M42 to SONY E-mount camera connection.
I have the purely manual adapter of the fourth generation. It also seems just as sophisticated.
Due to their design, older analogue and digital SLR cameras have a greater distance from the sensor or film to the flange focal distance of the lens coupling than modern mirrorless compact or even full-format cameras.
This adapter is therefore theoretically just a tube with the corresponding camera and lens connection to restore this distance. There is no mechanical or electronic transmission of lens data and no lenses whatsoever. On one side there is an M42 thread for holding the lenses, on the other the SONY E-mount bayonet connection for the camera. The length (the flange focal distance) is obviously perfectly adjusted, so that I have been able to use all lenses in the full focus range without any loss of sharpness. Internal reflections can be ruled out with this generation, as the matt black interior is very finely grooved.
The adapter from K&F Concept is made entirely of metal and is accordingly heavy. This also gives it a very high-quality and solid feel. The thread is very clean, burr-free, fits perfectly and is well made. There is no play or jamming here.
The orange-copper colored ring corresponds perfectly visually with the E-mount connection on SONY.
The E-mount connection also fits perfectly. It clicks into place well and then sits firmly and completely free of play.
The groove structure on the outside of the adapter makes it very easy to grip and can be connected very easily even under adverse conditions. The coating and even the labeling are very high quality and will certainly last a long time.
The adapter is very well packaged and even comes in a high-quality resealable plastic box. I made an insert out of dark foam so that I could also transport the adapter in the box. Unfortunately, only bubble wrap is included here. A small, sturdy fabric bag can be used in the camera backpack as an alternative. Perhaps an idea for "5 stars plus".
I admit, I initially wanted to buy a simple adapter to test. Now I'm glad I chose this one. At the same time, I have now favored the corresponding “K&F Concept” accessories.
Impeccable workmanship.
Highly recommended.
The trend is towards a second adapter.
This means I can leave the adapter permanently on frequently used M42 lenses.
