Night time is always a time for magic, as long as the air between you and the subject is clear and there is sufficient light (For your subject), and you have a tripod with you.
Beyond that its a mater of not being too cold. Having gone out yesterday I had taken some pictures of downtown Vancouver using a Sony NEX7 and the 55-210 Lens.
Camera was on the tripod, lens seemed to be auto-focusing very nicely, ( I have to say I am very impressed with the Sony NEX-7 and the E-Mount lenses). Even though the 55-200 is a fairly basic lens it looked like some nice shots were coming up on the screen. Being careful I checked them at 100% on the camera screen … and they were blurry. On a tripod? Using a 2 second shutter release? Why?
Well what I found that the SONY NEX7s OSS (Stabilization) must be turned
off in order to ensure a sharp shot on a tripod. Strangely, my Nikon with IS/VR turned on (weather on a tripod) does not interfere with the shot if the camera is on a tripod. With the SONY NEX7 they were coming out blurry with a shift to the right and slightly up.
I checked the tripod, tightened it, focused, re-focused, put on a 10 second shutter delay, then a 2 second, then walked away just in case my personal gravity was affecting the camera. Then thinking perhaps its the stabilization (OSS) that was being weird I had disabled it and voila fantastic pictures.
The shot attached is a 2 frame HDR combination with EXIF of the second shot attached (first one was one and a half stops lighter).
