EOS M X

EOS M Y (as in, Y did we make this camera?, or, Y isn't this camera selling well?)  ;)

I'd get the Pro version.  You're 5DIII is likely under warranty, you're buying a 1D X.  The multipoint test can reveal issues with the camera's AF system.  Even if your lenses are fine, different lenses have peak sharpness at different apertures - that info may (or may not) help.  I figure if you're spending thousands on gear, a few bucks on software to get the most from that gear is money well spent.

I need a DSLR - my other requirement is filming

I have to say, if you think it's a challenge to take stills of jewelry, shooting good quality video with a dSLR is orders of magnitude more challenging (and most likely requires lots more accessories, most of them costly).  Just sayin'.

Buy. Or wait...the update to the 1D X should be along in 2-3 years.

Insurance is great - when you done with the shoot, returning home and will have time to replace the equipment.  However I always get nervous at the start of the trip - if I loose my equipment, insurance will not buy me a new trip

True. But as I said, I have confidence in the setup. To be honest, I do usually hold the 600 II by the tripod foot when it's on the strap. But I let the strap take the weight.

As far as BR strap, I trust an anchor point I screw into the plate or body.  I am not comfortable with a small clamp (e.g., the Kirk system) which could get loose and have camera crash to the floor.

You might think so - my experience has been the opposite.  With the BR FastenR lug connected to a tripod socket, and the strap connected to the lug, the rig is swinging from that lug. That puts torsional stress on the screw.  I used to use that setup - even with a tight connection and moistening the rubber compression washer prior to tightening (as BR recommends), it would come unscrewed on a walk/hike. That happened more than once (didn't fall off, but would have had I not noticed). I got in the habit of checking tightness a couple of times an hour, and at least once every couple weeks I needed to re-tighten the lug. The same thing would happen with the FastenR-T1 that I used with the Manfrotto RC2 plates.

Since switching to the AS system and the Kirk clamp connection, it's not come even slightly loose once. I've given up checking the connection at all. The lug is attached to the clamp with Loctite - that's where the torsional stress is, and with Loctite it won't come loose.  The clamp has a good intrinsic resistance - brushing the knob won't loosen it. Plus, the clamp is placed so the knob is under the lens when attached to the body, and away from the body when attached to the lens - there's minimal chance of even brushing it.

Bottom line, after two years of using the directly connected lug, I learned that it needed to be checked often because of a tendency to come loose, and after a year of using the Kirk clamp, I have complete trust that it won't come loose unless I intentionally take it off.

An alternative is to ditch the sling bag and go with a Think Tank technical belt and pouches for individual lenses.  I like this arrangement for ease of changing lenses.

I do something similar on occasion. I have a Spider Holster, another great carry option. I avoided them until they came out with an Arca Swiss clamp option.  I don't use their belt, I attached the holster to a Lowepro Deluxe Technical Belt, and I can attach lens cases, a monopod holster, water bottle/phone case, etc., to the belt as well.

EOS Bodies - For Stills / Re: 5D MK III Focusing Question

With the 60D's 9 AF points, auto selection wasn't terrible - if it picked the wrong subject, you knew.  But with the high density 61-pt array, you can get a lot of shots that are just a little off, it'll grab the shirt instead of the eyes, leading to OOF shots.  Combine that with the thinner DoF you get with the same aperture on FF vs. APS-C, and you've got even more slight misses. 

Spend time with the AF system.  In Custom Controls you can set the multicontroller so it directly selects AF points.  You can specify a default point, even a different default point depending on camera orientation.  Pressing in on the multicontroller takes you to the center.

Have fun!

If I understand your problem - using a strap and attaching to tripod without hassle - the Kirk security strap is the best solution IMO

I think the OP wants to hang two cameras.  Have you tried a pair of Kirk straps, over each shoulder?

Sounds like you're used to automatic AF point selection, aka letting the camera pick your subject.  You are the photographer, and you're smarter than your camera. I suggest you tell your camera what to focus on, rather than the other way around.  Use single point selection mode, moving the active point around with the multicontroller and putting it over your chosen subject.

Lenses / Re: Tripod collar on the 300, 400 & 500 f2.8's
« on: May 03, 2013, 03:04:10 PM »
Neuro, have you used the 400 f2.8 and the 500 f4 and if so, why is the 400 roughly 4 pounds heavier? Is that 2.8 glass that much of a difference? The 500's are BIG and heavy, we'd like to get 400's but the weight....phew! Not to mention, the price...

400/2.8 = 143mm diameter front element, vs. 500/4 = 125mm.  A 14.4% larger diameter means a 31% larger area, and since elements aren't flat, larger elements are relatively thicker, too.  So yes, it's the glass. 

OTOH, the new 600/4 II and 400/2.8 II had some dramatic weight reductions, they're basically the same weight as the 500/4 MkI (the 400 II is 20 g lighter, the 600 II is 50 g heavier).  That's thanks to fewer elements (including elimination of the protective meniscus lens in front of the front optical element) and more titanium in the construction. The 500/4 II shaved 1.5 lbs off the MkI (decent, but much less dramatic than the others - the 500 lost 8% weight, the 600 lost 28%).  Of course, the cost went up. A lot. Bottom line, if you can handhold a 500/4 MkI, you can handhold the 400/2.8 II and 600/4 II.

I hang 12 lbs of gear costing upwards of $20K from the BR strap w/ Kirk 1" clamp.  But then, my gear is all insured, just in case...  ;)

6296
Blackrapid double strap, Kirk 1" clamps on the ends of the straps, Arca-Swiss type plates on bodies/lenses and an AS-type ballhead clamp.

... if they were removeable to lug around hand-held.

You'd not want to 'lug it around handheld' without the tripod collar, IMO. The tripod foot makes a great handle.

Visit your local hardware store for the painter's pole of your choice (various lengths, telescoping, etc., all inexpensive), then put a Kacey Pole Adapter on the end for the standard 5/8" stud.

The blue means you need to set your white balance properly (assuming the background is white).

You may not be able to get enough DoF with a close-up subject, even if you stop way down (and lose sharpness to diffraction at those narrow apertures).

Many people assume a macro lens is best for products, not necessarily. The TS-E 90mm f/2.8 is arguably the best product lens - tilt allows you to adjust the focal plane to give an apparent deep DoF at more moderate apertures.

To get the whole ring in focus with a macro lens, you need to look into focus stacking (software like Helicon Focus or Zerene Stacker).

The strong, directional light that PBD mentions would help the shot a lot - diamonds should sparkle!

"Grace L Ferguson Storm door and Camera Repair Service"
what's that?

It's like Joe's Bait, Tackle, and Camera Repair Shop, only a little better because your camera doesn't smell like fish when you get it back.  ;)
