Just got my E-M1 a few weeks ago and loving it. Last week I had the opportunity to shoot some large church interiors with the E-M1. I normally would use my full frame D800 for this sort of work, but I wanted to try out my new Pan 7-14 and Rokinon 7.5mm fisheye. Needless to say I was very well pleased. The 7-14 is very sharp to the edges and shows very little distortion after Lightroom automatic straightening. All of the 7-14 images have been corrected in LR to eliminate most of the perspective distortions, while the fisheye images have not been corrected. All had some basic editing in Lightroom and a couple were combined from bracketed exposures in Photomatrix to be able to show the stained glass windows. A couple from the Cathedral Basilica in Covington,KY: http://bit.ly/1fg60Jc http://bit.ly/1hW7TPv and a few from churches in Mercer County, OH: http://bit.ly/1fg6ijg http://bit.ly/1hW86lX http://bit.ly/1hW8bWS http://bit.ly/1lJaIas The rest can be seen at: http://alpeter.zenfolio.com/p705811286 and http://alpeter.zenfolio.com/p1031806186 . Thanks for looking!
