This is the Sony 500mm f/4 G SSM lens, a fast telephoto prime but for Sony A mount. The new FE 400mm f/2.8 GM OSS will set the bar for sports photos in the a7 and a9 lens line up

Today the Sony FE 400mm f/2.8 GM OSS lens has been announced. It fills a whole in the FE lens line up for the Sony a7 and a9 cameras.

It’s a hole that seemed to grow when the Sony a9 was announced – arguably the most capable camera for shooting the sort of action that such a fast telephoto lens like the 400mm f/2.8 is primarily designed for.

Currently the FE 70-200mm f/2.8 G OSS lens is the closest FE offering to the newly announced 400mm f/2.8 lens, but that has half the reach.

Existing a7 and a9 shooters currently need to use Sony A mount lenses via an adaptor to get the sort of speed and reach that the Sony FE 400mm f/2.8 lens offers.

Sony A mount telephoto lenses include the 500mm f/4 G SSM which retails at around £11,000. You also have the 300mm f/2.8 G SSM II at £7,500 and the 70-400mm f/4-5.6 G SSM II at £2,270.

Andrew Hall uses ferrofluid and sound waves to create captivating, abstract photography​​​​​​

Photographer Andrew Hall experiments with how liquids and gases interact with each other, using other influences such as sound waves and magnetic fields to produce abstract photographs.

To create the effect he pours ferrofluid, which has nanoparticles of magnetic material suspended in it, into a container three millimetres deep. Then he applies a magnetic field underneath while adding drops of pigment, such as paint or ink, which mixes with the fluid. "If the magnet's close, the fluid tends to go into spikes, but as I move it away, it morphs into the beautiful organic pattern you see here," Hall says.

In another series, Shooting Music, he plays with the same idea but the liquid, usually water, morphs in response to sound waves played through a speaker. Sometimes the music will be melodic; other times Hall will play a single, humming tone, causing the liquid to vibrate. "It kind of dances with the music. It's staggering stuf ... Read more »
