I have a 501 cm with an 80mm and a 120mm. I use the waist level viewfinder when I am shooting landscapes,etc. When I am working with people, I have a kiev prism viewfinder. It weighs a ton, but works good for when I am shooting people in a more dynamic environment where things are moving more quickly. I have an old Sekonic L-28 light meter and I meter frequently when necessary with changing light, but otherwise I do periodic readings and pay attention to the light. My lenses are T* coated, but I've read a lot of feedback from folks who think that this is not necessary. The "kit" option is a good way to buy...
one, because you get the package deal price which is usually better than buying each piece separately
two, you get what you need to shoot
three, there's a lot of them available because they sold a lot that way and people are selling them now...

I love my Hasselblad and Zeiss glass rocks. This may sound silly, but there seems to be focus latitude with these lenses...they are just so d*** sharp...
