Using the Sigma 30 1.4 DC DN on a Sony fullframe mirrorless camera

Looking for a poor man's fast 35mm prime lens, I tried to hack the Sigma 30mm f1.4 DC DN Contemporary lens, made for APS-C mirrorless camera. Unfortunately it didn't act like the Sigma 30mm f2.8 Art lens: removing the rear plastic baffle didn't effect the strong vignetting. But, with a little post-processing crop (easy to do with a batch crop in Lightroom over hundreds of pics in just few seconds) I can obtain a nearly 38mm field of view with a f1.4 max aperture. This lens gives good sharpness, good contrast and saturated colors and also a nice bokeh. --- This video is made with: Sony a7sII camera - http://amzn.to/2mRiCpq Sony 50mm f1.8 FE lens - http://amzn.to/2m9OiSF Davinci Resolve 12.5 In this video: Sigma 30mm f1.4 DC DN Contemporary lens - http://amzn.to/2nezTpS Sony a7r camera - http://amzn.to/2mt9XHj Music: Branches by Malaventura http://freemusicarchive.org/music/Mal...
