I don't want to start a crop v full frame war (again), but just wanted to question one specific item here. The field of view you get with each sensor type.
Putting all other items aside, I often hear it said that full frame give a wider field of view for things like landscapes etc, that crop bodies just cannot match.
However, I am a little perplexed here - is this a false statement, or am I missing the point.
If I shoot with a crop body, do I not just need a shorter focal length compared to FF to get the same field of view?
i.e. at 12mm on a 1.6 crop is should give an identical image (in regards to field of view) as a 19-20mm lens on FF. Given that there are a range of lenses available, I am guessing you can cover similar if not identical focal lenghts, even when taking in the crop sensor effect.
Does this make the field of view question a non issue?
