Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Sigma SD1 and Sigma SD1 Merrill side-by-side from the front, back and top in their relative dimensions. Sigma SD1 has external dimensions of 146 x 113 x 80 mm (5.75 x 4.45 x 3.15″) and weighs (including batteries). Sigma SD1 Merrill has external dimensions of 146 x 113 x 80 mm (5.75 x 4.45 x 3.15″) and weighs 790 g (including batteries).
Below you can see the front view size comparison of Sigma SD1 and Sigma SD1 Merrill. In this case, we can see that Sigma SD1 and Sigma SD1 Merrill have the exact same height, width and thickness.
Now lets look at the top view comparison of Sigma SD1 and Sigma SD1 Merrill.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sigma SD1 is 790g lighter than the Sigma SD1 Merrill but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since both Sigma SD1 and Sigma SD1 Merrill have the same Sigma SA Bayonet lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Both SD1 and SD1 Merrill have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
