thank you for your message , I read it many times , it's a smart reflection , I have a combi volkswagen( it's my usual car ) and I love it because it's a combi and nothing else . So I keep my Konvas M1(0ct 18) in the original condition and I try to use it like that . I have 4 originals lens 28mm , 35mm , 50mm , 75mm in oct18 it's not enough ? I try to found a larger and longer lens and I need a mattbox . About anamorphique lens I dont know exactly what is the differents solutions , I saw real anamorphique lens ( expensive ) I saw a anamorphique lens adaptateur to put in the front of the lens ( one is sphericle and one is square ) and onother one to put in the back of the lens . What is the good and not expensive solution ? Best regard Thierry (excuse my bad english Sorry )
