Technical Support / Re: Are you on drugs?

Why would you disassemble a camera to replace the clock battery on a camera that has a user replaceable clock battery?

On page 41 of the 5D user manual there are instructions how to remove one screw to remove the clock battery holder.

The battery drops in to the holder.  Then you slide it back into the camera then replace the one screw that holds the tray in.

The user manual is a free download from all canon sites.


This is like buying a new lamp to replace a burnt out bulb.

RTFM!

You are clueless.  I know what I'm doing.  There is a internal issue with the connection of the clock battery to the motherboard.  Replacing the clock battery does not fix that issue.

EOS Bodies / Re: Is Canon now two generations behind Nikon?
« on: Today at 04:07:11 AM »
I bought a D800 after reading the hype.  It was a waste of money, I sold it and bought a 5D MK III.  The D800 appeals to armchair spec readers, but few that actually use one are happy. It is very good for landscape at ISO 100, but as a all-around camera, the 5D MK III is better.

Hopefully, the D810 is going to work out, but I'm not about to get one after my experience with the D800 and the high CA's in Nikon lenses.  Nikon has improved some of their lenses since the D800, but their 24-70 f/2.8 is way behind the Canon version.  Since you have to put a lens on a camera, a poor lens wipes out any advantage the body might have.

There have been rumors off and on every since the 100L came out.  Canon is able to keep new lens plans from leaking even better than the plans for new bodies.  Canon seems to be still concentrating primarily on video, so I expect to see new lenses that are dual purpose still / video.

EOS Bodies / Re: Grey Market 5DIII vs. USA Model
« on: August 28, 2014, 05:18:26 PM »
The retailer that you do not mention leaves us guessing.  Some are reliable and deliver what you order, some are scammers.  Yes, even those selling gray market cameras fall into reliable and switch and bait.

Go to Canon price watch.  They list the best of the gray market sellers.  There are some like Abes of Main that they refuse to list.

http://www.canonpricewatch.com/product/03868/Canon-EOS-5D-Mark-III-price.html

Personally, I'd go for the CPW street price deal and get a authorized seller of US models for $200 more.  Canon has been reported to be tightening up on servicing gray market cameras under warranty recently.

I have a Kirk Ball Head, I think its a BH1.  They are a fine head.  RRS might be better, but also expensive.  Don't overlook Markins, they are in the top performer group as well.

For sports, it really depends on the situation.  You would use a entirely different lens for indoor sports in as dimly lit gym than for a outdoor playing field in daylight.  Your location also plays a huge part.

I'd suggest that for outdoor use, a 300mm f/4L would be marginal, a 400mm lens better.  For indoors, the 200mm f/2.8 or even 135mmL might work, depending on how close you can get.

There is a 120-300mm f/2.8 zoom from Sigma that is reasonably priced and might be a option if you want a zoom.  I'm admittedly not a Sigma fan, but the lens definitely fills a need.

EOS Bodies / Re: Pricing for the 7D Replacement
« on: August 28, 2014, 12:26:41 PM »
At 3,000.00, a used 1D MK IV will be a far better camera than a $1800 7D MK II.

As I said, my MkIII's (though they are 1Ds's) slow down when I put SD cards in them, the fastest rates I get with the various cards I actually own are when I just have Sandisk CF cards in the CF slot and nothing in the SD slot, every SD card I own is slower than the various CF cards I own.

You are correct.  Even the fastest SD cards are blown away by a fast CF card.  In a mark III, the fastest write speed you will get with SD is 10mB/sec, most are 5.  The card specs are misleading to a extreme.

No, the specs of the flash card aren't misleading.  Fast speeds simply require you to have a device that supports that speed.  Unfortunately, the 5D Mark III doesn't support UHS-I, so the flash card falls back to pre-UHS-I speeds.

AFAIK, the only Canon DSLRs that support UHS-I speeds are the 6D, the 70D, the SL1, the T4i, and the T5i.  On the 6D, the difference between a 30 MBps Sandisk card and a 95 MBps Sandisk card is like night and day.

Yes, they are misleading.  They only apply to a new card.  As soon as you use the card, and do a normal in camera format, the speed drops to 10MB/sec.  To recover the speed, you need to do a low level format / erase of the SD card.  Do that with a 64GB card, and you will be waiting for it to finish for a long time, since it must write 0's to every memory sell on the card. 

People believe the hype without understanding the limitations.  You do not see the issue with CF cards.  My 1D MK III was far faster with a CF card.

Sometimes the specs are up front about this.  For example, they post a maximum and minimum speed here.  The Maximum speed is only for a blank card in a camera with UHS-1.  A Class 10 card has a 10MB/sec minimum write speed, and that is what users will see once the card has been written to.

Technical Support / Re: DPP "transfer to photoshop"
« on: August 28, 2014, 12:10:34 PM »
According to cpn.canon-Europe, DPP 4.0 is only compatible with 64-bit OS...so why would I have to have the 32bit version of photoshop installed??

I'm only pointing out what the user guide says, not explaining it.  Its likely that not all the components of the program are 64 bit.  I've copied the section and highlighted the pertinent info in Red.

From the Help Section:

Transferring a RAW Image to Photoshop
A RAW image can be converted to a TIFF image (16bit) and transferred to Photoshop.

Select the [Tools] menu → [Transfer to Photoshop].

Photoshop starts up and the transferred image is displayed.


A single image can be transferred at a time
Only one image can be transferred at a time. To send multiple images at a time, see "Batch Transfer Images to Image Editing Software".


Compatible versions of Photoshop are 7.0 or later.

Transferred images are automatically converted to TIFF images (16bit) to which an ICC profile is added. The ICC profile contains information about [Preferences] (Color Management) or work color space set for each image as described below and the appropriate color information is relayed to Photoshop.

When you exit Photoshop, only the original RAW image remains, and the transferred image will disappear. Saving the transferred image as a separate image in Photoshop is highly recommended.

For CS4 or later versions of Photoshop, this function is not available if a 32-bit version is not installed.

EOS Bodies / Re: EOS 7D Mark II & Photokina
« on: August 28, 2014, 12:04:00 PM »
But if Canon said: "Canon today announces DETAILS of it presence at Photokina 2014..." where are they ??????

Some people get confused by the hype easily.  Its best to never buy anything based on written information if you try to read your own wishes into it. The article was describing the layout and operation Canon booth at the show, nothing else. 

New product announcements will be announced the week prior to the opening of the show.  There may be prototypes at the show, or just large photo shopped images.

There will also be lots of brochures.  They are printed in advance, and its likely that CR guy has a photo of one.  He is not going to show it and risk outing the source.  Canon extracts revenge on leakers.  If a employee leaks something, the company he works for is punished.

Technical Support / Re: Anyone Repair your own DSLR Bodies?
« on: August 28, 2014, 11:51:03 AM »
At work, when I dis-assemble an unfamiliar piece of equipment, I shoot a video of me doing so....

It has helped several times on re-assembly......

That's a good idea.  I happened to have the Canon service manual which has step by step instructions, drawings and photographs, and even the type and length of the screws at each location, so taking my own photos wasn't needed.

I did the same calculations for the Nikon D800 and D7000. You would expect them to have virtually identical resolving powers since their pixel sizes are 4.88 and 4.78 µM, respectively. And that is what I calculated, giving some credence to the calculations I did for the Canons.

MTFcrop/MTFff with identical lenses is close to 0.63 for all lenses (on the dpr widget), compared with 0.66 expected from the relative pixel heights of both sensors. The relative resolving power of the crop, given the 1.5x less field of view is:

R = 0.945   (compared with R= 1.02, calculated from the ratio of pixel sizes).

The 36.6 mpx ff beats out the 16 mp crop since, when cropped it is at least as good as the crop sensor and has all the advantages of FF when not cropped.

The issue with the D800 was that even carefully done tests by experienced testers, DPR, for example, had to use extreme measures to get the resolution the sensor is capable of.  Ordinary users do not stand a chance, since even the tiniest vibration blurs some of the pixels.  You must use high shutter speeds, and for telephoto shots, where you want more reach, its even more difficult.  Turn up the ISO so you can use a faster shutter speed, stop down to increase lens resolution, and you loose resolution due to noise.

The gain is real, but almost unattainable, even by experts.

Candc & jprusa... I spoke with Canon, and they said the new DPP 4.0 was 64bit. Possibly I might have to change something in the windows registery.

Just read the help section on transfer to photoshop.  It says, in a backward way, that a 32 bit version of photoshop must be installed.

Adobe used to install both 32bit and 64 bit when you installed it from the program DVD.  With CC, only the 64 bit version is installed.  My last full version was PS5, and it installed 32 bit and 64 bit.

It sounds like Canon tech support is confused, their own help file points the limitation out.

Adobe CC only installs the 64 bit version, and DPP requires the 32 bit version.  Canon is still holding out 64 bit support for a number of items.

When a new camera came out, I was able to use that function to edit images in Lightroom or Photoshop before support was added by Adobe.  I'm adverse to converting them to DNG.

EOS Bodies / Re: F8 AUTOFOCUS
« on: August 27, 2014, 03:40:23 PM »
Yep, fully aware of that, but it's beside the point: I'm letting people know that despite suggestions to the contrary, both the 7D and the 70D will work in circumstances which some on here have stated they won't work in.

If you use a non reporting TC, even a old 10D will autofocus at f/8 with some lenses.  Others do not work.  I've tried in numerous bodies and lens combinations over the years.  The TC you use also makes a huge difference, some work better than others.

They do not track a subject fast enough for bif, but for a still object in bright light, they work fine.  My 5D MK III worked much the same way before the firmware update.  It is now more stable with F/8 AF then it was with taped contacts or non reporting TC. With some lenses, it just rapidly vibrated the focus at F/8.
