What filter is needed to photograph the sun?

If you want to photograph the sun, what filter would be needed and while asking, how much lens focal length would I need?

I'm wondering if I need top buy one of those smaller telescopes for this?

You don't want to photograph the sun directly, and the longer lens you would use, the more dangerous for you and your camera's sensor......
From Photo.net....

The Sun - The sun, when in a clear sky and anywhere but a few degrees above the horizon can easily damage your camera/lens, and more importantly your eyes, if you look at it for long enough. You need a filter, and if you intend to look through it as well as photograph through it, it must be a filter designed for visual use. Some filters block visible light but pass IR. Exposed film is an example of one such filter. Unless you are an idiot, intent on becoming a one-eyed idiot, don't use anything but a properly designed visual filter to look at the sun! Check out any issue of "Astronomy" or "Sky and Telescope" magazine for suppliers of solar filters for visual use. You can also check this link to a NASA site  for a list of solar filter suppliers. With any lens or telescope used to observe the sun, the filter goes on the FRONT of the optics. This is very important. Stick a 5ND or 6ND filter in the slot at the back of your 600/4 and point it at the sun and you will soon be very sorry indeed that you did. Al the light and heat will be concentrated on the filter and it will crack, possibly damaging your lens, camera and you. Even if it doesn't crack there is still a good chance you will damage some of the smaller internal lens elements due to heating. Exposure depends on the exact filter you use, but you should aim for something in the 1/250 and faster range to avoid problems with camera/lens shake when using a really long lens.

Why so serious?

To photograph this:  www.eclipse2017.org/2017/path_through_the_US.htm  

will be a big deal next year.  You might want to get set up with a entry level scope and they have a range of filters for photographing the sun:  www.amazon.com/s/?ie=UTF8&keywords=celes...f=pd_sl_78froy5zyc_b

How many stops do you need to photograph the sun?

You can pick up a scope for $700 to $900 that will get you super close to the sun.  FYI

This one was taken with a 40-mm Coronado Personal Solar Telescope using a hydrogen-alpha (Hα) filter.  (not my shot)

Yes, this is going to be a spectatorial event.  Everyone in North America should be able to experience this.

How come the kids photo of the sun is B&W?  How do you get the orange that you see in so many photos?

Crazyguy it is a matter of which filter they used that they get certain coloration, or lack thereof.
To the OP, and anyone interested, here are the best filters  thousandoaksoptical.com/solar.html I prefer the glass filters for durability. What you will get as for details on the sun is black spots. Tehese filters are for getting your feet wet into it. To get any of the prominence details such as flares, you have to go to a whole other level, and hence more cost. It takes a filter set that do many things to see that. Those Corona scopes are really a bargain, and you can get adapters to mount you camera to them.
