BriefThe QX100 is a very portable camera to be used in conjunction with your smartphone, it has a large 1" sensor and a Carl Zeiss F1.8 lens which delivers high quality photos to your smartphone; this allows you to share quality photos that you wouldn't get from your smartphone to sites such as Facebook or Instagram on the go.Box Contents & Optional PurchasesInside the box: QX100 Camera | Smartphone Attachment | Micro USB lead | Battery | Wrist Strap | Instructions & Documents.I never expect a case to come with cameras, but for a product such as this, I believe it should have come with something, even if it was just a little carry pouch to help keep it that little bit safer...Optional: MicroSDHC Memory Card* |Spare Battery (NP-BN1)|Carrying Case (LCS-BBL).*You only need a memory card if you wish to save the full resolution photo to the camera, if you don't have one inserted, it will just save the photo at a lower resolution (2MP) to the connected phone.Set-UpThe first and most important thing you need to do is install the "PlayMemories Mobile" App which is located within the 'Play Store'/'App Store', without this you wont be able to use the QX100 to it's "full" potential.Next, if you're wanting to attach the QX100 to your smartphone, you will need to grab the smartphone attachment and equip it onto the QX100, though if you're connecting it via NFC, follow the NFC steps before fully attaching it onto your smartphone. Alternatively, you can put the QX100 onto a tripod or you can simply hold it.Once done, follow one of these steps:Smartphones with the NFC feature:1.Turn on the QX100.2.Touch the QX100's NFC hotspot (top of device) with your smartphones NFC hotspot (normally located on the back) and keep both touched until the PlayMemories App loads up which will then connect both devices together.Manually connecting with Android:1.Turn on the QX100. 2.Load up the PlayMemories App. 3.Select the DSC-QX100 and type in the password which is located inside the battery cover (should remember the password for future use).Manually connect with an iPhone:1.Turn on the QX100.2.Select [Settings] followed by [Wi-Fi].3.Select the DSC-QX100 and type in the password which is located inside the battery cover (should remember the password for future use).4.Confirm the devices connection.5.Go back to the home screen and start-up "PlayMemories Mobile".#NOTE: I've been using this product with my Sony Xperia T (Android smartphone).Using the QX100 with no AppI didn't think this was going to be possible, but it certainly is! As long as the QX100 has it's own memory card, you can snap up photos by simply pressing it's own shutter button.The only downside is you can't see what the camera is seeing, so you have to guess. Also another I need to mention is that the QX100 will be using the last settings you had selected when using it with the app, so if manual-focus was last used, you may get out of focused photos, so if you're planning to use the QX100 this way, make sure you have the autofocus.Using the QX100 via the PlayMemory Mobile AppUsing the App was fairly simple to navigate around as there isn't too much on the screen and I found it rather easy to use.You have a choice of four different photo modes: Intelligent Auto*| Superior Auto*| Program Auto**| Aperture Priority Shooting***.* These are automatic modes, which seem to do a fantastic job.** Aperture is automatically set, but you can adjust the exposure.*** You can manually adjust the aperture & exposure.The settings icon will give you access to the following options: Self-Timer (Off, 2sec or 10sec) | Focus Mode (AF-S or MF) |Still Image Size*| Review Image (On, 2sec & Off) | Save Options (On or Off)**| Size of Review Image (2M or Original) | Beep of Connected Device (Shutter, On or Off) | Format***.* Options are for the QX100 only, phone images will be saved at 2M: "3:2 20M", "3:2 5M", "16:9 17M", "16:9 4.4M", "4:3 18M", "4:3 5M", "1:1 13M" & "1:1 3.7M".** If "Off" is selected, this will stop the QX100 from saving images to your smartphone.*** This will format the QX100's memory card (note if anything is on there, they will be deleted.Other commands on the app will let you zoom in/out, take a photo, select movie mode or view your images (which will close PlayMemories down).Alternatively, you can zoom in/out or take a photo using the buttons on the QX100.Camera & Image QualityThe camera feels absolutely solid, not one part of it feels poorly made, so you really do get the sense of a high quality product.When shooting photos, the QX100 is able to focus on subjects really quickly as well as precisely, it also delivers superb depth of field and is able to cope well in low-lighting conditions which brings a very happy tear to my eye.Pro's & Con'sAfter using this product for several days, I do have a mix bag of feelings with this product, I personally think it's a really cool and unique product, but it's nowhere near a flawless product and certainly needs improvements which I hope will be implemented in future software updates.Pro's:+ Easy to use (exterior & software).+Lightweight & portable (not pocket portable, but will fit in small bags).+ Great in low-light. + Superb depth of field.+ Fast autofocus. + Easy to use manual-focus.+ Quality photo results.+ Separate lens from phone, which allows for more manoeuvrability.+ Make's it easier to share photos on the go.Con's:- App can lag from time to time.- App sometimes stops responding.- No burst mode.- Lack of modes & customisability, shame to see no shutter priority!- No option to display grid.- Starting camera up isn't as quick as other digital cameras.- No option to activate the phones flash. - No RAW support (though this doesn't personally bother me).I'm sure with more use I'll find further pro's and con's about this camera (hopefully more pro's than con's), which I will certainly update when this occurs.Final OpinionThere are quite a few software issues which really need sorting out as this is the cameras main downfall, so fingers crossed Sony can pull something out of the bag in the near future.However putting the negatives aside, I still really love using this product for many reasons; ease of use, portability and of course great quality photos that I can then share on the go!Would I recommend this to people? Yes I would, though I would simply say keep an open mind about the product. Although it's as costly as some advanced cameras on the market and to what I've seen the quality is comparable to Sony's RX100M2, however... it just doesn't have that manual control other cameras have to offer, so bare that in mind and try not to expect too much from this little device.
