We've done a fair bit of camera comparing in On Landscape and one of the things that causes a lot of confusion is how to work out equivalent focal lengths, depth of field, apertures and exposure is the part that sensor size plays in the equation. We've talked about them a little bit in previous articles but thought it would be good to cover things in  little more detail. This should also help any of you that use crop sensor cameras such as APSC and four-thirds.
