Wide Angle Adapters? In: ANAMORPHIC Posted January 3, 2016 tbh for anything bigger than 4k mode on gh4 and slow lenses there are slim pickings. Everything available is for small chip use. Hence why I had to go through all the effort of manufacturing the ff38 and trump38 attachments. I've been looking at the ultra wide attachment recently released by sony for the 28mm/2 fe lens. this might be an option for those using anamorphics with small front elements. however it looks as if the electronic connections force the 28mm main les down to f2.8 in order to stop users trying to go as wide as f2 and getting poor results. The FF38 and TRUMP38's are the only wide angle attachments that really deliver good performance wide open at f2 (or even f1.4), but the use of the ff38 is limited to 50mm on full frame or equivalent.
