In some situations or using certain lenses I prefer the Nex-5N to the Nex-7. Certainly the ergonomics of the Nex-7 is better but I like to keep the native lenses on that camera. It really is a shame that the sensor doesn't like RF legacy lenses because there are some really nice ones out there. The shorter you go the worse the fringing becomes. I've had a hard time with some images from the CV 15 f4.5 lens. Very time consuming too so now I tend to use these lenses on the Nex-5N.
This image is one of my favouties that I have taken with the SEL 50 f1.8 lens. It has a certain 3D look and feel to it. I also like that the pink flower is so dominant even though there are other flowers to be seen.
