Canon 70 200 Zoom Ring Loose

By | 13/11/2022

The Canon RF lxx-200mm F4 50 IS USM ($1,799) is, at its heart, a more affordable version of the RF 70-200mm F2.8 Fifty IS USM, a peak-end lens that sells for $two,700. Information technology’south just as well fabricated, and takes upwardly less room in your camera handbag thanks to a retractable design. It doesn’t get together as much light, so you’ll still want to pay for an F2.8 lens if you piece of work in dim low-cal or cover events. For the residue of us, the RF 70-200mm F4 L IS USM is a fantastic performer that pairs perfectly with pro and enthusiast Canon R cameras, and an Editors’ Choice honor winner.

Telescoping Barrel

Similar the RF seventy-200mm F2.8, the F4 edition features a retractable design. It’due south in contrast to seventy-200mm lenses for SLRs and other mirrorless systems, which near exclusively employ internal zoom. Information technology makes the lens equally minor as a typical 24-70mm when retracted, nigh iv.7 by iii.3 inches (HD).

The F4 lens is a little smaller all around than the RF 70-200mm F2.8, and lighter—one.v pounds versus 2.six pounds. The lighter build means you don’t need a tripod collar either, further reducing bulk. Bother inner and outer lens barrels use polycarbonate materials.

A reversible lens hood is included, along with a drawstring pouch. The front chemical element supports 77mm filters and has the expected anti-reflective and anti-smudge fluorine protection. The lens itself is protected from dust and splashes, just similar others in Canon’south Fifty series. Its light gray finish is a authentication of the L series.

Handling and Controls

Information technology’southward easy enough to cite the retractable pattern every bit a benefit when information technology comes to finding place in a camera bag, only there is a compromise in handling. The zoom action requires a bit more torque than lenses with internal zoom, so you’ll demand to get a skilful grip on the barrel to set up it; you won’t relish the fingertip zoom adjustment that internal zooms let.

The telescoping action is nothing new to camera systems, it’s something that y’all meet in nearly every zoom that goes longer than 200mm. If you must accept internal zoom, you can still look to a Canon SLR lens and the EF EOS R adapter.The EF seventy-200mm F4 and Sigma lxx-200mm F2.8 DG HSM Sports are priced similarly and zoom internally, merely are heavier and have upward more room in your photographic camera handbag.

In addition to the zoom ring, the lens includes detached manual focus and command rings. The command ring is located at the front. It turns with detent clicks and can be used to suit well-nigh two dozen functions—I discover it virtually useful for EV adjustment. Videographers may prefer silent control—it’s available as an option, but yous need to pay a modest fee, $79, and send the lens in for service to go it.

The focus ring is rubberized, merely similar the zoom control, and turns with a little bit of resistance. Information technology’s nigh as pleasing to use as mechanical transmission focus systems, but the focus throw is a little short for my liking. You can notwithstanding focus with precision, only information technology takes a bit of care.

Autofocus is nearly instant and absolutely quiet. There is a bit of animate—the result where the bending of view blooms and shrinks along with changes to the focus distance. It’s not a business concern for still imaging, simply can distract from video, specially if you’re recording a shot that racks focus from one discipline to another.

Focus is available to just nigh two feet (0.6m) throughout the zoom range. It’s proficient plenty for one:3.five macro magnification at 200mm, shut to what we consider the macro range for a zoom.

Optical stabilization is included. It works in conjunction with cameras that include IBIS, like the EOS R5 that I paired with the lens for testing, and is a big benefit if you use a model without a stabilized sensor, to appointment simply the EOS R and EOS RP.

With the R5, I netted handheld exposures with no blur with 1-second exposures without likewise much effort, correct in line with the 7.5-terminate CIPA rating. I didn’t have the opportunity to test on a torso without IBIS, but Canon promises about five stops of correction there—withal adept plenty for ane/half dozen-second exposures at 200mm.

Stabilization, focus, and other settings are configurable. The lens has a control panel on its side with focus limiter, AF/MF toggle, and stabilization controls. You tin turn stabilization on and off with ane switch and change the way it works with another. Way one is useful for most situations, Mode 2 is used when panning along with moving subjects, and Fashion 3 is for following subjects moving in unpredictable directions.

In the Lab

I paired the RF 70-200mm F4 with the 45MP EOS R5 and software from Imatest to check its resolution.

EOS R5, 191mm, f/4, one/200-second, ISO 100 (Jim Fisher)

At 70mm f/4, the pair nets resolution that’southward considered splendid for the R5 (4,000 lines). Edges are a picayune softer, but still proficient for a 45MP photographic camera. The overall resolution ticks upwardly at f/five.6 and f/8, where we see the clearest item (4,400 lines). You can stop downwards all the way through f/32, but you should avoid going past f/16—optical diffraction cuts into detail at the narrowest f-stops.

Encounter How We Test Cameras and Lenses

Resolution holds steady at 135mm, and ticks upwardly a bit at 200mm. This is a lens that’due south perfectly suited for the highest resolution Catechism sold today, and will deliver splendid results on the 20MP EOS R6 and 26MP EOS RP.

In that location’south some distortion in Raw images, simply in-photographic camera corrections remove information technology from JPGs. It’due south not overwhelming, with some butt distortion at 70mm and pincushion at 135mm and 200mm. Adobe hasn’t however added a correction contour for the lens, though information technology’due south all but certain to come up in the next Lightroom update.

Vignette correction is besides included in-photographic camera, but it’south barely needed for this lens. In that location’due south very little fall off in illumination through most of the zoom range. Corners are noticeably dimmed at 200mm f/four, but that’s it. It’s piece of cake enough to correct manually while we wait for a correction profile.

Fifty-fifty though this isn’t an f/two.8 lens, information technology still blurs backgrounds with ease. Defocused highlights take on the typical cat’s eye shape toward the edges of the frame when shooting at the maximum aperture, just are round through nearly of the frame. Narrowing the aperture to f/5.6 nets rounded highlights beyond the board.

The Meaty Telezoom to Get

Photographers invested in the Canon EOS R system now have two excellent midrange telezooms available. Pros covering events and weddings, or specializing in portraiture, tin can justify spending $2,700 on the RF lxx-200mm F2.8 Fifty IS USM. But aside from the f-end, yous don’t miss a thing by spending less on the F4 edition.

The RF 70-200mm F4 L IS USM is just as stunning a performer equally the F2.viii. It captures images with exquisite item, fifty-fifty on Canon’s most demanding photographic camera, and blurs background with ease. The lite build is perfect for travel, and outdoor photographers will appreciate its almost macro focus and weather protection.

The telescoping design may still be divisive, peculiarly if yous take years of experience using a lxx-200mm with an internal zoom. Canon’s EF lxx-200mm F4 remains a solid alternative if you lot prefer, but you’ll demand a lens adapter. I don’t mind the telescoping activeness, though, and at that place are plenty of 100-400mm zooms that work the aforementioned style.

We’re naming the RF 70-200mm F4 L IS USM an Editors’ Choice winner. Photographers using the Canon R arrangement should take a close look—aside from the f-end, in that location are no compromises versus the F2.viii edition. Wedding pros tin can certainly justify spending more than, only nosotros think most shutterbugs volition get only as much out of this lens, for a good bargain less than the toll of the F2.eight.

The Bottom Line

The Canon RF 70-200mm F4 50 IS USM is a meaty zoom with quick focus and exquisite optics. Pros may still want a F2.8 zoom, just this is more than enough lens for nearly photographers.
