Originally posted by Robert N I am considering purchasing a HD DA AF Rear Converter 1.4X AW to use with my K-3 camera and HD DA 55-300mm F4-5.8 ED WR lens.
Does anyone have experience of this combination and can comment on:
Image sharpness/degradation compared with using the lens only.
Reduction in viewfinder brightness (has this been a problem).
Autofocus performance.
Accuracy of the camera metering system.
Any adjustments to the camera settings required to optimise performance.
Any problems you have encountered using this combination.
Many thanks for your assistance.
Robert, should you decide to buy a da 1.4tc, you could look on the marketplace, I am putting my 1.4tc up for sale there tomorrow. You can also pm me of course. I have used the 1.4tc with my DA560, but ultimately, a very long f5.6 lens is not ideal with the tc. and I now use the lens bare and crop. So although in honesty, I could nit say that your lens would be very good with the tc, you might want to take a chance without paying the full price.
