Un obiettivo molto interessante, con una gamma di focali che lo rendono estremamente versatile da un buon grandangolo fino ad un buon medio teleobiettivo. Qualità ottica ottima al centro, buona ai bordi anche se per avere maggior uniformità serve chiudere a f/5.6, non superlativo tuttavia nel controluce. Ottima costruzione, stabilizzazione ottica e basse aberrazioni. Prezzo piuttosto alto.
It’s the best-judged general-purpose zoom Sony has yet made. Impressively sharp, not too bulky, weather-resistant and with a really useful zoom range, it ticks all the right boxes. It’s not as affordable or petite, but its extra telephoto range is oh-so-useful, while the addition of an AF hold button along with focus and IS mode switches are great for usability.
Balancing price, weight and quality, the Sony 24-105 is my favorite general purpose zoom for the Sony system. Compared to the Sony 24-70/2.8, you are getting more range as significantly less weight and lower price, while still getting fantastic image quality. Optically, the lens is superior to the Sony 24-70/4 and variable aperture 28-70.
It performs very well indeed on a technical level, but also produces clean, sharp, smooth images that give overall an impressive aesthetic result. If anything is a bit weak it is the CA performance, although that can be corrected for those images that demand it.
Ken Rockwell This Sony FE 24-105mm f/4 G OSS is the world's best midrange zoom. It offers spectacular optical performance as well as first-rate mechanical construction at half the price of similar lenses, and it's smaller, lighter and has better ergonomics than the more expensive lenses. It is a superb lens at a reasonable price, a weather-resistant baby version of the huge 24-70mm f/2.8 GM.
The border quality is surprisingly high for such a lens - at least when stopping down to f/5.6. Lateral CAs are moderate. The quality of the bokeh is quite good for a lens within its scope. Image distortion and vignetting are usually taken care of during post-processing [...] The build quality of the lens is very good [...] The AF may still not be as fast as on modern DSLR lenses but it's good enough for the majority of applications [...] This is a big lens really.
