Hi Bob, Yeah, it really is impressive. I got the idea of trying DxO's stuff from an answer from Kelby to a writer's query in Shutterbug. My favorite thing is night on the street. Used to go out practically every night after dinner when I lived in Colorado Springs. In the sixties it was with one or the other of my Leicas. In the early 2000's it was with the 3.3 mpx Casio QV-3000EX. Nowadays I love going to St. Aug and walking St. George street at night. The result, of course, is noisy photographs. I've had reasonably good noise-reduction results from Nik's Dfine 2, but DxO OpticsPro Elite 11 is a whole new world. I'm not thrilled with the interface, and I'm pretty angry about their delivery method, but the software itself is great stuff.
The Pen-F is a mixed bag. Like its brothers and sisters it's loaded with crap, advertised as "features" -- stuff I'd rather not have on my cameras. If I want movies, for instance, I'll buy a movie camera. I haven't shot a film-clip with either of my recent Nikons or my Pen-F and I never will. You can't hang a movie on the wall.
On the other hand the Pen-F is small and black, like my Leica M4, but with an ISO range (it was ASA until the Kodak standard became "international") at least two stops higher. I've got a Panasonic Leica DG Summilux 25mm on it, which roughly is the equivalent of 50mm on its four-thirds sensor. The combination of f/1.4 and the Pen-F's built-in VR gives me even better results on the night street than I can get with my D750 with a Nikon 50mm f/1.4, which has no VR. The Pen-F also has a really good EVF, which helps a lot, especially at night.
My E-P1 was a good street camera. The Pen-F is even better.
