Bringing you this site is my full time job (typically 60-80 hours per week). Thus, I depend solely on the commissions received from you using the links on this site to make any purchase. I am grateful for your support!

Coupled with fast primes this TC really shines. Outstanding IQ/AF speed with my 200 f2/300 f2.8 VR's This little addition has actually saved me thousands of dollars not having to purchase a 500...love when that happens!

One of the true perks of shootin' Nikon

None

It was hard enough justify $1600 on a 70-200 2.8 VR lens, spending $5500 for a 200-400 F4 VR was out of the question. Still there are times when 200 isn't quite enough reach to get the picture you want. The $420 for a TC-17E was a compromise that I could live with.

Extends focal length of certain Nikon lens by a factor of 1.7 at a cost of 1.5 F stops; Makes a 70-200 2.8 a 120-340 4.8.

Works with a limited number of Nikon's catalog of lens

I would rate the 1.4TC as the only TC that will yield excellent results across the board. The 1.7 is a good compromise, but dont expect it to yield tack-sharp results on every lens. You need to stop many lenses down at least two stops when using this TC to achieve max sharpness.

Good reach; works flawlessly with top-quality glass

Not as sharp as 1.4TC

Very nice accessory for a relatively fast lens (2.8 or less). Somewhat expensive, but excellent optical clarity. A great way to nearly double your reach with only a small penality in light loss.

The converter is very easy to use, and with Nikon's modern lenses it enables all functions; Optics are excellent, and very little is lost in sharpness; The 1.7 is a very nice middle ground between the 1.4 and the 2.0.

The converter is expensive; and a little inconvenient if you are in a hurry
