To me, $12,000 dollars for a "18 MP still camera" seems a bit on the steep side. 
Especially so when I can accomplish the same thing in Servo Mode and Photoshop Stacking.

Watch the video, it's not about an "18 MP still camera".  It's about pulling images from 4k video - not something you can do in Servo Mode and Photoshop.  I agree with you on the price being steep.

Yup. I think I commented on this ability elsewhere: the 1D-C is a 24fps 8MP camera. If you double the price of the 1DX (which does 12fps), then voila, you're in 1D-C price territory.

Get a low cost FFbody  and invest in a good lens.  A 24-105mmL is a excellent start, so a 6D Kit might be the way to go.

I disagree. Now that there are some very excellent 24-70's, forget the 24-105 because at the wide end it is useless due to distortion.

The lens to get would be the Tamron 24-70/2.8 VC.

And add to it the Canon 17-40/4. Why this lens? Because the 16-35 isn't really that much better. It is faster, but still just as weak in the corners, etc, so you may as well save your pennies and buy the cheaper of the two.

There's every change that the camera is rubbing against a metal stud on your jeans or belt or jacket or ... and that would account for the scratches.

The 5D Mark III is a magnesium-alloy body.

That means to make it look black it needs to be painted.

If you rub any metal that has been painted for long enough against clothing, the paint will eventually wear away and show metal underneath.

I would expect them to have a black anodised finish which is what all my Canons have had. Certainly a simple painted finish will never last long.

I was going to mention that it wasn't spray painted on but regardless, that doesn't stop it from wearing away.

The places that have not been photographed like crazy are definitely the places you have to hike miles to get to. I did not see a single photographer when I hiked up to Nevada Falls or going to the top of upper Yosemite falls, but saw hundreds around the valley floor. After hiking 15 miles one day with all my camera equipment, snow gear, and water & food on my back, I dont blame most photographers for sticking on the valley floor.

That's only because it is winter and for the most part, those trails are usually considered "closed" at that time of year.

That was the day you hiked to the top of Yosemite Falls? Consider that you did this in cold weather and that people do the same amount of walking, carrying the same amount of gear, in summer.

At least for me, 15 miles would only be 5 hours of hiking during good weather in Yosemite.

I did notice that about 80% of photographers were walking around with a 70-200 F2.8 (canon/nikon/tamron/etc.). For the life of me, I could not figure this out! For my entire trip, I was constantly reaching for my 14mm uwa lens. If that was not on the camera, the 50mm was. I only put my 70-200mm on my camera 3 times over the course of the trip.

And when I look at your photos, what do I see? Uncorrected lens distortion.

Where does lens distortion come from?

UWA lenses that people don't know how to use.

Your photos are a great example of why lots of people don't use wide angle lenses in Yosemite Valley.

Best lens for the Yosemite Valley is arguably 24-70. It would be 24-105 except that the 24-105 is rubbish wider than 28mm.

I would happily argue that the best lens for Yosemite is a 24 or 17mm tilt shift lens, but everyone has their preference. The distortion is corrected for as best I could (using a lens profile), but that is definitely the downfall of the Samyang 14mm. I am sure I could have done a better job correcting the distortion, but I have not figured out how. If you have any advice feel free to share!

Buy yourself a copy of "DxO Optics 8".

And what ISO were you shooting with f/16 at 1/100? Somehow I doubt it was ISO 100, with a polariser and ETR.

To give an example, a photo I've taken from an almost cloud free day at Yosemite overlooking the Nevada Falls is 1/25 at f/8.0 for ISO 100 (zoom of 25mm). In the interest of seeking to maximise my chances of the photo being sharp I use a tripod even if it is borderline ok for handheld with IS.

No, I was a bit above ISO 100.  I wasn't using a polarizer.  If I had used one, then yes, I can see why you would want a tripod.  However, on a clear sunny day in fall, unless you are shooting extremely bright clouds, or again...water falls...I don't see a reason to use a polarizer or ND filter.  Some of those people I saw, were indeed shooting water...but I was referring to the ones that were just shooting landscape with a lot of bright sky, mountains, etc.

...
Many of the landscape shots didn't turn out all that well, compositionally (I've not spent much time going through them yet).

... and you wonder why everyone isn't using a UWA lens on their camera.

EOS Bodies / Re: 7DII and D400 Specs
« on: February 26, 2013, 06:54:27 AM »
There is an interesting letter over on DPReview http://forums.dpreview.com/forums/thread/3387936#forum-post-50901841 that purports to be from Nikon Europe that unequivocally states that the D7100 will not be Nikon's flagship APS-C format camera.

On paper, the D7100 is impressive. If Canon responds with something close in the 70D, it makes me wonder what they'll put in the 7DII.  I'm not sure the current rumored spec list for the 7DII would be sufficient to justify an $800 difference in cost.

On the other hand, I keep wondering if the 70D and 7DII will share the same sensors (Or for that matter, if the D7100 and D400 will as well). There is a part of me that thinks Canon may differentiate the two by offering slightly fewer megapixels but better low-light performance in the 7D, as they have done with the ID-X.

Hard to say. I just thought the letter was interesting and worth starting a thread for people to consider what it might mean for the 70D and 7DII.

I think it is very obvious from the specs of the D7000 and D7100 that neither are contenders for the D300/D300s line of cameras. Saying that they are makes about as much sense as calling the 70D the successor to the 7DII if the 70D comes out before the 7DII.

What did surprise me was the multitude of people shooting standard wide angle landscape shots in the daytime, on tripods.  I fail to see the logic of this.  If they're shooting macro, or wanting to participate in the "stream water as smoke" fad, with long exposures and ND filters, that's one thing.  Or if it is late afternoon light, then yes I can see needing a tripod.  But if they are not doing long exposure, there's no reason for a tripod in mid afternoon light, in my opinion.  It certainly limits the total number of shots you can take, to constantly move around a tripod and set it up, and aim the camera, etc.  I had rented a 1D4 with 24-105 IS.  I shot about 1400 pictures over a day and a half.  With the IS, I was able to close the lens down to f/16 or 18 at times, to try to minimize CA at the wide end, and still got sharp shots handheld even if the speed was less than 1/100.

And what ISO were you shooting with f/16 at 1/100? Somehow I doubt it was ISO 100, with a polariser and ETR.

To give an example, a photo I've taken from an almost cloud free day at Yosemite overlooking the Nevada Falls is 1/25 at f/8.0 for ISO 100 (zoom of 25mm). In the interest of seeking to maximise my chances of the photo being sharp I use a tripod even if it is borderline ok for handheld with IS.

This is the 2nd time that a f/2.8-4.0 wide angle zoom has been mentioned.

The black gaffer tape is definitely something to consider for the future. I'll be interested over time whether this grows as a problem or whether its just bad luck. I don't know how the camera is made but it looks like metal covered by clear plastic , coated then in black plastic. The black plastic layer seems very thin.

The 5D Mark III is a magnesium-alloy body.

That means to make it look black it needs to be painted.

If you rub any metal that has been painted for long enough against clothing, the paint will eventually wear away and show metal underneath.

Oh, if you want to stop this type of wear, buy some black gaffer tape and tape the bottom edge of the camera.

Hello There,

The finnish on my 5D Mark 3 is wearing away around the bottom left edge of the camera.

It looks like it's 5 years old..not 5 months old.

I have no idea what wore the finnish away.

Anyone else have this issue?

I've had this issue with every DSLR that I've owned.

On the plus side, at least we know you're not a "trophy" photography that just collects expensive cameras and pretends to take lots of photos.

It can be fixed by having Canon replace the back plate but that's not free.

EOS Bodies - For Stills / Re: How Do You Clean your sensor? And how often?
« on: February 24, 2013, 06:15:59 PM »
Either before or after every major expedition I use a rocket blower on my sensor, the back element of all my lenses and the lens caps that cover the back of the lens. Sometimes I also clean the sensor/lens rear element whilst on a shoot.

Once a year or so I send my camera in for a proper clean.
