This Sigma 70mm f/2.8 DG Macro received an 80mm front ring to allow matte boxes to clamp-on easily, the front cap to fit the front ring, and a seamless 32-pitch delrin focus gear to smoothly pull focus.
This particular client had a shoot some time ago in which this lens was able to produce the high quality visuals he needed, but also gave the opportunity for exploration. The Cine-Mod gave him the ability to take his creativity a few steps further.
"...I searched and tested for several hero lenses... I needed to get them geared up, fronted out, and up to snuff to pull focus and accept filters - and fast! For many years now I've been bringing my weird lens things to Duclos Lenses and the team there was not only able to turn these Cine-Mods around with much haste, but essentially delivered them to me. Many high fives." - Phil Holland
