Originally posted by luftfluss I've noticed the red/blue 3D effect, too - like those 3D glasses in the movie theater - but in the case of your image I mentioned, it's more than that. I feel like I can reach through my monitor and touch the individual petals.
Interesting. I tried out a new (to me) lens today, the Pentax 67 100mm f 4.0 macro, highly regarded as one of the great Pentax lenses. It also produces 3D-like artifacts. I will be posting some of those photos later today, probably in Prime, Bokeh, and Large Flower clubs and maybe in the Medium Format photo section since I am using it with the 645Z camera.
