Ken Rockwell has an excellent lens comparability chart. ( http://www.kenrockwell.com/nikon/compatibility-lens.htm ) The Nikon 3100 series has some restrictions but most modern lenses work. It is a DX format camera. Consider sending Ken a couple bucks.

Buy both. Filters provide lens protection. When macros are taken it is possible to shove the lens into a bush or rock. Hoods are great for most shots. For macros they can get in the way, however.

I have used NX-D with no problems. Computer is Win 10 and i-7 processor. It works fine on Win 8.1 laptop with i5 as well.

I have used both methods and they both work. Just be sure to tighten the center pole. A piece of cloth ( e.g. jacket, sweater etc.) can be helpful in keeping scratches of the camera.

Before you make a decision consider the type of photography that you do. The 18-55mm is not so bad and I can say 75% of my photos could be done with this lens. I like super wide and macro lenses. The 55-300mm lens is not so bad as it is fairly light weight. The alternative to this is the FX 70-300mm (faster focus) as for the wide side the 18-55, 16-80 (f2.8-4), 16-85 and the 18-140mm are good choices. I rarely go into a photo situation where I can't choose the general focal length range that I want.

I has a good experience selling some high end equipment to Adorama. They claimed that they gave 70% of what they can sell the stuff for.
I suspect B&H and KEH are OK too. Adorama pays the postage both ways if you do not agree to the price. If you sell on e-bay remember that both e-bay and paypal take a chunk.

Personally, I like photos to have whatever aspect ratio that is photo appropriate. I want the entire edited photo. Some printers will print the entire image. Indeed there will be some blank space but so what. A alternative is to place the photo on top of a constant color layer with the right aspect ratio. ( white, black, gray or other color)

The choice is a bit personal. I have three prime lenses for my Nikon dx. They are 35mm f 1.8 , 50 mm f2.8 macro and 85 mm f3.5 macro. I like macros so this explains the choice. If I had another prime lens it would be around 16-18 mm. All of the mentioned lenses can be used for different kinds of portraits. In the film days lenses in the range of 80 - 100 mm were often used. In DX format this would correspond to the 50-70mm range. In general, the 85 is a bit long. Having said that I have taken portraits with lenses from 10mm to a least 200mm.

A Nikon Coolpix 5400 not a bad point and shoot.

I have not have had any problems at all with computers, cameras or communications radios. I do have TSA pre check so bags are rarely opened. If it fits its cool. Otherwise it is Fed EX

the MC-DC2 is great. I have one. I also have an intervalometer which can serve the same purpose as the MC-DC2. This device can be used for exposures longer than 30s and can take a series of pictures at a given interval. It can also act as a self timer from 1 sec to 100 hours. Several brands ( I think most are made in the same factory) are available cost about $30.

In addition to the above one can consider a window tablet. Some have a small amount of disk space but most have a micro sd card slot. You will then have a duplicate.

Never use it.
