I would have typed the full name, but there wasn't enough room to put "SMC Pentax-DA 18-135mm F 3.5-5.6 ED AL (IF) DC WR!
All I'm able to say at this point is WOW! I'm totally speechless! I've never owned a lens of this caliber before, but through a very diligent search through the Craig's List ads, I found this one, attached to a LIKE NEW K-50 (2,340 SA) in Portland, Oregon for what I considered "peanuts."
I've only taken a few test shots with it so far and I'm absolutely blown away at the sharpness and brilliance of the images. And the DC motor focusing is absolutely noiseless.
I've been making do with lenses that are far down the line, compared to this magnificent piece of workmanship. I feel like I've got the Royal Crown Jewels in my hands!
Through another Craig's List ad, I acquired a SMC Pentax-DA 18-250mm F3.5-6.3 ED AL (IF) about three weeks ago, but I haven't had time to give it a fair test drive.
I'm like a kid at Christmas time! Probably won't sleep a wink tonight!
