Sold my D5100, left with 35 MM 1.8G lens. What body to buy? - 1

Added (1). Requirements
1.Portraits
2.Landscape
3.Low-light

I don't need large buffers and high shutter speed.

As I have only 1 lens I can switch to a Canon too.

Added (2). Thank you FotoAce.

How about D7000 which is about 40% less costly than D7100? Does the performance difference do justice to the cost difference. I understand, with D7000, I will get the same sensor in a different body.

Added (3). Same sensor as in D5100*

I need a body with motor.(I have a 50mm 1.8D which I hardly could use on D5100)
I need weather sealing.
I need to shoot in low light

These are the reason I'm upgrading the body.
Another reason I believe this is right time to get a decent resale value for D5100.

As for buying Nikon, I learned when I started off shooting that Nikon makes better glasses than Canon.

The next step would be to buy one of the more robust Nikon D7100 or D7200 cameras

If you visit the DXOmark.com site, you can see which cameras perform best in low light.

Your current D5100 is a fine camera for shooting portraits, but you should know that, although it seems you do not have the Nikkor 50 mm f/1.8 portrait lens.

Landscapes are best shot using a camera whose sensor performs well in the areas of colour depth and dynamic range.

I use a Nikon D800e when shooting landscapes… See link below

The second link shows the sensor performances of all the Nikon and Canon cameras. What you will see is that your D5100 already shoots better in low light than ANY Canon APS-C sensors and full frame cameras have better performing sensors.

At least a D7200.

Before you leap into buying another body you have to ask yourself a few questions.
What was so bad about the D5100 that you concluded it was better to have no camera at all rather than a D5100?
You could get a 7000 series but that is just a 5000 series with a few extra bells and whistles that may or may not be of any use to you. You need to examine the specs to see if your "must have" list is fulfilled.

As for changing to Canon (or Pentax) - that too is difficult to recommend if we don't know what caused you to dump your Nikon. I have Canon but have used a friend's Nikon D5200 occasionally. My personal preference is for the Canon user interface but from an image point of view I couldn't tell the difference.

The D7000 gives you the exact same sensor as the D5100 so if you weren't keen on its performance then the D7100 is the way to go.

I work with Nikon crop sensor cameras and the D7000 is my personal favourite, the files are just the right size (16MP) and are really easy and quick to work with and move around, the D7100 performs really well too and does offer the edge in low light conditions, fhotoace is right the D7100 offers improved dynamic range over the D7000, the mentioned D7200 is worth considering for snappers that need the extra buffer performance.

I use the D7000 most (99%) of the time, and haven't ever had reason to fault its images.
