I am using a Nikon D80 with Nikkor 18-135mm f/3.5-5.6G ED-IF AF-S DX Zoom kit lens.

Is it better to save my pennies to get a bigger lens or buying a teleconverter 1.4X or 1.7X a good answer?

If the teleconverter is the answer, do I loose anything other than 1 to 1 1/3 stops? Quality? Curvature on shots?

I keep on reading about the 70-200 VR lens, but I had no idea that lens is about $1500 when available; it is usually back ordered. I don't have that kind of cash since I just bought the camera.

I have the D50 and the Sigma 70-300mm. It is a good lens. Not top-notch, but it's only $200 :D It's best in bright lighting, at less than full zoom.

I'm not versed in TCs, though. In fact, I'm thinking about getting the Raynox 2.5x macro TC myself. I'm interested in what comes up in this thread :D

i tried the soligor and the nikon 1.7x TC. the nikon one was a bit sharper, lost less contrast and is built beautifully. however, it is limited to only a few lens' of which the 18-135mm is not one of them.

the soligor's are widely recognised as being the better of the 3rd party TC's. 1.4x lose bugger all clarity and the 1.7x loses a little sharpness, 2x TC's lose a consdierable amount in most cases.

not sure if its really worth it in your case to be honest. 135x1.4 = 190 or 135x1.7 = 230mm. i think you may be better off getting the 55-200mmVR or spend a bit more and grab the 70-300mmVR. in both cases you get VR which you need the most at the long end.

A TC on a 18-135 kit lens?
The only upside I can see is that you will get rid of the vignetting...
But you will lose AF ability, especially if you would go for an 1.7x or 2x TC.
And with a 2x TC you will also lose a lot of image quality, that just is the nature of the beast. And for what? To get to 270mm?

It seems to be a much more logical thing to get a 70-300 lens.
Depending on your budget, a Sigma 70-300 f4-5.6 APO DG Macro (~$220 USD), or a Nikon 70-300 f4.5-5.6 VR (~$500 USD).

This way you do not lose AF functionality, and in case you can afford the Nikon, you also gain VR, nice at the tele end.

So, what I am getting from all of this is to save my pennies and get a true lens, not a TC.

Thanks for your responses. Always greatful.

mind you...if you buy the soligor tc it will fit your existing lens but also fit any new telephoto you get in the future which will give you more reach again, so really its not like you'd be wasting your money. you're just adding a step in between.

the 18-135 is sharp enuf to carry a TC so i doubt you'll notice much IQ dropoff and with PP you can correct any loss of contrast via curves pretty easily.
