Hello !
Recently I received two lenses for my two Pentax cameras (K5-II and K3-II) the lenses were the Pentax 18-135 ED AL DC WR and the Tamron 17-50 2.8 EX DC HSM OS (why do they love those long names?) andI foun d that both ones were with back focus.
Then I decided to check all my lenses with the LensAllign and Focustune. Here are the corrections I'm using with the K5-II.
Sigma 17-50 2.8: +6 (same correstion at 17 and 50 !)
Pentax 18-55 (kit lens) : 0 for 18mm and +2 for 55mm, decided to apply +2 and it's acceptable.
Pentax 18-135: +2
Pentax 40mm Limited: +1
Pentax 50mm 1.8: +2
Pentax 70mm Limited: +1
I still need to work on the Sigma 18-35 1.8 Art. I'll do when a have more time, using the Sigma USB dock.
After this, I'll do the same with the K3-II
Do you use AF microadjustment ? If yes, on which lenses and bodies ?
Cheers !

Reason: Correction, back focus instead of front focus
