Most of us never get the chance to really investigate what’s inside of a high end photography lens.
I know that I’ve never been brave enough to do real surgery on my gear, but I think there’s a lot to be gained from really getting an idea of the guts of your lenses. At the very least, it gives you new perspective and respect for your equipment.
The very first lenses ever created were single element units that were very quickly adapted for aperture stops so that they could actually maintain focus. After one hundred and fifty years of innovation, we were left with something that’s absolutely nothing like the original lenses of the early 1800’s. Fifty years after those lenses, the modern, autofocus photography lens is yet another massive jump forward.
The Sony FE 24-70 G Master Lens is one of those lenses that encapsulates all of those advancements in technology over the last few decades. And that becomes incredibly apparent when you start taking it apart, which is exactly what this Sony engineer does in this video.
The lens has ninety-three individual pieces, and the vast majority of those parts aren’t focused around the conventional mechanics we associate with lenses. It really shows you all of the ingenious design that goes into creating such a compact package—fitting that technology into one barrel isn’t an easy job.
Maybe after watching this, that $2,198 price tag seems a bit more reasonable.
Teardown of the FE 24-70 mm G Master Lens
Sony FE 24-70mm f/2.8 GM Lens
- E-Mount Lens/Full-Frame Format
- Aperture Range: f/2.8 to f/22
- One XA Element & Two Aspherical Elements
- One ED Element & One Super ED Element
- Nano AR Coating
- Direct Drive SSM Focus System
- Internal Focus; Focus Hold Button
- Zoom Lock Switch
- Dust and Moisture-Resistant Construction

A fast standard zoom favored for its versatility, the Sony FE 24-70mm f/2.8 GM is a wide-angle to short telephoto lens designed for E-mount mirrorless cameras. Featuring a constant f/2.8 maximum aperture, this lens maintains consistent performance throughout the zoom range and benefits working in low-light conditions and with selective focus techniques.
Complementing the apt light-gathering capabilities is an equally impressive optical design, which incorporates three aspherical elements and two extra-low dispersion elements. One of the aspherical elements features an XA (extreme aspherical) designation, ensuring its refined surface precision and notable ability to minimize spherical aberrations throughout the zoom range.
Additionally, a Nano AR Coating has been applied to individual elements to significantly minimize lens flare and ghosting for increased contrast and color neutrality. Pairing a sophisticated optical design and versatile speed, this standard zoom is well-suited for use in a wide array of environments and lighting conditions.
