Back in 2007/8 during my degree at University of Wales, I was lucky enough to work at Jessops branch in Cardiff. I will never forget weird and fantastic cameras that would come in stock which was impossible to give the best advice to customers which one to buy - some wanted ''pink camera'', some ''£50 wonder camera'' while others were open to suggestions. Of course, price was always a deciding factor in most cases, from cheap, budget, bridge and high-end cameras and meet customers who came from different backgrounds and with different photographic need from expensive to cheap compact cameras. While cheap compacts are no longer popular, more advanced compacts are still important. Nowadays they have much bigger-sized sensors than most mobiles could ever offer – the bigger the sensor, the greater the distance needed between lens and sensor, so an unacceptably bulky smartphone would be needed. The cameras here have one-inch sensors or even bigger. On a smartphone sensors are about a sixth of this size (around 1/3 inches). Bigger sensors mean bigger pixels which are better able to suck in light accurately and faster resulting in less image noise and better photos in lower light. Megapixel count is a less important than image sensor, though ideally look for 12 megapixels or above. So, when your iPhone or Samsung just won't deliver desired image results, perhaps you should look to invest and purchase a powerful, pocket-sized camera instead. Below is just my personal guide on cameras under £1.000 which you might find helpful ahead of this coming Seasons holidays. 1. Panasonic Lumix TZ100: £549, Jessops The 20.1-megapixel TZ100 is another camera with a one-inch sensor but this one has a really great great-quality lens (from Leica) and lots more features than some, including 4K video 2. Canon PowerShot G5 X: £579, Amazon The G5 X has a one-inch sensor. What makes this 20.2-megapixel camera stand out is that it feels great in the hand thanks to an effective ergonomic grip. 3. Sony RX100 IV: £759, Jessops Sony’s RX100 series is brilliant, delivering power and excellent images from a highly compact case, smaller than many rivals here. The 20.1-megapixel model RX100 IV has a one-inch sensor, a pop-up viewfinder and solid build. 4. Fujifilm X70: £545.92, Amazon Fujifilm’s skill at advanced compacts is hard to beat – certainly the design and build quality really stand out against similarly priced rivals. 5. Panasonic DMC-TZ80: £359.95, John Lewis The Panasonic Lumix TZ80 looks great. It’s a compact but its whopping 30x zoom means you can get right in on the action. It has an 18.1-megapixel sensor with large pixels which are accurate and effective. 6. Canon PowerShot G9 X: £372.89, Amazon This camera is slim enough (31mm from front to back) to plop into a pocket, but it still squeezes a big one-inch sensor inside. It’s also very stylishly designed. 7. Panasonic LX100: £499, Amazon The sensor in the LX100 uses a system called Micro Four Thirds, slightly bigger than a one-inch model so even better at quickly, accurately measuring light. Any of these cameras will offer hugely improved images. Some are big ( Canon G5 X) and two (Sony RX100 IV and Canon PowerShot G9 X) are tiny. The Canon G5 X, Panasonic TZ100 and Panasonic TZ80 offer the best balance between power and value for money. Lastly and if by any chance you're looking something more powerful for both photo and video under £1k, then I couldn't highly recommend Sony a6300.
