Recently released prime lenses from Tamron contain some unique features especially beneficial for filmmakers. The 35mm f/1.8 VC in particular is one of my absolute favorites because it is extremely useful under a variety of shooting conditions.
First off, for those shooting time-lapse photography at night, fast apertures are important. Using shorter shutter speeds means smoother motion and longer, more graceful shots in your finished product. The Tamron f/1.8 series of lenses is designed to shoot wide open, which means you have an additional 1 1/3 stops of light. This is a big deal. For example, if you normally shoot your night time lapses at 30 second exposures with an f/2.8 lens, you would be shooting at 10 seconds with the f/1.8—that is the difference between two frames a minute and six frames a minute!

Second, it has a ridiculously insane minimum focusing distance. At just under 8 inches, you have a maximum magnification ratio of 1:2.5. Basically, you never have to worry about backing up to get your shot in focus, and close focusing also increases that cool bokeh effect.
The Tamron f/1.8 family has an additional benefit unique to their prime lenses: a proprietary stabilizer technology called Vibration Compensation. The Tamron f/1.8 series is currently available in 35mm, 45mm and 85mm focal lengths in Canon EOS, Nikon F and Sony Alpha mounts.
