So I finally got my hands on the R1 for this big track and field championship in Seattle next Friday and I am honestly a bit overwhelmed by the speed of this thing. Ive been shooting with the R3 and the 70-200mm f2.8 for a few years now so I thought I knew what to expect but this body is just on another level. The cross-type AF is insane but I am noticing some weird hunting when I am wide open at the long end and I am starting to think my current RF glass isnt quite hitting the refresh rate the body needs for that 40fps burst.
Ive got about 12k left in the gear budget for this quarter so I need to make a move fast before the event starts. I was looking at the 400mm prime but then I am worried about versatility for the closer lane shots. The problem is I need absolute clinical sharpness for these tight crops since the client wants high-res prints for the stadium walls. Ive been a Canon pro for 15 years and I have never felt like the camera was actually faster than the lens until now. Its kinda stressing me out because I need to get the order in by tonight to get it here in time.
I have already ruled out a few things based on the testing I did this morning:
- the older EF glass with adapters
- the non-L series obviously
- my current 70-200 which seems to struggle with the 40fps tracking
Which professional lens actually keeps up with the R1 sensor readout and AF speed without any micro-stuttering during high-speed tracking?
The Canon RF 100-300mm f/2.8L IS USM is probably your best bet for the R1 if you need to keep that 40fps burst usable. I have used this setup for a few track meets now and the difference in AF motor response compared to the 70-200 is pretty noticeable. The 100-300 uses dual Nano USM motors that are specifically tuned to handle the high-frequency AF calculations the R1 pushes out. The hunting you are seeing at the long end of your current glass is usually because the internal focus groups just cant cycle fast enough between frames. Its a physical limitation of the older lens architecture. With the 100-300 you are getting prime-level sharpness which helps with those heavy crops for the stadium prints. It handles lateral movement across the lanes quite well without losing focus during high-speed tracking. If you find 300mm a bit short for some of the field events you can pair it with the Canon RF 1.4x Extender. Tracking speed stays solid even with the teleconverter on. While the Canon RF 400mm f/2.8L IS USM is also an amazing lens it depends on your needs regarding versatility. The zoom is just much easier to manage when the athletes are coming straight at you in the final stretch. It fits right into your 12k budget and is probably the most balanced choice for the R1 sensor readout speed right now.
