• […] check out my mini review of the XF100-400. I’ve been having tons of fun with this one all summer. It’s a pretty cool […]

    I like it too, and agree with the point you make. Wonder though whether you notice any change in battery life when you useit, compared to other lenses. In my case it seems to eat up batteries considerably faster, using it with X-T1

  • Dan says:

    Karsten, you’ll see increased battery drain with any of the OIS lenses over the non OIS lenses. I don’t know if they 100-400 would draw more power, but given that it has more and bigger pieces of glass to pull during focusing, it’s certainly possible that it would drain batteries a little faster. I’ll do some research on this and get back to you.

  • Thanks Dan, you helped me realize that even the focusing itself, with heavier lens elements will likely use more power, especially as I as I probably tend to focus/refocus more often than I do with lenses with a wider dof.
