Hello all, I am new to this forum and have a quick question for those of you shooting 16:9 (and also 4:3)...I recently upgraded to a crossover lens and now must sell my Canon 9x5.2 SD Wide Angle lens with a 2x extender...is this something that SDX-900 users would be interested in or is everything now HD? (or a dinosaur?) I have read some posts here of people looking and or recommending this lens...Thoughts or any marketing advice? Thanks from Seattle.
