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

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.

Thanks

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.

Thanks

Lenses / How to Calculate DOF for a 180 Macro Lens (in macro mode)
« on: May 12, 2014, 10:57:40 PM »
I am interested in how to calculated DOF with a 180 macro lens so I can determine how much to move a focusing rail.  If the focal length was truly 180, then it would be simple.  But I have heard when a macro lens is focusing close, the focal length is actually much shorter than when the lens is focusing at infinity.

Canon General / Professional Business insurance
« on: April 23, 2014, 11:37:23 PM »
There have been several (at least, perhaps more) on equipment insurance.  What about business insurance (professional liability).  If someone get hurt by your equipment, etc. I don't want to be held personally responsible.

Any suggestions?  I am think of doing a bit of work, not full time, but never the less, what to make sure I am covered.

Software & Accessories / Looking for a focusing rail
« on: April 02, 2014, 12:39:08 PM »
With spring nearing, I am thinking that I would like to get use a focusing rail to help my macro work.  Ideally it would be great to have a motorized setup, but with the need for power (batteries) that would make the rig too large to take to the field.

Next best would be a stepping rail with some sort of gear knob to allow me to move the camera in fine increments.

Any experience/recommendations? 

Thanks

Software & Accessories / any records to raw to both cards?
« on: March 12, 2014, 04:36:33 PM »
Hi

Does anyone record raw to both cards simultaneously?  This would give a bit of extra security in case a card failed, but seems like over kill since I have yet to have a card die in the field.

EOS Bodies - For Stills / HELP - strange 1Dx AEB behaviour
« on: February 16, 2014, 12:32:35 AM »
Or at least I think it is strange

I set my 1Dx to AEB (firmware v2.0.3) in manual exposure mode.

According to the manual, the camera should adjust the shutter speed.  What I observed is that the camera adjusts whatever is on the main dial.  When I have the aperture control on the main dial, it is adjusted.  When I have the shutter speed on the main dial, it is adjusted.

Is something wrong with my camera/firmware or is the quirk in the firmware?

Thanks

Hi

I am considering buying a high MP body for landscapes.  Right now Canon does not a high MP body (5DM3 is 22 MP), not quite high MP.

As i see it, there are 2 high MP 35mm bodies - Nikon D800 and Sony alpha A7R.  I think both use the same sensory though there is a difference in cost - the nikon is 3300 vs 2300 for the Sony.

I think it will be easier to attach a canon lens (such as the 17mm T/S) to the Alpha as well as attach the Nikon 14-24 to the Alpha (is this true) than the Canon 17mm T/S to the Nikon.  Is this true?

Other lens to consider?  With the Nikon 14-24 is there any reason to use the Canon 14mm?

Other thoughts are welcome.

Thanks

Lighting / Technical specs for Canon 600 flash
« on: January 21, 2014, 11:29:00 AM »
Looking to understand how my flash works.  Like how does high speed synch work in detail- for example, what is the number of times it flashes at different shutter speeds, why does it go into high speed synch at 1/250 in Av mode but not M mode.
