Should i switch from a nikon d3100 to a d2h?

These days i'm only working on black and white film photography for school and i never find myself using my dslr. I used to have a d2h a few years back and i loved it, i had loads of fun with it. Realistically, would it be smart for me to sell off my d3100 for a d2h?

Memory cards for Nikon D700?

Just wanting to know what memory cards are good for Nikon D700, and should they be 16 or 32's? I will be using them for wildlife, portraits and weddings. I don't want to spend hundreds on one.

Zykkor super wider semi fish-eye 0.42x fit?

It won't fit on our Nikon D300 lens which is AF-S NIKKOR 18-55mm 1:305-5.6G. We also have one old lens, Nikon LENS SERIES E 50mm 1:1.8 and we have another old lens which we know will not fit because it is a convex type of lens (Nikon LENS SERIES E 135mm 1:28)

Opteka.35 fisheye very blurry?

I'm using it on a Nikon D4 (Full frame), to which it should be compatible. I attached it to my 50mm 1.4 lens. (Which in FF should be like a 35mm on a crop camera). I have tried switching to manual focus and the view is COMPLETELY blurry. (Not just bad quality blurry, but 100% blur). What am I doing wrong? The macro attachment works fine.

Added (1). Thanks for all your responses. Yes, I was also thinking that maybe my 50mm wasn't wide enough. I'm planning on getting a 35mm in the next couple months, so will try again on that. In the meantime, the macro works great. And yes, I know this isn't a lens, it's an attachment with shoddy glass on a gorgeous 50mm 1.4G lens coupled with a $6, 000 camera. I wanted it for fun to take some interesting pics of my kids. I wouldn't be using the fisheye for professional use unless I had an actual fisheye lens (a little outside my budget right now, since I'm eyeing that new Sigma 35mm 1.4). But it's on my "win the lotto" list.
I trying closing up my ap, but that didn't help. At least the macro works, so I may not return it.
I just jumped the Canon ship for Nikon, so trying to build up my lens arsenal again, just can't afford a "real" fisheye yet.

Added (2). Wow, didn't think I would get such a hostile answer to a simple question.
As mentioned previously, this was just a fun accessory to get some interesting pictures of my kids during off hours. In fact, I know several professional photog friends who own D4s and D3's and use macro tubes and adaptors and fisheye adaptors for fun. They were the ones who recommended this item to me. I don't think there's ANYTHING wrong with putting a cheap fisheye adaptor on a $6, 000 camera as long as one understands it will not be of the same quality as the lens itself (or an actual fisheye lens). And secondly, that one does not use it professionally, charging clients for images that are of much less quality that what they expect.

Looking to buy a great camera/video recorder?

So I'm a beginner photographer and a filmer. My friends and I like to go and film movies; scary, comedic, ect. So I'm wondering if there's a camera 16 mp (least 14mp) out there along with HD video recording (1080) for video recording? I was deciding on the Nikon D5100 and then learned about the Nikon D700… Anyway! I'm looking for a camera with those two important qualites in the price range of $100- $600 Max.
