Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Konica Minolta 5D and Sigma DP1x side-by-side from the front, back and top in their relative dimensions. Konica Minolta 5D has external dimensions of 131 x 93 x 67 mm (5.16 x 3.66 x 2.64″) and weighs 670 g (1.48 lb / 23.63 oz) (including batteries). Sigma DP1x has external dimensions of 113 x 60 x 50 mm (4.45 x 2.36 x 1.97″) and weighs 250 g (0.55 lb / 8.82 oz) (including batteries).
Below you can see the front-view size comparison of the Konica Minolta 5D and the Sigma DP1x. Sigma DP1x is clearly the smaller of the two cameras. Its body is 18mm narrower, 33mm shorter and 17mm thinner than Konica Minolta 5D. As you can tell, actually this is not a fair size comparison since Sigma DP1x has a built-in lens but Konica Minolta 5D doesn't. Once you put a lens on 5D, its thickness will increase significantly.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sigma DP1x is significantly lighter (420g ) than the Konica Minolta 5D which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on 5D, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Konica Minolta Maxxum 5D (Dynax 5D) nor Sigma DP1x provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Konica Minolta 5D and Sigma DP1x's LCD screens have the same diagonal size of 2.50 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
