Autofocus and exposure tracking can be constrained at faster burst rates, even if single-frame operation works.
Make the exact-model decision
Read the camera's burst-mode footnotes for the exact lens or mount adapter. Record the body’s sensor area, lens image-circle designation and exact still/movie mode. Check each focus and stabilization function separately.
A manufacturer example
Sony’s LA-EA5 page distinguishes still AF support on selected bodies from its explicit lack of autofocus during movie recording. Use the linked page for its stated model and revision; a different model may need a different support document.
Where to draw the line
Crop mode narrows the recorded view without changing the focal length printed on the lens. A still-AF statement may say nothing about movie AF. If a source does not address the exact feature you need, record that feature as unknown rather than treating silence as support or incompatibility.
Your next step
Take the model code from the body or lens label, open the official source below, and compare its scope with the equipment you have. Then use the test an exact pair to organize what is known. Do not mount an item that resists or appears on a maker’s exclusion list.
