In early 2009 I bought my first Sigma, a dp1. I have been a life-long picture-taker, but that camera re-ignited my passion for photography. I currently use a Sigma dp2s and dp1 Merrill (dp1m). This review is a bit negative on the Quattro, but please understand that it is written from a frustrated lover of Sigmas,
I would hesitate to admit it, but if I had to take any lens to a desert island, it might be the $30 Fujian 35mm 1.7 c-mount lens made for CCTV video cameras. This is a lens never made to pass any DxO test. Until recently, I used it on an EOS-M; however, I needed a loupe or reading glasses because the EOS-M doesn’t have a view-finder.
I bought a focal reducer to use with my Nikon 24mm 2.8D on my Blackmagic Pocket Cinema camera. Getting an effective 0.7 * 24mm, or 17mm starting at 1.8 (1 stop reduction) intrigued me. Andrew Reid, the genius behind EOSHD, is a big proponent focal reducers. As a hobbyist, I couldn’t justify the cost of a Metabones adapter.
