 Up
until now auto focus has been carried out either by DC motor or Ultra
Sonic / Silent Wave Motors, however a new innovation noted by Monty Solomon
and reported in todays New Scientist may offer another option, especially
for ultra-compact lens systems. A company called '1 Limited' of Cambridge,
UK has developed a sheet of piezoelectric ceramic material which can move
whatever is placed on it (by using a grip and shift type movement), roll
it into a cylinder and you could move a small camera lens up or down the
cylinder (zoom or focus). At the moment this technology is aimed at camera
phones however I have no doubt that it could be important for lens systems
in ultra-compact cameras.

Canon's EOS R, the company's first full-frame mirrorless camera, impresses us with its image quality and color rendition. But it also comes with quirky ergonomics, uninspiring video features and a number of other shortcomings. Read our full review to see how the EOS R stacks up in today's full-frame mirrorless market.
No Nikon camera we've tested to date balances stills and video capture as well as the Nikon Z7. Though autofocus is less reliable than the D850, Nikon's first full-frame mirrorless gets enough right to earn our recommendation.
Nikon's Coolpix P1000 has moved the zoom needle from 'absurd' to 'ludicrous,' with an equivalent focal length of 24-3000mm. While it's great for lunar and still wildlife photography, we found that it's not suited for much else.
As a stills camera the Fujifilm X-T3 is a pleasant update to one of our favorite APS-C cameras, significantly improving the autofocus. If you're interested in stills and video, though, it's knockout.
The Nikon Z7 is slated as a mirrorless equivalent to the D850, but it can't subject track with the same reliability as its DSLR counterpart. AF performance is otherwise good, except in low light where hunting can lead to missed shots.
A question frequently asked on the Internet is 'what's the best DSLR?' In this buying guide we've answered that question – but also whether it's the right question to be asking in the first place.
What's the best camera for under $500? These entry level cameras should be easy to use, offer good image quality and easily connect with a smartphone for sharing. In this buying guide we've rounded up all the current interchangeable lens cameras costing less than $500 and recommended the best.
Whether you've grown tired of what came with your DSLR, or want to start photographing different subjects, a new lens is probably in order. We've selected our favorite lenses for Sony mirrorlses cameras in several categories to make your decisions easier.
