your absolutely right. my k-1 focus is way off the scale.
i took the questionable route, and entered debug mode. slide auto focus fine tune over +120 micrometer (maximum in debug mode), and the lens is still out of focus!
so on top of the +120 um adjustment in debug mode, i added +5 to the auto focus fine tune in the menu, for this particular lens.
i think the view finder auto focus is even sharper than live view now... but that may be a placebo effect. :lol:

Thanks for the tip on GhettoCal, seems like this lens is going back to the seller if i cant help it.
Left: Live view single point AF Zoomed 100% 1:1, Chart in focus, however, ruler is pointing that focus was around 0.5.
Right: +10 adjustment, live view auto focus. Auto focus is still off, ruler is pointing that focus was around 1. As a result, even with +10, the lens is still back focused, which is in line with all my previous test.
I have also did the same with -5 just to test, and +6 +8 and finally +10.
At +10, it was the closest to the live view auto focus. however, +10 is definitely not enough for this camera/lens combination.

Pic 1 in this post - auto focus via view finder, single point af with +10 adjustment - auto focus is better than +7, however, still backfocused.
Pic 2 in this post - auto focus via view finder, single point af with -5 adjustment - just to show i'm adjusting in the right direction - auto focus is miles off...
Should i return this lens as its still under returnable period?

Sorry about the banding in the first two live view pictures.
Focus point was the strongest lit up section of the pole.
Two second timer was used, plus tripod.
Pic 1 - live view manual focus.
Pic 2 - live view single point auto focus.
Pic 3 - auto focus via view finder, single point af with 0 adjustment - auto focus way off.
Pic 4 - auto focus via view finder, single point af with +5 adjustment - auto focus still off.
Pic 5 - auto focus via view finder, single point af with +7 adjustment - auto focus even still off.

all of my auto focus lens are at least +7, however, i also have Samyang/Rokinon manual lens with focus confirmation.
Both of my manual lens at 0 give me precise confirmation for focus. so i'm not sure if the body is significantly off. or all my auto focus are off.

I'll try to do another test tonight. but yeah, the 100 WR is purchased used, and still within return period. i just dont want to do any unnecessary return if i can help without sending it for service.

yes, im testing it on the tripod.
i guess my method is not as good as the others, but its definitely still backfocused.
1. magnified the screen, and manual focus to a point, take a shoot. perfect focus.
2. auto focus to the same point, take a shoot. back focus.
3. focus adjustment to +10, auto focus to the point, take a shoot. still back focus.
I've used this same method with my 40mm XS and FA 50mm 1.7, and their back focus was both fixed with +7 adjustment.
I believe my copy of the 100mm WR need more than +10 adjustment?
Btw, i did tried on both far and near subjects.
1. subject right under my tripod. so about 1-2 ft.
2. subject around 6-8 ft away.

My two other lens (40XS and FA50) was corrected using +7 adjustments.
With the 100WR, +10 was able to improve the backfocus by alot, however, i believe it need something like +13/15.
Is there anything i can do myself before sending either the camera/lens or both in to Ricoh/Pentax for service?
Thanks,

I love my FA 50 1.7, but since the DA 40 XS is my lens cap for the camera, its my pick for the normal prime.

I want all new Tamron lens on Pentax LOl...
SP 150-600 SP 35 45 85 SP 70-300 SP WHATEVER
Only if Pentax and Tamron are under one roof... then they can be like Sigma, where they produces lens in multiple mount, including their own Sigma mount.
Sigma - SA native mount, but also nikon/canon/sony/m43/etc
Tamron - PK native mount, but also nikon/canon/sony/m43/etc

Both statement are true, and i agree having the best dost compute into most meaningful images. i do not intent to argue this point.
i'm not arguing anything in terms of what'll make you the best image... you can purchase k5ii and pentax-a lens kit for less than $500 and make better image than people who have kit that worth $15k.
i'm just saying, when you compare the most recent camera/lens selection from these three company, it make you wonder what makes these modern DA lens so much more expensive.
