I thought it was me too! Now I'm trying to decide......do I buy the Mark III or switch to Nikon.

[quote=&quot;MelanieSikma&quot;:1kia8m3p]I don't know when you bought it but I really think I had a lemon.  I sent it in a couple of times and they found something wrong supposedly both times and fixed it but I never saw an improvement in the focusing.  I sold the thing and actually switched back to Nikon which is what I was shooting when I first started.  I still use my old 5D though as a backup and that is working just fine.  I was starting to doubt my skills as a photographer with that Mark II and so I couldn't just buy a new one because I had no confidence in the camera.  I now feel confident going to sessions again knowing I'm going to get the large majority of my images sharply focused.[/quote:1kia8m3p]
