Recently bought this mirror reflex because I need something longer than my 55-210. Despite what many people feels about them, I actually find the Samyang (or in my case it is Richarm) quite good, it is hard for me to get the focus right every time, but practice make perfect The below pictures are taken from the ground, handheld in sun/cloudy afternoon with my Nex F3. The birds were on my houseroof and is quite small (around 7-9 cm). Since I shoot RAW I have applied my usual sharpening, and contrast/saturation etc. little more contrast and vibrance than usual though.
