Pentax 18-250 issues

I took my Pentax version out for the first time today and wasn't overly impressed. Partly cloud weather and bright, the FAj 75-300 I had seemed noticeably better.

I also noticed when on the tripod if I point the lens down on an angle there is huge zoom creep, the zoom extends fully by itself. The lock is only good at the 18mm position for transport in the bag.

Now I'm thinking it might be a mistake. Also feel foolish as I bought the FAj 75-300, returned it for the 18-250 and now might switch back ...the store will love me

Well, I have the Tamron version and it's darn hear perfect...No zoom creep what so ever and it's pretty sharp...I would venture to guess, you have a bad one...I would exchange it, before returning it and give it another try...

My copy has shown major zoom creep as well, but according to pentax it's normal.

Well, I feel really dumb now. Looking at the 18-250 off the camera I noticed a heavy finger print on the element that faces the camera. This culprit is a 5 year old. LOL. How/when he did it I don't know. Kids today. ;-)

Lens cleaned and a test shot of the Moon tonight (albeit through haze) looks pretty good.

RAW
Focal Length 250 mm
Exposure Time 1/20 sec
Aperture f/8
ISO Equivalent 200

Could be worse -- you might've taken it back to the shop for exchange and they found the fingerprint on the rear element!

I have a DA 18-250 and okay it's not the world's greatest lens but it wasn't mega expensive and for versatility it is terrific. Mine doesn't zoom creep just by pointing it down though, it has to be shaken a little.

because some of it is normal.. send it back to pentax and have then tighten it up to stop the creeping.. then we can all complain that the focusing ring is hard to turn...geeeesh.

Well, it may be normal in your world, but not mine...Nice and smooth and no creep.

My lens does exhibit zoom reep. It is kind of annoying but nothing I can't deal with.

The fact that pentax kept the lock @18mm shows they expect zoom creep from this guy. This lens is pushing a whole lot of boundaries, and zoom creep is one of the tradeoffs.

I too used mine for the first time on the weekend. Aside from noisy AF and zoom creep it performed well. Great for overseas travel where lugging 10kgs of kit isn't an attractive option.

Heck, my excellent Tamron 28-75mm f/2.8 has zoom creep. It was less than $400, it takes awesome photos. As long as it doesn't creep while I'm taking a picture, I don't care

I have to hit mine with a 24-ounce carpenters hammer to make it creep. I have found no creep with this lens ( unless my husbands poker bud's are visiting)
