Really the only time I use my MF stuff is for the posed formal shots, most of my candids are an on the run situation, that lends itself far better the the 35mm format, just in ease of moving around, the one exception, is I have used a Mamiya 645 hand held with a good flash for candids, but still it is quite a bit larger than the 35mm bodies which does not lend itself to moving as easy, and off course the cost of AF medium format is to great for my blood.

Like I said, 35mm works great when I am in a moving and changing enviorment and have found the 105mm zoom to work great for what I am doing.
