Overview

RF 16mm F2.8 STM Lens

Compact, versatile, speedy and affordable, the new RF16mm F2.8 STM lens is a terrific complement to any EOS R series digital camera. Offering an ultra-wide angle of view and a bright f/2.8 aperture, it's an excellent choice whether taking interior photos in tight spaces, seeking out the perfect landscape, or as the perfect webcam lens when used in combination with an EOS camera and EOS Webcam Utility on a video call. With a 16mm F2.8 lens, you can experiment with enhancing perspectives, capturing starscapes, or with the close focusing distance of 5.11 inches, get up close to your subject while still keeping the background more visible. Video users will find this ultra-wide lens a natural for vlogging, especially with its supremely light weight.

With its remarkable combination of optical excellence and refined performance, all in a small package that's easy to bring most anywhere, the RF16mm F2.8 STM is a stellar companion to any EOS R series digital camera.

Features:

Canon’s first ultra wide-angle, fixed focal length RF lens

A fixed ultra-wide angle lens changes how you see your image before you even press the shutter button. Your enhanced perspective and expansive views create a unique and engaging look of each photo. Whether you are capturing an awe-inspiring starscape, portraits with fun and unique distortion or simply a group selfie while on vacation, the combination of the open f/2.8 lens and ultra wide-angle 16mm field of view makes this a light weight and versatile lens to pack anywhere you go.

High image quality and bright, fixed f/2.8 maximum aperture

A bright f/2.8 lens combined with the full-frame sensor of each EOS R series digital camera allows for fast shutter speeds in low light with less noise and the ability to beautifully blur the background in close-up shooting or video recording.

A stepping motor (gear-type STM) that provides smooth and quiet continuous AF during video recording

Using a stepping motor in the RF16mm F2.8 STM lens aids in natural focus while following a subject using Servo AF in still photography, or clean transitions when repositioning to another subject with Movie Servo AF in video applications. Canon's STM focus motors are especially renowned for their smoothness in focus changes during live video recording, as well as brisk AF during still-image shooting.

Supremely lightweight and compact, for an ultra-wide lens for full-frame cameras

The compact size and light weight of the lens makes it an ideal companion on long hikes and excursions. It is also handy for a day out in the city and when you want to be creative with multiple prime lenses.

Minimum focusing distance of 5.11 inches and maximum magnification of 0.26x

Getting close to your subject with the RF16mm F2.8 STM lens means purposefully distorting your subject, creating an enjoyable new look while also keeping more of the background in frame for visual interest.

Control/Focusing Ring can directly adjust numerous settings

The RF16mm F2.8 STM lens incorporates a control/focus ring on the lens barrel. As a Control Ring, it can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the end of the lens, the control/focus ring has a tactile, easily distinguished surface and provides tangible feedback for confident use while looking through the viewfinder.

Circular 7-blade aperture helps deliver beautiful, soft backgrounds

You'll have no problem when shooting close-up images in getting that creative, fun and pleasantly smooth out-of-focus background blur we all love with the circular 7-blade aperture. Subjects will stand out, and the background provides a beautiful backdrop that's visually appealing in itself.

Just what I needed
Size: 4 Panel-136"W, Color: Black
I have a one bedroom apt and my son stays with me half the time. He has an air mattress in the living room until I can afford a 2 bedroom. But he’s in his early teens and needs privacy. I bought this after looking online at may of these. I’m so glad I went with this one. It covers his air mattress 3/4 of the way around and now he has his own little nook. I also gave him some led lamps and he might it like his own little nightclub. He LOVES it. And now he’s excited to be in his space. The quality is so good and there’s no see through, no gaps, it’s perfect.

Instructions could be clearer, but assembles well and is sturdy
Size: 3 Panel-102"W, Color: Black
The only reason for the lack of a star is the iffy instructions. There are a few different washers and the instructions could make the difference a LOT easier to understand and thereby reduce the need to re-do things. Other than that, the panels were easy to assemble and the parts fit well together. I was able to disassemble the screens and store them for a future use, which is nice. One caution - the feet that make the panels stand up will likely be a trip hazard, so be sure to plan the location for this device carefully.

Awesome product!!!
Size: 3 Panel-102"W, Color: Beige, Size: 3 Panel-102"W, Color: Beige
This thing is really awesome. I actually bought 2 of them and made myself a nice little enclosure to keep out any peeping Toms while I’m trying to work on my summer tan. What I was looking for is FULL privacy and this DEFINITELY provides that. Fabric is completely opaque, you cannot see anything through it which is exactly what I needed. Another huge bonus is the strips of fabric to cover the spaces in between the panels, giving TRUE privacy. This is a really well-made product, great design, great structure, and pretty easy to put together overall. The only downside is that with strong gusts of wind, it wants to tip over so as you can see I secured the bottom feet with a couple bricks to make it stable and that did the trick. But to me that is a minor inconvenience given all its other great aspects. So many other privacy dividers were still see-through… totally defeating the purpose. But this one is absolutely full privacy and PERFECT for what I needed it for!!!

not accomodating
Size: 4 Panel-88"W, Color: Grey
The product is ok, it is only meant to look nice on one side, meaning the cover is only for one side to cover the cracks by the pole. I requested additional parts and they would not provide. Poor service. I can't get the parts anywhere else so now I have to take it apart and return the item.
