Lenses / Combining Roger's test - Canon 11-24 vs Nikon 14-24
« on: February 27, 2015, 07:56:31 PM »
I took two test Roger did and combined the charts.  Hope this is legit (tests were done the same way) and I am not stepping on anyone's toes.

Thought I would share what I found.  Note perfect match as far as focal lengths go (except for 24).  Not sure if Roger tested the Canon at F4 and Nikon at F2.8 - I think he did.

My observations: at 24 Canon is sharper (if MTF means sharper) until the very edge.

No direct comparison at 14 but can compare Canon 11 and 16 to Nikon 14.  Not sure what to make of these charts.  What do they mean to my images?

Third Party Manufacturers / thoughts on Sony A7R / any tricks
« on: February 27, 2015, 05:36:32 PM »

I have rented a Sony A7R with Metabones IV adapter to try it out on a photo tour next week.  I'll be using my canon lens for landscape and realize that AF will a challenge.  Only got 1 battery so hope this will work okay. 

If you have a A7R or tried it out, any tricks/tips I should know about it?

If I don't want to go to 50 MP (5Ds), how does this rate as an option?

Canon General / Lens stuck on the dock in California
« on: February 25, 2015, 07:14:43 PM »
I talked to my dealer today and he told me he is not getting inventory because shipments are stuck on the docks in California.

Has anyone else heard this?

If you have your 11-24 or know it is one its way, please share with the group.


EOS Bodies - For Stills / 5Ds or possible alternatives?
« on: February 24, 2015, 03:06:38 AM »

I am considering the 5Ds but before I pull the trigger I would like make sure that I am not missing anything.  Of course, we all know that the 5Ds is only announced so we can not compare IQ and DR to other cameras.  But assuming it lives up to reasonable expections here are my thoughts.

Do this make sense?

Alternatives: Canon 5Ds (5DsR), Sony A7R (or mark II if it comes out), and Nikon 810.

Image quality of the Sony and Nikon is excellent as is the DR.  Canon will top these in sensor size, not sure if IQ or DR will match Sony / Nikon.  I suspect that the IQ will be close, if not surpass Nikon / Sony, DR is unclear.

Lens.  This is were it gets touchy.  For the most part I think Canon glass is as good as Nikon glass.  Canon 16-35 F4 is nearly as good as the Nikon 14-24.  Canon 11-24 is unknown but, based upon price, is expected to be great.

24-70 edges goes to Canon.
TS - Canon wins.
70-200 F2.8 edge goes to Canon.
Macro - call it a tie (perhap edge to Nikon).

Unlike a year ago, Canon has caught up, especially in the WA/UWA glass.

With Nikon need to buy separate glass (extra cost), with Canon and Sony can used Canon lens (with adapter in the case of Sony - slow AF.  For WA AF is not as important.

1st choice is Canon 5Ds if IQ and DR match Nikon/Sony.
Otherwise Sony A7R.  Poor AF but uses Canon lens.
Nikon system is too expensive (will need to duplicate current lens), if I only carry 1 body, no backup.  Body is different than body I use on long glass.

Too early to call 5Ds and IQ/DR.  Hopefully Canon will make a great camera.
11-24 - too early to call.  Based upon price should be a world class lens.

Software & Accessories / Reco on travel tripod?
« on: January 06, 2015, 06:12:13 PM »

I am going with my wife (who will be at conference) to London.  I'll bring some photo gear (5D M3 probably without grip, 16-35, 24-70, possibly 17 TS-E and/or 70-300 L). 

Looking for a light weight tripod w/o center column.  Ball head most likely be Acratech.

Thanks in advance


I just my 7D M2 and really like the option to have multiple My Menu tabs.  It would be great if Canon would add these to their existing cameras (1Dx, 5D M3, 6D, 70D).

A couple of observations - I can not figure out how to turn of unused metering modes.  I only used evaluative and spot, never use central weighted or ....

Also found that they focus was a bit soft with my 200-400.  The camera arrived Wed and Thursday I took it on a family trip (mostly shake down).  I did a bit of AFAIM (I think +7 at the long end of the lens), with my 1Dx I don't need a AFAIM on this lens.

I have not had time to test other lens on this camera yet.

Software & Accessories / No LR 5.7 version for CC (yet)
« on: November 19, 2014, 07:20:17 PM »
I used the link to upgrade my LR CC (on Mac) and found that I had provide serial number to activate LR 5.7.  I uninstalled it and reinstalled the latest version using Adobe CC ap manager.  Got LR 5.6 installed and when I checked for an update there was none.

Wonder if there is LR 5.7 for Win and when the LR 5.7 CC mac version will be available.


I am considering upgrading to Yosemite (OS X ?).

Any software gotchas?  I run LR, PS both CC, bunch of plugins.



EOS Bodies - For Stills / Strange Problem with 1Dx
« on: October 15, 2014, 07:05:52 PM »

last week I was shooting a series of bracketing images (Raw, HS motor drive, +/- 1 stop) for HDR.  Occasionally on the 3rd image my 1Dx would freeze up and not finish the shot.

I fixed this by turning off the camera.  The battery was okay (>50% charge, perhaps 75-80%), and this did not happen on all the shots.  The shutter speed for the first exposure was around 0.8 second.

Anyone seen this before?  I plan to take the body to Canon service center but thought I would check to see if this was a known problem.


Software & Accessories / Settings for Reikan Focal
« on: September 11, 2014, 06:27:41 PM »
I am starting to adjust camera bodies with lenses

Wonder what settings in the preferences are recommended.  I tried high strict AF repeatability and found that was problematic.

Any recommendations?  After basic tests, what would be recommended next.  I got the pro software.

Lenses / When will we see a replacement for the 100-400?
« on: September 09, 2014, 09:15:55 PM »
There have been lots of talk of a 100-400 replacement and yet nothing has materialized.  When might we see this lens?

I have all but given up hope that it will be replaced.  After all, it is Canon's top selling lens and if they made it too good it would hurt 200-400F4 sales  :o

Lenses / Why are Cine Lenses so expensive?
« on: July 30, 2014, 12:28:51 AM »
Besides that they sell for the price, what does a Cine lens offer than a regular L lens does not?

Flip side - could a Cine lens be used as a still lens?  How sharp would it be?

Third Party Manufacturers / Anyone own both Canon and Nikon
« on: July 07, 2014, 12:49:45 AM »
In particular I am considering the new D810 with 14-24 and 24-70 for landscapes.   

The Canon 16-35 F4 is good but the 14-24 is great!

The 5DM3 is a nice camera but lacks the DR of the D810.

Hate to spend the extra $ for another body and duplicate lenses.

Does anyone shoot both Canon and Nikon - Canon for long lens and Nikon for wide angles?  Experience?  Thoughts?

I am not trolling nor trying to start a flame war, but look for well thought out positions based upon experience.



Lenses / Canon EF 16-35 F4 is shipping today
