It would be very difficult to beat the Olympus system when weight is a factor.

Full frame mirrorless cameras don't save very much weight...

7D Mark II... 2 lb. (with battery and memory card)
5D Mark IV... 1.76 lb. (body only)
Canon R5... 1.62 lb. (w/battery & memory)
Sony A7 III... 1.43 lb. (don't know if that incl. batt/memory)

So, at best, the camera change would save you about 1/2 lb. or 8 oz.

And full frame cameras need full frame lenses.

Canon has been doing some innovative things with their RF lenses. The new RF 600mm f/11 and 800mm f/11 are pretty amazing and even affordable (but also are f/11!). They're using diffractive optics to help keep them reasonably compact and lightweight.

Canon and Nikon 800mm f/5.6 lenses are around 10 lb. and $13,000 to $16,000, respectively. The RF 800mm f/11 is under 3 lb. and $900.

Canon, Nikon and Sony 600mm f/4 lenses weigh 6.7 lb., 8.4 lb. and 6.7 lb. respectively, and each costs upward of $12,000. The RF 600mm f/11 is just over 2 lb. and $700.

The Canon RF 70-200mm f/2.8 also lost a lot of weight and size (when retracted), by no longer being internal focusing.

Canon EF, Nikon F-mount and Sony 70-200mm f/2.8 each weigh about 3.15-3.25 lb. The RF 70-200mm f/2.8 is close to a pound lighter, at 2.35 lb.! They all cost between $2400 and $2600, except the Canon EF 70-200mm f/2.8 IS USM III, which is now selling for $1900.

Canon has a new RF 100-500mm f/4.5-7.1L IS USM lens coming soon that looks like a great choice for wildlife and - in spite of the add'l 100mm - at 3 lb. is over a half pound lighter than the EF 100-400mm "II". The RF 100-500mm isn't in stores yet, but is expected soon and will cost $2700.

Sony has an interesting 200-600mm f/5.6-6.3 OSS lens that also would be great for wildlife and costs under $2000. But compared to some of the above mirrorless lenses, is fairly hefty at over 4.5 lb. However, it's considerably lighter than 600mm f/4 and 400mm f/2.8 super telephotos.

Sony offers a 100-400mm f/4.5-5.6 OSS lens too... $2500 and at about 3 lb., the same weight as the Canon RF 100-500mm or less than a half pound lighter than the Canon EF 100-400mm II.

There's also a Sigma 100-400mm available in e-mount ($950), which is surprisingly light at 2.7 lb. (Sigma lenses typically are bigger & heavier than similar lenses from other makers). Apparently this lens is not yet available for Canon R-series mirrorless, but I imagine it eventually will be. (They offer a different 100-400mm for Canon EF mount DSLRs).

Unfortunately... wildlife photography = large, heavy, expensive lenses... especially with full frame cameras. Instead of full frame, you might consider downsizing to an APS-C mirrorless. Sony and Fuji are probably your best bets, as they have the most comprehensive systems. With one of their APS-C cameras, you could use a 200mm lens instead of 300mm on full frame... or a 300mm lens instead of a 500mm on full frame.... or a 400mm instead of a 600mm on FF. Of course, you could also use the APS-C Canon 7DII in similar manner, but the weight savings won't be as great.

One possible drawback with lighter and smaller APS-C mirrorless is that they don't balance very well with moderately large telephotos. If you plan to use 300mm and longer lenses on it, you might want to steer clear of the smallest APS-C mirrorless and possible make a point of getting one that can optionally be fitted with a battery grip, to better balance with big lenses when needed.

WOW!! You’ve really done your homework! Sounds like Canon is the clear winner for the OP. It’s not really a fair comparison for same size lens but way different f-stop i.e. (your words):

“Canon, Nikon and Sony 600mm f/4 lenses weigh 6.7 lb., 8.4 lb. and 6.7 lb. respectively, and each costs upward of $12,000. The RF 600mm f/11 is just over 2 lb. and $700.“

The cost and weight differences are significant, though and if the RF 600mm f/11 does the job, then I say, GO FOR IT.

Very informative post. I shoot Sony full frame and the Sigma 100-400 you mentioned MIGHT be a better option than Sony’s G-master 100-400 Lens. Cost difference is significant!

The new Canon R5 and R6 together with these new light f/11 lenses are a game changer.

f4 vs f11? I'm not sure I have enough toes to figure out how many stops that is. I definitely can figure out the difference between $12,000 and $700 though.

I just purchased this camera last week and shot with a Nikon D500 with a 150-500 and was getting tired of carrying the big lense for wildlife photos. This camera is amazing!! I just added a bunch to the photo gallery


I’ve considered this camera as a one-size-fits-all travel camera. I tried it out in the store and it seemed a little shaky at 600 mm. Of course, the salesman tried to talk me into the Sony 100-400 Lens!!!! What’s your take?

Great choice.


I agree that you made a good choice. When I switched from Nikon to Sony, I kept a few of my favorite Nikon lenses and bought a Sony to Nikon adapter. It works great and was a better financial decision than selling the Nikon lens and buying the equivalent Sony lens.

I just spent a few weeks with an R5 rental while waiting for mine to arrive. It's very comfortable to hold and fits in the same sleeve as my 80D. The feel and size is very similar and it's easy to carry in one hand. I bought the RF 24-240 lens and EF-RF adapter. Also rented the RF 800. The RF lenses work very well and are not heavy. All of my Canon EF, EF-S , Tamron and Sigma lenses worked great. The only lens I couldn't get to work was Rokinon 14mm. My recommendation is to try a rental and see how it works for you. If you use your existing glass you might save enough to offset the price of the camera. And you won't be trying to learn a new camera system.

I love to do wildlife and nature in general so I usually have to haul gear around. If i switch, I want another full frame camera so my thought was to move to mirrorless to save the weight. I could of course, get one of the new Canon bodies and use my current lenses, but I'm thinking that won't save me much weight. Or, i could go with the newer Sony a7 iii and some Sony lenses.

If I could get to a store that was open and could hold the Sony a7iii with at least a 100-400 lens, i might be able to actually have the answer to my dilemma.

Anyone else have a similar situation?

check out the newly announced sony a7C (it's a full frame compact camera) 24 meg mirrorless looks a lot smaller most likely lighter too.

So if the full frame size glass from sony isn't any lighter, you just answered my question. I have no reason to switch. Thank you!!


Something a mirrorless shooter mentioned is that because the sensor is more exposed in the mirrorless system, he found he was constantly having to clean the sensor, blow out the interior etc. That's a deal-breaker for me.

Until that nuisance factor is removed from them, I'm not tempted by them.

I too am getting older and and carrying heavy gear away from home is not much fun . I have a Nikon D500 and many DX and FX lenses. Recently I sold a lot of gear 2 DSLRs and several film bodies. With the money I plan to buy a NIKON Z50 mirrorless, 2 lens’s kit with FTZ adapter when Nikon has holiday sales. I’ll use the D500 at home on a tripod w/ the 200-500 for bird photography. Glad to know I’m not the only one who feels this way !

The Canon adapters allow you to use all your existing Canon lenses with no penalty. In fact, even if you have non IS lenses the R5 and R6 IBIS give you substantial IS to your lens. If you get the EF to RF adapter that has a drop in polarizer you can polarize any lens and do not need to buy the large diameter polarizers for various lenses. My 8-15 fisheye gets the benefit of IBIS and I can use the drop in polarizer with it. That is a real gamechanger with that lens to help saturate the colors in vegetation. You can also use the drop in neutral density filters to help with long exposure situations. I teach photography and get to experience a wide variety of equipment. This new R5 is a very special camera. For fast action with animal eye focus it is remarkable. Even hummingbirds in flight are possible with a high degree of success with the new animal eye focus. I have tested it on a large variety of animals, running animals, flying birds, slithering snakes. Even though the eye focus is supposed to be for dogs, cats, and birds I have had it lock onto the eyes of several insects (praying mantis for example). Even if it does not find an acceptable eye it will latch onto the head and follow it. I have used the R5 with all of my main wildlife lenses and it performs flawlessly (600 f4, 500 f4, 400 DO ll, 100-400, 100 mm macro, 65 mm macro). However, the RF 100-500 will be a significant light addition to your bag. You can also keep all of your current Canon glass.

CANON woke up and started to compete in the mirrorless world!
