Hi adw!

I am using the sigma 170-500mm DG with my Nikon D50 and the Nikon D70s and I am more than satisfied.
I would love to own a Nikon lens you mentioned, but the budget......... :roll:
At the moment I am at work, but as soon as I get home tomorrow afternoon, I will send you some samples of pics that I have taken with the Sigma /Nikon combo.

me thinks it's because it's a DX lens and not as the dealer tells you as the the 18-200 is an AF-S lens :D

My 2c worth:-
From what I have read on other forums the Sigma APO 50-500mm F4-6.3 EX DG HSM lens seemed to be the one forum members prefer than the 170-500. The price difference is R1600. I am also in the market for a "long" lens so have been doing some reading but no decisions yet.
It will be interesting to hear comments on the 2 lenses

If I am not mistaken, there is also a Sigma 50 - 500 lens.

I also have a D50, and pondering the idea of upgrading as I only have a 300mm Nikor lens, and cannot afford the 500mm Nikor lens (who can?).

Not being a professional photographer, will it be better to get a lens or simply use a 2x converter.

I have heard a lens is much better, but will the converter have such a great difference in quality.

hi JV, before buying a 2x converter take your lens to the dealer. I recently found out that the Nikon converter does not fit all Nikon lenses. (see the various comments under my topic Nikon 18-200ml lens).

Here are some samples of results I get with my Sigma 170-500 mm DG in combination with either the Nikon D50 or Nikon D70s.
Just have a look at the EXIF informations.Most of the pics are taken with this lens.
The Sigma 50-500 mm is a very nice lens as well.
Maybe you got the chance to test them with your cam.

Thanks Katy. I think your pictures were super. That more or less settles it. At the price I have been quoted I will now purchase the Sigma lens which is less than one tenth of a Nikon lens.

Thanks for the info.
But now I am confused. :hmz: The lens is called "18-200mm f/3.5-5.6G IF-ED AF-S VR DX". So it is an AF-S lens.
Or are we not talking about the same lens?

The issue is the fact that is a DX format lens .. designed for Nikons DX format sensor as opposed to full 35mm cover ... the AF-S designates the lens has Silent Wave Motor built into the lens ... a TC can be used on certain lenses that are both AF-S and AF lenses

Sigma 500mm lens

Unread postby wmahon465 » Mon Dec 17, 2007 3:14 pm

I have the 50-500mm sigma, I get good results but a word of caution, this lens is heavy, you will not easily hand hold so a monopod or long beanbag will be needed. The lens does have a tripod collar but if you do use a quick release mount, make sure it is capable of being locked as the weight could pull it out of the mount.

I can second that for the 170-500 mm lens as well.
With 1,345g it's a bit less heavy than the 50-500 mm (1,840g), but I recommend a beanbag as well.
Have a look here for the facts about the 50-500mm and here for the 170-500 mm.

The sigma 50-500 is by far superior to the 170-500 .

Only a few people are happy with there 170-500's and by far the bad copy's outweigh the good ones .
I had a bad copy and I have very few decent pics taken with it .
I was ready to throw it away .

I would pay the bit extra in and get the far newer , optically superior and greater zoom of the 50-500

The fact that you cannot use a Nikon TC has nothing to do with it being DX and AF-S. You can use the TCs with both Silent Wave and screw drive lenses, DX and full frame.

The problem is that at 200mm the 18-200 is simply too slow. Hence the Nikon TC intentionally does not fit. You need something with a speed of F/4 or faster. Think AF-S 300 f/4 or 70-200 f/2.8.

However, the Kenko Plus 300 1.4x and 2x converters do fit and work; well sort of. The focussing is now so slow that it is unusable.

Rather look at the new 70-300VR or a used AF-S 300 f/4.

The 170-500 is a lens that you buy, use for six months and then sell to get a 50-500 or a Nikon lens. It is OK for static items but is way too slow for BIF or any action shots. See how many come up for sale on www.outdoorphoto.co.za

Rather get it right and buy a used 50-500 or Nikkor AF-S 300 with a TC for the same money.

PS: You did not mention what camera you have. Remember the 170-500 will not autofocus with the D40 and D40x as it does not have HSM.
