I bought this lens because I wanted two things: a step up in quality from my Sony 28-70mm kit lens and a greater focal range for travel. Although this lens adds quite some weight to your bag, the results are worth it.

Good Build Quality; Great Picture Quality

Bulky

Overall the Sony FE 24-105mm f/4 G OSS is an obvious choice in the Sony lineup. It may not be able to touch the center quality of the Sony FE 24-70mm f/2.8 GM but the border quality is surprisingly high for such a lens - at least when stopping down to f/5.6. Lateral CAs are moderate.

+ Consistently sharp at all focal lengths; + Fast; silent autofocus; + Relatively compact and lightweight; + Impressively resistant to flare

The Sony FE 24-105mm f4G OSS is a general-purpose lightweight zoom for Sony's full-frame mirrorless cameras upon which it'll take you from wide-angle to short telephoto. The lens sports a constant f4 focal ratio and can deliver reasonably blurred backgrounds and attractive rendering when shot...

Sony's FE 24-105mm F4 G OSS zoom is pricier than similar lenses for other systems, but it's also a better performer.

4.4x zoom range; Constant maximum aperture; Fast focus; Image stabilization; Light and compact; Dust and splash protection.

Expensive; Dimmed corners when corrections turned off; Some edge softness at f/4 when shooting at wider angles.

So far, I’m pretty lukewarm about the new Sony 24-105mm f4 G OSS. Does it have a whole lot going for it? Absolutely. However, I’ll need to test it with finalized firmware and all to ensure I get the best results out of it.
