Focusing
Jan 9, 2019 12:54:28 #
I shoot with a canon 7DMarkii with Tamron 150-600 lens. I’m shooting out my car window while driving thru a refuge. I rest my camera and lens on a bean bag or other prop on my window ad shooting auto focus. With my eyesight I can’t really see if my subject is in focus even on auto. I get home and load photos to my IMac and a whole lot are out of focus. Anything I could try differently? Please help with suggestions.
Thank you.
Thank you.

What are you usually choosing for aperture (depth of field) and shutter speed (motion blur)?
Do you shut off the car engine? Something that happened to me: the car's exhaust got in the way
And you have possible vibration issues. More: gravel roads = dust, paved roads = heat rising on hot days.
Post a couple of photos in this thread, please. Use "store original."

I would have the same questions. Can't tell without more info.

One thing to be careful of when shooting on a beanbag is that moving the camera doesn't move the focusing ring. My Nikons will allow manual focus to override AF. So if the focusing ring is in contact with the bag, just pointing the camera slightly right or left can override the AF.
Some lenses have a setting that gives more preference to AF. What that means is that slight movement won't change the AF setting, but eventually manual focus will take over.

Am I guessing correctly, that you let the camera find focus? That maybe the issue. Could you move the focus point before pressing the shutter? Are these stationary animals? The idea is to have the eyes in focus.

I do shut the car off and the birds are usually perched in a tree. I start with F-8 and 1250 shutter speed. On some shots I’m fairly close. I thought there is a setting on the lens that may need to be changed. I also use BBF.

Please post an example JPG file, straight from the camera (or converted from RAW with no adjustments) and be sure to store the file. We can analyze the image in Canon's DPP and give you very detailed and actionable suggestions. Without the details available from an EOS-created image, we're all just giving our best guess.

Jerry, can you return to the camera / card and offload an original jpg file from the camera and attach that original file? The Apple processing of this image has stripped all of the EXIF data, including the exposure information.

Jerry,
Some lenses have a focus limiting switch that can keep the lens from focusing close. It's purpose is to keep the lens from having to go through its entire range when focusing on distant objects. I had one years ago than could even keep the lens from focusing beyond a certain distance when working close.
Check your lens and/or the manual.

Is your car running when you shoot? Even slight idle will vibrate the window edge and/or the door. Especially using a telephoto. I shoot hand hold with the window down and the car turned off without an issue. But I do not own a Tamron 150-600, I use a Nikon 200-500 with a 98% keep rate.

You forgot to read the thread before responding.

Be sure to have the camera in servo mode and your f stop is high enough for dof (focus depth). Singe point focus for specific target...

Good morning,
When my husband and I go to the drive thru refuge we are very quick to turn off the engine. Longer lens shows any movement even at higher shutter speeds wit the engine running. We designed a "Window Pod" for when we stay focused on a bird for a long time waiting for take off and such. With limited movement from a car it helps so much with stability. The arms get tired after 6 hours of shooting with a heavy lens! Car off, fast shutter speed and that should fix it. Everyone is always checking it out our design, kind of fun!
