Well, this morning at work a platter full of tasty pastry treats was brought to the office by one of my co-workers. I happened to have an old Nikon macro lens in the car attached to the new Olympus E-M5.
The lens performs nicely. (I've really liked it on some recent flower pictures.) Any problems with these images are completely user-error. Probably too little depth of field (i.e. only a small plane is in focus), as I was trying to keep shutter speed up and aperture nearly open.
And I got seduced by the macro capability and got too close. I think if I had moved back and got more of the treats into the image, it would have been better.
Anyway, these are hand held shots with an 105mm (210mm-e) lens, ISO 3200, no flash, at 1/160 and 1/200th second shutter speeds. There are no electronics to the lens so the aperture is unknown by the camera, and I have no recollection either. Best guess: F4.
