Having had both, I pretty much agree with the video, it seems pretty fair and I see the same things.
 
What he doesn't mention is that Nikon does not have a 135mm f/2, or a 100-400mm lens that are in the same ballpark as the Canon lenses.  For landscape with the D800 and the 14-24mmG, a landscape shooter will be very happy.  However, my D800 was very noisy as ISO got up to 1600, but it took NR very well.  However, a low light shooter might not be very happy with it.
 
The DR at lower iso's in the D800 is simply amazing.  Difficult bright sun and shadows just are no problem, while my 5D MK III struggled just as my other Canon bodies struggle.  I've learned to live with it, but it was really nice to not have to worry about high contrast scenes.

Why not post a link to your flickr page, or limit your post to 4 images?  It is really annoying to have my computer hang while it is downloaing dozens of images.  Not everyone has gigabit internet.
 
By the time my computer came back to life, I was too disgusted to enjoy the ton of images.

Be nicer! I'm sure it took a long time for the poster to post all those images, and it's not your computer that's hanging, just the time it takes for the photos to download. The CPU load is almost nothing for viewing images on a website, at least with any computer more recent than 1995 or so. (I remember a 1980s computer that was still being used, and it took about two seconds of processing time just for the cursor to hover over a "rollover" image and show the "highlighted" version.)

Believe me, your computer has no ill effects as a result. I know you know this, but I just wanted to remark that our inconvenience (I have slow internet at the moment as well) is more than made up for by the huge amount of time that the poster had to invest in producing such a huge post.

The point is that 4 images are enough in a post.  Thats why CR limits attachments to 4 images.
 
By posting a link to a website where many images can be viewed, its just plain easier on viewers with slow internet, and the poster does have something to share, so we'd all like to see at least a few of the images. 
 
A alternative would be to post small images that can be clicked to download a larger version.

The issue with low cost tripod heads is jerky pans.  Unfortunately, the good ones are very! expensive, so get the Manfroto, its low cost and will not win any awards, but its at least competent.
 
Then, someday, you can get a Oconnor.  http://www.bhphotovideo.com/c/search?atclk=Brand_OConnor&Ntt=video+head&N=4291309161
 
And the legs  are cheap by comparison  http://www.bhphotovideo.com/c/search?Ntt=oconnor+tripod+legs&srtclk=sort&Ns=p_PRICE_2%7c1&N=0

You forgot to mention the non-replaceable battery.    ;)

great catch! that one is [CR5]

I think the battery is a CR2

Lenses / Re: Canon EF 180mm f/3.5 L USM Macro lens discontinued ???
« on: June 05, 2012, 11:10:44 PM »
Its due for a update, maybe they will announce it soon, and deliver in a few years?  I'm getting pretty cynical about Canon lens announcements.  I am equally cynical about Sigma vaporware lenses.

Third Party Manufacturers / Re: My D800 Review
« on: June 05, 2012, 10:48:11 PM »
consider renting some top end Nikkor glass for a weekend/week?

Like what?  Isn't the 24-70mm f/2.8G glass I own top end?  Its certainly priced like it.  I'm not going to try a 200mm f/2, because I couldn't afford it, and the focal lenght is not one I use. 
 
Nikon's top lenses are very sharp, but no different from Canon when it comes to AF variabiliity.  And, many of the top ones, like the 24-70 f/2.8G  have excessive CA's. 
 
Then, they have nothing comparable to my Canon 100-400mm L, or my 135mm L.!

Lenses / Re: Can a UV filter affect IQ (sharpness) on a lens?
« on: June 05, 2012, 07:02:03 PM »
Filters always affect IQ, even air affects IQ, its just a matter of how much.  Although I have plenty of B&W and Heliopan filters, I avoid using them unless its dusty, or likely to get damage, water, salt spray, etc on the lens.
 
I always kept a filter on my 17-55 and after 3 years had no internal dust.  That was the one exception to my occasional use of filters.
 
I have very few cases where the difference in sharpness would be noticible except by obsessing ofer a 100% view of the image.  For a wide angle lendscape where I need all the detail I can get, I'd remove any UV filter.

So as everyone knows Apple has a lot of followers and their products are indeed quite 'cool'!
If Apple entered in the photography/camera business it would steal a lot of costumers from another big photography brands like canon and etc. and that's why I'm posting this. do you think that would happen?

have a look here: http://www.macrumors.com/2012/05/31/apple-working-on-standalone-point-and-shoot-digital-camera/

they are not entering the DSLR market though.

 
Some of the very first point and shoot digital cameras were sold by Apple, but were made by Kodak and Fujifilm.  I used to own one.
 
Apple's idea of a digital camera that needed a Mac to operate flopped, and they got out of the business in about three years.  They were dropped by the Visionary Steve Jobs when he came back to apple along with the laserwriter.  None of those things had a future :D

EOS Bodies - For Stills / Re: 5d mark III srceen protector????
« on: June 05, 2012, 06:36:32 PM »
Go to www.acmaxx.net. They have 5dmkiii lcd screen protector made of hard poly-carbonate with UV low reflection coating. It's better than glass or plastic ones.
They dont sell direcly, but tell you where to buy depending on where you are living (including Ebay).
I have them on my T1i, 50D and 5D MKiii; all were bought from Ebay.
They are good ones to protect your investment.

 
Hard polycarbonate scratches easily.  Canon uses a hardened glass similar to Gorilla Glass that is much harder to scratch.  If it does, you can get a new cover from Canon and install it yourself.
 
Remember, you are not toughing the LCD screen itself, just the LCD protector built in to the camera and secured with doubleback tape.

I think its smart to be paranoid about losing images, but I haven't heard of a camera zapping both cards.  How many images have you lost in the past?
 
The technology is here NOW to quickly backup your images to a remote device, Canon has a wifi transmitter that is high speed, or you can get a slower EYEFI card to backup up your jpegs.  It can back them up as you go, and why worry if it is not instant, if it gets behind, it will catchup when you take a break.
 
For really important big money projects, multiple backups are made ASAP and kept in different pllaces so a single event like a fire, plane crash, etc will not get them all.  Even then, money is not unlimited.

There's an interesting article in the May issue of the British Journal of Photography that compares the low-light capabilities of the 5D mk3 and Nikon D4. Both cameras use their own 24mm f1.4 lenses in the article. As I've just bought a mk3 and Sigma 85mm f1.4 I thought the article would be pretty informative but was quite surprised to read:-

"Fast lenses are only part of the solution, as the microlens structure of sensors has the effect of limiting the maximum effective f stop - you get the reduced depth of field, but not the true lens speed. To compensate for this, camera firmware detects apertures faster than f2.8 and applies additional  gain. You must add the gain mapping applied at all apertures to compensate for vignetting."

It goes on to say that shooting at f1.4 and ISO 6400 will probably give you ISO 25600 in the corners. Yikes!

Well, you learn something new every day.

I guess those shooting Leica with a Noctilux f0.95 must feel robbed!

 
 
Here is another article on the effect.

In the FoCal manual, it says Canon recommends 50x focal length for testing distance. I did a DoF calculation. For 200mm, you would place the camera 10m away from the target if following Canon's recommendation. At this distance and f2.8, the DoF is 0.26m with 0.13m for both front and back. So the tolerance of in-focus is pretty loose. If you place the camera 25x focal length, the DoF is only 0.06m which is much shallower. I don't know how sensitive FoCal is in detecting the sharpness difference, but I would definitely place the camera closer in hope to improve the testing accuracy. Plus 50x focal length is too far a shooting distance in practice for non- super tele-lens. 25xfocal length appears to be a good distance to use. Any thoughts? Thank you!

 
AFMA settings will vary with distance.  The 50X distance is not going to be optimal for those who like to get close.
Here is a screen shot of one of the tests I ran.  Its pretty obvious as to where the best AFMA lies, so the main thing is to adjust it at the distance you use. 
 
If you shoot your 200mm lens at 2 meters, then adjust it there. All lenses tend to front focus at close distances.  The 50X distance applies where your typical image is not a close focus image.
 
I hope that explains it a bit.
 
 
With focal, you are going to get a curve like this, with the peak being obvious.  Being off by a couple of AFMA units usually makes very little distance.
 
HOWEVER, the curve may shift left or right depending on the distance, and near mfd, it can be a big difference.

Thanks for the suggestions Mt Spokane Photography. Would I not make more profit though if I sold in the UK where cameras seem to be more expensive?

Also how important is the box to most buyers? I mean, I could hand carry two brand new 1D Mark IVs into the UK but if I have the box then it could complicate duty issues.

Thanks.

I'm not sure about UK Sales, being from the USA.  Certainly, they have stiff import and GST taxes, you might be better off getting the seller to provide a receipt showing a quantity discount, and just paying the taxes.  Then you do not put a buyer at risk.  That original box is going to be worth $$$ as far as sales price goes.
 
I've found that a person does need to understand all the ways you can get burned with imports.  I import products from China for resale in the USA.  They really pile on the fees.  Shipping and fees are sometimes more that the cost of the product.
 
Shipments to me usually have a few packages opened at random by customs, and are sometimes x-rayed as well.  They charge to truck them to a warehouse for inspection, charge for inspection, charge to truck them back to the holding warehouse.  Loading and unloading fees everywhere.
