>>3319727I use them all.
Everyday I pick a camera, choose a lens and head out for my day.
Usually walk and take pictures on my lunch break.
Cameras are Full Frame, APS-C, MFT, Q.
All my lenses are manual.
Have adapters so all lenses can be used with all my cameras.
At the moment I have just over 300.
Everything from Super 8 lenses to medium format.
Most expensive lens was a $200 Hasselblad.
All from garage/estate sales, Craigslist, flea markets, a few from Fleabay, Goodwill and other thrift stores.
Watched YouTube and learned to clean and service most of the lenses.
I realize I have a problem.
But I have limited myself to no more than $200 per month.
Have a searchable PDF of all the lenses I own in my phone, just in case I come across an interesting find.
Just started creating profiles for each lens, on each camera, for use in Photoshop/Lightroom.
Recently my favorite combination has been a 80mm Pentax medium format lens paired with my Pentax Q-S1.
One camera, one lens, makes for a great day.
