I have a Gossen Multi Pro meter. Ive been using it for over 8 years and its never failed me once. Since I started my 4x5 work I have been thinking of getting a spotmeter to have more control, I have also been contemplating getting the variable angle attachment for the multi pro as a much cheaper option. The VA attachment will give me a 7.5 degree meter, will this be enough for serious B&W work? Anyone using a VA attachment? Or should I just get a Minolta spotmeter F or Pentax Spotmeter V?
