For K-3, I'd just get UHS-1

The UHS II U3 may be better, but not K-3 can take advantage of
The Class 10, you can ignore (for best K-3 performance)

Fixing Tamron Adaptall P/KA Adapter

When the adapter is put on the lens, and AE lock engaged, the lens diaphragm is closed.
Move the level from the back of the adapter, the aperture would open, and when the level let go, the aperture will be closed.

I'll have to study the lever and its shield to figure out the gap thingy.

Re-read the k-mount page, try to understand the following: "The lens aperture ring has an additional setting that is marked with an "A". It is always the left-most aperture setting, and therefore functions as the lens' narrowest f-stop. Because of this, when the "A" setting is engaged, the lens internal mechanics pull the diaphragm blades towards their "as closed as possible" position. On the other hand, when the lens is mounted on a camera body, the diaphragm release counteracts the lens mechanics, and keeps the diaphragm fully open."

Appreciated

The problem is, the lens stay all the way closed all the time. The VF is very, very, very dark, just cannot focus.
If I move off the 'AE' position, I can do the "stop down" by turning the aperture ring to, say, f4 and I now can focus.

If the lens should stay wide open unless doing a preview or actually trigger the shutter, could you mind let me know when the lens becomes open? as soon as put on the camera or after the camera turned on?

It's closed, even if put on camera and move the e-dial, the display could be 2.8, 4, but the aperture stays closed

---------- Post added 09-12-2015 at 09:09 PM ----------



Yes, it is in AE position.

These are the steps I use:
1. set the lens to its widest aperture (2.8)
2. push the adapter on, when snugly start turning it, until the latch clicks in then spring out to its original position
3. set the 2 tabs to the slots (if they are not there yet)
4. set the lens to f22, push the AE-lock tab, now set to f32/AE, the lens is closed down (only a small hole formed by the aperture ring)
5. put the lens on camera
6. turn on the camera in Av mode, set the focal length,
------> the LCD may display as f2.8, or f4
------> but the VF is dark, all the time (while the lens in 'AE' mode) that it's hard to focus
------> and the aperture stays closed

Thanks for all the replies, maybe I'll bend the aperture limiting tabs in a little bit? Should the inner white part touch the lens wall? It might be possible a bad adapter, but I am trying to identify.

I guess my questions are:
1. when you set the lens to 'AE' mode, does the lens go wide open or stay closed?
2. when you put the lens on camera, turn on camera in Av mode, is the lens wide open or closed?
....
3. I can imagine that one can turn the e-dial, to, say f8, and the lens is still open, correct?

Well here I am digging this several year old thread out.

Recently got a Adaptall-2 lens, and the pka adapter; after seating the lens firmly to the adapter, now the aperture is displayed on the top LCD and VF, the wheel can change the f value displayed but doesn't seem to have any effect on the lens (i.e., the lens seems to be left at f32). Any suggestion?

TIA

It could be tedious sometimes, depending on the lenses you use.
On windows, there's an ExifToolGUI app that uses the exiftool program, with which you can select a group of pictures and do a "Modify=>Exif:LensInfo from makernotes" and you may still have to set the lens manually if it's ambiguous (e.g., Sigma lens)
Then you can import/resync/read-metadata from LR so the lens will be displayed in LR

Besides, it's not much use with the 1-year warranty for these fancy (SDM) lenses, should better buy some extra warranty to be safe

But they would offer instant rebates (discounts) for other mount. Like the Sigma 18-200 II lens. The price you can find for Canikon/Sony mount is 20%-25% lower than the one
you can find for PK mount.

The Sigma, being a ST, I don't think is capable of fire wirelessly.
You need a "super" model.

HTH.

A bit different voice here.
The 50-135 DA* is all good, all excellent, except that the HSM (SDM) might not
be reliable, the auto-focus could stop working with no reason.

And Pentax has a poor 1-yr warranty, at least in the US.
If ever it fails, will you spend another several hundred to fix? Just a if...

If you do buy this lens, try to get extended warranty ...

Regards.

First time posting pictures.
Took some macro pictures of the flower, hand held, aperture f16, or f22.

Lowest quality jpg, untouched, with K10D. Do have raw file though.

Some are 1:1, some are 1:2.
