A walk with a 50mm CCTV lens

A morning walk with the camera, this time testing a 50mm f/1.4 CCTV lens adapted to fit a mirrorless camera.

So far this lens seems optically the best of the three CCTV lenses I am testing. But one of the main reasons for experimenting with these lenses is their strange optical behaviour around the edges of the frame and in the backgrounds of images so this lens is a bit of a disappointment so far. I wasn’t expecting a $41 CAD (including shipping and the adapter) lens to be this good.

A Periwinkle flower after some overnight rain with the lens wide open at f/1.4. The flower seems to be fairly sharp considering it’s close to the edge of the frame and the lens was wide open.

Old seed pods and new leaves. I had photographed these seed pods last winter and was surprised to find that they were still on the plant months later surrounded by new leaves. Again, the seed pod seems fairly sharp even though it’s away from the center of the frame.

The Periwinkle is an introduced species in North America. Some people regard it as an invasive species to be controlled.

It is rarely sighted in lil red dot nowadays as Periwinkle is a poisonous plant and it gave way to more “friendly” plants as parents worry kids get poisoned plucking the flowers.
