Originally posted by pasteofanchovie I'm not sure if I want to spend almost $400 on lens and end up sucking sand or dirt into it when zooming though, that's a lot of money in broke college kid dollars. I feel like I could just be being paranoid though.
I use extensively the 18-250mm and other lenses outdoor, with some 'attraction' to foul weather including subtropical rainstorms, dusty beaches, muddy rivers, .... I would like to correct two 'potential' misunderstandings.
Before the WR lenses, the Pentax users worked with many lenses and some 'glasses' (lenses) have had an excellent reputation for outdoor activities. The 18-250mm is one of these and there are numerous relevantthreads in this forum on the topic. Simply the 18-250mm can be strongly recommended based upon its track record.
second, you do not 'suck' water or dust when you zoom out with a classical zoom lens like the 18-250mm. But you need to clean/take care of the lens before you retract it. This is somehow the same the WR lenses because WR = weather resistance.
Importantly, the label WR does
NOT mean waterproof or dust proof. Every Pentaxian should read carefully the fine prints to avoid any disappointment.
Hope that the comments will help.
