Lenses / Re: A few Sigma 150-600mm f/5-6.3 Sport sample images

I found it difficult to magnify them much, they seemed to me to lack quality compared to my 100-400L.
Since they are advertising photos, probably taken with great care at f/8  and likely hundreds of images were taken to get the three, I'd expect to see every hair in sharp focus.  They should easily beat my photo from my 100-400 at 400mm and cropped at  f/8

They're full size images; go to Download -> View All Sizes and you can see the full size originals. It looks brutally sharp to me at 600 f7.1 in that hippo shot.

I tried that on the deer, the highlights had a lot of halos, and the hair looked over sharpened.  Still, it did look good for the price.  Its more what I had expected.

I just know that people who throw themselves into the middle of any and every technology discussion, with a no-need-to-change position, using you-are-mislead-to-believe-you-need-anything-else arguments and those-who-say-differently-are-ignorant-illogical-and-non-factual judgements, they look a bit funny ...

And, people who repeat themselves over and over, trying to show that taking a photo with a 5 stop underexposure makes them a expert.  That's whats sad.  They should show their properly exposed photos.  I happen to believe that any of the major camera models are capable of taking supurb photos, as are the successful photographers.  The composition, lighting, and subject matter is where the money is, not a ability to take a poorly exposed photo and improve it to a less poor but still unacceptable photo.

The poll options are limited.  99.99% of my images are not limited by my hardware, but by me.  I doubt if many images would have been improved by new gear, since composition and subject matter are what makes a great image.  I've used cameras since the 1950's, it was manual focus and rule of 8, or a light meter then, and that did not cause issues.  I like AF and auto exposure, but they cause more spoiled shots than doing it manually.

Lighting / Re: First Flash
« on: September 30, 2014, 12:45:43 PM »
I'd read up on lighting before buying just a single flash to use for portraits. 
A Canon 90EX can be had for $50 from Amazon, and it will act as a master to control a off camera flash like the 430 EX, which works well with it as a slave.  I'd recommend two flashes at a minimum.  I have the 90EX and use it with my G1X MK II, 5D, and 5D MK III to control my 580 EX II.

Software & Accessories / Re: How to use a non-collar lens on a gimbal
« on: September 29, 2014, 09:54:07 PM »
My first thought was why use a Gimbal for a small lens?  A monopod would likely be fine.  I guess there are cases where you might save on packing multiple items into the field.

Pricewatch Deals / Re: Deal: Canon EOS-1D X Body $4799

The gray market cameras are purchased from overseas dealers, usually Hong Kong or Singapore.  They get incentives for meeting sales goals, so they are happy to sell a few hundred for a small or no profit.  As for used, that has happened too.
Always use a credit card, and be prepared to do a chargeback if the seller does not settle any issues, and ebay can't get you a refund. That's generally not a issue, but it has happened.
Canon has been tightening up on warranty service for gray market.  If you have a sales receipt from a authorized dealer, there is no problem.  You can purchase third party insurance, but then there is little or no savings.

Does this mean that the 7DII wont be supported by DPP 4?

DPP4 initially supports full frame, but Canon has said it will eventually support all of their cameras.  DPP4 is like IOS 8, pretty buggy, you don't want to use it.

Beware that Canon Europe may refuse any repairs to your equipment.  I'd contact them to find out what they will do.  Its expensive to have to send equipment back to the USA for repair.  You also need to keep purchase receipts to avoid hassles with Customs coming and going.
My experiences with moving companies has been poor.  Get private insurance and document everything.  The moving companies want to sell overpriced insurance.  If your company handles the moving, then they will likely insure it.  I had thousands of $$ damage on a international move.  My company had insurance which covered it.  The moving company lost future business due to the high number of expensive claims.  They lost a lot of business from a company that did hundreds of international moves a year, and many thousands of US moves.

Third Party Manufacturers / Re: iPhone 6 gets an Exmor
« on: September 29, 2014, 08:03:40 PM »
Looks like even iPhone has moved to Exmor.
Actually, Sony’s Exmor-R back-illuminated sensor was first introduced in the rear-facing camera of the iPhone 4s. The iPhone 5 had the same sensor as the 4s. Then Apple moved to the Exmor-RS (stacked) with the iPhone 5s, the 6 and 6 plus having the same sensor as the 5s.

What's new in the 6 and 6 Plus is only the front facing camera, previously a 1.2 MP BSI OmniVision in both the 5 and 5s, now Sony Exmor-RS.

Yup, Sony is a big supplier of sensors to all phone makers, whoever wants can buy them.  Sony's problem is that they keep trying to build phones, but its a cut throat business and they keep flopping.
Well, the rear-facing camera of the 6 Plus has also optical image stabilization as a new feature, but the sensor is the same as the 5s and 6.

The up load to CR seems to be killing the contrast. I think this is what has happened to Tex pictures. I've modified mine accordingly.

The Forum converts the images to PNG, but they suffer.  I try to link mine directly from SmugMug so no uploading happens.
I took some shots of our local Inland Grange trail riders again last Saturday.  I've done it every Fall since 2010.  I shoot the images when the riders are heading out at 10 AM, take them home and do a little cropping and adjustment of lighting, then print them on 4 X 6 photo paper, and have them back for the Grange when the riders return at about 12:30.  The grange sells them for $5 each which goes into their operations.  We live out in the country where the grange system is still going strong, community members all pull together to support each other.  Rather than bog the thread down with a lot of images, you can see them here:

10mm would fill the frame on a crop or it would be close to circular on a full frame. 

I am wondering if it will really be a fisheye. 

You can read the patent, it says Fisheye.  This is not a rumor, just reporting on a patent.  There is a diagram straight out of the patent in the article, it also says Fisheye.
I've never seen the 14mm Samyang sold as a fisheye.  It merely distorts the image horribly.
Tokina has a history of decent wide angle lenses sold for a low price.  I have a old 17mm f.3,5 and its very good.

To be clear, the G7X does not have a 24-100 mm lens. It has an 8.8-36.8 mm lens which, when crop factor is applied, renders an equivalent field-of-view to a 24-100 mm lens on a 35mm sensor.

...and an equivalent DoF to an f/4.9 - f/7.6 lens on FF, for equivalent framing.

For those who use P&S cameras and are used to a huge DOF, this should be popular.  I've seen many who were disappointed with the shallow depth of field from large sensors.
The shallow depth of field is useful to creative people who understand what is happening and want to control what is in/out of focus.  Some, maybe even the majority of P&S users just want everything in focus.  There is certainly nothing wrong with that.

The 7D MK II is about one stop worse than the 1D MK IV in this comparison.  I used mine at ISO 12800.  Use Raw, not jpeg.  The older jpeg engine in the 1D MK IV probably does not reduce noise as much as the 7D MK II, the noise is there, the 7DII just has more NR.
Compare them yourself, the 7D MK II at ISO 6400 is very similar to the 1D MK IV at 12800.
I compare the yarn for detail, saturation, and contrast.

Is it a Canon grip or third party?  Are you using Genuine Canon batteries?
If you have narrowed it down to the grip being installed, and its a genuine Canon grip, then contact Canon.  Batteries can also be counterfeit and cause weird things to happen.
If its a third party grip, Canon won't help you.
