If I bought Nikon D5200. Is the strap included?

Is the strap included? I'm buying it from ebay. I'm not sure if there's a strap or do i need to buy it separately? And can you tell me must have accessories for DSLR D5200 Nikon? Forget the lenses though.

If you were buying new yes but used… Difficult to say because that's up to the seller.

Another thing, be very careful buying through ebay. It's become a dumping ground for every scam out there.
Lots of horror stories about gear received that doesn't work and other problems.

Strap is included. If buying from ebay, mileage may vary. If the price is too good for a new camera, then you may be getting grey market equipment where the warranty isn't valid in the US or some other scam.
Check prices against a trusted store like B&H Photo or Adorama.

Not the best presented question i've came across…

You don't mention if this camera is listed as new or used…

If the camera is new then it should be supplied with the instruction manual, battery and strap… It's a good idea to consider buying a spare battery as a back up and you will need to get yourself a couple of SD memory cards, if you shoot video then you'll need memory cards that are above class 6, class 10 are recommended for video… A couple of 4GB or 8GB cards are better than investing in one large card… Cards over time can become corrupted and this can cause you to lose shots that are on the damaged card.

Here is a listing of a Nikon D5200 body with BH Photo, showing the section "In the box"

That shows what Nikon normally includes.

The items under "Included free" are added by BH Photo, and they would be in the shipping box, but not within the Nikon box.

Even if it doesn't come with a strap, a suitable strap will cost next to nothing from any reputable camera store.

Other than a battery, lens and a memory card, you don't need anything to start shooting other than commitment.

If it is new in the box it will come with a so so quality neck strap. I prefer a lightly padded one myself that doesn't advertise what kind of camera I have.
