EOS Bodies - For Stills / Re: Back Button Focussing and AF Points
« on: July 09, 2014, 06:52:33 AM »
I use BBF all the time but i find a lot of times i have let go of the back button before pressing the shutter. In essence this is much like manually focusing and then i read this article which makes me wonder whether it is interfering with the metering (usually evaluative).
I guess the moral would be to not let go of the back button until you have successfully taken the shot?

Canon General / Re: DOF and Sensor Size
« on: July 01, 2014, 09:31:56 PM »
I had a lot of trouble wrapping my head around this too. I did read somewhere this explanation that made sense.
Cameras with smaller sensors have a larger DOF to a full frame because it is dictated by ACTUAL focal length, NOT EQUIVALENT. As an example on a compact @ F2.8 it's roughly equivalent to a full frame camera @ F11

I guess it would probably interfere with the Magic Lantern software that some of us have as well.

Lenses / Re: 50 F1.4 durabilty question

The focus ring on my 1.4 also got bent inside a suitcase . Any force whatsoever to shorten the lens will bend it and i strongly suggest permanently leaving a hood on there. I did find this web page and followed it to the letter to fix my lens myself and it worked. Allow yourself a couple of hours of time to do it however.

My understanding of it is that compact cameras have a larger Depth Of Field to a full frame because it is dictated by ACTUAL focal length, NOT EQUIVALENT. A 35 mm camera on a standard lens wide open is about 24mm. On a cropped camera it is about 18mm and on a compact somewhere about 6mm

Technical Support / Re: Hyperfocal Focusing Painlessly?
« on: June 29, 2013, 06:53:53 PM »
According to an online DOF calc
http://www.dofmaster.com/dofjs.html
The hyper focal distance at 19mm at F11 is 3.55 feet or 1.08 meters
I would however be looking at F16 which would make it 2.53 feet and 0.77 meters respectively or even F22

Under menu 2, (2nd from left)select-custom white balance. It will ask you which picture you want to import

This works for me on my 60D

Take a photo of a  white object (A4 paper ok)

Under menu 2, select-custom white balance

Import the picture you took and select ok

Under the second tab in menu, select-white balance-custom

After, DON’T FORGET return white balance to what it was originally on.

I went from a Pentax KX to a Nikon D7000. I now have both a Canon 60D and a 6D. I think that the Nikon nailed the exposures better in ambient as well as flash compared to my Canons which seem to underexpose by 1/3 to 2/3 of a stop. I am finding the flash on my Canons quite frustrating in ETTL as there doesn't appear to be much consistency in the shots.
I did however switch over because the photos just looked better on the Canons. The skin color is realistic on both of the Canons where as on the Nikon, was often sickly looking. Landscape photos also seem to look better on the Canons. From my limited experience, the Nikons seem to be better value but at the end of the day, its all about the photo.

Speedlites, Printers, Accessories / Nissin Di866 markII and HSS
« on: January 25, 2013, 04:03:44 AM »
I have a 6D as well as a 60D with a Nissan Di866 markII. I wanted to try out the high speed sync on both of my cameras. The Nissin website claims this model supports HSS and that among other reasons was why i chose it. I used to own a Nikon D7000 until i decided to go with Canon and with that camera, you enabled HSS via the body menu. I have only now realized  that Canon enable HSS via a button on the flash itself, and since there is no button for this on the Nissin flash, i was wondering if anybody had actually done it, and how?
Thanks in advance.
