Canon General / Re: DxO Mark explained
« on: December 15, 2012, 12:59:27 PM »
Excellent write up, and it matches my experience with my D800 and 5D MK III sensors.  The D800 sensor is supurb at low ISO settinngs below 400, while my 5D MK III pulls away at high ISO settings.
Since I do mostly extreme low light photography, I was disappointed with the D800 performance in low light, but amazed when I used ISO 100.
The thing that is not touched on, are the aspects of a camera system.
Reliability
Service (time and quality for repairs)
Lens quality and available focal lengths that match sensor resolution.
There are other personal preference things like ergonomics, ease of use which tend to vary with user background.
He did touch on the issues with editing of large raw files, but a lot of people do not know exactly how to quantify this.  I found it taking multiple times to render a low light D800 image compared to a 5D MK II image, and running NR or other computation intensive processes was very slow when you were trying to process 500 or more images.

Canon General / Re: Canon's FF DSLR sensor under the microscope
« on: December 15, 2012, 12:21:42 PM »
I have yet to see a good explanation of what advantages a .18 micron process gives.  Canon has the capability, so apparently they have not been seeing a compelling reason either. 
My first thought was that wiring traces that must run between pixels could be made smaller, and on chip transistors could be made smaller, but I have read that it is not possible to make the ground and power traces  smaller due to crosstalk and voltage issues unless you adapt Canons new patent for a rear illuminated sensor.  The transistors could likely be smaller, so thats a incremental improvement.  Using more of the available surface area for photocells is obviously a good thing. 
I'm certainly all for new technology if it improves the sensors, but not for new technology just for its own sake.

EOS Bodies - For Stills / Re: Canon 7D: 'I need a Must Have's List'
« on: December 14, 2012, 12:10:16 PM »
You should consider getting a 17-55mm lens, it will really make a difference over the Kit lens.  You did not mention which kit lens you bought, so its a bit hard to make specific recommendations, but the 10-22mm ef-s, 17-55mm ef-s and a 70-300mmL shouuld be at the top of your list.

Pricewatch Deals / Re: Massive Nikon D600+24-85VR Deal - $1996
« on: December 14, 2012, 01:07:05 AM »
Nikon is having a big rebate sale that started today.  Times are tough, and sales are slow. Virtually everyone has the deal, since its Nikon sponsored.
Expect a lot of big deals over the next week or three.

Lenses / Re: problems with canon 50 f1.8
« on: December 14, 2012, 01:02:58 AM »
It could be a lens issue.  Another common issue is not using enough light, FoCal wants very bright light.

Sounds like Amazon.  The lens is $150 everywhere due to the Canon Rebates, it is a good price.

Technical Support / Re: How to AFMA precisely without Lenscal?
« on: December 13, 2012, 08:08:49 PM »
+1 on FoCal.

There's a DIY solution here: http://www.the-digital-picture.com/Photography-Tips/AF-Microadjustment-Tips.aspx

+1 with Neuro on FoCal.  It will be a great tool if you plan to add more lenses. DIY kit takes WAY too much times.

Call Canon and tell them you want to make sure both camera and lens are perform at best level. I  doubt they will charge money for this task, since you spent over $5k on their product and both items are still under warranty.
Canon will adjust your lens to match a reference body, and will adjust your body as well.  If you have other lenses, or get them in the future, you will be asking the same question again.
FIRST, check to see if you need a adjustment.  Put the camera on a tripod, focus on a flat wall with Detail and snap 10 images at the widest aperture resetting the focus to infinity between shots.
Now, do the same using live autofocus while in liveview.  Unless the liveview focus is noticibly better, you do not need to do anything.  You should try at varying distances and zoom settings. 
 
You can put two different AFMA values into the camera for zooms, one for minimum zoom, and one for max zoom.

Lenses / Re: Ditch 100L for 70-200 L II ?
« on: December 13, 2012, 07:57:36 PM »
get a sigma 70-200 os for portrait and you will get a greato portrait lens and you will retain the macro one
I would not call a maximum magnification of 0.13 Macro, the old non OS version had a .29 magnification.  Still not macro, but better.

http://www.dpreview.com/lensreviews/sigma_70-200_2p8_os_c16/
The Canon 70-200mm MK II has a .21 magnification which is not Macro either, but better than the Sigma OS..

Lenses / Re: Performance of Carl Zeiss 25 f2.8 ZF on 5d2
« on: December 13, 2012, 07:35:02 PM »
I'd check out the 25mm f/2, I've heard it's amazing.  From what I understand the 25mm f/2.8 is one of the least impressive in the ZE/ZF line.
WHY?  He got the lens free from a cousin, he is only shopping for a adapter.

EOS Bodies / Re: Moving to 6D from 5DII
« on: December 13, 2012, 07:32:33 PM »
It is a upgrade, but slight at best.  No reason to sell a 5D MK II to get one.

Software & Accessories / Re: Lost image files from Canon DPP software
« on: December 13, 2012, 12:47:37 PM »
You can recover them from the formatted card.
DON'T USE IT UNTIL YOU DO!! If you use it, you might overwrite some of the deleted files.  Formatting the card in camera merely tells the card that its ok to overwrite the deleted files, but they are not actually erased.
 
There are many recovery programs that work well.  I use Image Rescue 4, which I bought after trying the freeware ones and finding issues with all of them when trying to recover RAW files.
You will likely have to rename the files, since the original name will be lost, so make sure you do not duplicate names and overwrite another file.

Adapters for Nikon to Canon are very simple machined rings with a release mechanism, and are low cost.  The lens will work fine. 
 
Its not a particularly wonderful Zeiss, but good for the price you paid.
 
Here is a review.  Note that they used a Nikon version with adapter for the test.

Technical Support / Re: Canon CPS International Repairs
« on: December 13, 2012, 12:34:26 PM »
Have you contacted the Canon repair center in Japan?  They would likely help you if there were a real issue.  However, it sounds like you have a cosmetic issue, which, to me, does not fall under helping photographers keep their equipment running.

EOS Bodies / Re: 6D vs 5Dii - The End of an Era?
« on: December 13, 2012, 12:30:24 PM »
The 5D MK II is indeed going away.  Canon is not going to keep making them at the price they are selling for, and is likely just selling down slow moving inventory.
I expect the price to rise after most are gone, just as it did with the 5D Classis.  There will always be some who want another new 5D MK II and will be willing to pay top dollar for it.

Lenses / Re: 100mm macro L on a 7d
« on: December 13, 2012, 12:24:05 PM »

Though I have nothing my 7d has mounted several fantastic lenses including the 200 f2,of all lenses I liked the 100mm the mistake have constantly been using my friend's 100 L(i can probably compose with my eyes closed)

Since you have used and like the 100L, trust your own judgement, its what counts.  Each person views things according to his method of photography, but its what you like that should determine what you buy.
