The Minolta MD 75-150mm f4 was released nearly 40 years ago but still it makes a good argument for a category of lenses which has nearly died out: Zooms with a limited range and slower speed.

After analyzing the infinity sharpness of the candidates in Part 1 of this series, we are looking at the opposite direction of the focus ring. For a versatile do-it-all standard zoom lens, the macro capability is an important factor of the overall performance. Details in documentation-, wedding-, product-, nature- or food photography are typical applications for a standard zoom as a pseudo-macro. In photographic history, the macro feature of zoom lenses was often a shameful marketing trick without any serious usefulness. Let’s check out the performance of the of the Sony FE 2.8/24-70 GM, Tamron 2.8/28-75 Di III RXD and the Sony FE 4/24-105 G OSS.
Standard zooms are the swiss knifes for photographers who need flexibility, can’t change lenses or prefer exact framing over prime qualities.
The Sony FE standard zoom palette has grown in the past years. In the beginning, we were cought between a rock (Sony FE 3.5-5.6/28-70) and a hard place (Sony FE 4/24-70 ZA OSS). We were trying to get around this lens type as good as we could.
In 2019, three great options are available and the situation is the other way around. Not only I have a hard time to decide which of the three highly regarded lenses suits me best, so let’s find out together which lens is the best choice for whom.
This article will be split into three seperate posts due to the sheer amount of information. I will start with a sharpness shootout (infinity) between the Sony 2.8/24-70 GM, the Tamron 2.8/28-75 Di III RXD and the Sony 4/24-105 G OSS.
