Latest Review Posted | HD Pentax-DA 1.4x AW AF Rear Converter The HD DA 1.4X is a must have accessory if you own a DA*300/4, FA*300/4.5 or F*300/4.5. Forty percent more magnification with almost no IQ loss, especially with the DA*300/4. The TC also works very well with the F and FA 100/2.8 macro lenses giving a very high quality 140/4 macro lens.
I’ve tested the converter with my DFA 150-450 and it works well for subjects under 100 feet away, after that, at least with my lens, IQ degrades to the point where enlarging files from the 150-450 alone gives better results. No such issue with the DA*300 which is the nearly permanent home for my converter.
I was lucky enough to find a used copy of this lens for $250, though I would still recommend it a the full $397 current asking price. |
