Sigma 90mm DG DN Prime Lens Review
In this lens review Mark look at how this Sigma 90mm lens has been designed to appeal to photographers looking for a lightweight alternative to the many larger and heavier f/1.8 and f/1.4 options that are out there.
Mark shows multiple ultra high-definition examples he captured with this lens over an extended review period.
This lens review was not sponsored by Sigma and Mark purchased his own copy of the lens to make this lens review video.

$Sony FE 28-70 F2 GM Lens Review A wide aperture Standard Focal-Length Zoom Lens is a new design-concept for Sony. The lens offers the photographer the F2 wider aperture, normally only seen on prime lenses, but with the flexibility of using a zoom (eliminating the need to constantly switch focal length lenses). This will allow the photographer using this F2 G Master zoom, the ability to more easily create figure/ground separation or increased background blur (bokeh). Designing an F2 zoom has added weight, over-and-above an F2.8 zoom, but Sony has managed to keep this lens to a fraction over 2 lb or just below one Kilogram in weight. In this review I compare its optical performance with three of Sonys F1.8 prime lenses (stopped down to F2). This exercise demonstrates that it is possible to build a no-compromise wide-aperture lens that can out-perform a prime lens across its entire zoom range. This review provides the photographer with the information so they can make an informed purchasing design and to choose a workflow that best suits their needs.
