I purchased the J3 to replace a P&S I had that got the LCD ruined. The J3 takes great photos for the most part. There can be quite a bit of grain at higher ISOs, and sometimes the results are muddy in low-light situations, no matter how you tweak the settings (I've noticed this mostly in sunrise/sunset photos where flash is not used.) My main complaint is that the bulb function is unusable. There is no radio/optical remote function. The only option for a remote is the WU-1b wireless adapter. While this gets you connected to a smart phone or tablet pretty reliably (at least it does for me), the WMUA software completely ignores any settings you made in the camera and goes pretty much full auto. It even ignores the camera being set for manual focus. What this means for the bulb setting is that there is no remote. Once you tap the picture button in WMUA, it takes the picture at the shutter speed it has determined, and you have no control over when the shutter closes again. I knew the basic limits of the camera when I purchased it - no hot shoe for off-camera flash, limited number of lenses, no exterior controls for some of the important bits, etc - but I did expect the features that were there to be usable. Bulb mode is not usable if you have to hold the button down to get an exposure longer than 30sec and introduce a substantial amount of camera shake. Also, I don't understand why pressing the right side of the circle control doesn't let you go over to ISO in addition to shutter and aperture rather than having to dig through a menu. Seeing as how those three controls are the most important ones for controlling exposure, it seems like that would be an easy enough bit of firmware to implement. Just about everything else I set and forget so going into a menu every once in a while to adjust it isn't a big deal, but frequently and repeatedly going into a menu to find the right ISO setting for the situation is kind of a hassle. So, I do recommend this camera overall, I love taking pictures with it, but there are some caveats as to its overall functionality.
