7D Mark II - Focus Discussions

skid00skid00 wrote in post #17810295
Imagine that the AF locked on the light/dark/light band in the water, behind the bird. That band is moving. What if there was another band, before this one, that appeared to be moving toward the camera. Servo might have 'tracked' that band, and focused in front of the bird, extrapolating that that is where the band would be when the shutter fired.

Keep in mind that we have NO idea what light/dark pattern the AF chooses. We also don't know it's pixel pitch, so even though we tend to focus on the neck pattern in the bird, that pattern might be too small for the AF to see.

Don't forget to toss in the reported facts that the focus point may not be exactly where the visible square and it may be much larger. It's a miracle anyone can get a good shot of a small object. On the upside my focus test at 20% of FL gave me something concrete I could work with. Looks good so far, just need the weather to cooperate on a day off to really test it.

Congrats Jeff.

I saw exactly that effect in the last few days. I was getting a lot of back focused shots. When I looked more carefully through the view finder I could see the focus jumping from the bird to the wave behind. This was in AI Servo. As I was using BBF I just bumped the focus until I definitely had the bird and then released the button. I then had a much higher hit rate.

Thanks Peter, I guess ill need a new camera to continue down the road to publication, They say my camera is within spec and its all in my head lol ,...funny But they can help me figure out how to use my camera lol.

This is the look I had on my face

I'm expecting a similar answer, but I hope I'm just paranoid. I've been pretty careful not to be too critical of the 7D2 in other threads. I've tried to restrict my comments to this thread. I won't be able to sell my 7D2 to anyone else unless it's performing like it did originally. That means I'll be out $1900 because I paid the nerd tax by being an early adopter.

ya were kinda in the same boat, I'm still ok with having the last year with my 7DII, lol they did a customer menu reset lol well I cant say right here what I think of that IMAO like really... If anyone form Canon is listening >>> REALLY !!!

I hit the ground running, with your advice and the advice from others here on POTN. I was having so much fun and getting so many keepers, it made every trip out so worthwhile. That's the sad thing. If it weren't so good right out of the box, I might not feel as disappointed as I am now.

I'm finally through with the house prep stuff that has occupied my days off... and no rain for the next few days so I'll be out there getting more comfortable with my 1D IV. I have to say, I love the way it handles color. It seems to capture exactly what I'm seeing... which is nice because though I can see color, I have no idea what the colors are most of the time. I don't mess around with colors unless my wife is directing me. So the 1D IV might end up being a real winner for me...... I just hope the 7D2 gets fixed so I can sell it.... for quite a loss, I'm sure.

I'm posting 7D images in protest lol ....sorry to all those reading this stuff

I love this sauce I always put this in my Pho.

You got your camera back Jeff?

LOL Thanks Peter

I think each new camera from Canon should be gifted with a free bird or animal, they should give 7DII with a free FOX.

Nice shots, enjoying the images more than the issue discussion.

Ha thats awesome, ....Wait ,.....yours didn't lol How about one of the first images from my 7DII that is in Canadian Geographic Dec issue this month. I shot it back when I was grinning from ear to ear and the 7DII smelled new .....and Ya he's right in the middle because thats where he belongs,..... O and it focused like a champ

Jeff,
Don't let then off the hook.
Tell them to actually take some pictures at distance outside, servo, for you to see, and even confirm it is fixed, or point out the problem, to them Before they return your camera.

Wow, after all your trouble.

yesterday ordered a canon 7D mark II to replace my 7D that I am giving to my college age son that is taking a photography class. I had no real plans of upgrading my 7D as it was doing an excellent job for what I use it for which is my kids sports, parties and some portraits. I had planned on buying my son a refurbished SL1 but a good friend gave him a 35MM film camera and he has been using it a ton for street photography projects for his class as well as developing his own film. My wife suggested I upgrade and give him my 7D. I have been watching this thread closely and to be honest almost did not order the camera, but I remembered when I upgraded to the 7D from my 50D I had a small learning curve, but it looks like there is a steep learning curve with the Mark II, as well as a few possible dud bodies in the wild. I am going into this with a open mind and will keep everyone posted as I step through this new adventure.
