Hello, the adapter should be used with manual lenses from the analog era, logically. On an Olympus E-PL7, I was curious about the usability and above all the achievable image quality. Since of course there is no electronic data exchange between the camera, lens and lens adapter, the camera or the image stabilizer should/can be set first to prevent camera shake Reduce. To do this, press the OK button, bring the image stabilizer to the desired setting. Then simply press the Info button and set the originally used focal length at the bottom right and you're done. The lenses came, to name just two, the Olympus G-Zuiko 1:3.5/28mm and the telephoto lens Olympus E-Zuiko 1: 4.0/200 mm. Of course, these are also used analogously on an Olympus OM-4 Ti. The adapter is well made and makes a solid impression. However, he has a slight lateral play on the bayonet. I guess less than a millimeter. But this doesn't affect the focusing at all, at least not with my lenses. I've experienced other things, and even without an adapter solution. So nothing earth-shattering, especially not at this low price. Of course it will then the camera, with the adapter and, for example, a G-Zuiko 3.5 28mm no case more suitable for jackets, and at almost 630 grams also heavier than, for example, with the Lumix 1:1.7 25mm at almost 490 grams. I like this Lumix, no question about it, but compared to the G-Zuiko 3.5 28mm, it seems to be attached to the camera, I would say "less high quality". If you have problems with manual focusing on an E-PL7, for example, I can recommend the Olympus VF-4 attachable viewfinder. The thing is great, so it can be adjusted well without a sectional image and/or microprism ring, as is the case in many analog cameras. Of course, focus peaking can also be used, but this function must then be assigned a button in the menu, e.g. the Fn button for quick access. The test JPEG photos I uploaded are all unprocessed and show quite good sharpness, colors and contrasts. My conclusion: Recommended and inexpensive adapter solution, but also with a slight tolerance on the bayonet.
