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.)

Note to original poster: alas, your experience is ubiquitous. Morons think they know either photography or the law (and know neither), and feel as though they have the right to brace you about shooting. They don't. Period. My response is to start off easy: 'I am a local photographer, here's my card, I do a lot of street shooting, which is what I am doing. Wanna see a few of my pictures?' (A few bucks for a business card is money well-spent.) If they persist, I tell them they are interfering with me, and please leave.' If they persist, I put on my 'I'm planning a left thoracotomy for you' look and say 'If you have a problem, call the police. If you don't, I'll call the police, and then you will really have a problem.' I rarely get to step 3, but I have.
Remember that you have every right to shoot whatever is publicly available, not because you are a respected surgeon (as am I), but because you are an American citizen exercising your rights in public. (This varies overseas.) The literature on the rights of street photographers (professional and otherwise) is extensive; you may want to look at NPPA's website, and there is a host of others.

Lenses / Re: New 50mm Sigma - question re weatherproofing?
« on: April 18, 2014, 02:14:20 PM »
Please forgive me if I am treading on already-discussed ground; but what has experience been so far with regard to the new Sigma 50 1.4 in either dusty environments or damp (like humid or rainy) environments? Reviews  say 'not weatherproofed'-- does this entail some clear-cut difference between their lens and, say, the Canon's 1.2 or 1.8 lenses? The difference in weight is of no consequence to me. Thank you for your advice.

The real questions are: a) how strong is your wife? and b) how tolerant is she? I suspect from your kit that the answer to both is "very." Yer a lucky guy.
But seriously ... it depends on what you usually shoot. I'm a street/people guy, not architecture etc.,  and would take at least the 70-200, the 35 1.4, and a 24-70. I like the 135 f2 very much for street work, and it's less obvious. I'd check my homeowner's policy and make sure you have a scheduled, all-risks, replacement-value overseas coverage.

Lenses / Re: Affected with GAS, Gear Acquisition Syndrome
« on: February 22, 2014, 04:46:52 PM »
Certain aspects of this thread (re. smuggling) remind me of a) first sneaking better and better bottles of wine into the cellar; then b) what is euphemistically called 'off-site storage'; then c) a separate charge card... I wonder whether the difference between a 5D3 and a 1Dx is visible to the untutored eye. Not the photos. The body.
If all else fails, eschew GAS for a month, take the money you 'save', and spend a month on the road in, say, Mongolia or Argentina. Take lots of CF cards.

is this available in usa and if so from whom?

Technical Support / Re: Help! My Camera Won't Focus After Cleaning It.
« on: January 12, 2014, 09:35:21 AM »
Ah, the old diopter-wheel agony ... I feel your pain. I had the same confusion, and the same embarrassment when I learned about it. On my 5D3 I use a small piece of shiny black electrician's tape over the wheel. It works. I also heroically came to the rescue of a pretty young damsel in distress who was shooting an important event and was bewildered by why nothing was in focus ... my wife (!) steered her to me and I heroically reset the diopter-lever (I think she was using a Pentax) .... I mean, it doesn't get me a Navy Cross or anything, but she was grateful.
And the old "I'll sell X after I get Y" routine ... yes, we all feel your pain. Anyone here buy Canon stock?

Lenses / Re: Get a 300mm or 600mm? Oh the agony...
« on: January 05, 2014, 01:55:13 PM »
Oh, the agony, indeed... this discussion is a bit rich for my blood ... but arbitrage, those 2 bird shots you put up, HANDHELD, are astounding. I don;t know what your denominator is; but those two are just gorgeous. Mazel tov.
I myself use the 300 2.8 II and absolutely love it--IQ is unparalleled and it is easy for me to manage (I'm pretty strong); I seem to seem some IQ falloff with TC's though. It is about the only lens I use routinely that is sharper than my 70-200 II. Makes me wonder whether that falloff is a function of barely-noticeable camera motion vs the extra 2 air-glass interfaces ... my distance stuff is mostly sports and mostly handheld or monopod.

Good point, I considered that; but my concern honestly is about disconnection of the lens from the Canon, rather than failure of the carabiner or the post at the top of the carabiner. ... good point though.

With a rig like that, Mr. Neuroanatomist, I would suspect that there is probably an identical notch in your left clavicle ...

Yes, this is original BR OEM. They switched to the smoother lock nuts later on, and that is what they currently supply. I was (and am) very supportive of the basic BR concept/design, and was an 'early adopter'; but their quality of material is IMHO suboptimal.
