This is a serious lens, finished to a high standard and able to be customized to the level befitting its premium billing. It appears to be very well corrected for aberrations and and capable of impressively sharp images – and naturally, none of this comes cheap.

The Sony Alpha 9 (or A9 for short) is a high-speed full-frame mirrorless camera that’s designed to go head to head with Canon and Nikon’s flagship professional DSLRs. It’s capable of shooting 24MP images at 20 frames per second while keeping focus on moving subjects, and costs £4500.

The Alpha 9 is capable of recording 4K video in the XAVC/S format at 25fps and up to 100MB/s, with a dedicated position on the mode dial that affords full manual control. It’s also possible to record files in a second, lower resolution simultaneously. In addition its S&Q mode allows Full HD recording at rates from 1fps to 100fps – in effect from one-quarter-speed slow motion, up to 8x-speed quick motion.

With a 3.68-million-dot resolution and 0.77x magnification, the A9’s viewfinder has one of the highest specifications on the market. It’s bright and clear, and easy to see into the corners even if you wear glasses. However the live-view feed doesn’t quite do justice to the panel resolution, and aliasing artefacts can often be seen in areas of fine detail.
