Things to Consider When Choosing a Lens

Aperture (f-number) – Lower f-numbers (e.g., f/1.4, f/2.8) are better for low light and background blur.
Image Stabilization (OSS) – Helps reduce blur in handheld shots, especially useful for video.
Weight & Size – Some lenses (like G Master) are heavy; consider if portability matters.
Budget – Tamron and Sigma offer great alternatives at lower prices compared to Sony’s GM lenses.

FAQs

What type of lens mount does the Sony A7III use?

The Sony A7III uses the Sony E-mount system. It is compatible with both:
FE (Full-Frame) Lenses – Designed for full-frame sensors (best for A7III).
E (APS-C) Lenses – Can be used, but the camera will crop the image to match APS-C size (1.5x crop factor).

Can I use Sony APS-C lenses on the A7III?

Yes, but the camera will automatically enter “APS-C crop mode,” reducing the resolution from 24MP to around 10MP. If you want to use the full sensor, it’s best to use FE lenses.

Does the Sony A7III have in-body stabilization (IBIS)?

Yes! The Sony A7III has 5-axis in-body stabilization (IBIS), which helps reduce camera shake. However, using lenses with Optical SteadyShot (OSS) can further improve stabilization.

Can I use Canon lenses on the Sony A7III?

Yes, but you’ll need a Canon EF to Sony E-mount adapter (e.g., Sigma MC-11 or Metabones V).
Autofocus might be slower, especially in video mode. For best performance, native Sony lenses are recommended.
