Originally posted by LensBeginner I don't think that one could miss the reach
Obviously, everyone has different usage patterns, but since I purchased the 18-135 in September 2013, I've taken 1750 images with it. The five most frequently used focal lengths are: 390 at 135mm, 244 at 18mm, 181 at 36mm, 100 at 68mm and 98 at 48mm. Above 85mm: 568 or one-third. I also took 387 pictures with my A 70-210 after I acquired the 18-135, only for the extra reach. Before I got the 18-135, I took 873 shots with the DA L 18-55, 346 at 55mm, 105 at 18mm (12% or virtually the same proportion as I take with the 18-135). I almost never set aside time for photography, so my usage is nearly 100% snapshots, and most of those snapshots are landscapes, not event pictures. Even so, I maxed out on the long end three times as often as on the short end. I've only taken 86 pictures with my two prime lenses below 85mm, although to be fair, the DA 35 is only two months old. I've taken 270 pictures with my Tamron 90mm since I purchased it in April 2014, mostly for macro shots, but I've also used it for telephoto shots when I needed a faster aperture.
I have to agree with normhead, this new lens is designed to be a Canikon equivalent, not to compete with existing K-mount lenses. Whether that is a good thing or not, probably depends on whether the buyer is new to Pentax or not. HD coatings are the new default for Ricoh-Pentax, even the new DA 55-300 has it; there is no reason to expect the 16-85 to be noticeably different from the 18-135 optically. The only other reason for existing Pentax users to upgrade to the 16-85 is if they are moving up from the DA 18-55, and 16-17mm is worth $250 more to them than 86-135mm, but not enough to justify getting a separate UWA lens. How small of a piece of the current Pentax user pie does Ricoh want to develop new lenses for? Like the K-S1, this lens isn't targeted at PF members.
