question for Da 14mm owners

Hi Folks,

I've been looking at this lens since it's $100 due to the Pentax sale (over March 31st).

When I was testing it out, I noticed that the focusing ring move normal left to right, but when going back to the left, I could keep turning it to the left even though the focusing was finished - maybe a dumb question, but is that normal?

I currently have 18-55 3.5-5.6 lens that came with my K100D and the kit lens 55-300 which I bought after.

Looking to add the 14mm to my K7.

I'm also looking at getting a used SMC M 50mm 1.7 - heard that is a solid lens as well.

Cheers,
Keebler

It's called Quick Shift.

No, I think he's talking about something else. Most lenses with quick shfit still have hard stops at the end of their focus range, both at infinity and at minimum focus distance. Some lenses apparently let you keep spinning their focus rings round and round and round and round and they never stop even though you've already hit the end of the focus range. Seems to me someone else was just observing the same thing about his DA14 on dpr.

Hi Marc,

you're right. I could keep turning it and was wondering if that was a problem with the lens as my others have hard stops at either end.

thanks,

The DA 12-24 has hard stop at both ends, but the DA14 uses a clutch with no hard points, it just "keeps on going", like the bloody rabbit.

Yep. So does the 16-50 and the 50-135 DA*'s. Some sort of mechanical protection perhaps?

I think this is the behavior of the combination of IF and Quick Shift.

I have 14mm and it behaves just like yours. So, it is not a sample problem.

Yes it is, probably the best $$ I have spent on a lens to date. Fast, sharp, great overall IQ and under $30--amazing

For what it's worth, many of my MF lenses were Free by the time it was all said and done. If you can resell the other two lenses, you may actually end up at a profit situation (depending on the lenses of course). I do this all the time. It's a bit of work but sometimes very much worth it. My K30 f2.8 for instance, I sold two of the lenses that came with it, the camera body that came with it, and a couple other things. I am now in a profit mode on that transaction and I still have the lens (in addition to a Pentax A 35-105 f3.5).

Keebler-
I posted the same Q over on the other forum. I can add my name to the list of DA14mm owners who have observed exactly the same focus ring behavour. Based on replies here, it's good to know that it's a characteristic of the lense rather than a defect.

Now that I know that the lense is in good shape, I'll sell it as I purchased that DA12-24mm last summer and certainly have no need of two wide angle lenses.

Hi folks,

Just wanted to say thanks again for all of your insights/suggestions and feedback.

I ended up purchasing the DA14 with a Hoya Pro1D circular polarizer (which I plan on only using on those bright days).

Anyhoo, here's my first shot with it

Thanks again!
