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 Fujifilm SL1000 and Nikon D90 side-by-side from the front, back and top in their relative dimensions. Fujifilm SL1000 has external dimensions of and weighs 659 g (including batteries). Nikon D90 has external dimensions of 132 x 103 x 77 mm (5.2 x 4.06 x 3.03″) and weighs 703 g (1.55 lb / 24.80 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm SL1000 and the Nikon D90. Fujifilm SL1000 is 9mm narrower and 14mm shorter than Nikon D90 but it is also 46mm thicker. As you can tell, actually this is not a fair size comparison since Fujifilm SL1000 has a built-in lens but Nikon D90 doesn't. Once you put a lens on D90, its thickness will increase significantly.
Here is the back view size comparison of the Fujifilm SL1000 and Nikon D90.
Now lets look at the top view comparison of Fujifilm SL1000 and Nikon D90.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm SL1000 is 44g lighter than the Nikon D90 but we don't think this will make a significant difference.
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 D90, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Fujifilm FinePix SL1000 nor Nikon D90 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
Fujifilm SL1000 and Nikon D90's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Fujifilm SL1000 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Nikon D90 has a fixed type screen which provides less flexibility in shooting positions compared to SL1000.
