I just bought a used 200-500 Tamron on ebay for a very reasonable price, in Nikon mount. Thinking I may need a little more reach for wading birds in our area, I considered a Tamron SP 1.4x extender. Concerned with compatibility, I emailed Tamron, to check compatibility. To my amazement, and surprise, I was told Tamron extenders "were not for use with digital cameras". They referred me to a technical bullitin that said image quality would be extremely degraded, and there would possibly be communication errors. Their SP series are said to be Pro -Level, so i was surprised. I was aware I would loose auto focus, but I am amazed Tamron is letting the extender market slip away. Anyone using an extender with this specific lens? Which extender?
Thanks in advance
