BH #TA1120S • MFR #AFB060S-700
Tamron 11-20mm f/2.8 Di III-A RXD Lens for Sony E
Key Features
  • Sony E-Mount / APS-C Format
  • 17-30mm (35mm Equivalent)
  • Aperture Range: f/2.8 to f/16
  • 1x XLD, 2x GM Asph., and 2x LD Elements
The dynamic 11-20mm F/2.8 Di III-A2 RXD Lens from Tamron is a fast-aperture ultra wide-angle zoom lens for Sony E-mount APS-C mirrorless cameras. It features the world's first f/2.8 maximum aperture for Sony E-mount APS-C mirrorless in this category and has a compact and lightweight design. This ultra-wide lens is particularly suitable for landscape, astrophotography, and architectural shooting. Its bright f/2.8 constant maximum aperture complements this range and affords increased control over depth of field along with enhanced low-light performance. The optical design incorporates one XLD element, two LD elements, and two glass-molded aspherical elements to produce a highly corrected image with reduced chromatic aberrations and color fringing for improved clarity and color accuracy. Individual elements also feature Tamron's BBAR coating, which suppresses flare and ghosting for greater contrast when working in backlit and harsh lighting conditions. A responsive RXD stepping drive motor enables quick, near silent autofocus performance to suit stills and video. The minimum object distance is just 5.9" at the widest end of the zoom range, unlocking powerful wide-angle macro shooting capability with a unique perspective that makes near objects look larger, and distant objects smaller. Additionally, the f/2.8 maximum aperture produces a shallower depth-of-field that creates soft bokeh background details. Moisture-resistant construction protect the lens under inclement conditions, and a fluorine coating on the front lens element protects against dust, dirt, and smearing.

Versatile ultra wide-angle zoom for Sony E-mount APS-C-format mirrorless cameras with a 35mm equivalent focal length range of 17-30mm.
Bright, constant f/2.8 maximum aperture affords consistent brightness throughout the zoom range and offers improved control over depth of field.
XLD (eXtra Low Dispersion), LD (Low Dispersion), and GM (Glass-Molded Aspherical) elements greatly reduce color fringing, chromatic aberrations, and image distortion throughout the zoom range for improved clarity and color accuracy.
BBAR-G2 (Broad-Band Anti-Reflection) Coating has been applied to lens elements to suppress internal reflections, flare, and ghosting to achieve greater contrast and color fidelity.
RXD (Rapid eXtra-silent stepping Drive) autofocus motor delivers impressively quiet, quick, and smooth focusing performance to suit both still and video applications. Compatible with Sony's Direct Manual Focus function and Eye AF on enabled cameras, and full-time manual focus override is available.
The minimum focusing distance of 5.9" at 11mm makes it possible to explore dynamic wide-angle macro imaging, making close objects appear larger and distant objects smaller. Additionally, using the f/2.8 maximum aperture produces a shallow depth of field with soft bokeh background details.
Designed and built with moisture-resistant construction for use in inclement conditions, plus a fluorine coating on the front lens element to protect against dust, dirt, and smearing.
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.

This is a sharp light weight lens that delivers clear images all the way to the corners of the image. I am impressed how close it can focus.

Great for scenery to Macro, sharpness equal to Sigma 16mmF1.4 but with added zoom reach. No need for lens changes, and is perfect match for Sony A-6600. DLW

I bought this lens for my Sony a6500 to create a fitness training video in a home living room that was too small for me to back up far enough to capture the full scene with my Tamron 28-75mm lens. The image quality is excellent, and the focus is fast, quiet, and spot on. I enjoy it so much, that I even began using my camera for zoom calls.

Fast wide angle zoom lens workaround for FF video

By Clarke
Rated 5 out of 5
Date: 2022-06-08

TL;DR - For shooting video on FF sensor... -Bought for real estate content -Best image: Set clear image zoom to 1.2x (but will disable Face/Eye AF) -If you need Face/Eye AF: Don't go below 14mm -For an APSC-C lens, it resolves best shooting in 4K (1080p is fine though on A7IV) -Requires reducing of vignette in post *DISCLAIMER* I'm knowingly/intentionally using this lens for video only on a full frame sensor which it is not designed for, and therefore I have several caveats for using this lens as mentioned above. But I gave it 5-stars because despite them because this lens gets the job done while checking so many boxes no other lens currently does and also I imagine on a APS-C camera this lens is absolutely stellar. WOULD NOT RECOMMEND IF YOUR LOOKING TO USE FOR PHOTOGRAPHY ON FULL FRAME DUE TO HEAVY VIGNETTING WHEN SHOOTING 3:2. I have a client that I consistently shoot architectural/real estate video content for and I needed to add a lens to my kit that could cover tight environments that my Sigma 24-70mm couldn't. I wanted a wide angle zoom that checked the following boxes 1. ultra wide option - 2 & 3. AF and lightweight for use on a DJI RS 2 - 4. Low aperture for low light environments - 5. Could take front filters so I can use VND - 6. Affordable. After looking at all the full frame options, it appeared I wouldn't be able to get exactly what I was looking for. My best bet was going with the Sony FE 12-24mm f/4 G Lens - but the front glass design doesn't allow for filters, the lens is f/4, and with tax is over $1,800 (which I could have accepted if not for the first two features) - so I decided to do more research. After watching Caleb Pike's 10 Sony Camera Hacks for Filmmakers! video and saw him use the APS-C designed Sony 10-18mm f/4 on the a7s III, I looked through all the wide angle lens options for APS-C on B&H and found this lens. The TL;DR above summarizes most of my observations about the lens, and I would just add that the AF works but I need to do more testing to determine exactly how well (obviously with ultra wide focal lengths, setting to manual focus covers a lot situations since it's already achieving deep focus). Since it's designed for APS-C, it doesn't resolves as well as FF glass, but shooting in 4K and then pixel peeping in post, it is acceptable for my purposes. If you're interested in this lens for the reasons I was, I'd recommend testing it for yourself. At the end of the day, for me this is speciality lens for shooting ultra wide video on a gimbal. And to that, it allows me to work incredibly fast on set, and the trade off is a little more work in post. *Please note my uploaded images are from H.264 compressed video*

Impressive Ultra-Wide lens. I love it

Initially I purchased the 17-70mm but I didn't like it as much for the type of shots I was trying to get so I returned it, got a store credit [painless process] then got this beast right here. If you are into landscape, travel, architecture stuff, this is your lens. You won't regret buying it. The sharpness is outstanding.

outside of it being a F/2.8, would it be worth buying this over the "Sony 10 - 18 F4" Lenses?
Asked by: Ryan
Tamron 11-20mm f/2.8 Di III-A RXD Lens for Sony E has a few advantages over the Sony E 10-18mm f/4 OSS Lens as the Tamron has a minimum focusing distance of 5.9" compared to 9.8" for the Sony lens. The Tamron is theoretically better built and has XLD (eXtra Low Dispersion), LD (Low Dispersion), and GM (Glass-Molded Aspherical) elements. However, the Sony has Optical SteadyShot Image Stabilization which is missing in the Tamron lens.

When manually focusing with the Tamron 11-20mm f/2.8 Di III-A RXD Lens for Sony E the focus position remains the same even when the camera is turned off. However, the focusing ring on the lens may still rotate when powered off, despite it not changing the focusing distance.
