Sigma’s 18-35mm f1.8 Gets Converted Into a Cine Lens


The Sigma 18-35mm f1.8 hasn’t even been out for six months yet and a company has already converted it into a cinema lens with full manual aperture control. The conversion was done by GL Optics, who is a China based company that specializes in optic conversion. The lens is still for APS-C sensor cameras–though it has been known to work on full frame cameras but with vignetting.

The killer is the price. Sigma’s 18-35mm f1.8 is under $1,000 but the GL Optics conversion will run you $3,500.

We reviewed the 18-35mm f1.8 and rated it an Editor’s Choice, and DxOMark believes so as well. The interview about the lens by DSLR News Shooter and the sample video are after the jump.

Also, don’t clean it with vodka.
