Nikon J1 sensor not letting in light?

I've had my nikon j1 for awhile and i had to get a new 10-30 mm lens. The new 10-30mm lens broke so I had to get another but the lens doesn't seem to be able to take in all of the light. When i take off the lens the body is able to get in more light. I have tried with the 30-55mm lens and that one lets in enough light. I have also tried reseting the camera to factory settings. Anyone have any idea as to why the 10-30mm lens for my J1 isn't letting in enough light?

I've heard due to the recoil & vibration etc, alot of lower end scopes are not fit to be put on a rifle of this stature. I've heard about the vortex viper and a model by nikon called the 6100 Elite? Forgot the name. But I'm just curious, but uninformed and led in circlea of trying to research and find other options on the web. Nightforce is an option yes, but only if I have 3500 haha. Any suggestions, please?

Is an iPhone 6 plus camera good for filming?

I know this is a dumb question since I'm considering buying a phone for a camera, but help me out if you guys can since I don't know my facts too well. I'm a film maker, and for awhile I've been using a Samsung WB250F, but started to look back the quality just isn't as great anymore, I just doesn't have as high quality as i hope and looks pretty bad on retina screens. I've been trying to buy a new camera, and recently stumbled on an iPhone 6 Plus, that has a beautiful quality camera, and I do love the 60 frames per second recording, but is that a good idea? I've also been looking at Parasonic Cameras and Nikon Cameras, but I'm just not sure what to spend my money on, and which could offer my needs? Also, I saw an action cam by AEE, that has 4K recording and 60 FPS. Is that a good option too since it has high specs. Only thing that makes me skeptic about it is that it's only $250 which is really cheap and it's a go pro type device.

Playback display options on Nikon d5200?

In the playback menu on my 5200 there's playback display options. I wanted to use highlights and I have used them before but turned them off. Now I want them on again and I know how to turn them on you check the box just as you would for any of the options then click ok. My problem is that it never actually works. At first I though maybe I just don't have any highlights so I tried overview and histogram and everything else and nothing shows up after I take a picture and I can't figure out why. If anyone knows how to fix this it would be great.
