I'm 56 and that's not on the timeline yet.
To the OP, I love my Fuji 150 6.3, been shooting with it for 30 years. Just got a Fuji 135 5.6 and it's OK but I'll need to get a little more comfortable with it.
I would recommend a 135 to 150 lens paired with a 210 to 240 and get use to those lens. Buy quality.
