Let me start by saying that I purchased this camera mainly to capture photos of our 10 month old baby son. As we all know infants move unpriedictevly and fast focusing camera is a must. Here is why this camera delivers on that task.1. It’s fast. I mean lightning fast not only in acquiring focus but also during handling like switching between menu, playback and picture taking modes. I never wait for things to happen, I press and it happens.2. Burst mode is incredibly fast. It’s critical to have fast frame burst mode in order to capture that baby’s smily face. 24 frames with continuous focus is crazy fast!3. Touch screen! Finally Sony!Even though it only works during live view mode to pin point autofocus and during playback mode to magnify picture(no pinch to zoom in or out unfortunately) I don’t think I’m missing out here. I don’t use touch screen in menus anyway. I works good, I don’t feel any lags.4. It’s very customizable in terms of assigning shortcut buttons.Sony’s menu is not very intuitive especially coming from Canon world but I think once you setup my menu items and reassign buttons the way you like you will be OK.Particularly I like one feature. It’s burst photos images grouping.If I take burst photo with let say 50 photos I don’t have to scroll trough them all to get to the next picture, camera groups those 50 photos in 1 group and you can exit it and go to next picture. Another neat feature is that you can protect picture you like and delete the rest of pictures with press of a button, so you have to delete 49 other pictures manually if you like just 1 of them. I don’t know why other cameras don’t have that, it makes my life much easier.5. Great dynamic range right out camera’s JPEGs.We all probably had a situation when you want to take a photo from inside restaurant with some beautiful view outside and people by your table but than you have dilemma. When background is properly bright people by a table are dark, if you want people on your pic to look bright background becomes overexposed or very bright. That’s when this cameras outperforms any other cameras I have used. It has feature called DRO it makes dark areas brighter while keeping whole scene properly exposed. It’s not HDR function when camera takes 3 photos and stacks them, it only takes 1 photo. By the way it has HDR mode too and works well too but as we all know it’s only good for still scene as photo can come out blurry if anybody moved during capturing these 3 photos.6. You can take 4K video and grab photo from it. I love this function, I just shoot high resolution 4K video of our constantly moving baby boy and then just grab 17 megapixel frame from it if I like it. Great feature!7. You can instantly transfer photos to your smartphone via WiFi no cables needed even when you are outside away from Wifi.It’s not as simple setup as Canons system but it’s easy enough.And you can start sharing those photo minute after you took them!Overall I’m very happy with my purchase. Lack of touch screen held me back from buying rx100 cameras for years! Not anymore!Yes this camera is expensive but it’s good investment that will last.I don’t think I will need to but any other camera for many more years.It does everything I need it to do superbly!
