Just a comment on a week or so back. I use the 70/200 and the 200/400 Nikkors and my friend came along to the motor race with his D300 and Sigma 50/500 which he had bought a week earlier. His autofocus broke after precisely one hour. I looked at the lens and tried it on my D2X to see if it was his cameraand no, it was the lens. What also astounded me though was the poor light quality through the viewfinder using this lens. So dark. I lent him my old 80/200 which I have had 10 years and he never missed a shot. It's put me off the thought of ever buying a seconday lens; Nikkors for me!

You are not comparing apples with apples here. The Sigma is a consumer lens and the Nikon's are G (pro quality). You are talking about f2.8 and f4 lenses and the Sigma is f4 when wide down to f6.3 at the long end. This means you are working at over 2 stops less light from the 70-200 and over 1 stop from the 200-400 so this is your reason for the loss in viewfinder brightness. As for the broken AF, I've not hear reports of many problems with this lens so seems it isa one off issue.

So basically your apples are better than the oranges in this case but if you were to have a play with the Sigma 120-300mm f2.8 for example you would find it a pleasing experience.

I'm not doubting it and have heard good reports of the 120/300 Sigma. But at the same time I have several consumer grade Nikkors and they feel better quality than the Sigma did. What I was astounded at was the darkness of the viewfinder even at the best possible setting when compared to the 70/200 for example stopped down to f22. Perhaps the fault was a one off, but it didn't inspire confidence. My oranges aren't apples as you say, but sometimes one can make false economies. My old80/200ED is worth $500 or thereabouts nowadaysand I'd rather have that with a TC than the Sigma 50/500 any day. That way, with a TC20 one has 400mm at f5.6 or with a TC17 f4 at 340mmall with the benefit oftop quality glass.

Don't forget thought that stopping down to f22 won't affect what you see in the viewfinder unless you press the dof button at which point you will get very very dark image. So you are still looking at f2.8 with the 70-200 and f4 when at 50mm on the 50-500 so that is half the amount of light.

There are certainly build differences and each company will make some good and some bad lenses so I wouldn't write off all of brand x because of one experience, however I'm not saying that buying quality lenses is not very beneficial to the end results you get.

Let's keep things in perspective here... I have no doubt the 200/400 Nikkor is good but at $5000+ you can also buy 4 other Sigmas 50/500 and replace it everytime it breaks and still come out ahead!!!
-> That is if you don't want to use their warranty which is 4 years (i.e. good for another 20 years of service at least for the same amount) to fix any problem that may arise :-):lol::-)

Sigma 50-500 @ f/6.3 handheld - I can do the same with a 200-400 too but I'll be holding twice the weight:





As to the 70-200 f/2.8 with TC - There just no way it can approach a Bigma with a 2x TC:
1. Just check its MTF on Photozone with a 2xTC against a Bigma
2. Plus the AF will slow down to limit most action shots (and it's only a 400 shy of 500mm)
