Tamron 28-200mm f/2.8-5.6 Di III RXD: Zoom Test (4K)

Tamron's 28-200mm f/2.8-5.6 Zoom Lens for full-frame Sony E Mount is the world's first all-in-one zoom starting at f/2.8* for ultimate versatility. Tested on Sony a7iii, the following video/images will give you an idea on how far this lens can reach and how the amount of light changes as you zoom-in (especially indoors). Here is this lens' max aperture step down by focal length: 28-30mm = f/2.8 31-42mm = f/3.2 43-53mm = f/3.5 54-77mm = f/4.0 78-112mm = f/4.5 113-146mm = f/5.0 147-200mm = f/5.6 Check and play the raw files yourself: https://www.dropbox.com/sh/z8a4itr0pb... Zoom Test Tamron 28-200mm f/2.8-5.6 Di III RXD Video Settings: 4K 25p | 1/50" | ISO 100, 640, 1600 Photo Settings: Check the given exif Depending on the amount of available lights indoor, when shooting at the telephoto end, I would highly recommend to switch to Auto ISO (100-6400)*, use a tripod (to lower shutter speed on static subject/s), or use another light source (e.g flash, studio lights. etc). Otherwise, shooting at the wider end 28-30 mm is still f/2.8 and will be good enough to compensate in low light scenarios. Nevertheless, it's by far, very sharp for a super zoom lens. Offering the unique mixture of an all-in-one zoom range and a fast design, the 28-200mm f/2.8-5.6 Di III RXD from Tamron is a wide-to-super-tele zoom distinguished by its bright f/2.8 maximum aperture at the wide end of the zoom, along with its sleek and portable design. A series of specialized elements are used to maintain high sharpness and clarity throughout the zoom range. Benefitting the optical design is an RXD stepping motor, which enables quick, near-silent autofocus performance to suit stills and video, along with full-time manual focus override and a minimum focusing distance of 7.5". Suiting this lens's use in harsh climates, it also sports a moisture-resistant construction along with a fluorine-coated front element to protect against fingerprints and smudging. All-in-one zoom is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it will provide a 42-300mm equivalent focal length range. Bright f/2.8-5.6 maximum aperture range suits working in available lighting conditions, especially when working at the wide-angle end of the expansive zoom range. A series of specialized elements control a variety of aberrations in order to achieve high sharpness and clarity. RXD (Rapid eXtra-silent stepping Drive) autofocus motor delivers impressively quiet, quick, and smooth focusing performance to suit both stills and video applications. This focusing system also offers a minimum focusing distance of just 7.5" and a 1:3.1 maximum magnification for working with close-up subjects. Full-time manual focus override is also possible, and it is compatible with Sony's Direct Manual Focus function or fine-tuned manual control. A moisture-resistant construction benefits this lens' use in inclement conditions, and a fluorine coating has also been applied to the front lens element to protect against dust, dirt, and smearing. Rounded seven-blade diaphragm contributes to a pleasing bokeh quality. Zoom Lock switch keeps the lens in its retracted position when not in use. Thank you for watching.
