hi all,
I'm currenlty an XT20 user with 18-55 and 50-230 XC. for the last 15 years, i have been a still object/landscape guy. Few family members have picked up all kind of sport lately, so i naturally took up the photography duty. Last weekend was London triathlon, there were few places (under bridges mainly and some indoor shots understandbly) that the system AF really struggled to track objects accurately (say, at 150mm-200mm, aiming at rider about 20 meters away, weather was overcast, and both rider and myself are under an overhead bridge. i was shooting around 1/250, iso 1000, F6.3. AF seems to have switched back to CDAF instead of phase detection). Should i be looking to get a faster lens, say 50-200mm/ 50-140mm, or should i be lookinig at something with more advnaced AF system like XH1?
I also have a A7rII + 70-300mm G which i didnt think will perform any better in those light, but im quite out of touch with camera stuff in the last two/three years, do correct me if you disagree. Thanks
