I'll start by saying, "in-depth" is relative in this case. The Canon RF 100-500mm F4.5-7.1 L IS USM Lens and Canon EF 100-400mm f/4.5-5.6L IS II USM Lens are two of the best telephoto zoom lenses ever made. As long as the lens will mount on your camera (the RF lens requires a Canon EOS R-series camera), there is no bad choice to be made here. Overall, these lenses are similar in so many regards that it is a stretch to create an "in-depth" comparison.

Let's start by looking at the name. Obvious is that the RF lens has a considerably longer focal length range. The 400mm vs. 500mm difference is illustrated in the RF 100-500mm Lens review. The 500mm focal length is very noticeably longer than the 400mm focal length, and I can think of no reason to not prefer the longer range. That is, no reason as long as the maximum aperture remains similar at 400mm.

We know from the name that the RF 100-500's max aperture is narrower at the 500mm end, and the unusually narrow to-f/7.1 spec gives us pause. The Dual Pixel CMOS AF system in Canon's R-series cameras autofocus lenses with narrow apertures very adequately, making very narrow openings quite usable, but we still want to know if the aperture opening size was being sacrificed at the 400mm focal length to keep this lens compact and light.

What is the Canon RF 100-500mm F4.5-7.1 L IS USM Lens's maximum aperture opening at 400mm? The early answers were:

Answer 1: When the camera is set to 1/3-stop increments, the maximum 400mm aperture reported to the camera is rounded to f/6.3.

Answer 2: When the camera is set to 1/2-stop increments, the maximum 400mm aperture reported to the camera is rounded to f/5.6.

While the max aperture does not change in these modes, the rounding of the actual opening size does, and the true aperture is likely between these two numbers, holds for only a short range of focal lengths, and the 1/3-stop difference in noise made visible by an offsetting 1/3-stop ISO change will matter to few. For the RF lens, Adobe software says that 400mm is f/6.2 (and that 500mm is 7.0).

Here is a comparative look at the max aperture step-down by focal length for these two lenses:

Modelf/4.5f/5.0f/5.6f/6.3f/7.1
Canon EF 100-400mm L IS II100-134mm135-311mm312-400mm  
Canon RF 100-500mm L IS100-150mm151-253mm254-362mm363-471mm472-500mm

While the RF 100-500 holds f/4.5 modestly deeper into the focal length range, the EF 100-400 L II holds a modest advantage at the longer focal lengths. Still, the differences are minor.

Back to the focal length range available: both lenses accept extenders, enabling the native focal length range to be significantly lengthened. Noteworthy is that the RF lens will not zoom wider than the marked 300mm native focal length while an extender is mounted. Extenders are primarily used for obtaining a focal length not native to the lens, meaning the 300mm wide end limitation is not important. The RF 100-500 better avoids the need for extender use, but being able to zoom out is sometimes helpful when an extender is mounted, such as when finding a subject in the viewfinder, and being able to fully zoom out makes the lens significantly more compact. Very noticeable is that the 100-500 range can be extended substantially longer than the 100-400mm range, up to 1000mm vs. 800mm. The max aperture of 500mm with extenders becomes rather narrow, though as we just looked at, the difference at the equalized 400mm focal length is minor.

Let's look at the image quality comparison next. The RF lens has less lateral CA in the periphery at 100mm and might be slightly sharper at this focal length at f/4.5. That is the only even somewhat noteworthy difference I see in the shared focal length range. Comparing the image quality from these two lenses at f/8 will hurt your eyes.

Of high interest to many of us is the RF 100-500mm lens at 500mm vs. EF 100-400mm with 1.4x at 560mm comparison. In this comparison, the RF lens is sharper, especially in the center of the frame. The EF lens leapfrogs the RF lens focal length, but the RF lens has a wider aperture. Mount 1.4x extenders behind both lenses and the EF lens appears to hold a very slight edge. Keep in mind that the comparison is now 700mm f/10 vs. 560mm f/8, not especially apples-to-apples. I'm not a fan of the 2x extender behind either of these lenses, but they perform very similarly in the 1000mm vs. 800mm comparison.

The RF lens shows fewer flare effects in our testing (having one less lens element is likely advantageous) and has modestly more peripheral shading with a wide-open aperture at 100 and 200mm.

Looking at specs and measurements, the Canon RF 100-500mm F4.5-7.1 L IS USM Lens vs. Canon EF 100-400mm f/4.5-5.6L IS II USM Lens comparison shows the RF lens slightly longer and noticeably lighter.

As illustrated in the image included with this article, today's length equation is:

EOS R5 + Canon RF 100-500mm L IS Lens = Canon EOS 5Ds R + Canon EF 100-400mm L IS II Lens

The EOS R5's extended viewfinder rises modestly higher than the 5Ds R's viewfinder, but this increase is advantageous in use.

Let's change the RF vs. EF equation to weights:

In ounces: (26.0 + 48.2) - (32.8 + 56.1) = 74.2 - 88.9 = -14.7 oz

In grams: (738 + 1,365) - (930 + 1,590) = 2,103 - 2,520 = -417g

Overall, the RF lens and R camera combination gives us an additional 100mm of focal length range in a similar-sized package that weighs nearly a pound (over .4 kg) less. Primarily, this line summarizes the significant differences between these lenses.

The RF lens has a control ring, providing additional functionality. The EF lens requires a Canon Mount Adapter EF-EOS R to mount on an R-series camera, and an adapter with a control ring is available to equalize this difference. With the RF lens control ring positioned where the EF lens's switches are located, the RF lens switches required a move and are now located between the zoom torque adjustment ring and the focus ring. The RF lens focus ring and zoom rings are modestly smaller in length, and the focus distance window is omitted on RF lenses.

The EF lens tripod foot is removable (and has a lower profile), while the RF lens's entire tripod ring is removable. I prefer the RF design for stability.

The RF lens has a slightly higher maximum magnification (0.33x vs. 0.31x), but both lenses have a great capability in this regard. The RF lens's image stabilization system is rated at 5-stops vs. the EF lens's 4-stop rating.

The RF lens paint color is whiter (the new white) than the EF lens's color, and RF lens hood is primarily white, while the EF lens hood is black. The RF lens zoom torque adjustment ring is now fully ribbed, and the RF lens barrel holds a more constant diameter over its length. Both lenses are well-built and fast-focusing.

The RF lens costs more, but neither lens is inexpensive. If paying this much, the difference is relatively small. Factor in the cost for an adapter for the EF lens to mount on an R-series camera, and the net difference is even less.

I recently shared an adapter modification that permitted Canon RF extenders to be used behind all (most?) Canon EF lenses — and Canon EF lens and EF extender combinations. The next idea was to push the overall focal length using double extenders.

The image shared with this article shows the following setup, from right to left, then down:

Doing the math:

600mm x 2 x 2 = 2400mm

That is an impressive focal length.

I originally inserted a Canon EF 12mm Extension Tube II behind the EF 2x, enabling a Canon EF 1.4x III Extender to be added to the optical path. That addition would have resulted in an awesome 3360mm lens, but the extension tube broke the electronic connection required for this lens to focus, even manually. The resulting combination was useless, aside from looking amazing.

Back to the 2400mm setup. The second equation this combination creates is considerably less exciting:

F/4 - 2 stops - 2 stops = f/16

The first equation results in an incredible number that is offset to some extent by the result of the second equation. Remarkable is that the EOS R5 focuses this combination very quickly in good light, avoiding focus hunting if the subject is not too significantly out of focus. Keeping a 2400mm lens still enough for sharp images remains a challenge, and with two 2x extenders in the optical path, this rig is not too sharp. Here is a 100% crop processed from a RAW image in Canon Digital Photo Professional (DPP) using the Standard Picture Style with Sharpness = "1" (0-10 scale).

Sharpness at 2400mm

On the fun side of the equation, the awkwardly-shaped 92.7% waning moon nearly fills the 2400mm frame. At this magnification, the thermal irregularities in Earth's atmosphere are apparent even in the viewfinder. And, the moon has to be tracked continuously to keep it centered in the frame (after the challenge of finding it in the frame has been met).

Disclaimer: Use of this information is at your own risk, and "All" is more likelihood than fact as I have only tested a small percentage of the available lenses.

In a recent article, I answered the question, "Can Canon RF Extenders be used with the EF-EOS R Mount Adapter?"

That answer was "No."

The Canon Mount Adapter EF-EOS R (basic and control ring versions) has no optics. It simply moves the EF mount forward, offsetting the short back focus design of the RF mount, and provides the communication connections required for the lens to function as native. Hoped for was that the open space in the Canon Mount Adapter EF-EOS R would permit an RF extender to fit into the back of it, ideally making all EF and EF-S lenses extender compatible. Unfortunately, the Canon RF extenders do not fit into the Canon mount adapter.

However, the baffle physically preventing this installation appears to be plastic, and plastic is easily modifiable. I couldn't spare a Canon adapter for this mod (they are unavailable as I write this), but after studying the Vello Auto Lens Adapter for Canon EF/EF-S Lens to Canon RF-Mount Camera product images, I suspected the relatively large inside diameter of this adapter could more easily be modified to permit fitting of the Canon RF 1.4x Extender and Canon RF 2x Extender. B&H was up for this challenge and sent me an adapter to potentially destroy.

Vello EF-to-RF Adapter

Not surprising was that the RF extenders do not fit into the back of the Vello adapter out of the box. Thus, some modification was necessary. Basically, the plastic on the raised interior section housing the communication pins needed to be removed down almost to the wires. To protect the adapter and to keep it clean, I gaffer taped everything I didn't want to remove — most of the adapter. Next, a rotary tool (I substituted a drill) with a small abrasive sanding cylinder was used to remove the plastic. A rounded file could also be used.

Vello EF-to-RF Adapter Modified

After removal of enough plastic for the extenders to fit (this took two tries for my first attempt), the adapter was cleaned and mounted. Being able to mount the extender behind the adapter was the first test to pass. Having the extender function properly in conjunction with EF lenses was the bigger question in my mind. Fortunately, the modified adapter passed that test also.

How good is the image quality? We haven't lab tested the modified adapter and more testing needs to be done, but this combo seems to deliver very good quality images with a high quality lens in front of it. The Canon EF 24-70mm f/2.8L II USM Lens seemed to perform especially well with the image periphery perhaps becoming slightly softer. Here is a 100% crop from a Canon EOS R5 image processed from RAW in Canon Digital Photo Professional (DPP) using the Standard Picture Style with sharpness set to "1" (0-10 scale).

Canon RF 1.4x Extender with Vello EF-to-RF Adapter Sample Picture

Note that this setup does not report the reduced aperture and increased focal length to the camera, but the camera continues to work normally.

The adapter modification was not hard to make. Buy a Vello Auto Lens Adapter for Canon EF/EF-S Lens to Canon RF-Mount Camera and follow the steps shared above. I suspect that the greater good of this project was testing the concept. Watch for commercially available adapters designed to fit on a Canon RF extender in your favorite store soon.

We have not tested the Canon EF 800mm f/5.6L IS USM Lens on the Canon EOS 5Ds R, so some discernment is required in the Canon RF 800mm F11 IS STM Lens vs. the Canon EF 800mm f/5.6L IS USM Lens comparison.

I was recently asked which EF lenses should be replaced first in the DSLR to MILC (Mirrorless Interchangeable Lens Camera) migration. Fortunately, Canon has made the Mount Adapter EF-EOS R available to significantly ease that transition. With this adapter, EF lenses continue to perform at least as well on an RF mount as they do on an EF mount. Still, many of us will be upgrading our kits to RF lens models.

Here is a list of the available (or announced) RF lenses in priority* order.

  1. Canon RF 24-70mm F2.8 L IS USM Lens
  2. Canon RF 70-200mm F2.8 L IS USM Lens
  3. Canon RF 15-35mm F2.8 L IS USM Lens
  4. Canon RF 100-500mm F4.5-7.1 L IS USM Lens
  5. Canon RF 24-105mm f/4L IS USM Lens
  6. Canon RF 50mm f/1.2 L USM Lens
  7. Canon RF 85mm F1.2 L USM Lens
  8. Canon RF 85mm F1.2 L USM DS Lens
  9. Canon RF 85mm F2 Macro IS STM Lens
  10. Canon RF 35mm f/1.8mm f/1.8 IS STM Macro Lens
  11. Canon RF 600mm F11 IS STM Lens
  12. Canon RF 800mm F11 IS STM Lens
  13. Canon RF 28-70mm f/2L USM Lens
  14. Canon RF 24-240mm F4-6.3 IS USM Lens
  15. Canon RF 24-105mm F4-7.1 IS STM Lens
  16. Canon RF 1.4x Extender
  17. Canon RF 2x Extender

* Disclaimer: photographers have greatly varying needs, and therefore, the priority number for each of us may vary greatly, and my numbers may have little meaning for you.

The easy answer to the "Which RF lenses should I upgrade to first?" question is "Replace your most-used lens." All of the RF lenses have advantages over their EF counterparts, and replacing the most-used lens makes a lot of sense, providing the most value.

Also making sense is upgrading to an RF lens that has a desired capability, such as the image stabilization feature in the RF 24-70, much better image quality such as found in the RF 50 L or RF 85 L, or a super-telephoto length at an affordable price.

Why The Above Order?

The trinity of professional-grade f/2.8 L lenses are listed first, and they are listed in order of use frequency for many photographers. These are the lenses this site's audience considers most important overall.

I dropped the RF 100-500 into the 4th slot on this list. This focal length range is extremely useful, includes very long focal lengths, and has professional-grade build and optics without reaching an extreme price level.

For some, the RF 24-105 f/4 L could have a top position on this list. This lens is great for travel and has great general purpose utility. The professional-grade 24-105 L is less expensive and lighter than the RF 24-70 f/2.8 L.

Bring in the primes. The RF 50 L is the 50mm full-frame lens that many of us have long awaited. It is the first Canon 50mm lens I've personally purchased in (probably) over a decade. Both RF 85 f/1.2 models are phenomenal portrait lenses, and people are the most important photo subject. With stock photos unavailable for most people, portrait photography remains a revenue-generating pursuit. The RF 85 f/2 IS promises solid performance at a lower price, and this lens's close-focusing capabilities will be very welcomed in a kit.

The RF 35 is small, light, bright, close-focusing, inexpensive, and fun. Just get one.

An f/11 fixed aperture lens? Sounds like a crazy idea to many of us. However, getting these extreme focal lengths into the size, weight, and price point Canon achieved is remarkable. The image quality is not bad, especially from the lower resolution imaging sensors.

Having an f/2 aperture available over an entire general-purpose focal length range is awesome. The RF 28-70 is large, heavy, and expensive, but for the niche that needs this lens' advantages (think wedding and event photographers), this lens is priceless.

There are times when only a single lens can be chosen for multi-purpose needs. The RF 24-240mm lens's 10x zoom range covers those needs much of the time.

When small, light, and inexpensive are critical lens attributes, the RF 24-105mm F4-7.1 raises its hand to fill the need.

I listed the RF extenders last. At this time, only the RF 100-500, RF 600, and RF 800 are compatible with the RF extenders. The cost of the extenders is approaching the cost of these two low-priced prime lenses that already have very long focal lengths, and the narrow max apertures of these lenses reduces the benefits an extender can provide. Using the 1.4x on the not-yet-available RF 100-500 is going to make a lot of sense, but I'm less sure about the 2x. I expect the extenders to have significantly greater value when high-end RF telephoto prime L lenses become available.

I plan to migrate all of my Canon lenses from EF to RF where similar models exist (except for those required for testing purposes). If your budget enables upgrading, I recommend doing so.

What is your RF lens plan?

OK, maybe not "finished" as I will likely continue to update these reviews for a long time, but these reviews are now extensive enough to be called finished for the moment. As the R5 and R6 are similar in many regards, selecting the review of your preferred model and reading the comparison will likely give you the information you need. Get a coffee and start reading:

Should I Get the Canon EOS R5, EOS R6, or EOS R? An Extensive Comparison

I have not been this excited about a camera in a long time — two R5 bodies are now part of my kit. It will now be hard to go back to a DSLR.

Image quality test results have been added to the Canon RF 600mm F11 IS STM Lens page.

This is an interesting lens from numerous perspectives, but focal length per dollar (euro, pound, etc.) is one, and focal length per lb (kg) is another. Here is a comparison with Canon's other 600mm lens, both set to their widest apertures:

At f/11, the RF 600 is already being impacted by the softening effects of diffraction. Another interesting comparison is between the same two lenses at f/11.

Image quality, vignetting, and distortion test results have been added to the Sigma 24-70mm f/2.8 DG DN Art Lens page.

This is a top-selling lens. Our review of the Sigma 24-70mm f/2.8 DG DN Art Lens was interrupted by the new Canon gear arrival, but the test results are very helpful in telling this lens's story.
