Pentax DA 1.4X TC Review by PF

http://www.pentaxforums.com/reviews/pentax-da-14x-aw-af-rear-converter/introduction.html

As usual, those test images by PF guys are somewhat crappy as photos. However, these are good enough for the readers to judge on the image quality and all the differences, if any, when compared with other products. Do bear in mind to judge on the test samples yourself but not rely totally on the words made with their comments nor even with the ridiculous high marks given by them, which should be the better way to go for getting more meaningful conclusions of yours. :-D
