Extremely interesting, valuable, and informed discussion. Thanks to all. I also plan several extended trips, though not in such harsh environments. I'd think about carrying a smaller daypack of any sort, inside your large backpack. Two points, though: a) have you considered wheeled luggage of any sort? (I have the largest Eagle Creek backpack with a detachable daypack, neither ideal for photo gear, but doable in mild environments.) But b) whatever else you jettison, DON'T omit 2-3 backup hard drives. If you don't have multiple rugged HD's, you will regret it. Even if only an array of large USB thumb drives... for God's sake don't minimize backup!

A mentor. Sometimes called an 'editor.' Or a guru. What a NYC cop calls a "rabbi." Someone with much more experience than you have, an eye and a production record similar to what you want to achieve, and the willingness to help you murder your own children. If you find such a person, treasure them. Remember, they are not your friend. If you want a friend, buy a dog. Your dog will not help your photography. A guru will.

Believe me, I sympathize... My own approach is to try, try, try to describe the problem as accurately and exactly as possible, and then let them fix it... My mother always told me, "Johnny, don't tell a surgeon how to operate."
And I also learned that it really IS possible to take out one's own appendix; but it is less painful and messy to hire a surgeon to do it for you.
I myself have had very good luck with California's CPS, though in truth I have never sent them complex problems. ...
Again, I sympathize...

Lenses / Re: Danny Green Talks the Canon EF 100-400 f/4.5-5.6L IS II

One hopes that the 100-400 will come with the same black-box warning that the 70-200 comes with: "Do not photograph women older than 21 with this lens. The extreme sharpness of the lens may cause damage to the health of the photographer."

Colleagues: I have been a loud partisan of BR straps for a long time. I have though had two scary separations of lens from body (one caused damage; one was a near-miss), neither of which was due to BR strap problems. I am convinced the separations are due to unintended release of the lens lock from the camera; and I would urge Canon to make a secondary lock that prevents such unintended releases. However, I have rigged a bit of shock cord while carrying my 70-200 attached either to the 5D3 or 1Dx. It takes a bit of time to make such a cord (2 bowlines on a short cord); and it impedes rapid lens changes; but gravity is an implacable and unforgiving enemy of photo gear.

Third Party Manufacturers / Re: Woe and Pathos in the Sigma 50 Art?

I am very grateful for your input. PLEASE keep it coming. I have the USB dock and will get to work on it; will also try lensAlign. I admit to a high degree of extreme paranoia about sharpness. This is my problem, not Sigma's. But I just finished a 2-hour theater shoot with the 70-200 and 24-70 and I saw lots of liquid and fine red capillaries on eyeballs, handheld, wide-open (the aperture, not the eyeball); and so my paranoia is bone deep. I'll give it a try though. Thanks again, keep it coming.

Third Party Manufacturers / Woe and Pathos in the Sigma 50 Art?
« on: October 06, 2014, 11:41:30 AM »
(Please excuse any unintentional etiquette errors: I posted this in another topic link and I shall remove that one.)

I bought a Sigma 50 Art. I am not at all happy with the focus: it is gorgeously, excruciatingly sharp ... about 1/3 of the time. My standards for "sharp" are pretty high, and my reference lenses are the new 70-200 and 24-70. I am a thoroughly experienced photographer with decades of work behind me.
I am utterly baffled; I never, ever have this problem with other lenses; I have never, for instance, used microfocus adjustment on my 5D3 or 1Dx for my reference lenses. Here are a couple of photos from the other day, and I was focusing on the inner corner of the left eye (the 'medial canthus.') By the way, re. the girl with horns, do not adjust your set, you are not hallucinating: the dots on the cornea are contact lenses ... I will leave these up for a few days. Your thoughts deeply appreciated.

Triggermike --- Time well-spent. Good for you. Lovely shot.

Lenses / Re: Rubber covering loose on zoom of 24-70 II - advice?
« on: August 25, 2014, 12:58:21 PM »
Thank you each and all. I called the NJ CPSUSA (couldn't, inexplicably, get through to Irvine) and was very very well-treated by John DiMauro, one of their contacts. I ordered the ring, part # YB2-3754-020, confirmed that this was for Model 2 ZOOM ring, and paid all of $6.15. The real test will be whether my klutzy fingers can get this puppy on. Given my (remote past) extreme difficulty correctly applying condoms, I am worried about this; but the consequences of failure with the lens-collar are less severe, and less expensive.

Lenses / Rubber covering loose on zoom of 24-70 II - advice?
« on: August 22, 2014, 04:38:23 PM »
The rubber grip or cover that fits on the zoom ring on my 24-70 II has come loose and become very slightly stretched out. At this point it is a minor annoyance, not a disaster, though I am going overseas next week and don't like surprises. Any suggestions for managing this problem? Or should I send it back to CPS (after I return) and get it replaced? Thank you for your time.

I use BR very happily but may take a swing at the Peak Design alternative for my occasional shoulder carry. But in that vein, two questions:
First, I was always raised that I should not carry a camera on a strap if there is a heavy lens on front (e.g., the 70-200, or 300) because it may deform the front of the camera body and make focusing inaccurate, because it may distort the relationship of the lens mount to the sensor (or film...) -- is there still truth to that, or no?
Second, the Peak Design loops--the ones that fit on the camera's strap points-- what has people's experience been with whether they show wear before breaking? Wear on a part exposed to friction doesn't bother me; the replacements are cheap; but sudden failure of a weight-bearing element does ...  I appreciate y'all's hive expertise...

Software & Accessories / Re: Insurance is an accessory right? :P
« on: August 10, 2014, 06:07:45 PM »
Excellent question. First, USAA has great service; we've had it for 30 years. Second, I itemize my gear by S/N and send them lists periodically. Third, there is some question how much pro use vs. hobby use excludes coverage. [Be very careful there, because insurance companies are NOT your friend (just like health insurance); if there is a big claim they may try to exclude you for pro usage.] But if you have any pro usage, then insurance clearly is a business expense. How much your deductible should be depends on your personal financial circumstances. You may want to look at NPPA's member options for all-risk insurance with Hayes.

The autofocus issues with the new 50 mm Sigma ART are very dismaying, in light of its great build quality and image quality.
Has anyone had autofocus issues (or any other such issues) with the 35 mm Sigma ART?
I use the 5D3 and 1Dx.
Thoughts and advice deeply appreciated.

Please pardon my erroneous posting location--I put this post originally in the Canon section -- my error, sorry.

Lighting / Need advice re. video tutorials on 600 Speedlight usage
« on: April 30, 2014, 09:29:29 AM »
Comrades - I always refer to the sun as my light source. But now I am looking for a source of video tutorials on use of speedlights, from soup to nuts -- starting with the absolute basics of 'how to turn this on', through correct flash exposing in various venues and fill situations, up to use of multiple flashes with the radio triggers (either canon or aftermarket.) Strobist seems too complex, and I want something geared specifically to thorough use of canons. Either free or for-pay. All suggestions gratefully appreciated. Thanks for your time.

Remember that you have every right to shoot whatever is publicly available

And they have the right to insult and berate you for it; neither is civil.  If you wish to claim every millimeter of the law, you must concede to others the same.

Orangutang, I must respectfully disagree with you. It is correct that I have the right to shoot whatever is publicly available. And onlookers (including police or security guards) do have the right civilly and politely to ask me about my activities. But they do not have the right to threaten, harass, detain, intimidate, or in general cause fear or disruption to me. If I as a reasonable person (and I do NOT mean those professionally-offended professional victims) am intimidated or made fearful by an insulting or berating onlooker, I have the right to be free of that intimidation. (The handout on the adkins website is quite clear on this point.)
