Q: 1. can i use this adapter for M42 mount Pentax Takumar 135 f2.5 lens on my sony a7ii? Are focus to infinity and diaphragm rings working in manual mode?

A: First, a short primer of the lens: The Pentax Takumar and Super Takumar 135mm f2.5 lenses have a single stop-down pin to enable the Pentax film camera to operate the auto aperture. The latest version SMC Takumar lenses also have an auto-indexing lug and very small pin near the M42 threads to lock the auto/manual slider. All versions of this lens have an auto-manual slider: in the auto position the lens closes the aperture via the stop-down pin; in the manual position the lens aperture ring directly controls the aperture.Now, the first question, can i use this adapter for M42 mount Pentax Takumar 135 f2.5 lens on my sony a7ii?. Yes, this adapter fits the Sony A7mark2 and the M42 thread Pentax Takumar and Super Takumar lenses. It does NOT work properly with the SMC Takumar lenses due to interference with the auto-indexing lug.Are focus to infinity and diaphragm rings working in manual mode? The adapter allows focus to infinity. The 135mm f2.5 Pentax Takumar and Super Takumar lenses have an aperture control ring, and when coupled to this adapter, they will work with in manual mode. The adapter has a small internal flange to depress the auto aperture pin, so the lens can be left in auto mode and the aperture ring will act manually, just as if the lens was placed in fully manual mode.All the above said, all inexpensive adapters have considerable manufacturing tolerances, so there may be slight inconsistencies among the same brand and type adapter.

Q: 3. Will this work with Sony Alpha 7III for Super-Multi-Coated Takumar lenses f1.4/50mm? or the f.2.5/135mm? I read there is a difference between SMC and Super-Multi-Coated marked lenses.

A: As long as the lens has a M42 mount that adapter will work to attach to a A7 III. It is a manual adapter. So, you need to set your A7 III in the menu (Camera Settings 2) to Release w/o Lens.
