To kick things off, let me say there are no winners or losers. This is like a competition between toddlers at pre-school where everyone gets a prize. This isn’t a direct technical comparison between the two and it isn’t about proving you should buy one in particular. This is about guidance on how I made the choice between the two.
The Sony 70-200mm f/2.8 vs Sony 100-400mm f/4.5-5.6 is a common problem choice in cameraland particularly when it comes to sports. It’s not really as simple as putting a converter on the 70-200mm and putting them side by side, they perform differently with and without the converter. For me personally, the 100-400mm was my answer, but like anything, it isn’t the same answer for everyone, hence the reason this isn’t a one paragraph article.
Whilst I believe that Sony has the upper hand with autofocus, I would still like to see some of the autofocus customisation options from Fujifilm offered on Sony. There are some aspects Fujifilm also gets wrong on the autofocus side so this isn’t to say Fujifilm is better, more that there are lessons to be learnt for both parties.
I saw a video by Tony and Chelsea entitled “What’s the best mirrorless camera for shooting sports”. I guess what annoyed me about the video is that it seemed like the usual bloggers excuse to get as many mirrorless cameras into a single video, with links of course to purchase them via an affiliate link.
Commercial interests aside, what also concerned me about the article was the value of one piece of functionality over another. There are four things that typically differentiate a camera for sports: autofocus, high ISO capability frame rate and buffer. It’s not to say they are the most important for everyone, but every sports camera has had these over other non-sports orientated models.
