This doesn’t sound right at all. I assume your AF was on "human" and the eye AF was engaged?
A few days ago, I took a series of pictures of a medium sized dog running really fast, almost flying, straight at me, using the Tamron 35-150 on A1, shooting at 15 fps. At least two-thirds of the pictures were in focus, that I accept as a very satisfactory performance for a 3rd party lens on a subject moving very rapidly toward the camera (yes, the 70-200 GM II, could do much better).
Your experience might be due to the lens more likely than due to a camera fault. If you have another lens available, preferably one with a proven ability to focus fast, you may want to repeat the test, to definitively rule out the camera as a source of the problems.

So ran this same test three this time paying attention to the shutter rates and other things a lot more and attempting to remove me from the equation threw it on auto and let the camera figure its thing out. ISO was very low(around 100) shutter speed varies slightly but most around 1/800. It's literally a very bright clear day out so should have no issues. I know I should probably do a mechanical shutter for this test but frankly, I bought an A1 to use the electronic so electronic shutter..
First Test The kid is in the center of the frame jogging at the camera while I pull back the zoom. Out of 10 pictures non were what I would term "sharp", 4 were good if you didn't pixel peep, and 6 were bad. Like totally out of focus. AF-C wide
Second test no pulling back zoom.. just taking pictures as said kid runs at the camera. 35mm when they are out far away it's not as sharp and as they get closer the sharpness improves dramatically till they are basically a foot or two away. AF-C wide
Third test no pulling back zoom.. just taking pictures as said kid runs at the camera. 150mm sharp starting out. As they get closer it becomes less sharp. Only 1 picture out of all of these wasn't clear. AF-C wide
I'm fairly certain there wasn't any camera shake in these.. I took them on my knees and generally held my breath to ensure even my breathing movement wouldn't affect the camera. I need to get my tripod out but just don't have a lot of time. Honestly though feels like the autofocus on the lens just can't keep up. I wish I had more lens to test with but I've not got them ordered yet. If I'm being brutally honest if the Tamron 35-150 goes on sale again at Amazon this is going back. It honestly might just go back anyways and I pay full price for the Tamron. If the subjects are still it does take very good pictures. My wife captured some very nice ones of my kid's when we were taking a walk with my father's dog. All of them were still though. The ones where she tried to capture my son moving were not clear. Hence why I started these tests to see if it was something she was doing or not. Though she is experienced in taking pictures.. Honestly probably more than me. She just doesn't have the time to mess with things these days.
Btw probably expecting to much out of this lens tbh but just guess wanted to post my findings.
If you're wondering why I don't post the pictures I don't feel comfortable posting pictures of my kids online. Sorry.. If I can find a subject(like my dad's dog ) to test with I'll post them up....Show more →
