Message: <blockquote data-quote="STM" data-source="post: 113877" data-attributes="member: 12827">Teleconverters work by spreading out the image from the exit of the lens. When they do this, resolving power is going to be lost, it is a physical fact of life. They will of course lessen your depth of field as well and you lose at least 1 f/stop. If you have a slow lens to begin with, now you have an even slower lens. The better ones degrade the image less but are still not as good as a prime lens of the same focal length as your lens and the TC. Nikon's TC-e teleconverters are very good but the are also as or even more expensive than many lenses. I have both the TC-14B and TC-300 for AIS Nikkors and they do come in very handy with my 300mm and 600mm Nikkors but like I said, they are rather expensive for what they are.</blockquote>
