As you may remember I am blessed to not be very weight sensitive, and also as you know things can change in a flash.
I am in the Nikon world but as my photography interests have settled down and narrowed down a bit I have sold off the Z glass just sitting in my dry cabinet. Many of the ones I got rid of were purchased when there were very few z mount alternatives.
Now with my focus on bird ID photography, the indoor and outdoor people stuff I do for church and the rare landscape type of shot and carrying two camera bodies on my holdfast money maker more often. And with the advent of 2 new Tamron Z mount lenses that fit my needs I have ended up with far more room in my dry cabinets. I sold off Z50, Z14-30, Z100-400, Z70-200 and ZTC2.0 and Z180-600.
My camera body collection grew by 1 with a Z6III added to my 2 Z9's. My lenses are now a Z800mm f/6.3 my most used lens, Zmount Tamron 150-500, Z600mm f/6.3, Zmount Tamron 35-150 f/2-2.8 my people photo workhorse, Z24-120. Those cover all the focal lengths etc. that I need for what I do.
I have one probable addition next year the new Tamron z mount 90mm macro. New lenses will come along and I may get a loaner Z400 f/2.8 TC from NPS some time and check it out and if it works logistically for me it could replace my Z600mm f/6.3. I hope I can stay better at have less overlap and fewer lenses just sitting in my dry cabinet in the future
