Can i assume then that both lenses are sharpest with MFA of 0?  The auto Focal test for the 85, shows that it needs a +4 adjustment, which is not what the above graph show...

I am also attaching two more examples with my 50 1.3 at 0 and +3 microadjustment

I am attaching the two graphs. The 'smoother' graph with the highest numbers at the largest apertures is the one with 0 microadjustment.

The latest version of FOCAL Pro includes an aperture sharpness test. I used it with for my 1DX and both 50 1.2 and 85 1.2. I run these tests with different AF micro focus adjustment settings. Can we assume that the micro adjustment settings with the highest numbers graphs, are the best ones? In most cases these settings did not agree with the results of the FOCAL auto calibration method.

Thank you...

EOS Bodies - For Stills / Using 1DX in very low temperatures
« on: December 08, 2012, 06:22:36 AM »
Dear all, I will be visiting Moscow next week, and temperatures are extremely low (around -10 to -15 degrees C or 14 to 5 degrees F).  I am wondering whether I should get my 1D X with me. Is there a chance to cause some damage to the camera or lenses? Thank you..

Software & Accessories / Canon presets for Lightroom 4.1
« on: October 01, 2012, 01:42:54 PM »
Although DPP is rendering RAW files very nicely, it has limited functionality and not ideal for handling large number of files. Its also extremely slow on MACs (due to a known problem managing folders with over roughly 400 images). I am seriously contemplating the possibility of switching to Lightroom 4.1. After first trials, it looks that RAW files are rendered in a different manner than DPP. I have tried  changing some of the adjustment parameters, but I have not managed to make them look similar yet. Do you know of any reliable Canon presets I can use to make them looking similar?

Thank you.

What do you mean by another set for manual AMFA with FoCal settings Neuro?

I have also been a great fan of PCs since the beginning. I have started using MACs I the last year, and I am a convert now. They are super fast, stable and just fun to use!

After doing a lot of tests using both the Mac and PC versions, I think I have managed to identify the cause of the issue. On the MAC version DPP has a problem handling folders with over around 400 images in them. It seems that there is a memory management issue. On the PC version, it does not appear to be a problem.

As I mentioned on my first email, I do run a very fast MAC, with primary disk a 256 SSD and a 2TB secondary hard disk. I will recheck the installation to see if DPP is installed on the SSD. I have not upgraded to Mountail Lion yet, waiting for any incompatibility issues to be resolved. DPP runs fine, its just noticeamply slower than the PC version of DPP that runs on the same MAC under Parallels. More specifically, every time I exit the photo EDIT window (I process RAW files), the programs takes around 6-8 seconds to come back. On the PC version, this is almost instant (maybe around 1sec).

I have tried all above suggestions, but none seem to accelarate the MAC version at all. Its seems to me that its the way DPP for MAC manages memory. Has anyone contacted Canon abour this?

Thank you very much for your suggestion (retain sort order). Unfortunately, its doesn't seem to make any difference in the Mac version, although I also tried it in the PC version (which I run under Parallels) and it has accelerated it even more. The folders I am using contain in excess of 400 files...

Software & Accessories / DPP for MAC too slow?
« on: August 29, 2012, 06:13:32 AM »
I am trying to use DPP on my new iMAC (i7 3.4GHz, 16GB RAM, 256 SSD, 2 TB hard disk, 2GB graphic card). Unfortunately, every time I access the folder view + thumbnails its taking a while to refresh the screen, and if I exit a photo edit window it takes even longer to come back. On the same iMac I am also using Windows Parallels, and I installed DPP for PC for comparison. Everything runs very fast.
Is it a problem with my settings (I use DPP high quality view option on both systems) or the DPP for MAC is not well written? Thank you all.

Lenses / Experience using the 28-300L?
« on: August 20, 2012, 05:30:29 PM »
I am thinking about buying this lens for one-piece solution for travelling photography. What is your experience with this lens? Its quite a old model, but still unique in its capabilities. Thank you for your time.

Warm thanks for the clarification Neuro. I guess I misread the instruction. I have also assigned this function to M-Fn2 button. I guess I have to try to see how easy is to use it in action. May I also ask what is your preferred buttons configuration? Warm thanks. I am thinking of assigning RAW/JPEG switch to DOF, and ISO setting to the SET button... I have also assigned  *H to the * button.
