Have you ever wondered what the inside of a steam locomotive looks like. Yesterday the Durango & Silverton shop allowed me to get inside a 1928 steam engine that is being rebuild. Was a tight space so glad I had the Z7 with 24-70.
I love my D850 and battery grip, but I am glad I had the Z7 when climbing up a ladder and into the boiler. May get to ride in one of the engines and the space is cramped, so will take the Z7 again.
