Mirror lenses!

Not typically mirror, but a great shot Michael!

I mean wonki as in distorted lines in the image, not in the viewfinder. Perhaps I have to produce a sample to illustrate.

Hardly ever had a problem with black bands but that is probably because here we generally have a shortage of light while you have an abundance.

I'm not perfectly happy with the focus accuracy. I have not yet checked but wonder if the camera lost the setting I had in it. The last I saw, the LA-EA5 did not support the Reflex on my A7II. I may have to do the MonsterAdapter modification. So the wonkyness is because of silent shutter. It makes sense. The LA-EA5 requires latest generation cameras like A7RM4. Even on A7M3 it doesn't work. It's either a new camera or a Monster Mike!

An advantage of the Monster adapter chip with the reflex is you can move the focus point .
With all Sony cameras and adapters your stuck with center spot AF only .

I have the reflex along with an LA-EA5 and a7Riv , but I'm considering modifying my LA-EA4 for that reason ( and just that lens ).

Where did you learn/see that? I find that very interesting. It would also change the flange distance, I presume.

Baffle modified, re-inserted. I hope all systems are still go, don't have a way of testing it so I'll have to patiently await a VECTIS adapter.
