The RF-EF adapter supports all EF-S lenses too. The drawback is the 1.6x crop is enforced by the mirrorless cameras, reducing the pixel resolution down to the 7MP to 10MP range, depending on the original full-frame sensor. Now, you're a half to a third of the image resolution of full frame sensor, where you could have been using a cropped sensor body with these lenses and have all the resolution of the cropped sensor. A lot of new money to spend on a camera to obtain images with less resolution than cameras from about 2006 onward.

I have a Canon 6D and I have a 5D4 and a RP. The choice between the 6D and the RP would be the RP hands down, and you did say ". . .under $1K for a body . . . ?

i have both the 6DII, previously having the 6D as well, and the RP. The 6DII has always performed flawlessly but since I got the RP the 6DII has been sitting in the bag. The RP is smaller and I find that I get the best images that I have have when shooting indoor without flash or in low light. Both shoot fabulous images, so can't go wrong with either one. I also have the EF adapter and use my EF lenses on the RP just as I would on the 6DII.

Yes, plus with software updates, it will have "eye focus".
Plus technology marches on. . .

Good morning. Good question as to fitting your need with another camera. My answer, the Canon 6DII. I bought one when it came out, and I use it for most of my photography. This camera takes very good photos. And Canon makes dozens of lenses for it. At one time, the 6DII was the smallest full-frame DSLR on the market.

To aid your choice, rent one to try before you buy.

Good luck.

Real user story- not numbers from DXO or similar. I went from a Canon 90D to the Canon R6. I have not owned a full frame for several years and I am amazed at the image quality (gasp) and relative low noise at high ISO of the R6 (even a year later) While re organizing my photos this summer I had a chance to compare photos from both cameras - from RAW files- and noise was noticeable at ISO 1600 with the 90 D. I used the Canon 100-400 mm lens on both cameras using the Canon adapter on the R6 and then the 100-500 mm lens (when it became available). I have taken pictures with ISO at and above 6400 (R6) with good success. I will add that I used the 90D for a year and found it to be a difficult camera to work with in terms of getting accurate focus of moving subjects while the R6 is a huge improvement especially with its eye detection activated. I know you didn't ask about the R6 performance but hope this helps anyway in your decision.

This is all fantastic real world experience. Exactly what i was hoping for. I really appreciate everyones input!!

I recently bought a RP as a replacement for a 77D which I used for hiking, climbing, etc. Like you, I wanted a small, light, relatively inexpensive full frame. I also bought a RF24-105 4L to go with it. It's the only R mount lens I have so far. I've also used several EF L lenses with it. I found the RP a joy to use. Mirrorless is the way to go. I especially like the flexibility of controls and improved AF. Another benefit that few have mentioned is after taking a shot, the playback appears in the viewfinder and you can choose the info that appears with it. I find it useful to look at the histogram and then make adjustments, if needed, without ever taking my eye off the viewfinder. Most importantly, it takes beautiful images. I was so smitten with it, I went ahead and replaced my 5D IV with a R5 as well which I hadn't planned to do for some time.

At this juncture in the medium, and if you are serious, look to mirrorless, even if it means waiting a bit until you have the resources. Get the mirrorless lenses for mirrorless bodies or you are starting out with a handicap from the get-go.

Is this statement correct if shooting in Live View (which I do 99% of the time)? I've always assumed that my camera (Canon 6D2) uses a different focusing system for Live View that it does for viewfinder shooting.

EF-S lenses will mount on the RP using the adapter. However the resolution will be reduced to around 10 MPixels because of the lens crop factor.

I don't have either camera, so these are just my thoughts about them based upon what I have seen, heard, read, etc...

Both RP and 6DII are full frame, 26MP cameras. Both have a fully articulated rear LCD Touch Screen and the same ISO range (100-40,000 native, expands to 50 and 102,400).

The mirrorless RP is selling for $1000 and is significantly smaller and lighter than the 6DII. It is rated to be able to use slightly higher ISO. This is probably mostly due to the RP's 1-generation-newer processor and improved firmware. It also has an electronic viewfinder that can be very helpful in low light conditions with it's "exposure simulation". The RP's AF system covers almost the entire image area (vs 45 points that are largely centered) and has face/eye detection. It can shoot 4K video (vs HD in the 6DII).

The biggest concerns with the RP might include that it uses the smaller LP-E17 battery (vs LP-E6N the 6DII uses) and is rated to get far fewer shots per charge. Because it's EVF uses a lot of power the RP is rated to be able to do 250 shots per charge, while the 6DII with its optical viewfinder is rated to do 1200 per charge. Neither camera has a built in flash, which is another heavy draw on camera batteries. This may or may not be a concern, depending upon how many shots you typically shoot in a day. If it's a lot, extra batteries might be needed.

Some other concerns include that the RP is slower shooting. It's max is 5 frames per second, where the 6DII can do 6.5 fps. Also during continuous shooting the RP's EVF will have some "blackout" (later R-series do better at this). Look on Youtube for RP reviews by Froknowsphoto (Jared Polin) and others. Some of the reviews demonstrate this by directly filming what's seen through the viewfinder. This blackout may not be any concern unless you do a lot of long, continuous bursts, it's something many people become accustomed to and there's actually a little blackout with an optical viewfinder like the 6DII's, too... though it's less noticeable.

To use your existing EF lenses on the RP will require an adapter. Many users report little difference in focus performance with adapted lenses. In fact, many find them to be sharper, because mirrorless cameras like the RP have no need for focus calibration because their focus sensors are located directly in the image sensor, on exactly the plane of focus.... where DSLRs use mirrors to redirect the image to AF sensors, usually located in the bottom of the mirror box. The alignment of the mirror is critical and there's usually some very slight error, which can be corrected to an extent with the camera's Focus Calibration feature, on a lens by lens basis.

In a DSLR like the 6DII there is some light "lost" to the semi-transparent mirror used to redirect the image up into the viewfinder. The RP is mirrorless, so the AF sensors get 100% of the light transmitted through the lens. As a result, the RP is rated to be able to autofocus as low as -5EV, two stops lower than the 6DII. This means the RP needs only 25% as much light for AF to function. Another benefit of this is that the RP can work with "slower" lens/teleconverter combos... The 6DII is pretty good for a DSLR, able to focus "f/8 combos" with at least one and sometimes more AF points (with select lenses and TCs). But the RP can focus with f/11 and possibly even f/16, with most or all it's AF points.

The RP also has a more sensitive metering system. It covers the range from -3EV to +20EV, compared to 1EV to +18EV in the 6DII. However, the 6DII has a larger range of Exposure Compensation available: +/- 5 stops, compared to +/- 3 stops in the RP. Both cameras have the same mechanical shutter range 30 seconds to 1/4000 second and both have a 1/180 flash sync. Both cameras are fully functional with Canon EX flashes.

The RP has a "silent mode" using an electronic shutter. But unlike some other mirrorless, it does not offer any faster shutter speeds than the mechanical shutter. Note that electronic shutter can have problematic "rolling shutter" effects with some types of lighting and with fast moving objects. The upcoming and far more expensive R3 is using a back side illuminated sensor for much faster readout in an effort to minimize these problems... only a truly global shutter where the readout is instantaneous across the entire sensor will ever completely eliminate rolling shutter effects.

The 6D Mark II is selling for $1400, body only. Neither the RP nor the 6DII have IBIS. They both use SD memory cards and have a single slot.

Both cameras have self-cleaning sensors. The 6DII has an advantage that it's sensor is deeper inside the body and hiding behind a mirror and a shutter most of the time, which helps protect it from dust. The RP's sensor, on the other hand, is fully exposed any time the lens is removed. Plus it sits pretty far forward in the body. It's likely to be more susceptible to dust... and some care must be taken not to touch or damage the sensor during lens changes. (Note: This is a problem with other mirrorless, too. However Canon has made changes to later models so R6, R5 and presumably R3 have shutter that by default closes over and protects the sensor any time the lens is removed.)

The 6DII can optionally be fitted with a BG-E21 vertical battery grip that doubles battery capacity, as well as providing helpful secondary, vertical controls (the Canon OEM grip costs $200... there are cheaper 3rd party clones that perform similarly, but may not be as nicely made or durable). The RP is not designed to work with a battery grip and Canon doesn't offer one. 3rd party manufacturer Vello does offer an inexpensive one, but it's rather "funky" in how it works. It does increase battery capacity and provide a grip, but the only secondary control is a shutter release button and for that to work an external cable wire needs to be connected to the camera.

The future is mirrorless. Canon is adding RF-mount lenses regularly, has 25 of them now and more planned for the future. We will probably have over 30 to choose among this time next year. At the same time, Canon is discontinuing EF lenses and hasn't introduced a new DSLR model in a year or two. Within the last couple months Canon announced 24 EF/EF-S lenses were no longer going to be available, out of a total of 80 or 90 lenses total in that system at it's peak of production. There had been some others discontinued more quietly prior.

In the end, if it were me making this decision, based upon your criteria, between these two models I'd choose the RP. Compared to the 6DII, the RP's upsides greatly outweigh a few mostly minor shortcomings. And it's a move to a system with a future, rather than hanging in with the older system that will be gradually phased out over the coming years. (This is from someone currently using a bunch of EOS DSLRs and around 20 EF/EF-S lenses... who will sooner or later end up transitioning to the mirrorless cameras, too.)

I have a Canon refurbished 6D MkII with very low shutter count I’m trying to sell. If interested, you can contact me at <wph-mw@sbcglobal.net>.

amfoto1 Loc: San Jose, Calif. USA

You are correct. When using Live View, the 6DII switches to Canon's "Dual Pixel" AF with sensors embedded directly in the image sensor itself, very similar to how the RP and other mirrorless cameras focus. This is true with all the Canon DSLRs since introduction in the 70D (2013), except the most entry level models.

Dual Pixel AF (DPAF) is a form of phase detection and covers almost the entire image area. Phase detection focusing used to only be available via DSLRs' viewfinder AF systems. Phase detection is a lot faster than "contrast detection" AF that was used in both in Live View and in many earlier mirrorless cameras.

I am not familar with the 17-50 and 11-18 but are they EF too and no EF-S? Any way I think you have enough EF lenses for the 6D or the RP. I do not like the mirrorless but many people do so it's personal and this is an important factor to go mirrorless or DSLR.
