At least only one of us 'idiots' on this forum doesn't know the difference between a lens and a camera, dilbert.

Software & Accessories / Re: Screw-on ND filter for 16-35 II

You shouldn't see additional vignetting with the F-Pro mount on the 16-35L II.

Normally at low power, the flash only partially discharges and can keep on going even while its recharging.

IIRC, that's controlled by a C.Fn on the flash. I wonder if being an RT slave affects that?  Another function has the slaves report back when recharged, and the master beeps when all slaves have reported - maybe that forces a wait until all slaves are charged, so turning it off may help.

PowerShot S100, and if I needed to replace it, I'd get a Sony RX-100.

Lenses / Re: 70-200 f2.8 MkI & Mk II and Extenders
« on: April 26, 2013, 11:30:28 AM »
70-200/2.8 MkI doesn't take extenders well.  MkII takes the 2xII/III well, almost but not quite up to the IQ of the 100-400L.

Do you face problems with vignetting using both the 10 stop and the CPL at wide apertures? I tried doing this with the Hoya screw-in filters (NDX8 and a CPL) on the 24-105 @ 24mm and the vignetting was terrible.

I usually only stack them on my TS-E 24L II, no issues with vignetting there.

Lenses / Re: Aperture and Light
« on: April 25, 2013, 07:55:45 AM »
I just got the new 24-70 to replace my Mark I version of the lens.  Here is my question, given that the new lens has a diameter of 5mm more, does that mean that more light enters the lens?  I presume yes.  So, following that presumption, shooting the same subject in the same lighting at the same aperture and ISO speed, does the 82mm lens need less time to properly expose the subject?  If it does, it follows that the new lens is better in low light, correct?

Unfortunately, I sold the Mark I lens the day before the Mark II arrived in the mail so I was unable to test the theory.

More light might enter the front of the lens, but since the aperture controls the amount of light reaching the center, the 'extra' light won't change the exposure.

The bigger front element means less vignetting (and can help with other aberrations).

+1 on the tripod.

Big Stopper for the Lee holder - I have screw-in 10-stop NDs (B+W/Schneider), they're good but you can sometimes alter zoom on an extending lens as you screw it on. The Lee makes it easy to compose, meter and focus, then change exposure and slide the filter into place. 

I sometimes use both the 10-stop and a CPL.

Yeah, I'm getting posts blocked too.

I do recall the waist strap now, sorry!  Definitely not intended to be a weight bearing strap.

Turn off the backscreen, problem solved and u will focus more on actually taking photos

Now that's helpful.  I recommend you switch to a film SLR, having to pay per frame and wait a couple of days to see if a shot worked will teach you to be a better photographer. Maybe a psychiatrist can help you be a nicer person.

@ OP, use Custom Controls to assign Magnify to the Set button, and in one of the Playback menus there's a magnification setting, set that to Actual Size. Pressing Set during image review or playback will take you to a 100% view at your selected AF Point.

The Toploader Pro ships with only a shoulder strap.  If you're trying to use the shoulder strap as a waist belt, I can imagine you'd find it not substantial enough...

Canon General / Re: That's my money you are profiting from Canon!!!

Naw... not offended by you... just tired of hearing all the whining and complaining on CR over the last 12 months... Used to check out CR often but not any more... too many downers here.

Yes, this is off topic, but I agree with you.  It's been debated before, but I still see a strong correlation between the increasingly hostile and combative environment and the loss of the karma system.  It wasn't a perfect system, but I think it did manage to keep it more civilized around here.

Smite.   :P

Lighting / Re: 600ex-rt vs PocketWizard Flex TT5 Setup
« on: April 24, 2013, 07:06:50 PM »
I have both the PW system and an ST-E3-RT with three 600EX-RT flashes. I use the PW setup with a PowerMC2 for an Einstein monolight. If I'm not using the monolight, the PWs stay in the case and I use the ST-E3-RT.

Since you don't list a monolight among your assets, I'd go Canon RT.

For shooting sports anywhere but a pro venue (where the lights are bright for network TV), f/2.8 is the narrowest aperture you'll want.  IS is nice, if you can afford it...  Generally, an f/4 tele lens won't cut it (maybe on a 1D X).

I didn't consider the Jobu foot, but it looks like it would work fine.  For my 600, I was ordering other stuff from RRS anyway, adding the foot made sense.
