ZEISS 21-100mm T2.9-3.9 Lightweight Zoom LWZ.3 Lens (MFT Mount, Feet)

This lens is the equivalent of having a set of CP.2 primes in the form factor of a zoom. There's zero focus breathing, beautiful bokeh, beautiful micro contrast. We just used this lens on an Fs7ii for a feature narrative film, and people have been commenting on how great it looks. I thought I would explain why: it's this lens. The focus is smooth, and we kept it mostly at an T4.5 except for a few scenes. You'll definitely want a focus puller if you're wide at 2.9. It's advertised at being a T2.9-3.9, but none of us could tell the difference really. It looked great at all ends of the zoom range. There was no discernible difference in sharpness wide or telephoto (like most zoom lenses out there). Just know that it's very large, and will weigh down your camera. In theory it would work for doc work, but would be a lot to carry, and would probably be intimidating toward subjects. For narrative work on a budget, I can't recommend it enough. it's better contrast, sharpness and focus breathing than the Fujinon MK series, and leaps and bounds better than any photo zoom lens. I can't recommend this enough.
