Like you, I started in the early 2000's with the first DSLR Rebel. I then went through two other Canon camera bodies and landed with the 5D Mark III. Gosh but I loved that camera but I got into birds and needed more pixels so I made the jump to the R5 body and lenses. I can't tell you I don't love it but it's a sophisticated piece of equipment and I only got to shoot with it for five months before I had surgery and was laid up for five months. Now it's like starting all over again and I'm missing my 5D but I know it's just a matter of getting back on that horse again. I sit here and I wonder, however, if they are going to grow the R5 lineup the way they did the 5D. And then I wonder what the R5 MII would look like???? I have some problems with the camera. The battery life is frustrating but doable but shouldn't have happened at all but I knew it when I purchased it so I'm rather OK with it. I have had some burst problems. And when I went to shoot it last week there is a problem when I put my Hood Lens up to the LED screen, the picture goes away as if I were putting my eye to the eye piece and it never did that before. But the camera sat for five months without use and I failed to take out the battery. Could that be causing a slight electrical problem ,not sure. I usually don't purchase new camera models but rather wait for the upgrade. I haven't decided if I'm trading up this body should Canon go this way. Do I regret my decision to purchase now, not really. I mostly regret having to relearn the camera all over again!!
