I'm a 100% digital photographer. I need to buy a regular non-digital unit for some special effect as I cannot afford a very highend digital. Now I got this unit in my hand that I borrowed from a friend. Give me your opinions on it, without knowing the price. the kit include: Minolta X-700 Minolta Auto 280PX Flash Minolta MD Zoom 35-70mm 1:35 Minolta motor drive Vivitar Macro Focusing auto Zoom 70-210mm 1:35 w/ UV haze Vivitar 2X-5 MC Tele-Converter So?? worth it or not?
