Lenses / Just got new 17-40 f/4L packed with "EF lens" CD
« on: September 21, 2012, 01:47:50 PM »
Just got my new 17-40 f/4L lens to add wide angle capability for my 5D3.  Now I can go wider than the 24-105 f/4L kit lens.  Looking forward to running AF MA tests to see how it performs. 

A first for me: the 17-40 was packed with a "EF lens" CD that has PDFs of user's guides for all Canon EF lenses.  Saves Canon from publishing handy booklet size guide that can be easily stashed in my camera bag.  Lens User Guides don't always have much in-depth info, except for speciality lens, like macro, tilt, etc.  With PDF substitute, not as convenient as booklet size I've gotten with my previous lens purchases.  Another cost-savings move by Canon.

EOS Bodies / Re: New firmware to Canon 7D, v2.0.3

I updated to 2.0.3 and now every time I open the card slot or turn the camera off for couple of seconds, it turns my AF micro adjustment setting to disabled. It still remembers the adjustment value, but is not using it any more.

Out of curiosity, do you have Orientation Linked AF Point set to 1: Select different AF points?  I ask because the 1D X had a similar issue on firmware 1.0.2, which was corrected with 1.0.6.

I've updated to 2.0.3 and don't have any problems with either of these issues.   I have AF Microadjustment set to Adjust by lens and it doesn't revert to Disable when 7D powered off, or when CF card removed and restored.   Using either setting of Orientation Linked AF point does not cause AF Microadjustment to Disable.

Did you try re-installing 2.0.3, afterward being sure to then power off and remove and reinstall battery?

Flip flash like xxD and 7D?  Or does this FF prevent flip flash like others?  :(

Replacement lens that currently costs about same as 100-400.  At f/5.6 why would anyone want this lens?  Help me understand benefit over 100-400?

Just looked on Amazon at cost of Lexar 1000x 32GB card.  One card for $130, or a two-card pack for $300. 

Interesting that it is $40 cheaper to buy two copies of the single card than to buy the two-card pack.   ::) ?????

Macro / Re: Tulip with 7D and 100 f.4L macro

More of test.  In hindsight, additional shots at wider apertures would have been instructive for comparison purposes.   Still, wider apertures would have lowered the DOF, which I wanted to maximize in this case.  Lots of detail in this tulip that I found interesting.  The DOF trade at some point becomes an artistic choice, even considering some optical distortion - and not an absolute necessity.  :)

It seems I must have been asleep when I typed in the shooting info.... ::)   

Correct info is 7D with 100 f/2.8L macro, ISO 100, f/32, 1.3 sec.  Can view all this in EXIF info embedded in file.

The main point I was trying to make here was my desire for max DOF (f/32) and good IQ (ISO 100), which required somewhat long shutter speed (1.3 sec).  Fortunately, there was enough available light and no wind to do this. :)

Correction--- shutter speeds was 1.3 sec, not 1/3 sec.  Just a typo :)

I like your original shot with the star bursts.  It is much harder to get nice-looking star-bursts than to eliminate them by opening up the aperture.     

My picture is a sunrise when there wasn't much light, but I saw the opportunity to get a star burst of the rising sun AND its reflection in the lake.   Shot with 7D and 17-85 at 59mm at ISO 100 at f/32 and 1/20 sec.

Seems to me that the Lexar 1000x is UDMA7 compliant - but is the 7D is UDMA7 compliant? 7D certiainly is UDMA6 compliant, but I don't think v2 firmware made 7D UDMA7 compliant.   Even though the Lexar 1000x may be the fastest card available, the 7D may not be able to take advantage of the faster speed. :)]

I have been using SanDisk Extreme Pro 16GB cards on my 7D since they came out and have been happy with them.  Since upgrading to the 7D v2 firmware I  have notice some improvement in burst speed.

Software & Accessories / Re: Stitching panoramas question
« on: August 17, 2012, 03:00:07 PM »
I've done a search but can't find an answer to this question.
I'm going to try my first panoramas in a nice landscape area soon.
I understand the technique for taking the pictures ok.
Let's say I take 5 images in horizontal format to be stitched together. I'll probably be using Canon's Photostitch software.
How do you know what will be lost from the top and bottom of each of the 5 images when they are stitched together? Or can this be specified by the user?
I'm not talking about the areas of overlap that are needed, but the area at the top and bottom of each picture that will go in order to produce the long thin panorama.
I want to make sure I don't lose something that is integral to the composition.

I hope this makes sense!

Have you considered using vertical (portrait) format?  I think you have more control - more information in your final image - and less distortion - if you take your images in the vertical (portrait) format. :)

5D MK III Sample Images / Re: Boston Panorama

I like it a lot, especially since it's not an HDR effort - which is what I most likely would have attempted.  Wish I had been there to try.

However, the top floors of the left-most tall building are washed out, and a bit of an eyesore - hard to avoid without some HDR - or at least some highlight correction.  :)   

Liked you pics on photobucket.  Did you use HDR on any of them?

Four images of Navy's Blue Angels taken with Canon 5D Mark III and 24-105 f/4L.  Each image shot at 105 mm with the same exposure settings:  ISO 800, f/8, 1/3200 sec.  Really enjoyed the Airshow and satisfied with results even though limited by 105 mm max focal length.    :)
