In the past week, I have been tracking some lenses on ebay and I came across the Pentax 1.7x AF Teleconverter. There must have been about five days left on the auction and the price was already up to $150.00. Friday morning the auction closed and the final bid was at $410.00!!
I was flabbergasted, I never expected a teleconverter would fetch so high a price.
What is so special about this teleconverter? I am quite indifferent about using teleconverters in general; the gain of focal length being offset by resultant loss of f-stops do not appeal to me. I acknowledge the uniqueness of this particular unit's ability to auto focus-assist some manual lenses, but novelty of using the unit quickly wear off with the noticeably darker viewfinder. Your thoughts would be appreciated.
Thanks,
