If you manually clean the sensor for at least 30 seconds (just enable manual cleaning dont actually have to touch the sensor) it will detect and map out dead pixels. At least it does on my 60d. Im pretty sure this is done prior to getting a new camera, dead pixels are like dust- you will eventually have some no matter what

I've never heard of this but it seemed to work with a 5DM3 that I have.  It had what appeard to be a stuck red pixel that showed up from ISO 100-3200 (didn't try 50).  It seemed to disappeared at 6400 but I have the high ISO noise reduction set to auto and I think that removed it.  Anyway, I tried an Auto Cleaning cycle from the menu and then a manual cleaning cycle for 30 seconds.  After turning the camera off and back on, no more hot pixel.  I even looked at a RAW file in PS with all noise reduction turned off and it was gone.  It may not work in all cases, but I'm glad I tried it because I'd been thinking about sending it in to Canon.  All they would have done was map it out so I saved myself from being without the camera for a few days.  Thanks Ryan708...

Lenses / Re: 24-70 F/4L IS - Why I will Buy/Not Buy this lens.
« on: November 06, 2012, 06:52:40 PM »
I was interested in this lens until I took a close look at the MTF charts of it versus the 24-70/2.8L II.  Canon made it a more dificult comparison because the vertical scales are a little different between the 4 graphs.  At $1500USD, I'd expect the f4 version to be closer to the f2.8 in image quality and that doesn't appear to be the case.  Compared to the f2.8L II, image quality falls of near the corners for a full frame sensor.  It would probably be a great crop sensor lens though...

Lenses / Re: Sharpest Ultra-wide Lens for Full Frame
« on: September 30, 2012, 04:29:04 PM »
The term "ultra-wide" usually means around 20mm and wider.  The 17mm TSE L is about as sharp as you'll get in that range and of course B&H has it but it's not cheap:

A 500/4L IS II and two that Canon doesn't make; 100-300/4L IS and a 20/2.8 TSE.  I'd take a redesign of the 20/2.8 if Canon would upgrade it to an L but the TSE would be nice to have...

5D MK III Sample Images / Re: Lanscape: 5D mkIII 24-70mmL
« on: September 26, 2012, 07:57:37 PM »
I enjoy threads where people discuss the need for an ultra-wide angle lens.  It is almost always when landscape photography is the subject.  Attached are three images taken last year at a lake near where I live to illustrate the difference of the three focal lengths that are most commonly discussed; 24, 17, and 14mm.  No they're not masterpieces but they do show how the perspective shifts between focal lengths change the importance of the various elements in the image.  At 24mm everything already appears twice as far away as it would with a 50mm normal lens.  As you step out to 17mm and then 14mm from the same camera position, the foreground becomes more and more dominate in the image while the background becomes less and less distinct.  That foreground domination is the reason to use an ultra-wide for some landscape shots; not to attempt to "get it all in" as many people do.  If the perspective looks right to you and you need a little more in the image, you need to step back a little, not switch to a wider lens.  If you do switch to a wider angle lens, you need to reassess the shot completely to make sure it is still a strong composition.

Software & Accessories / Re: GPS, does anyone really use this???
« on: September 18, 2012, 11:07:45 AM »
For travel writers/photographers, GPS is indispensable. No matter how good your memory, after tens of thousands of photos shot all over the world you cannot possibly recall where all of them were taken. Add-on devices, like the Canon GP-E1 for the D1X, 5D3 and 7D are expensive, bulky, add complexity, and serve a single purpose. Internal GPS, like in the 6D and Powershot S100, S110 have two downsides: they take too long to acquire satellites when you're frequently turning the camera on and off to conserve juice, and they consume more of your battery's power than the same camera body would without it. Far afield, when battery power is not easily replaced, this is a real concern.

I prefer to use a real GPS while shooting, like a Garmin CSx60, since it provides so much additional utility for navigating, setting waypoints, routing, tracking, etc, and is a far more sensitive and reliable receiver. I then use Early Innovations Photolinker software to match my daily GPS track to the day's photos. This tags each image with the appropriate coordinates in the EXIF data, shows you each image on a map, and allows for manual override when necessary (like when you're in a cave or slot canyon and loose the satellite signal). Lightroom 4 then displays each image's location on a world map once the image comes off of your memory card and into your computer.

I don't work for, am not sponsored by, or otherwise shill for any of these companies. This is just the best way that I've found to get my work done. There are a number of alternative geotagging software applications out there, but I haven't found any of them to come close to Jeff Early's Photolinker. It's fast, intuitive, comprehensive, and he regularly updates it. I hope this information proves useful.

The new GP-E2 replaces the need for a standard GPS unit for the 5DM3 unless you need it to navigate.  It acquires signal lock in less than 30 seconds most of the time.  I do a travel photography trip (usually to a country I'm not that familiar with) once or twice a year.  I was in Scotland last June for 2 weeks.  My memory is pretty good to but, 14 consecutive days of travel hitting multiple locations each day, the geo-tagging was a big help when I got home.  Plus if I ever want to return to the exact location I'll have the GPS coordinates to do it...

My only complaint about the GP-E2 is that it isn't powered by the camera and needs AA batteries.  I took lithium batteries with me and didn't need more than a 4-pack for the entire trip so it's not that big of a deal but it could have been made smaller if it didn't need the internal battery.

It is just another manufacturer's entry that makes the EOS M look stupid.  It has an EVF and built-in popup flash.  At least in other parts of the world, Canon is including the external flash with the camera (not here in the US).  The Fuji X-E1 kit also includes a 28-80 equivalent f2.8-4 zoom instead of the usual f3.5-5.6 uber slow zooms that most include...

Software & Accessories / Re: DPP for MAC too slow?
« on: September 06, 2012, 11:16:07 AM »
I use the Lion versions of Canon's software on Mountain Lion.  DPP runs fine.  I too shoot RAW.  DPP is not my tool of choice but it doesn't exhibit the symptoms you describe.  The edit window goes away immediately when dismissed.  The only other thing I can think of would be if you were accessing the same image files from another application at the same time and getting into some sort of file locking situation...

EOS Bodies - For Stills / Re: Canon EOS M System Announced
« on: September 06, 2012, 08:56:35 AM »
Looks like Fujifilm has announced the mirrorless camera with the features that I'd have liked Canon to include (mainly an EVF, built-in flash plus hotshoe...).  Check out the E-X1 instead of the X1 Pro.  If Canon had produced that camera with the option of using my EOS lenses through an adapter, I'd have pre-ordered one.  The EOS-M is nothing I'd consider...

Interesting.  I have it on the latest generation of MacBook AIR running Mountain Lion and am not experiencing any problems.  I use it when traveling and take a small WD 1TB Passport USB3 drive for extra storage.  I typically do not edit a lot of images at one time keeping the image count low per folder.  Being and AIR, it only has a 1.8GHz Intel processor.  The one big difference I can think of is that it's local drive is a pretty fast SSD instead of a traditional hard drive.

Anybody else notice the complete lack of EXIF data on the images?  Are they really from a 1D X.  I haven't seen anything come out of my 1D X looking like that and I too own a 50/1.2L...

EOS Bodies / Re: Canon 1DX VS 5D MKIII Cameras
« on: August 30, 2012, 07:28:37 AM »
To me, if you have to ask, you've never shot with a 1 series Canon camera.  I have both and both fill a need.  The 5DM3's silent continuous shooting mode alone makes it a more appropriate camera for some subjects and events while the 1D X is a vastly superior camera in just about every other way.  One thing that people overlook about the 1D X is the accessory difference.  Both the WIFI and GPS accessories take power from the camera so no bag full of AA batteries.  I have a GP-E2 GPS for the 5DM3 and it works great for GPS coordinates (not so great for direction...) but it requires AA batteries and it sits in the hotshoe.  Yes you can use it with a USB connection but it's in the way.  The 1D X accessories are smaller and attach to the left side of the camera.  A plus for me besides the obvious camera build quality, built in vertical grip, weather sealing, better AF, higher frame rates, etc... of the 1D X.  It was tough to make the decision to sell the 1DM4 to partially finance the 1D X but, in the end, I'm glad I did.

EOS Bodies / Re: Anyone else preorder the EOS M yet?
« on: August 23, 2012, 09:28:51 PM »
I don't plan on buying this version.  It doesn't make any sense to me other than as yet another P&S and, in that light, I'd probably buy one before a G1 X.

The EF adapter is really odd for a camera with no viewfinder or even an option of an add-on viewfinder.  By the time you add the adapter plus an EF lens, it would be very unbalanced with most of the lenses and certainly awkward to hold out in front of you to shoot with.  If you're wagging a tripod with you, you might as well have a normal DSLR.  A T4i makes more sense to me if lightweight is you goal.

The first EOS M is more of a step up for people that have progressed to the point of wanting better image quality than their cell phone can deliver...  ;D
