I have two leaf aptus backs which I am just about to sell as my work has become more location 35mm based over the last couple of years.
I have an Aptus 75S which has about 14,500 actuations.
I also have an Aptus II 7 which is totally unused and has zero actuations.
I have had two leaf backs for some years now and have periodically upgraded them to keep up to date. I had a backup 22MP Leaf which I upgraded
2 years ago to the Aptus II 7, and as the 75S has worked flawlessly since I have had it, I have never needed to use the Aptus II 7, hence zero actuations.
Both backs were bought new by me and have not had previous owners.
If either of these backs are of interest to you, please get in touch
As you are probably aware, they are both 33MP backs.
If either of these are what you are looking for, I'll leave it to you to suggest a price.
