Good to know and thank you for posting this.

Canon sells three different adaptors, and third party people make some also.

Some of the EF mount lenses actually work better on the RF bodies.

The adaptors: straight adaptor, adaptor with control ring like the RF lenses have, adaptor with control ring and slot for drop in filters.
I have 4 EF* bodies and a bunch of lenses. I now have two RF** bodies and the lenses are starting to pile up. I also have 2 adaptors for those two bodies.

I have a "plan" to thin the herd but every time I decide on what to sell, trade or give as a gift I have second, third and ???? Thoughts.

*80D,90D, 7DII,5DIV
**R7, RP

This is what I do with my R7 using a Canon EF-RF adapter. I expect all manufacturers have an adapter for their DSLR lenses for use on their mirrorless bodies.

Which do you like better, the 90D or RP?

Architect1776 Loc: In my mind

The reason I keep the EF lenses is that they work perfectly on my RF mount cameras as well as the EF mount cameras. I don't plan on disposing of the EF cameras thus I need EF lenses. So with EF lenses working 100% on both, there is no real compelling reason to get RF lenses to replace them.
I will get RF lenses if desired to fill a need/want like the Canon 200-800mm lens or something not available in EF.

The RP is a full frame RF mount and the 90D is a crop sensor EF mount . Apples and Oranges.

Actually of all my bodies the 90D is my least favorite. I got it to use on my 150-600 for birds because of the high MP sensor, but I had trouble with the AF keeping up with moving birds and went back to using the 80D on the big lens and tripod. I loved my 7DII for birds etc. until I began to want more MP for large prints (80D), the R7 is kinda its rebirth as an RF mount body and I love it.
The 5DIV was for wide angle work and dim light and the RP was my pick of the RF mounts, small, light and less expensive than the R5 or R3. Then I found that it takes excellent pictures.

My last expedition for water birds, I took the R7 with RF 100-500L and the RP with a wide angle zoom. The RP was hanging around my neck and the R7 was in the cargo pouch of my mobility scooter when I was moving. I went a bit over a mile up and back along a man-made river in a flood control channel. It was built as a joint project of a university, large local business and the city park department.* It has ponds, islands, rapids, a couple of small falls, dams and trails on one side (both sides on some stretches) with foot bridges every so often. The whole thing is landscaped with flower beds, shrubs and water plants. The main pond has an island and roofed observation platform in the middle, with a raised walkway to get out to it. The place has a lot of birds, esp. migrants in winter, as no one pays attention to the "Do Not Feed..." signs. The winter visitors are just starting to arrive. I saw song birds, stilts, coots, gulls and several kinds of ducks and a few egrets. When the migrants all arrive later this month, there will be multiple types of geese and even more types of ducks.

All the bridges are wide enough for my scooter, which is 5' long and 2.6' wide. It is for a single rider with cargo or two riders without a cargo basket or duffle bag.

Oh, I have a street legal mobility scooter with lights for night. My doctor gave me a letter to get one for my lower back problems, pinched left sciatic nerve (the whole leg hurts and feels weak when that flairs up) and a left knee I have injured 4 times in my life. I should be able to recover part of the price at tax time, since my Doc said I needed it to avoid too much walking.

It is great for photography in parks, along bike and hiking trails etc. If they are not too far I don't even need to use the car carrier, I just ride there. My weight and at top speed the batteries last 20 to 30 miles. For someone under 200lbs and on more or less flat pavement, it can get 40–50 miles on a full charge if you just sort of cruise along. The manufacturer turned off the "speed limiter" (governor?) for me, so I have hit 31mph. This year, CA changed the law on speeds for street legal mobility scooters. Seniors (I am 78) and those with disabled plates (me) can do 30mph on the streets instead of 15. It is now legal on streets with 25mph limits(35 if local PD say OK, mine does) or in bike lanes, on hiking trails etc. It is ADA compliant so legally can go anywhere a pedestrian can go as long as it fits, and it is safe to do so. Some larger stores with roomy aisles let it come inside since it just a bit longer (about 6 inches)and not as wide as those riding shopping carts they have.

*CEO of the business got tired of looking a large concrete ditch out his office window. So he contacted the University and they designed it, then with money from the business the park department built it.

Wow!
Quite a story(s). Back when I decided to upgrade from my XSi, I was looking at the 80D. Then the R came out. Too smart for me. Or just too complicated. Then the 90D popped. I almost pulled the trigger. But then the RP showed up. I had been seriously thinking of going full frame, a lot less money than the R. Started doing detailed comparisons of the three. I found the RP to be less complicated than the R. In fact, it seemed to be very equivalent to the 90D. Mirrorless meant the end of lens to body focus problems that I had with the XSi. Then Canon put it on sale and included a lens adapter. BANG!

I think I made the correct decision for me. Focus is a lot sharper on my photos with any of my EF and EF-S lenses I already own. Then as I see fit ($$$), I can upgrade to R lenses. I was considering the higher MP sensor of the 90D but decided that I really did not do that much deep cropping nor do I pixel peep. My collection of lenses takes me from 18mm through 300mm. Close enough. And from what you said about it, I'm glad I decided against the 90D. Thanx for the personal impressions.

I've been going to the same Massage Therapist for many years trying to straighten out the muscular kinks that the medical field fail to deal with. She hooked me up with a Feldenkrais therapist and then a chiropractor experienced in Applied Kinesiology. These three people have done a lot to keep me moving. The chiropractor is amazing in his ability to find the real cause of my problems and to straighten them out. There are days when I get out the cane, mainly to help me get up and down stairs. But even those days are getting further apart. There are muscles I can't reach like my massage therapist, I can't do what the chiropractor does, but I have used what I have learned in Feldenkrais and modified it to my own needs.

I split my leg bone from the knee down, skiing. Plus, I put a lot of undue stress on the left knee using a 3200-pound racing clutch in my daily driver for many years. Sometimes I'm surprised the knee still works. About three years ago I had x-rays taken from scull to pelvis. Everything looked good till it got down to the last vertebrae. Where every other joint had been even across the last or next to last joint was twice as wide on one side as the other. My comment was, "That explains a lot."

So, I understand. And when I feel bad, I think of my 80-year-old sister with a fused left ankle and foot and curvature of the spine. That ain't pretty! I will think of you, too. I wish you luck. Weather you decide to try any of my routes is up to you. Like every other profession, there are good and bad.

Again, thank you for your response. It is much appreciated.

What has weight got to do with improving the viewing and focusing system ? Weight would be more an attribute of format size than of viewing system.

EF lens can be adopted to the R cameras. Canon has an RF to EF lens adopter. Have one and it works perfectly.
