How come bridge cameras can offer so much zoom?

2013/04/05

Nowadays many compact cameras can offer 25x-30x zoom. But having similar kind of zoom is not possible in DSLR cameras where it is mostly limited to around 11x-15x.

The reason why compact/bridge cameras can offer this (at a reasonable price) is these cameras have much smaller sensors compared to DSLR cameras. Thus, these cameras need much smaller lenses to cover that sensor. If you notice lens specification of these cameras they are usually at 4-100 mm range. While in DSLR, these are 18-200 mm range. Since DSLRs have much bigger sensors, they need massive lenses to offer long zoom range. This makes the lenses heavy and expensive.

So even though you can get away with very long zoom in smaller cameras, the image quality will be much inferior compared to DSLR’s APS-C or full frame sensors.

Why DSLR cameras take better pictures?

2013/01/27

We know that usually DSLR cameras take much better pictures than compact cameras. But why?

This is due to 3 main factors. Firstly DSLR cameras have much bigger sensor. Typically these are APS-C or full frame size. Compact cameras have much smaller sensors which capture less details. Secondly, DSLR cameras usually have much better quality lenses. Thirdly, DSLR cameras offer lots of manual adjustments which allows photographers to have much better exposure and composition.

There are some bridge cameras which use APS-C size sensors. If these cameras use good quality lenses, then theoretically images taken by these cameras will be comparable to those taken by DSLRs.
