View Full Version : Which 18-200mm Zoom for D70?

I am about to buy a 18-200mm zoom for my D70, just to add 'single lens' flexibility when I can't take both my Nikkor 18-70mm, and 70-300mm. Here in Australia, the Tamron is being heavily promoted, and now offered as the new D70s 'kit lens'. But I have heard that the Sigma is a better lens (though in practice, not quite as 'big' a zoom range as the Tamron. One review suggested the Sigma is really probably only a 19-190mm)

Does anyone have any experience to offer? I am leaning towards the Sigma. Is there anything nasty about this lens? It seems to be slightly lower-priced here in Australia. Appreciate any helpful feedback from experience

If you have read the one test from Japan and some posted here the Sigma seems to come out the winner. If you get a beter picture at 19-190 than the Tamron gets at 18-200 then that should be the concern.

I shoot the 18-200's little brother (18-125) and it has turned out to be a very good day-to-day lens, and I am still seriously considering the Sigma 18-200.

Well, me and some of my friends just discovered something about the Sigma, the 18-200 is NOT a 200, maybe just 170 or so. Here's an example : 2 shots, one with the sigma 18-200, the other with the sigma 70-200, both taken at 200 mm.....no further explanation needed I guess, there's a big difference. I like the quality of the lens and the pictures but this lens is definately not a 200 mm lens.

You may want to wait a little. Rumors are Nikon is releasing an 18-200 AF-S VR soon. If it's near the quality of their 28-200 with AF-S speed, a wider bottom end & VR it will be a winner.

Where did you hear that? If true, then definately worth waiting for.

This is interesting...surprised that (1) no one has commented on it yet and (2) no one here has done a similar test. I can't setup this test as I only have the 18-200dc. But I did write Sigma after reading this post asking them to speak to this discrepency. If you are correct, this is definitely false advertisement and thousands are falling prey to it (including me!).

So, we'll see how they respond. I'd love to hear from anyone else that might have an explanation. The only thing I could think of is that the test was faulty and the camera was moved.

Anyway, very interesting. I have loved my 18-200DC with my D50...and this post doesn't change that. Depending on the price of the possible new Nikon lens it would seem the obvious choice. But if you want it now and/or if the NIkon price comes out too high, I have had great results with my 18-200...highly recommend it.

I'd be very interested to see a test that includes the Nikon 70-200mm, as a reference, to see how both Sigmas - the 18-200mm and the 70-200mm - measure up. At this point, I'm inclined to be somewhat skeptical. The Internet can be a rumour mill/hoax harborer :cool:

Not sure if you saw these spy photos yet, but The guy that claims to have taken them has been a pretty reliable source for inside info (he posts at DPreview) He said the prototype (pictured) of the D200 had an 18-200 AF-S VR

I looked at the IEXif data in Opanda.
The first image was taken on October 2 at 15.01.52 with a lens type "Nikon D Series lens" at 200mm.
The second image was taken on October 2 at 15.00.41 with a lens type "2" at 200mm.
So what gives. Does Opanda report Sigma lens' as Nikons or am I missing something?

Thanks.

Kind-of a double whamy... bank account wise. Did he hint at the rumored price? The 24-120 runs around $500. Hopefully this one won't be too much more.;)

No word on price but They'll have to keep it fairly reasonable I would assume as this sort of lens is aimed more at consumer/enthusiast crowd than the pros. I'm really looking forward to it. I had the 28-200G and loved it (I sold it with my D70 when I bought the D2Hs) and have since really wanted to get my hands on another 28-200- but I've forced myself to wait and see what the new lens brings.

If image quality is on par with the 28-200 I will be able to get rid of a few mid range zooms (18-70, 24-85, 24-120vr) I use for different things and finally have the walk aorund lens I've always wanted. . . time will tell.

I used a tripod to make those pictures ;)

Hey all,
I was so interested in this one that I emailed Sigma about it. Here's it their reply:


Dear Michael

Thank you for your inquiry. Evidently, you (and others) are not familiar with how lenses are described, nor how they focus to different distances (especially inner focus lenses), and how they perform. A lens’ focal length and aperture are described when the lens is focused on infinity, because these characteristics will change as the lens is focused to different distances. By convention, most manufacturers adhere to a +/-5% tolerance for these characteristics. An ordinary lens’ focal length can become greater as the lens is focused to closer distance. It also becomes physically longer. The focal length of an inner focus type lens becomes shorter, as it focuses to closer distances. But, its physical length remains constant. The amount of change can vary depending on the type of lens, the lens’ maximum focal length (at infinity), etc. The posted comparison test images were obviously not made with the lens focused to infinity, therefore this shortening effect of inner focus is evident in the image made by Sigma 18-200mm compact zoom. When Popular Photography magazine reviewed the Sigma18-200mm DC lens (August 2005 issue), they measured the focal length (at infinity) to be 205.24mm. Popular Photography is long-established, well respected “brick and mortar” photographic publication, whose staff is accustomed to objectively and scientifically testing and evaluating photographic equipment. We do not believe this constitutes misrepresentation or false advertising, but thank you for your support. {FYI the maximum focal length of the Tamron 18-200mm XR Di II (July 2005 issue) was measured to be 196.10mm. Fancy that.} Things aren’t always as they seem are they? As Kenyada posted, ”The internet can be a rumor mill/hoax harborer.”

We hope this information is helpful to you.

Sincerely

SCA

Pretty interesting, and singularly addressed, reply. How long did it take to get that answer? If it was less than a week it at least shows someone is reading the e-mail, and responding with quite a bit of information. I guess kudos for Sigma Customer Assistance.
