I have let myself tempted by curiosity zuzulegen this quite expensive adapters. After some discussion in forums Photo although were theoretical in nature, but also a good aufführten another aspect, I do not regret the purchase. Through the crop factor of approximately 2.7 when using the NX lens series with constant light intensity, the adapter is also a good teleconverter. For example, an eq from the 30mm 2.0. 2.0 / 85th The 45s would be a eq. 1.8 / 120th (This was an indication of a photo Board colleagues, I wanted to share with you.) With some lenses, the NX Series, one gets from the small Mini truly an amazing picture quality. The 30s and the 45s are good lens can also be used on the Mini with adapter as portrait lens. At the price a surprisingly good expansion of the NX Mini Systems. The tripod mount is certainly a bit inconvenient if you want to hang up the camera, but the problem arises for me, as I either use a small tripod, or hold the camera in hand. Can not remember when I've ever put a camera somewhere to take a picture myself. But everyone should decide for themselves. My Conclusion: Who uses anyway some lenses of the NX system has here by buying a Mini with this adapter a fairly low-cost expansion of its NX lenses. Especially as the Samsung NX Mini is considerably fallen in price. And the pancakes of NX System remains the Mini with this adapter "pocket-friendly"
