Sold my M3 to buy M4. Blasting fast autofocus makes this camera perfect for me now.

I found the most useful camera for my work...."#sweepstakes"

The Sony Cyber-shot RX10 IV sets a new standard for all-in-one superzoom models. If you're interested in getting an all-in-one travel camera, or simply want to photograph your local wildlife without needing to buy a huge zoom lens for a DSLR, it's the best you can buy right now.

Huge zoom range covers almost any photographic opportunity; Fast; accurate autofocus keeps moving subjects sharp; Excellent image quality in most lighting conditions

Screen only tilts up or down, Lacks some expected features, e.g; intervalometer, Bluetooth under-utilised (only used for geotagging

The Sony Cyber-shot RX10 IV is a premium all-in-one bridge camera with a 20-megapixel 1-inch sensor and a long-range 24-600mm equivalent zoom. Styled like a small DSLR, it costs £1799.

The Sony Cyber-shot RX10 IV is in a league of its own. No other bridge camera handles and performs so well. In this class, image quality is excellent. Detail at f/4 and f/5.6 is sharp from centre to corner across the majority of the zoom range.

I've owned this camera for a month now, and use it mainly for birding, the IQ is stunning at all focal lengths even with the Clear Image setting, which gives you a massive 1200 mm. Also have adapted it with a 1.7 tele extender using step up/down rings, this gives me 2024mm, ridiculous really, the IQ...

Durable; Great Features; Great Picture Quality; Lightweight; Simple Controls

I purchased this camera to use on a vacation to Newfoundland. I do quite a bit of hiking there and I wanted to reduce the wait that I normally carry when using a DSLR. I am very happy with the features this camera offers. One feature that I would like to have would be a digital ND filter.

As a dedicated Canon user and having a somewhat lesser view off Sony historically, I have to say this is a brilliant product. Slightly noisier in low light than I would have preferred but that is not to say I am probably being picky, used to Pro cameras as I am.

For a wildlife shooter and at times a sports shooter I have not found a camera that has given me the ability to stop a bird in flight. To freeze a surfer on a maneuver that would make you feel that this has one big wow. I have focused on a insect and a jet flying.

Calling the RX10 IV a “bridge camera” does it a disservice – it’s a fantastic choice for those who want a well-rounded, do-it-all camera, especially for travel. Wildlife photographers also benefit from the long lens and fast frame rates. You pay a premium to own it, though.
