The Canon RF 70-200mm F4 L IS USM ($1,599) is, at its heart, a more affordable version of the RF 70-200mm F2.8 L IS USM, a top-end lens that sells for $2,700. It's just as well made, and takes up less room in your camera bag thanks to a retractable design. It doesn't gather as much light, so you'll still want to pay for an F2.8 lens if you work in dim light or cover events. For the rest 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 award winner.Telescoping Barrel Like the RF 70-200mm F2.8, the F4 edition features a retractable design. It's in contrast to 70-200mm lenses for SLRs and other mirrorless systems, which almost exclusively use internal zoom. It makes the lens as small as a typical 24-70mm when retracted, about 4.7 by 3.3 inches (HD). The F4 lens is a little smaller all around than the RF 70-200mm F2.8, and lighter—1.5 pounds versus 2.6 pounds. The lighter build means you d...

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

Light, compact telezoom; Excellent resolution; Dust, splash, and fluorine protection; Quick, quiet autofocus; Optical stabilization works with IBIS; On-lens controls

Gather less light than an F2.8 lens; Shows some focus breathing; Divisive telescoping design

Offering a similar level of performance to the much more expensive RF 70-200mm f/2.8L IS USM lens, the RF 70-200mm f/4L IS USM represents a wise choice for photographers who don’t need the one-stop advantage the f/2.8L lens provides as well as those looking for a more portable lens for hand-held...

The new EF 70-200mm F4L IS II USM represents a major update of Canon's venerable 70-200mm F4 lens, replacing the 12 year old Mark I version by introducing a number of significant improvements.

This is a fantastic lens! Possibly the best value in the Canon line. Quick accurate focus with beautiful results. It is f/4 so one has to understand limitations vs what a f/2.8 version may deliver, still I am able to achieve excellent images in challenging light with my 6D.

Fabulously sharp; Lightweight for a 70-200mm lens

Stabilization and AF doesn't outperform the equivalent Tamron lens

Use this lens all over the world. Moderate telephoto is very useful. Images sharp and tolerate editing well. It's much lighter than the f/2.8 and this factor means my wife will carry it as well as me. Buy the L lens. I have many L lenses and they are far superior to the standard USM.

This is a great lens if you want to spy on people or get shots from a distance. I don't spy on people but I just thought I'd point that out. This is a great lens though, but tbh, I am no expert. This was my first lens I ever bought so it's kind of special to me.

This is my 5th L lens and may very well become my favorite due to its versatility, weight, great IS and image quality. I wrestled with whether to get the f/2.8 lll, but, after reading the reviews, it seemed that the only advantage was the 1-stop aperture availability, which is a valid consideration.

Very nice & great value for money..I am using this lens since one year
