Yes, it is a K mount lens! That aperture lever should never have been bent, unless there is a particular reason for it! You just straighten it up and there you go!

Take the lens out, fire the shutter in B mode without film and back cover closed. With a light behind, look through the mirror box to trace the leak!

Mount a 645 120mm + adapter on a K body and then mount a SMC K 120mm on the same K body and compare!! Thatīs all you need!

NO, NO. A 80-160 645 lens with the 645xK adapter will still have the same FOV in 35mm as is in 645. Try to find the 645 x K adapter manual and read carefully!! I have several 645 lenses and they have the very same FOV in the 35mm format as the K lenses counterpart.

That would be true IF you mount a 645 directly on a K body. As that is impossible and an adapter is needed for that what makes the 645 lens to behave the same as the K lens in terms of FOV.

Yes, Sintra, Quinta da Regaleira is a must but booked with a guide! Lisbon is very nice for street photography around Alfama and Mouraria, Bairro Alto. Just walk around with your eyes open! :) For Sintra take the train, don't go by car!

If you go north to Porto (2,5 hours by fast train from Lisbon) you'll find it addicting, just walk downtown near the river and don't forget to visit Livraria LELLO one of the most beautiful architecture you can find.
Evora is SE of Lisbon, and Guimaraes NE of Porto are also worth a visit.

Enjoy portuguese cuisine!!

Again I was reviewing the K-3 II review and what I supposed to be a solution is not feasible unless you use a 360 or 540 flash. :(

Maybe it is an early firmware to ask for high ISO and other issues!

---------- Post added 03-03-16 at 08:13 ----------

As per other comments here, maybe it's a focus issue not a SR case !! He seems to be using a manual focus lens and short in time to get it critically well focused. I would concentrate on other items besides focus if reviewing in such conditions!

Not quite !! How can you adjust such a wide ISO range with ON/OFF ?
How can you select from 3 drive modes in CH/CL with ON/OFF ?
How can you enter BKT bracketing value with ON/OFF ?
Others ???

The variable aperture on these lenses has nothing to do with exposure choices but rather with ease of lens design only!

Adapting Pentax 645 lenses

Not quite !! You cann read from the description on each adapter, like this:

" Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. "
