Sony NEX5n/SAMYANG 8mm
Philadelphia

First test of a new spherical panorama acquisition setup.

Camera: Sony NEX-5N, manual mode, 1/50 sec, auto-HDR(5EV) jpeg.

Lens: Rokinon 8mm/3.5 fisheye (EOS mount) on Fotodiox adapter, f/3.5.

Shots: 4-around up 30 deg interleaved with 4 around down 30 deg, nadir.

Not 100% thrilled with the auto-HDR, but it is convenient and way better than a single exposure.  Note flare at bright windows.  Unfortunately the maximum bracketed exposure is only +/-0.7EV, so HDR raw sets will require manual intervention.  Don't have the IR remote yet so can't say how well it will work for pole shots. 

The SAMYANG lens seems fine, not quite sharp enough to 'staircase' at 100% crop on this 16 MPix camera, but the 75 MP equirectangular is satisfactory.  At less than half the price of a Sigma 8mm, it is a major bargain.

More About USA

The United States is one of the most diverse countries on earth, jam packed full of amazing sights from St. Patrick's cathedral in New York to Mount Hollywood California.The Northeast region is where it all started. Thirteen British colonies fought the American Revolution from here and won their independence in the first successful colonial rebellion in history. Take a look at these rolling hills carpeted with foliage along the Hudson river here, north of New York City.The American south is known for its polite people and slow pace of life. Probably they move slowly because it's so hot. Southerners tend not to trust people from "up north" because they talk too fast. Here's a cemetery in Georgia where you can find graves of soldiers from the Civil War.The West Coast is sort of like another country that exists to make the east coast jealous. California is full of nothing but grizzly old miners digging for gold, a few gangster rappers, and then actors. That is to say, the West Coast functions as the imagination of the US, like a weird little brother who teases everybody then gets famous for making freaky art.The central part of the country is flat farmland all the way over to the Rocky Mountains. Up in the northwest corner you can find creative people in places like Portland and Seattle, along with awesome snowboarding and good beer. Text by Steve Smith.
