Field of View for Loupes

So I did a little digging around and I've found that a lot of folks prefer loupes that have a wider field of view and was wondering why this was the case.

I know that 2.5x loupes will give you a view of the full arch while a standard 3.5x will only give you 3-4 teeth on one side.

However the prisma lenses provide an expanded field of view for 3.5x so that you'd get the 3.5 magnification and can also see pretty much the full arch...just wondering why this is better than only seeing 3-4 teeth using standard lenses!

Field of view or depth of field? I think my optimal loupes would be a 3.5 or so, and a high depth of field.

However if you are talking about field of view, seeing more is always better so I don't see why someone would not want a the widest view possible at the desired magnification...

Talking about field of view - just want to know why someone would prefer the expanded view prisma lenses (which are heavier and more expensive) over the standard ones.

I got the 3.5X EF because I liked being able to see the wider field. the only thing that sucks about having 3.5 magnification is the shorter depth of field, but it just takes some getting used to. As for the extra weight, it doesnt bother me a bit. Just strap the loupes to the back of your head and you'll hardly notice!
