    Great camera for enthusiasts to professionals

    This camera is great for all occasions. If you're new to photography you can set it to auto and it will do all the work for you, and the more experienced you get the more options there are to take your photography game to the next level. We loved it for portraits, landscape and food videography!

    Great little camera.

    Thiis is a great little (literally) camera much smaller and lighter than my Canon EOS 5 Mk II. I have been using Canon gear for many years now, and the adapter which comes with the body allows me to use all my current lenses. My only problem is to do with my ageing fingers. When I'm prowling with the camera/lens etc I inadvertently keep pressing the Movie button. Of course these images can be removed after downloading. The movie button works well when needed, producing a very nice product.

    Superb Camera

    Small body big on performance. Great for field work as it is lighweight AND packs sophisticated power and reatures of DSLRs. APS-C CCD produces crisp and beautiful images of portraiture thru to landscapes. Versatile touch screen allows access to all camera settings and configurations very quickly and without fuss, or extensive study of manuals. This feature alone makes it a breeze to massively improve your abilities to utilise camera config options to capture better images! Smartphone pairing allows wireless remote control shutter release! This is super cool - it literally turns your phone into your camera! Candid street photography is a reality now as no-one knows you are shooting. Imagine how much better, more natural and relaxed people are, when they dont know you are shooting! This is stealth-mode photography made easy. Fast wireless download shots to your phone for viewing and post production editing. No more clunky cables... yay!
