So, after a good play with the analytics tool I've managed to come to a few conclusions.
1) I did a 6 year year run over two catalogues and proved to myself that going to Fuji was the right thing to do. My wildlife shots have tended to be what I did most, and over the last 2 years over 50% of my catalogue has come from my 100-400 with or without the 1.4TC. In the previous 3 years, I shot less than half the number of images on my 7D2 & 150-600. Confirming that as my new kit is lighter, it goes out more often.
2) Removing the 100-400 from the analytics shows that the 10-24 and the 50-140 get similar use. That surprised me as I don't take the 50-140 out that much, but when I do, it gets a lot of use. Not sure how it will stack up in the future now I have the 90mm though.
3) I hardly ever use the 60mm - I think it's time to move it on.
4) I don't use the 35mm f1.4 that much, but when I do, it's almost always used at f1.4 - f2 (as you would)
5) I used the 16mm f1.4 more than I thought I did (before I swapped it for the 90mm). So will you guys stop talking about it as you're going to get me in trouble!!!
What a useful tool though....
