Nikon has taken Sigma seriously and sued them for US$ 116 million and the Tokyo district court ordered Sigma to US$ 14.5 million, for patent infringement case for lenses with VR technology. Here is teh summary of judgement as posted by Nikonrumors site:
Here is the summary of the judgment:

"Nikon obtained the patent related to VR technology in 2002. The content of the patented invention relates to technology wherein a vibration detection device, which detects the amount of camera vibration at angles around photographic objects, prevents the influence of vibration of a motor for lens and thereby allows more accurate photo shots. Sigma affirms that the scope of the patented invention does not include any functions which reduce the influence of camera shake. However, Mr. Osuga, the Judge in Chief, states that the effects of the invention in Nikon’s specification is described as “it allows image blur to be reduced” and that the specification clears that it includes camera shake. Thus, Mr. Osuga stands for Nikon’s assertion. In addition, Mr. Osuga points out that image blur prevention system requires various control functions, and he states that this patented invention of Nikon’s should be rewarded based on the contribution of the patent to the defendant’s products, that is 15%. Therefore, the Tokyo District Court calculated profits earned by Sigma to be a maximum of 10.1 billion JPY, and found compensation of damages to be 15% of the profits of the accused products earned by Sigma."

Any suggestions to remove them? I did order clips but they have not come.
Pulling the background tight is option #1

Just before you hang the backdrop, wet a hand towel and wring out most of the water, then throw that in the dryer with the backdrop for ~15 minutes, which will steam out most of the wrinkles.
Interesting tip ... will have to try it out sometime ... thanks for sharing.

EOS-M / Re: Is the canon eos-m a dead end system?
« on: March 10, 2014, 01:06:50 PM »
;D ;D ;D ... believe it or not, using the focus peaking feature, the a7R with a cheap adapter is actually much faster then the autofocus on EOS-M with its native lenses. I've had the EOS-M for almost a year and made over 30000 images with it, and I was very satisfied with it's image quality ... but after having tried some of the competing mirrorless cameras, I sold the EOS-M last week ... now I plan on getting a Panasonic GX7 and a Sony a6000 ... pretty sure of getting the a6000 (when it is released), but I'm still undecided about the GX7  :-\

Did you update the firmware on your M?  I thought that made a significant improvement, and certainly faster than what I can achieve (at least with wide apertures) manually on my A7r (not that speed is usually an issue for me); though of course you may be much more adept at mf than I am....

As for the GX7, it certainly has its admirers, but its IBIS isn't nearly as good as that in Olympus bodies (esp. the OM-Ds), and the one I briefly owned never made images that looked as sharp as those I get from my Olympus - but maybe I had a bad copy.

Meanwhile, I suspect this post is closer to the truth than many around here would like:

Yes, I did update the firmware for the EOS-M and yes is it was much better, but still not up to competing mirrorless cameras ... that being said, I never had any problems with not being able to capture good images due to AF.
By the way the url you posted is returning an error ... could you check/re-post

Thanks

EDIT: Never mind, it is working now (might have been a temporary issue).
Very funny, enjoyed reading it ... to me, it sounded like a story more about a dumb salesman who does not know how to sell cameras and a customer who has no clue about what he wants.

And now Dylan a tough question. Actually a very tough one: Does your wife know? Does she even  know about this poll?  ;D ;D ;D

If the size and color is same as my 400mm f2.8 IS II, she couldn't tell the diff. That why I ruled out Tamron ;D

That is truly very Funny, deceitfully crafty, and smart.
Nice opportunity to blackmail him for a 10% commission or we rat on him to his wife. ;D

Rienz, I just removed you from my "buddy list" >:(.........Just kidding ;D
By the way, I was seriously considering blackmail for 10% commission, but since you have not removed me from your buddy list, I think I should also be nice and reduce my commission to only 7% of the lens price  ;D

This thread seems like a good place to ask this.

I've always been an admirer of Irving Penn's portraits (Worlds in a Small Room, Small Trades, etc.). I've never figured out how to recreate the look of his backgrounds. I've only seen seamless paper in solid colors and while the muslin backgrounds come close, they just aren't quite the same. As others have said, unless you have some means of permanently leaving them hanging they are prone to wrinkles, which one would think wouldn't be a huge problem if you can blur the background, but unfortunately, even with full frame, it seems like there is never enough background blur to hide the wrinkles.

From pictures I've seen, it looks like Penn used Canvas.

Anyone here have any sources or ideas.
I have no experience with these kind of backdrops, but I just ordered a "Wrinkle Free" backdrop from Amazon.
I can tell you if it is really "wrinkle free" after it gets delivered to me in about couple of weeks. Meanwhile, here is the link for what I ordered

Sigma has a USB dock already. Has anyone used it? Any opinions on that ?
One of my colleagues bought the Sigma USB dock (along with the Sigma 35 f/1.4 lens), so I got a chance to hold it, but from what he tells me, he never updated anything with it yet (this was about 45 days ago) ... as pointed out by Kai (the crazy Digitalrev guy), the light to indicate, that it is working, is bloody under the USB dock, i.e. in a place where you cannot see while using it .. kind of a strange place to keep it ... and that's about what I know of the USB dock. If you haven't already seen it, here is the youtube video Kai had posted last October

+1 Having flash memory (if they indeed have flash memory) is NOT ENOUGH. It's their willingness to backup their lenses with GOOD SUPPORT. So, they have to MAKE the firmware to upgrade the one residing in ... flash memory... So, as I said feel free to spend your money and test good support later. And by later I mean many years actually as many as with Canon lenses.  Because if someone gets an expensive lens with very good IQ they want to keep using it or ... sell it. Certainly not ditch it...

You just brought up a great new idea: third party makers could add a USB connector to their flash devices or make a special USB dock for their lenses. This would make firmware upgrades really easy ....
For several years now, Metz, (a German consumer electronic company) has been routinely providing firmware updates on their flashes (for customers to update on their own), to address compatibility issues with newer cameras. I still have the Metz 58 AF 1 flash (which I bought in 2008) and have updated the firmware at least twice, until the plastic hot shoe broke ... now it just sits in my cupboard to be used as a wireless flash once in a while. Also, Sigma has the USB dock for their newer lenses. I think in future we will see more and more manufacturers coming up with USB firmware updates for their lenses and flashes etc.

WTF. Did anybody bother looking at the links I provided in my posting ?????
Relax, we are not stealing your thunder, I did read and understand that you were already aware of their existence, I was merely stating my experience of having used Metaz flash and also having tried the Sigma USB dock ... so the credit for mentioning them first goes only to you  ;) :) :)
Peace

Third Party Manufacturers / Re: Panasonic Lumix GH4 ...
« on: March 10, 2014, 11:58:26 AM »
Just got an email from B&H with the price for Panasonic GH4 - US$ 1699 - that's US$ 1869 with shipping and customs (for me) for body only ... and if you also want the interface unit with 2-Channel XLR Inputs, than the price is US$3299 (i.e. US$ 3603 with shipping & customs)  :o :o :o
Last week when I had severe GAS (before I knew about its price tag), I was thinking about pre-ordering the GH4 ... but now, no way ... freaking quarter size sensor (of my Sony a7 or the 6D), costs the same as a full frame camera :o :o :o ... the Sony a6000 which will be released around the same time (with some awesome features and a much bigger sensor), is costing only US$648.
But this is a worrying sign, coz if a micro four thirds camera like the GH4 is going to cost this much, what will Canon/Nikon charge for 7D MK II/D400 :-\

Had the same feeling when I opened up that email this morning. I would've actually considered it just out of value and curiosity had it been lower.
+1 ... if it was about or under $1000, I would have bought it, coz I recently came across a small camera store in our local mall, there are lots of used lenses for the micro four thirds cameras, for really cheap prices ... so I was thinking about messing around with a few of those lenses, especially since the GH4 has inbuilt image stabilization and some very good features ... but despite its very good features, I don't think it is worth $1869.

'Tie-dye' muslin backdrops in blue, gray, gold are common and versatile backdrop colors.
Neuro, you are bad news for people (like me) who suffer from GAS  ;D ... I never heard of Tie-dye and didn't even know what the hell it was, until I read your post ... and just ordered a Tie-dye  Blue Muslin Photo Backdrop from Amazon.

My vote goes to EF 200-400 f/4 L IS w/1.4x TC .... as I prefer zooms to primes, coz I just don't have the patience to change lenses.

i've been using the sony a7r since it came out. prob shot 1000 images.. havent had any problems at all.
Absolutely! ... I've made over 15000 images with so far and haven't noticed any light leak issues ... of course screen blackout between shots and slow start-up times are a bit annoying but nothing that hinders my photos.

« on: March 10, 2014, 12:07:37 AM »
Heck man, this illustrates that every shoot presents untold amounts of unexpected problems and you just gotta be ready to work with/around those problems.  Loved it!  The photographer has a good and cheerful attitude and that helps everyone else keep going.  Better equipment does produce better quality but more than anything it merely makes getting the shot EASIER.  Better equipment doesn't replace the photographer or their vision.
True the photographer was very cheerful with great attitude.
