Pentax DA* 55mm F1.4 - Please Read

PentaxForums.com Marketplace Listing

Item for Sale
(SALE PENDING) Pentax DA* 55mm F1.4

Asking Price
250.00 USD

Item Location
Colorado (United States)

Item Description
For sale is a Pentax DA* 55mm/f1.4 SDM. Lens was acquired from a local individual (NOT EBAY) who was selling another lens I was interested in. The deal presented to me at the time was too good to pass on. I'm selling it due to the issues noted below, plus it is somewhat of an overlap with lenses I already have.

THE GOOD:
  • Glass is clean and clear, no haze, no fungus.
  • Aperture blades are clean and snappy.
  • Focus ring rotates smoothly. No grinding or gritty feel to it.
THE BAD:
  • Lens has Auto-Focus issues! For whatever reason AF will not work at first turn-on. But if you wait about thirty seconds or so, it will decide to work – most of the time. Sliding the lens' AF/MF switch seems to help and brings AF back to life. However, if AF does start to work, a mild but audible “squeak” can be heard emanating from the lens while hunting for focus.
  • I don't have any accessories for it (hood and/or pouch).
  • Caps are generic (if you consider that bad).
With the “bad” issues noted above, it is very likely the SDM is failing on this lens. Unfortunately, I did not notice the problem initially when I first tested it. On the other hand, manual focusing works without issues. Optically and cosmetically, the lens is in very good to excellent condition. Lens would be ideal for people who would rather manual-focus, or live with an intermittent AF – which could fail at anytime.

My 55/1.4 has the same problem for very long time. It actually has some high pitch noise during AF maybe on the 1st day.
But it still works fine, only needs a few seconds of "wake-up" time if left unused for a while. I don't feel it is a big deal. after warm up, it works just fine. Turn the camera off for a few hours and turn back on, AF jumps in immediately. AF on 55/1.4 is slow(lish) anyway.

My Da*200 also needs to wake up whe first turning on the camera. I do not know if this is first stage of SDM failure or not. For now, I have no issues.

There have had some inquiries regarding screw drive conversion, I thought I'd put the answer here.

Can the lens be converted to screw drive? - No. This particular lens is SDM only. There is no screw drive to convert to.

For some reason this lens wakes-up faster on a K-01 than on a K5?

Agreed, I just did a comparison between this and my Takumar 50 1.4 and 55 1.8. this lens blew them away in IQ at wider apertures. Very impressive at f1.4
