The constant f4 aperture is a bonus for filmmakers, as they quickly zoom in and don’t have to compensate for changing exposure. Mainly because of its reach and flexibility. Like its more expensive f2.8 pendant, the RF 70-200mm f/4L IS USM is the go-to zoom range for many photographers and filmmakers. But I think for the money and considering its size, the lens is going to be no-brainer for many RF-Mount camera owners. Tests will tell if it will have its place in many a photographers’ bags or not. The Canon RF 50mm f/1.8 STM is a relatively cheap lens.

These include aperture, ISO and exposure compensation. The aforementioned control ring can be configured to adjust a variety of exposure settings. The Diaphragm-blades are rounded, which should help with achieving a nice, round bokeh. The maximum aperture of 1.8 gives photographers and filmmakers a shallow depth-of-field and good low-light performance. The AF can be overridden manually by using the Focus/Control ring. The STM (Canon’s designation for STepper Motor) provides swift and quiet autofocus.

The field of view of a 50mm lens on a full frame camera makes it a nice always-on type of lens that is suited for many photography scenarios. Let’s have a look at the first offering: Canon RF 50mm f/1.8 STM The Japanese company introduced two more full frame lenses: A semi-professional 50mm f1.8 and another classic focal length – the pro-level 70-200 f4 Zoom. Imaging giant Canon is quickly expanding its range of RF-Mount lenses. Tamron 28-75mm F2.8 Di III VXD G2's optical formula consists of 17 elements in 15 groups.By Florian Gintenreiter November 5 th, 2020 Tamron 28-75mm F2.8 Di III VXD G2 is a fixed aperture lens with a constant max aperture of f2.8 from 28mm all the way to the 75mm. Tamron 28-75mm F2.8 Di III VXD G2 has a Max Magnification Ratio of 0.37x and has a minimum focusing distance of 0.18m. The disadvantages of this design are being harder to seal against dust and moisture, weight balance shifting while zooming and zoom creep in certain lenses. This makes it possible to design the lens with a smaller minimum length ( generally when it is zoomed out) compared to internal zoom lenses. Tamron 28-75mm F2.8 Di III VXD G2 features Rotary (extending) zoom method where the length of the lens changes as you zoom in or out. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides an 35mm (FF) equivalent of 42 - 112.5mm. Tamron 28-75mm F2.8 Di III VXD G2 has a focal range of 28-75mm and 2.7X zoom ratio. Max sensor coverage of Tamron 28-75mm F2.8 Di III VXD G2 is 35mm FF. Some of the latest released cameras that are compatible with the Sony FE lenses are Sony A7 IV, Sony ZV-E10 and Sony A1. Tamron 28-75mm F2.8 Di III VXD G2 is compatible with cameras that have Sony FE lens mount.
