When a Nikon 80-200mm f2.8 cost about $800. Just trying to learn lens types..
Here's the lens.

Well it's a 300mm f/2.8...Huge difference. A 400mm f/2.8 will be even more expensive and a 600mm f/4 even more so...
It all comes down the the size of the lens elements needed to get such huge apertures at such a long focal length. |

This is why: f/2.8 and the glass.

If you're ever unsure of something, I'd check //www.bhphotovideo.com -- they always have only the newest stuff and pretty much the best prices...
but yeah, 300 f/2.8 is a lot more than 80-200 2.8. If you're looking for a 300 2.8, the Sigma 120-300 f/2.8 is a damn good lens and very versatile...toss on a 1.4x teleconverter, and you have a 168-420 f/4 and focus speed will be just about unaffected and image quality is great ... not bad ...or a 2x and you have a 240-600 f/5.6 and still retain autofocus (although I've never used a 2x, so I don't know how good the quality would be).

Also need to remember that the 300mm f2.8 is a prime lens, so the overall quality of the image will be AMAZING and 100% or your money back razor sharp.

| Doctornick explains it well. BH is a good place for price reference as mentioned. Personally, when I scrape up patience to order online and have it shipped (next day heheh), I check the price on BH and almost always find sigmaforles.com to be a hundred bucks cheaper. No problem with them on quality of product and they don't hassle you about returning it even if your reason is 'I don't like it'. |

I have one with my 70-200 2.8, still not much loss in quality. But, you WILL need a tripod, or at very least..a monopod.

f2.8 is what we call a "fast" lens. The faster, the better, the more expensive (unfortunately).

| It's also a VR lens. That adds to the cost. VR meaning vibration reduction of course. |

| Given that the lens weighs over 6 pound I think they are charging by the ounce :-) |
