Sony Alpha SLT-A33 review – Verdict

Sony Alpha SLT-A33 product shot front angleThe A33 undoubtedly opens new doors and Sony’s clear-cut commitment to pushing new technology into the photo market is 
an interesting angle for a company looking for new approaches to capture today’s demanding audiences. Digital technologies are changing and it has to be said so are consumer’s expectations. While a year or 
so ago many noses would have turned at the mere suggestion of an Electronic Viewfinder the technology has come on 
in leaps and bounds. It may still not be perfect and, indeed, the EVF may be the A33’s greatest challenge. Though that sounds rather cynical as, in actuality, the A33 is an innovative, super-fast and top quality camera that feels much the same as using a ‘new age’ DSLR camera. There are one or two small improvements that could be made, but all things considered, this is new technology pushing the boundaries. The super-fast autofocus in live view and continuous focus burst modes actually work a treat. An exciting development that looks to be a step further towards the end of DSLR cameras as they once were – and not in a negative manner.
