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...

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.

Sad, indeed... I feel your pain. Here's my solution. Awkward, but it works. Like me.

I think the insight, expertise, and thoughtfulness of the summed above posts on what should be a fairly simple engineering issue, is remarkable. I am very concerned about BR's cheesy metal for its carabiner. I am also, though, disappointed with Canon's own design of the lens-release button: I can;t imagine it would be too difficult or expensive to make that a bit harder to release so that a 'lifeline' would become unnecessary. I have tried to attach 2 photos to this post--I hope they come through. The first shows cheesy BR construction; the second shows my Rube Goldberg but effective remedy for the release on the lens...

The questions in this post are unfortunately near and dear to my heart. (I dearly love my BR straps and I have 3.) The OP and several respondents raise excellent issues. First, my gut instinct tells me that the camera came off because the little tubular thingy that in theory locks the carabiner came unscrewed, and the coat compressed the spring on the carabiner. (I see no other way, if the attachment-point was still on the camera when it was recovered.) Second, I am alas dismayed by the cheesy construction of the carabiner itself-- a) it is easily worn down, because it is a cheap casting, by constant rubbing against the nice stainless attachment; and b) the pin/swivel at the top that goes into the square buckle that slides up and down the webbing is the weak point in the whole link--if is breaks, there goes your gear.  I have repeatedly talked with BR about this, to no avail.
The other issue is: what happens if the strap is mounted to the tripod-collar, and the camera separates from the lens? (This happened to me, and to others on this board.) I have made a small length of 2 mm climbing shock cord, about 4" in length, with a bowline in each end. One end is permanently through a spare BR attachment point. This goes into the BODY of the camera. The free end of the cord (with its bowline) goes into the carabiner. So if the camera comes off the lens, it doesn't hit the ground or bottom of the Zodiac or whatever, it just dangles for a moment. It ain't pretty, but it works. (Like me.) I shall try to post a pic of this. (The carabiner, not me.)

Terrific.. I didn't know that anyone else's wife referred to their gear as 'the other girlfriend.' My wife won't even walk the dog with me if I have any gear with me.
And since this came up in this thread ... I cannot speak highly enough of cpsusa. They are my safety-net... get it if you can, it's worth it.

EOS Bodies / 5D Mark III USA/Canon-recognized warranties?
« on: December 15, 2013, 05:13:19 PM »
Colleagues: I see the 5DIII intermittently sold by B&H, Adorama, or BuyDig for about $2900. Does anyone know whether a) these have fully-kosher Canon warranties that are recognized by CPSUSA; or b) whether these occasional sales may be available after the xmas buying season? Your thoughts gratefully appreciated.
