Oh btw. the Windows calculator has Log10 (simply called "log") and LN (or "ln") but no Log2.
On to some other comparisons between both contenders:
Before starting some of the comparisons we have to decide which lens
to put on the D300. The Canon has a 5-20mm lens which is equivalent to 28-112mm on a film/FF-body plus it has stabilization. That lens would be equivalent to a 19-75mm on the D300. For size, wheight and price-comparisons let's take the Nikkor AF-S VR DX 18-55mm 3.5-5.6G If you consider that the D300 has 10% more linear resolution than the Canon you get the field of view of a 60mm lens, when you crop a shot taken at 55mm focal length down to 10MPix.
So feature-wise the Canon has the benefit of being 20-30% longer than the standard kit-lens for the Nikon.
The Canon also has a max aperture of f/2.8 – f/5.8. So it's a little brighter on it's widest setting.
But the major limitation here is that you cannot change lenses with the Canon. But this is the general benfit of DSLRs vs p&s cameras.
In summary I'd say 1.5 points for the Canon 870IS, 1 point for the Nikon D300.
From the catalog: 155g for the Canon vs. 825g for the Nikon, both without batteries. But wait: the Nikon is body-only so we have to add 265g for the 18-55 VR lens. Now adding the batteries we end up with 185g for the Canon vs. 1170g for the Nikon, a difference by the factor of 6.
But I will not award Canon 6 pts. for this but only 1 (Nikon-fanboy that I am
Uh oh, another category where my beloved D300 will lose another point
Guess, which camera fits easily in your pocket!
Another point for the Canon 870IS
All incl. 19% VAT from a reputable dealer. So you need to invest 6x as much in the Nikon DSLR as in the Canon p&s. Funny though, that this is the same factor as with the weight. So you get 1g of the Nikon system for the same price as 1g of the Canon, namely 1.20€
So practically this is a draw
Ok, just joking: 1 point for Canon
So after the first round it is 4.5 pts for the Canon vs. 1 pt for the Nikon
Let's see whether the Nikon can recover from those blows.
Next up is screen-size and resolution, weather-sealing and frame-rates.
