EOS Bodies - For Stills / 5D Mark III at F/8 and smaller Tests
« on: April 01, 2012, 12:14:03 PM »
I started testing my 5D MK III for autofocus beyond f/5.6 yesterday.  I decided to start by using my 1.4X and 2X Mark II TC's stacked together rather than taping pins.  The day was overcast, and dim, but not exceptionally dark either.
I had my 135mm f/2 L handy, so I put both TC's on it (F/8) and it had no problem autofocusing about 40 feet away, but it was quite slow.  Then when I tried it on some flowers 6 feet away, it chattered rapidly, focusing back and forth as though in a loop.  Back to a 20 ft distance it focused slowly again.  I tried it numerous times with the same results.
Then I tried my 70-200mm f/4 IS (F/11 equiv), it did not even try to focus (my 1D MK III would snap in with this combo when focus was close).
Next, my old non is 70-200mm f/2.8, (f/8 equivalent).  It autofocused reasonably fast and reliably every time with the 2 TC's stacked.
Finally, my 100-400mm L at 400mm (f/16 equiv).  No go not even a attempt to focus as expected.
Next, I'll tape the pins and try the 70-200mm f/4 + 2X TC (f/8) and the 100-400mm L + 1.4X (f/8).  I'm thinking it might work.
i'll post the results.

5D MK III Sample Images / 5D MK III Sharpness Test
« on: March 27, 2012, 04:16:53 PM »
My new 5D MK III came last night, I played with it a bit, but to get the best sharpness, I need to AFMA my lenses.
So, for a sharpness test, I tethered the camera to a pc, with my 100mm L macro and took two shots that were focused using live focus, which is usually about as good as you can get.  focus point was the AF / MA switch.
One image at f/2.8 and one at f/5.6.  Then, I cropped the focus point to 100%.
I converted the raw images to dng using Adobe DNG converter 6.7 Release Candidate 1
The results were sharp as expected.
100mm L at f/2.8 ISO 100 (1/80 sec for f/2.8 and 1/25 sec for f/5.6) Sharpening and NA set to zero, but lens correction and CA removal was on.  I don't see that they need sharpening.


100mm L at 5/5.6


Canon General / Canon Refurb Lenses and bodies 15% off Now.
« on: March 25, 2012, 08:40:44 PM »
I just received a e-mail notifying me of the Canon 15% off sale for refurb Bodies and Lenses.
Promo Code SLRF15, or for lens LNSF15 Powershots PSF20 (20% off).
Only one item per order with code,  enter separate order for a lens and a body.  $5 flat rate shipping, but you must pay any applicable sales tax.

What does a person have to pay for a Nikon D800 to match a Canon setup?  I've taken a Canon 5D MK III lit with the 24-120mm L lens and top of the line flash versus the closest that nikon has to offer.
Here is the list.
Here are some prices of similar packages. You can argue about quality, but they are top of the line with similar specs.  The secret is that Canon includes items in the package that Nikon Charges you for separately.
Nikon D800
Body -                           $3000
24-120 lens -                  $1296
Nikon SB-910-                 $547
Nikon Camera Control Pro   $146
Nikon Capture NX2            $135
Total                              $5124 (Correction) :)
Canon 5D MK II
Body with lens kit                     $4300
24-105mm L (included in Kit)       $0
Canon 600EX RT                       $630
Canon Camera Control Software   $0
Canon Photo editing Software      $0
Total                                       $4930
Some may ask: What happens when you need service?  Nikon is refusing to sell parts to the hundreds or thousands of small local camera repair outfits.  You must send your camera to nikon or a authorixed repair station and pay big prices.  They get you coming and going.

EOS Bodies / How to Edit 5D MK III Raw files in Lightroom(Windows)
« on: March 22, 2012, 05:01:27 PM »
Note, it has been pointed out that sone users (Ones I trust) have found that DPP is producing soft images.  Rather than recommend it, I am going to rewrite the process to explain how to use the RC1 version of Adobe DNG converter until we find out whats going on with DPP.
Thanks to those who posted the link to info about DPP.

You have your new Canon 5D MK III and want to edit the raw images in Lightroom.  Since Lightroom does not yet support CR2 files from a 5D MK III, here is a alternate method. 
Note, If you use Adobe Photoshop, install the Adobe Camera Raw 6.7 RC1 here:
Your camera came with DPP, EOS utilities, etc, but experienced testers have found the first version of DPP to produce soft images. so here is a better method than using DPP.

This is a abbreviated process on how to get the images into lightroom using Adobe DNG.  It is a release Candidate version and subject to change, but users, including myself have had good results.

  • If you haven't already, download Adobe Digital Negative Converter 6.7 RC1 here:   Click the accept terms box and a list of versions will appear.  Select Adobe DNG Converter for the computer you use. (Do not select Camera Raw for use with Lightroom, it works with Photoshop).
  • Install the software
  • Transfer the cr2 images to your computer using the utility of your choice.
  • Open DNG Connverter, select the folder with the images. As far as I know, you must convert all the images in the folder, jpeg images will be ignored.
  • Select or create a save folder, it can be a different or sub folder from that holding the original cr2's.
  • If you wish to create a new name for the files, you can do it here, but be careful, or you will lose the correlation with the original cr2 file numbers.
  • Advanced users can create their preferences.  Be aware that some of the preferences can greatly increase fole size, or make smaller files that have lossy compression. The default settings are a good place to start.
  • Click Convert

  • Open Lightroom and import the dng images as you would any other image.
  • At this point, you are editing what amounts to a raw image in Lightroom and can export it to jpeg, etc for upload to your web site.
    Good luck

EOS Bodies - For Stills / DPP 3.11.10 and DLO Module
« on: March 17, 2012, 10:53:36 PM »
Lots of us are interested in the new DPP 3.11.10 that arrives with the 5D MK III.  It is supposedly going to allow a much broader number of optical corrections than past versions, so I am wondering how it will compare to third party software from Adobe, DXO, and so on.
I found a link to some images processed with the new DPP, and there is a very noticible improvement.  What we don't know, however, is how well it will work on our images, or even if the three cases were the best of 1000 attempts, for example.
Still, here it is, for better or worse.
