## Questions & Answers

**Q: With aps-c lenses, does the video drop to 1080p automatically? it can't do 4k with those lenses i don't think. thanks.**
A: When recording 4K movies, [ APSC Shooting] becomes disabled and locked to [Off]. This means if you use a ASPC lens the camera will not auto crop if you set the camera to record is 4K. If you want to avoid vignetting then you will set the record to 1080 and then set APSC option to auto.

**Q: Does the a7s iii have an e mount? can i swap the lens from the a7 iii to the a7s iii without having to use an adapter?**
A: Yes the ILCE7SM3 is an E mount camera.

**Q: Can i mount zeiss sel24f18z into a7s3 ?**
A: Of course you can, it is an E-mount lens :)

**Q: Does this camera have an IR cut-off filter?**
A: Sony's commitment to customer satisfaction is our top priority.  Yes it does. Amy (Sony Social Support)
