2x tele converter?

Hi, i was wondering if this is a good accessory to have: http://www.amazon.com/DIGITAL-OPTICS-TELE-CONVERTER-NIKON/dp/B000LTZ5UK/ref=sr_1_9?ie=UTF8&s=electronics&qid=1257133345&sr=8-9

I'm getting my d90 tomorrow with 18-105 kit lens and i was wondering if this would be a good way to increase the zoom?

In a word -- No!

It will change your 18-105 f/3.5-5.6 lens to a 36-210mm f/7-11. Theteleconverter also does not support AF so you will have to focus manually, which will be difficult because the image in the viewfinder at f/11 is not very bright.

There is a reason why Nikon’s own teleconverters won’t fit on your lens, because Nikon doesn’t think they work. I have read a number of postings by people who have tried 1.4 & 1.7x teleconverters, cost two to three times what that one does, on Nikon consumer lenses and the general consensus is that you can achieve a sharper image through cropping. Even on Nikon Pro lenses 2X teleconverters are sort of a crapshoot; 1.4x work really well; 1.7x give decent results with some extremely sharp lenses like the 300mm f/4, but most people complain about the loss of IQ with 2x teleconverters.

When it comes to telephoto lens there is no such thing as a free lunch. I shoot a lot of Hummingbirds and the 70-300mm VR lens works reasonably well, actually for the price it is great. I would love the 300mm f/4 with a 1.4x Nikon teleconverter, but that is a $2000 package; I’d also want the 1.7x converter and that adds another $480.

Is that this one: http://www.amazon.com/Nikon-70-300mm-4-5-5-6G-Digital-Cameras/dp/B000HJPK2C/ref=sr_1_1?ie=UTF8&s=electronics&qid=1257472224&sr=8-1 ? I saw that one but I'll need to wait until I get some Christmas money, then maybe save a little after that ha.

Thanks for the info!

Like Brooks said, fugettaboutit ;-) but seriously,

'uprezzing' a well taken/sharp shot works just as well as using any 2x teleconverter (unless mebbe if it's a 300mm prime lens with the expensive 2x t.c. made by Nikon

I not only read about that sort of thing but tried it--I've got a couple telecoverters (1.9x and 1.7 Olympus) that I attached (with tape to my D80 and the 'up-rez' is as good if not better than the t.c.s

As for getting a decent zoom lens which won't cost an arm and leg, you might want to try a Sigma 70-300mm APO DG macro (like I've got)...it doesn't have VR but in decent light you can get shutter speeds fast enough so you don't have to worry about camera shake (and it's relatively light weight). I use mine alot, for birding and airshows and it does a nice job. I got mine for less than $300 (new).

If you should decide to get the Sigma be sure you get the APO DG-macro model--the 'non-APO' model is cheaper but is not as sharp as the APO and, the APO model has little to no 'chromatic abberation' 'blue fringing'

FWIW...

Re: Like Brooks said, fugettaboutit ;-) but seriously,

For TCs to work decently you need fast lenses, like f2.8, minimum f/4.

But then, most people would then use 1.7x or 1.4x TC's instead of 2x, because you lose less IQ, Light and AF speed.

Yes

Just might be the best bang-for-the-buck lens that Nikon sells, in the top three anyway. I know some people will claim that the 50mm f/1.8 is the best BFTB, but I think it is the 300VR and I own both.

It really depends on the lens. I've used the TC14E II on both the 70-200 VR and on the AF-S 300 f/2.8 (non-VR). Image quality on the 300 didn't suffer much at all, but it was noticeable on the 70-200. Also, the loss of a stop can definitely impact AF speed, as I found out with the 70-200 and TC when shooting in shade.

Ah, a real world experience

That’s what I was getting at, I know people who successfully use both the 1.4 & 1.7 on the 300 f/4, but most reports about the 2x on that lens have been mediocre at best. Nikon’s TCs will only mount on prime lenses and your experience confirms that just because the TC will fit doesn’t mean the results will be all that great. On a f/3.5-5.6 consumer lens a 2x TC is a recipe for a lot of heartache.
