Gear that was actually end game for you.
•1• Was sorting through my Onedrive and came across my A1 reciept, did a double take when I saw it was 2021 that I purchased it. Where has the time gone. The A1 is my ultimate camera, so much so that if it died, I'd get another.
In my 100% biased opinion, it was Sony's greatest achievement, even surpassing the original A9, as it had no quirks.
•2• Then there was the Panasonic Leica 200mm f/2.8.
A lens that is so incredible, that I sold my Nikkor 500mm f/4 to move over to M43.
When I shifted away from M43, I gave up completely on Bird Photography as no lens could match the PL200. Simply the most beautiful rendering, and outstanding sharpness.
