You should probably indicate your budget, whether you prefer primes over zooms, how fast you want your lenses to be, whether you want AF and other automation features, etc.

The longest modern lens, I can think of, of the top of my head would be the BIGMA (Sigma 50-500mm). Would that one be too heavy and expensive?

Do you have the kit lens (18-55)? If so, do you not like it for general use and why not?

Answers to the above questions would help to assist you with your search.

regardless budget:
Sigma 50-500 has quite a strong following, but have a look at DA*200 or 300 with 1.4 or 1.5 TC. They a regarded as very good lenses.
For general use, kit is not bad, if you want to upgrade it, Tamron 28-75 has quite a reputation, but could be better built, there is new DA17-70, or Sigmas 24-70, 24-60.

Welcome to the family! My recommendation is the Pentax or Tamron 18-250. It is a very versatile lens, and will work well for your application. As you learn more, you might like to get a longer (but more expensive) "birding" lens. I think the 18-250 is a good start.

I INTEND TO BUY ONE LENS FOR BIRDS AND LONG SHOTS,
this is a tricky subject, and we can all give advise on how to spend well in excess of $6000 US or as little as $500 US. but as a good reference, I would suggest you look into a 70-200 F2.8 and a couple of high quiality Tele Converters, since this will be the most useable overall, or to go for one of the sigma zooms that reaches out to between 400 and 500 mm, but you will give up F2.8 for the 70-200 range

there are more general use lenses than you can count, but look at anything that gives F2.8 across the focal length range you want. Sigma tameron and pentax all make fine lenses in teh range of 16-28 mm at the wide end to 50-80mm at the long end.

it is all as simple as going out and spending money.

If you are seriously intending to photograph birds, 300mm will be very short to do so. You need a good tele converter to get a focal length more useful, like a 1.4x tc, which brings you up to 420mm , though you also end up at a maximum aperture of f/5.6, instead of the lens' f/4. I would therefor considering a good long tele zoom, which gives you more reach and more versatility, though even the Bigma is still half an f-stop slower at the long end. What you should also take into account (literally) is a good tripod, as these focal lengthes really afford a stable platform.

If you are after a budget solution, I would recommend the 55-300. Seems to be a fine lens for the money.

Regarding the Tamron/Pentax 18-250, I own it and like it a lot, but I wouldn't recommend it for birding. It is rather slow at 250 (f/6.3) and you want to stop it down to ~f/8 for better IQ. The 55-300 will give you more reach, more than the nominal +50mm because the 18-250 only approaches true 250 when focused to infinity.

Regarding teleconverters, I suggest to not exceed x 1.7. The IQ of many 2x converters suggests that you may be better off with just cropping the image. Make sure you get a converter which supports the automation you are after. Not every converter supports the electrical contacts for A lenses, for example.

as I said in the intiial response, we can suggest anyting from 500 to 8000 for birding

So, just how serious a birding lens do you want.

For me, and I have been at this a while, I have never intentionally gone birding with a lens smaller than 77mm front element.

That is F2.8 at 200mm, F4 at 300mm and F5.6 at 400mm, and is why I suggested a 70-200 F2.8 zoom as the base lens. That lens and a couple of good TCs will be much more useable than either the BIGMA or any other of sigmas long tele's.

While some people, including myself have posted excellent shots with lesser lenses, including some bird shots at about 17mm, these are the exception.

A 50-300 F5.6 zoom, might leave you disappointed,

Maybe some of the existing owners can speak up and tell what they think of a lens like that, in moderate lighting conditions,

You might also want to consider the used market, as there are some bargins out there,

That was a big investment you have made and your choices look pretty good to me. Enjoy your new equipment and go out chasing birds!
