EOS Bodies - For Stills / 5D Mark iii AF issues

« on: April 09, 2012, 03:37:14 PM »

I've gone through and tried af fine tuning.  Tried turning it off.  Etc.  Here's my issue with my 5d Mark iii camera that I want so desperately to love.  Maybe I have a dud?  I dunno? I will put the camera on a tripod, point it at a brick wall and focus and shoot, and sometimes it will nail it, and sometimes it will be dreadfully soft.  I'm using the center point.  I've tried all different focusing modes, and I'm shooting a very contrasty (should be easy to focus on) brick wall.  Again, it's about 50/50.  Sometimes it nails it.  Other times it locks on very fast, which is great.  I take the shot, zoom in and see how ugly soft the image is. 

The reason I'm even doing these test is I've taken it on two engagement shoots so far.  And have seen this issue.  There will be times when it will lock SOLID on exactly what I'm trying to focus on, I'll take the shot and it's awfully soft.  Other times it was doing great.  So I was thinking it was user error until I set up these very controlled tests shooting at a brick wall.  I'm shooting with nice L lenses as well.  Any help?  What would you do?  Would you send it in?  Would you return and just get a new one?

Lenses / Sigma 85 1.4 vs Canon 85 1.2L

I'm about to invest in an 85mm lens and I've heard amazing things about both of these lenses.  Is the 85L really $1000 better than the sigma?  I shoot weddings, and want that beautiful creamy look that is so famous in Canon's L primes.  Have any of you used both of these lenses?  What would you recommend?  Thanks!

EOS Bodies / 5D Mark iii focusing issues

« on: March 26, 2012, 12:50:17 PM »

Hi there!

I've had the 5D3 for 3 days and I'm loving it so far.  Despite one big major pitfall.  While the AF is lightning fast, it seems to produce soft images.  I had issues with 50-70% of my images turning out very soft, even in controlled conditions.  I decided to print out a focusing chart and see if my lens was back/front focusing.  Turns out in my test, it was severely backfocusing.  Corrected the probably (-15 af fine tune) and was in love with what I was getting with anything 4-8 feet away from me.  Then I took a picture of something further away, and now it severely back focuses.  As in, the camera/lens need the AF fine tune with close subjects, but not with far subjects.  So how do I calibrate for back focusing when I'm close to my subject, but then normal or front focusing when I'm far from my subject.
