This is the door to the driver’s compartment on a Connex suburban train here in Melbourne.
I did have my long lens (a Sigma 70-300mm) with me, but my normal everyday lens, a Sigma 18-125mm, was more than adequate for the reasonably tight frame that I wanted.
I do not crop, enhance or post-edit my images in any way. Shot with a Pentax K100D using a Sigma 18-125mm lens. F8, 1/125 sec, ISO 400, focal length 98mm.
