The difference is the adjusted focusing - so if you have problems for example with front-focus, you can try a different

...that's the way I fixed the autofocus of my 100mm Macro WR.
edit: added new lensrom for HD D-FA 28-105mm.
I had luck and still guaranty for my lens - so I send it to pentax and they adjusted the focus.
Hello Duc,
Thanks for your reply.
I tried to use your database because I failed to export the lens ROM file in the debug mode of my K3ii. When I pressed the “Lens ROM Camera->SD”, the screen turned black for a short while (less than 1s), and then nothing happened. When I put your Lenseep file in the SD card and pressed the “Lens ROM SD->Camera”, nothing happened too. So I don’t know how to do to deactivate the SDM of my DA 16-50.
In Chinese forum, some guys succeeded deactivating using K5, K5ii and K5iis. But nobody succeeded using K3ii.
Do you know something about it?
My English is not very good. Sorry for my wrong (maybe) expression.
Cheers,
Cheungyu
edit: nothing happened means that lenseep was not created in my sd card after "camera -> sd"
