Coming sunday I leave for another travel to Surinam which is in South America.. Last time I brought my 5D with all lenses and the E-P1 with 14-42 and 17mm. I almost made all shots with the E-P1. My best shot which gets published and is on an exhibition was however made with the 5D... When I returned I bought the 20mm in order to get the same quality in sharpness as my 5D. The E-P1 is still not a 5D but the 20mm made it much better in terms of IQ.. What shall I do.. Bring the whole lot with me again so I feel ok although my back will be broken after the travel or shall I give the E-P1 the chance to prove itself as my only cam this time.. This is my current Pen set..
