Flowers -- NEX-5N & Schneider-Kreuznach Retina-Tele-Xenar 135mm f4 DKL. Click for larger
I do not like lenses with very long minimum focus distance, and this Schneider Tele-Xenar lens has a four meter (or 14 feet) minimum focus distance. Totally rules out any sort of close ups. The picture above is the best that I have been able to get. In comparison, the Tamron 135mm f2.5 has a "close focusing" of 1.2 meters (4 feet). This limitation really detracts from the fun of photography.
