The Sigma 50-100mm T2 Cine High-Speed Zoom Lens (Feet) with a Sony E-mount provides an image circle that covers Super 35mm-sized sensors. It features a maximum T-stop of 2, and the aperture does not ramp over the zoom range. It shares common lens gear positions with the other lens in the Sigma High Speed Zoom lineup, which makes for rapid lens changes.

The 9-bladed iris provides round out of focus highlights for a natural-looking bokeh. The lens barrel features 180° of rotation from close focus to infinity, and the zoom barrel rotates 160°, and the clickless iris ring features 60° of rotation. All three lens control rings are geared with cine-standard 0.8 Mod gears and the focus scale is marked in feet. The front of the lens is 95mm in diameter with a removable 1/4"-20 support foot that helps support the lens with the aid of a 1/4"-20 rod-mounted lens support (not included).

All the lenses in the lineup are designed to comply with SIGMA's CCI standard simplifying when intercutting between lenses.

Sharing the same dust-proof and splash-proof construction as the SIGMA 150-600mm F5-6.3 DG OS HSM｜Sports, each ring and mount is sealed to prevent water and dust from entering.

The lens body is made completely of metal to stand up to the rigors of the production day.

The main lens markings are in luminous paint for easy visibility in low light situations. The intermediate markings are laser-engraved for durability. The focus and zoom markings are readable from either side of the lens.

The lens features a 95mm front diameter for compatibility with a wide variety of matte boxes and incorporates an 82mm front filter thread.

All three lens gears are standard 0.8 MOD and feature a damper that eliminates metallic sounds when you reach the end of the lens travel.

The lens includes a removable support foot.

A: We're afraid not. This lens only covers up to a Super 35mm sensor, it will not cover the Full Frame of the 5D Mark IV.

Q: 8. Love this lens but the ARRI LMB 4x5 mattebox 95mm clamp on adapter ring doesn’t cover the gaps on left and right side. In other words, because the lens hood has the cut outs on the left and right side of the lens, the mattebox adapter ring isn’t deep enough to cover those gaps. So, you have to tape the openings each time you use this lens. Or, is there a better solution? A deeper adapter ring? It needs to remain at 95mm so that it’s easy to swap lenses.

A: As an alternative, you can use a 15mm LWS rod system so you can mount the mattebox using ARLMB4515LWS and ARLMB45TFA. https://www.bhphotovideo.com/c/product/1341037-REG/arri_k2_0013427_lmb_4x5_15mm_lws.html https://www.bhphotovideo.com/c/product/1341036-REG/arri_k2_0014206_lmb_4x5_tilt_and.html
