Sample gallery - Canon RF 100-500mm f/4.5-7.1 USM L IS

A malfunctioning spot AF is not a big deal - if you know it. I reckon spot AF just doesn't work reliably with an f/7.1 aperture. On Sony cameras, the AF switches to a broader AF field, if it has issues. The EOS R sticks to the setting.

Note that the spot AF works nicely in lab conditions.

Yesterday I shot another set of 50 images mostly at 500mm. Most images were motion blurred (surfers) - which was my fault (in combination with the f/7.1 aperture) because the shutter speed was not sufficient. There was at least one shot which was sharp - albeit not usable because the composition was s**t.

One conclusion is certainly that it isn't a sports lens at f/7.1 - you just end with very high ISOs in such cases.

Well, time to get a different camera in that case. Smile

That's based on what I have seen from R5s and R6s, with this lens, and a bunch of other lenses, including the 600 F/11 and 800 F/11 ....

Kind regards, Wim
