Should i sell my nikon D7100?

i really want to make a youtube channel and i can't do that because i can't see what i'm shooting and most of the youtubers out there use the flipout screen so i'm thinking about selling it and buying canon 70D, however i know D7100 is kinda better when it comes to photos, it's pretty sharp and D7100 has better ratings, so im kinda confused! Why would i sell a 10 and buy a 9.5 -_- do you guys think it's stupid to sell a cam bcuz it's screen is not flipout?

Achieving Off-Center Focus with Canon 6D Focus Points?

Attached is one of the photos taken by loyanzi from Flickr.
I am on the way to get Canon full frame system this year.
I was considering the 50mm f1.2L and 135mm f2 L.
Now, I do not have the budget for 5D III after 50mm f1.2L, but then again, that creamy bokeh is just astounding from the 50L.
I have also considered a Nikkor manual AIS 50mm f1.2, but the bokeh is a "little" harsh, just a little.
So, I was thinking about 6D either. Later, after a few years upgrade to Mark IV maybe.
Maybe you get used to the 11 point focus in 6D, but how did loyanzi achieve these focus? I know the focus points layout from 6D.
Are these the far left /right focus point mostly, or, did loyanzi use manual focus override?
Or maybe just crop it down?
What about focusing "on the eye"? What would I do with a Canon 6D?
I have heard NOT So FAVOURABLE things about "focus and recompose".
*I have asked loyanzi. I haven't got a REPLY yet. I just want your opinion. I'm deciding between lenses. Thank you!

Can the nikon l820 change the format of the picture it takes?

I have a nikon l820 and I have noticed that the quality of jpg picture files are not very appealing. It gives my pictures a very bad pixel grainy effect and I was wondering if the format can be changed from jpg to raw? Help!

Is it worth it to get the Canon 70d?

I have $1200 to spend on my first DSLR. I know a lot about photography and getting a 70d or complicated camera wouldn't overwhelm me. Is it worth it to spend it all right now on the 70d with the kit lens, or go down a step to the t5i or Nikon d5300 and use the rest for lenses and flashes. With the 70d I would be able to get another 50mm or 35mm lens around Christmas time, but I wouldn't be able to get another lens until next summer. What should I get? Is it worth it to get the nicer body but not have as good of lenses for a little while? Or would you get the less nice body with a nicer lens or two?

Problems with photographing star trails?

So today I decided to try and shoot a star trail. I have a nikon d3200 with an 18-55 kit lens and I used an shutter release timer remote. I did 60 1 minute exposure with one second in between exposures. I think that is where I went wrong, with the interval timing. I stacked all my images together using StarStax, and the trails came out as dotted lines versus solid lines. Is there a way to fix this?

here's another example very similar to what happened to my photo ( I don't own this photo)

and this is the type of star trail I want:


- see how this one right above has fluid, solid trails versus the first one? That's what I'm confused about

Looking for a reasonably priced fair quality camera?

I wish to start dabbling in the art of photography, because it pertains to the future career I am looking to engage in. The camera does not need to shoot video if it doesn't have the ability. I wish to see a reasonable price tag and some decency that could last me some years of use. Simpler controls would probably be better, since I am only learning, unless you suggest otherwise. Any experienced photographers out there who could begin pointing me in the right direction would be greatly appreciated.
Thank you for the feedback in advance,
-Lu
