Ahh I seem to have miss represented my question some what.....
I realise that with a 2" you can get eps with a wider field of view, what I was wondering was that if you had a 2" 30mm with say a 67 FOV and a 1.25" 30mm with a 67 FOV would you see any difference?
Why, I hear you ask? Well I am thinking of getting a longer focal length ep, but for the most part they use a 2" barel, and to fit it I need to get a 2" visual back and angle, making it quite an expensive investment for only a single ep. However I did notice that in some models the ep comes in both the 2" and 1.25" variety, hence if there is no visual difference then I wouldnt spend the extra on the 2" (if that makes sense).
