The new 21-100mm lens weighs in at just over four pounds and features a speed of T2.9 on the wide end, which linearly ramps to around T3.9 when fully zoomed in. It is a very smooth and fairly subtle transition as you zoom in, one that is almost unseen in these type of variable aperture lenses. The minimum focus distance for the lens is right at about 2.9 feet with a generous 300 degrees of focus rotation, making this an extremely flexible option for both narrative and documentary shooters. Designed to match with both Ultra and Master primes, this lens will make a nice addition to round out a kit and provide the flexibility lacking in prime lenses' single, fixed-focal lengths.
I had a chance to check out the 21-100mm, and I have to say I'm impressed. With a list price of $9900, it's a truly cinema-style zoom that's compact and affordable. It's sure to become a popular choice for many people thanks to its minimum focus breathing, a light and well-balanced feel, and overall ease of use.
The lens should be shipping by the beginning of next year, plenty of time to start practicing those dolly moves for your Vertigo effect shots.
