to find the first Nikon camera on the list.  Still, it sould make you happy that even there, the D800 is ahead of the 5DIII...  ::)

...i think this will be very well matched with a mirrorless... 

I don't think any EF lens is a good match for mirrorless - one reason mirrorless bodies are so small is that the lack of a mirror means a much shorter flange-to-focal-plane distance is possible.  So, while I'm sure it will be possible to mount this lens on a hypothetical future Canon mirrorless body, via an adapter, the result will be bigger than a lens designed for such a camera.

Could an omnibounce for the 580ex2 fit the 600ex? Perhaps all it needs is to cut out a notch for the gel sensor?

I don't think so - I believe the shapes are different enough to prevent a fit.

Actually it would've been lovely! If it allowed 7fps as some of the crazy rumors said (per some Australia Canon rep) then I actually would be getting a grip (for the times seriously shooting sports).

The point is, Nikon's 'requirement' for the grip to allow the higher frame rate is a completely artificial limitation in the firmware - you can hack their cameras such that the higher frame rate is achieved without the grip, ergo, Nikon is restricting that feature merely to force users to pay more for another product.  Canon allows the camera to shoot at it's maximum frame rate without any add-on.
I mean, it's not like Canon would ever impose an artificial limitation on a camera model via firmware like that.  Never, ever.  Not even once.

Please help me feel better about owning f/4.0 L Zooms.

Canon's f/4 zooms are excellent!  If you need to stop action in low light and require the flexibility of a zoom, the f/2.8 is a better choice.  If you're going to use the 70-200mm for portraits, again the f/2.8 would be a better choice.  But for most applications, the f/4 is just fine, and is much easier on the arms and wallet.

The question remains as to whether the mark II lens could possibly be updated ENOUGH to warrant that much of a price increase.  I mean, how can you improve IQ that much over a lens that already performs very well?  This must be some sort of "super lens."

No doubt about it.  The current (now discontinued) 24-70mm is a good lens, but it has focus shift, and while the color and contrast are excellent, the sharpness is just good.  If you compare the 24-70mm to several primes in the same range, the primes have better IQ.  If you do the same comparison with the new 70-200mm II, you find that it equals most primes in that range - if the new 24-70mm II is the same, it's more than worth the price increase (to me, at least).

Speedlites, Printers, Accessories / Sto-Fen OmniBounce for 600EX-RT
« on: May 22, 2012, 10:09:57 AM »
Got the new Sto-Fen OmniBounce for the 600EX-RT last week (ordered from Adorama, now B&H has them, too).  Fit is very snug - tighter than the ones for the 430EX II. There were early reports that the older one for the 550EX would fit, but I wondered about the gel sensor.  On the one for the 600EX-RT, there's a little notch for the gel sensor. 

The flash with the Sto-Fen mounted is too large for the Canon pouch (barely - the velcro closure still overlaps by a couple of millimeters), but it's a perfect fit in the Lowepro Quick Flex Pouch 75 AW.
