Trying to decide between 5d IV or EOS R! Help!! If I go with R, Which Rf Lens should I go for? 50mm is my favorite focal length, 85mm is my favorite look of portraits, and I love the idea of the 28-70 being so versatile!
Here is my experience having (had) BOTH the R and the 5D4...
Bought the 5D4 to have “the best” I could afford. Never really pushed it’s limits. Used it for landscape, wildlife, and real estate work.
Bought the R because I like cutting edge and new stuff. Figured I would keep both and use the “better” camera for whatever task I was going to do.
Three months went by and I never touched the 5D4, more importantly never missed it, and loved the R so I sold the 5D4.
Don’t be put off by the “It can’t do sports” or “It can’t do BIF” folks. Granted it isn’t as good at those things as other cameras due to a “lessor” AF system it still certainly CAN do them.
If fast action sports and BIF is your PRIMARY photography to the near exclusion of almost everything else. It probably isn’t the camera for you, but then again neither is the 5D4 (as far as I am concerned) without the benefit of a crop factor and lower density of pixels, unless you have the coin for a 600mm lens you probably would be better off with a 7D2 for those things.
If you want a “Do everything, most things well, some things awesome, and a few things adequately” camera, than the EOS R totally fits the bill and for about $800 LESS than the 5D4.
I don’t think enough can be said about the lack of needing to Micro-focus adjust lenses, that alone increased my satisfaction with bird shots. I’d rather have my keepers be perfect focus, even at a lower rate than have a higher keeper rate of shots that don’t quite nail focus because the adjustment was off.
Other random thoughts...
-AF with 2x TC on the 100-400mm? No problem on the R - can’t do it on the 5D4.
-Want the reach of a crop? 1.6x mode on the R that several folks have said result in better shots than simply cropping in on FF shots.
-Knowing exactly how your shot will look before hitting the shutter. Instantly see how changing exposure settings will effect the shot beforehand
As for lenses, the kit RF 24-105mm F4L is a great lens. I have decided to go to the RF lenses and am selling off most of my EF lenses. Just received the RF 15-35mm and planning on picking up the 28-70 F2.0L. With these I am expecting to sell off my EF 100mm F2.8L macro, EF 11-24mm F4L, EF 50mm f/1.8, Tamron 24-70 f/2.8 G2, and probably my Tamron 85mm f/1.8 as well.
I expect I will keep EF 70-200mm and EF 100-400 II for now, no RF options at this point.
Here are a few shots from my first attempt at BIF with the he R (before the firmware updates that have only improved AF tracking)









. The 24-105 is just going to be a general/walk around lens. I don't really need F2.8 anymore and it is half the price. Still has CA on outsides like the original 24-105 but far less distortion and the corners aren't too bad. I hate CA. It did surprise me. 100% crop at 105mm.
