A blanket of buttercups

I was out again yesterday with my Nex-6 and Pentax smc 50mm f/1.7 prime lens and noticed the buttercups making a carpet of yellow under the trees next to the main route to Hertford, I thought is made a nice contrast to see the flowers slowly growing next to the busy main road so I got down low and took these shots with the cars an out of focus blur.  I had to use the back panel lcd on these as I couldn’t got low enough to see through the viewfinder and found the manual focus magnification quite useful to pick out one flower and focus on it.
