I find it useful for direct EV adjustments, but your mileage may vary. You can set the function of the third control ring that sits at the front of the barrel via the camera menu. It's a strong option for video, either with an EOS R mirrorless camera or Canon's RF-mount EOS C70 cinema camera. Focus breathing is well controlled and there's no apparent change in angle when setting focus. The RF 14-35mm supports both linear and nonlinear focus response the focus control direction is reversible, too.

Vloggers and snapshooters will be content to let the camera drive focus, but for more serious video work, manual focus is still preferable. This design touch is thoughtful and goes a long way to prevent you from tapping the manual focus ring that sits just in front of it.Īutofocus is quiet and quick, while manual focus behavior is pleasant.
It sports rubber ridges and is tapered, with its diameter at the front slightly larger than at the rear. The zoom ring is the largest of the three rings and sits closest to the lens mount. The RF 14-35mm includes three on-barrel control rings and a pair of toggle switches: one swaps focus modes and the other turns stabilization on or off. Aside from the hood, the lens ships with a pinch-style lens cap, a standard rear cap, and a soft drawstring pouch. The ultra-wide's petal-style lens hood has a push-button lock. The front element benefits from an anti-smudge fluorine coating and is flat enough to support 77mm threaded filters. Like other L lenses, it features dust and splash protection and is suitable for use outdoors even when the weather gets a little rough. The RF 14-35mm is part of Canon's L series, the designation for its highest class of lenses. We haven't reviewed the Tokina atx-i 17-35mm F4 ($599) for Canon SLRs, but it's one to consider if you're on a budget. Major third-party lens manufacturers haven't jumped on to support the system yet, so you're limited to Canon's lenses unless you reach for the EF-EOS R adapter. The RF 14-35mm F4 takes up less room in your bag than the other wide zoom for Canon's EOS R system the 15-35mm F2.8 measures 5.0 by 3.5 inches and weighs 1.9 pounds. The RF 14-35mm measures 3.9 by 3.3 inches (HD) and weighs just 1.2 pounds, not far off from the Nikkor Z 14-30mm F4 S for the Nikon Z system (3.4 by 3.5 inches and 1.1 pounds). Canon takes a page out of rival Nikon's playbook here and delivers an ultra-wide zoom that you'll want to take with you. Ultra-wide lenses are useful tools for capturing wide landscapes or exploring the tight spaces of the urban world, but they're not always the easiest to carry.
We still recommend the RF 15-35mm F2.8 L IS USM for more critical and technical work, but the RF 14-35mm is a better fit for those who want to pack light.

The 14-35 F4 has more optical compromises than you might expect from an L series lens, but you may forgive those flaws because of how compact it is. It's not a surprising design choice many of Canon's RF lenses prioritize portability. The Canon RF 14-35mm F4 L IS USM is an exceptionally lightweight zoom lens, especially when you realize it's made for full-frame sensor cameras and enables an ultra-wide angle of view.

With unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (Un), and ISO metric thread profiles, hex nut dimensions are described in both metric and imperial sizes. Hex nuts are also known as hexagon nuts or six-sided nuts. Both types of bolts can be used with hex nuts.
The hexagonal body allows for fast wrenching while still applying sufficient torque to the bolting joint. Its use, however, is not restricted to hex-headed bolts. Hex Nuts are hexagon nuts with six sides that are used to tighten bolts and screws. Heavy Hex Nuts are larger and thicker than standard (finished) hex nuts.The heavy hex pattern is typically used for large diameter and high strength bolts, and with certain high-strength grades of steel can be used with structural bolts in structural applications.Ī heavy hex nut is visibly different from a normal hex nut or finished hex nut in that it is bigger and stronger.
