The listed weight difference is a bit less than 300 g (255g). This is without batteries though; the MZ-S uses those little toy ones and the F100 uses AA. With batteries the difference is more. Unless, of course, you don't like little toy batteries, and you get the battery grip for the MZ-S. The the size,weight and cost of the two cameras even up. I still think that comparing the two cameras is an apples ond oranges situation: they are two very different cameras for different types of users.
From: Sylwester Pietrzyk ...And F100 has over 300 g of weight more than MZ-S... it costs a solid couple of bucks more, and it still lacks some nice features of MZ-S: wirelles flash as a standard, MRC, leaving film leader out after rewinding, reading exposure information for each frame requires expensive add-ons (software for PC)... - This message is from the Pentax-Discuss Mail List.
