What was your first Canon camera and lens?
My first dSLR was a Canon 50D which came with the 18-55mm kit lens, which I practically never used. The EF 400 f/5.6L quickly followed and then the EF 100-400 "dust pump". The 50D would have been purchased almost 20 years ago and was sold when I got the 1D Mark IV.
I then added the 7D, 1D Mark IV, EF f/2.8L macro, the EF-S 17-55mm (which had the IQ of an L lens) and the big EF 500mm f/4L + 1.4x TC. That remained my kit for about 14 years.
I've now finally upgraded to the R5 Mark II and still use all the above lenses for wildlife and added the RF 200-800mm for a bit more versatility (and much lighter than the prime). That will probably do me for the next 10 years 😂
