Hello Friends who made suggestions to me! So, yesterday I set up a test... I used both the Mark II and the Mark III and tested 4 lenses... the 16-35, the 24-70, the 50, and the 70-200.
I set up the camera(s) on a tripod, and set the focal length at the lowest and highest for the lens, and set the target 50X the focal length away. Set on One Shot focus, single point, center AF point. I shot two test shots, then moved the card and lens to the other camera and shot the same...then moved to the next focal length and moved the camera. The target was a yard stick. My mini cooper was behind it and I always focused on the number in the yardstick in front of my horizontal racing stripe. I made a mistake and set the ISO on 100 on the II, and Auto Iso on the III.
I'm reviewing the results and I'm still at a loss. The 5D Mark II was much softer (due to ISO 100?), but less in focus. Out of 16 shots at different focal on 4 lenses, over half of them were fuzzy. The 5D Mark III was perfect, although there was noise in the photo due to the ISO being around 1000 since it was a sunny afternoon...I was under a pop up and the yardstick was in the sun.
So, clearly, the 5D III camera passed that test as did all the lenses from that perspective. That is my working camera, and I'll have to check the Mark II out sometime. I can use the 7D in the meantime for my backup. But, it's still very worrisome!
So, could it be the auto focus, even though I tested auto focus on a tripod? When I took it to the camera shop and they updated the firmware, it reset the factory settings to default. Does anyone have any advise on additional testing?
Also, just looking at some of the bad images in both LR and on the disk in the 5D III when I was using the 70-200. One of the best images was a close up at f2/8 ISO 100 and 1/125 TV. Then the couple was walking towards me... and the images were all off in that sequence - like the autofocus wasn't working, and the metering wasn't working either.
The full sun was hot at 1:00, and they were walking under a tree towards me. Some of the images were full silhouettes and some were completely focused on the brush behind them even though the focus was definitely on her face. I double checked the focus points by looking at the disk in the camera and turning on the setting to show the focus point.
This was with the 70-200 IS F2.8 L. Evaluative metering, Shutter Priority. I've had that lens for about 5 years, and when I first got it I had to send it back for repair, but now sometimes takes beautiful images, and sometimes not, and so not sure if it's the AF in the camera, the Lens, the settings, or it's me! And I'm running out of time, because I have a wedding this weekend.
I think I will send the lens and the camera into Canon to get maintenance after this weekend. It's way less expensive than a new camera, and this one has 66,000 clicks, so it should be good for a while, right?
Can I ask what anyone with experience and knowledge using the Mark III and/or the 70/200 lens...
1) What AF point selection would you use for a couple walking towards you? I was using the 9 point, with the dot in the middle, Expand AF area: Surround. It was strange because some of the vertical columns were blinking, and i had never noticed that before, but I thought the focus would expand out to the guy as well as the girl...not sure about that?
2) What is the highest ISO you find acceptable?
3) What settings do you use on the 70-200 IS II lens? 1.2m or 2.5m? Stabilizer mode 1 or 2?
Sorry for the questions...it's hard for me because I live in a remote area, and although I took the course in professional photography through the NY Institute of Photography 8 years ago, there has never been anyone around to ask questions to or work with in person, so I've basically practiced and learned by myself or on line. There's no physical groups to join in my area, or friends who are photographers. So I appreciate the knowledge in this forum.
I did not drop my camera, as someone asked. And yes, the lens was set to autofocus.
Thanks in advance for anyone taking the time to answer and help me! Cheers!
