Why are you bringing this up here? I made my above statements with the certain knowledge of the EXIF format and its implications. You may remember that it was me who provided a tool to "fix" the K-3's DMG files to make them readable by Apple's software before Apple provided a fix. So, no need to educate me on it. Your comment seems to only add more vagueness to it, from my view, confusing others. For instance, the last part about "corrupt the existing information" does not apply to any of my statements above because none of them are about files modified after written by the camera.
If you have a particular doubt about what I wrote that's not just a general "be careful" reminder, please point it out, though. Otherwise, please do not assume that others make mistakes before you have even verified that they're wrong. I had to fight the same in the mentioned thread about the HSS bug in the K-3 a few weeks ago - initially everyone assumed I could only be wrong, no one taking me seriously. I resent that, especially if it keeps happening.
Until then, I stand by my statements that I had even explained in more tech detail than you just did:
* The K-3 put different Lens ID codes (sometimes 2-0, other times 2-215) in the files for the same lens.
* The codes for some of the Pentax Exposure Program modes are not yet decoded by Apple's software (IIRC, Lightroom got some of them wrong as well, but I found no way to tell Adobe of such bugs).
* The Apple software doesn't read the serial number from the EXIF data correctly.

Okay, so the fact that K-Three's JPEGs didn't show the lens name is due to the fact that they're not the originals from the camera but were generated by some other software (Aperture), which failed to include the lens ID, somehow. If that's what happened, that'd be a separate issue, though one that's disturbing as well - a RAW-to-JPEG conversion should not drop such metadata.
So it appears, unless NZ_Ross finds otherwise when he finds time to do another test, that the original issue of this thread has been fixed by Apple recently, at least.
Unrelated oddities that remain, are the mismatching camera serial number, the unknown "Exposure Program" values (which I reported already to Apple) and the odd "A Series" lens identification (this last one is clearly caused by the camera, not by wrong interpretation of an EXIF reader).
The camera serial number appears to be rather random when shown by Apple's apps. I've got a lot of RAWs that show a zero here, while others show numbers such as 1212696648 and 1482246216. OTOH, when checking them with exiftool, I get consistent numbers ("Internal Serial Number": 7028149 and "Serial Number": 2576399 - and this matches the serial number printed on the body's bottom). So, here, again, it appears to be another bug in Apple's software.

BTW, another EXIF issue is, as we can see in K-Three's screenshots, that the "Exposure Program" is "unknown" (due to special codes that Pentax uses exclusively). That's another issue that I've already reported to Apple, but those are obviously all low prio issues and might never get fixed.

NZ_Ross, note that I had made a mistake in my last post - I had first written that I still had an empty Lens name with my RAWs but it turned out that those were empty fields of my A 50mm lens, not the 18-135. I got confused. So I've now corrected my post, stating that the 18-135 does not exhibit the original issue any more. It would be nice if you could re-test on your end as well, provided you have recently installed all the latest OS X updates.

The results here are all so erratic. I just re-tested with my 18-135 and found that the lens name is now shown in RAW and JPEG images, whereas K-Three shows that it does for his JPEGs. The fact that it works now for me may have to do with the recent OS X updates which I've all installed. But why doesn't it work for K-Three then?
(This reminds me of an obscure issue I found out a few months ago where I pointed out that certain flash operations did not work correctly with the K-3: https://www.pentaxforums.com/forums/172-pentax-k-3/254837-hss-sometimes-not-w...confirmed.html)
Then, today, I noticed yet another irregularity: My SMC 50mm/1.7 does show up in some pictures correctly as "A Series Lens", while it's blank in others. Between those shots I had different lenses on the K-3, and after re-attaching the 50mm all the images in row were having the problem, while all others before were good. So, this suggests that the lens ID was not properly registered by the camera when re-attaching the lens. Oddly, though, all other parameters were properly identified, such as the aperture (which was most times at f/1.7, and I had no other lens used with that wide aperture). I then checked the EXIF data with exiftool and found that the correctly identified lens has the numeric values "2 0", whereas the images with the blank lens had "2 215". This is most surprising because whereas 0 indicates a "don't know" value, 215 is rather specific and should be identifying the precise lens. This is all so weird. However, this effect with my 50mm lens is different from this thread's main topic because the main topic's issue does not have this variable Lens ID issue. It's just irritating me how this is all coming up now, one small problem after another, all with my new K-3.
Now, back to the original issue. Below are two screenshots from my current. As you can see, both RAW and JPEG show the Lens name correctly. So, for me, the issue of this topic appears to be fixed. Remains to be seen why K-Three still has trouble (but with JPEGs only, while my original issue was with RAWs but _not_ with JPEGs). Same with NZ_Ross.
@NZ_Ross - have you updated all your Mac software in the past days, including OS X 10.9.3?

BTW, Apple has confirmed this is a known bug (radar #16395119) but doesn't give any details on it. It was known before the last D.C. RAW update, though, so they may not deem this an important fix so far. If any of you has an Apple account and cares for Apple to fix this, it might help to report this yourselves at https://bugreport.apple.com/ |

And just to confirm: You don't have an 18-135, right?
And what makes you so sure that this is Apple's, not Ricoh's, fault? (I know the answer, just like to have someone else draw their own conclusions.)
---------- Post added 24th May 2014 at 08:13 ----------
So, you do see the 18-135 identified in Aperture when you look at the RAW image? Can you show us a screenshot that also shows that you're really looking at the RAW file?
How do you make Aperture to show you only the RAW image when you have both RAW and JPG pairs imported? While iPhoto keeps them as separate images, Aperture usually combines them into one, and I haven't figured out how to view them separately thereafter.

Sure, that's all fair to say. But it has nothing to do with the topic of this (my) thread.
And I sure do not agree that this is not an issue. It is for me, as I do not see the lens type in Aperture, which bothers me (a little). I find it rather disrespectful to judge me on what I find to be an issue or not.
I am only asking for confirmation of my findings. You're trying to give explanations. That's not what I'm asking for here. If this is a bug in Apple's software, it's up to Apple to analyse and correct this issue. But without having proof that this is a repeatable issue and not just happing for me alone, I cannot make a point and report this as a bug to Apple. As a fellow programmer you should know this procedure about bug reporting ;)
So I would appreciate it we could now focus on my own question, which is still: Can others reproduce this issue? |

@Miguel - the lens types are not misidentified, if that's what you tried to suggest, because this is with lenses who are well identified when used with a K-5, in my described case. So I don't see what you're getting at. Please elaborate.
@NZ_Ross - thanks for confirming my findings. Do you also see that it works right with other lenses? Also, does the DA 55-300 show up when using DNG format?

Yes, that's right. But that has nothing to do with the issue in this topic. This topic is about lenses not being identified AT ALL, the lens info remaining empty.

Could you please post the full description of that lens name as it appears in LR or exiftool? I wonder if it's particular chars or its length (the one for the DA 18-135 is pretty long).
Uh - that's happening with a K-5? Not seeing the problem with my K-5, only K-3.
How did you come into posession of the Porst lens, BTW? Lived in Germany?

One problem solved, one remains:
1.
There is no problem with LR 5.4. My mistake was that I had originally imported the images in LR 5.2, which was unable to process the Lens Type, but when I updated to 5.4, I forgot that I need to tell LR to re-read the EXIF data. Now that I've done this, LR shows the data as expected.
2.
There is still a problem with Apple's apps (iPhoto, Aperture, Preview).
It's actually two-fold:
With DNGs, the Lens Type is always shown.
However, for JPG and PEF, it depends on the actual lens I was using:
While my DA 21mm shows up, my DA 18-135 DOES NOT.
So, to summarize:
The problem exists only with JPG and PEF but not with DNG, only with Apple's apps, and only with certain lens types, e.g. the 18-135.
Now, can someone confirm this?
---------- Post added 5th May 2014 at 21:22 ----------
That's not an issue in my tests - The Lens type is shown prominently in both Aperture and iPhoto, and both show an empty field here in my tests.
@DogLover - I'm using the latest RAW update (5.04), so that's not an issue here, either.

Thanks for trying to help, guys, but you do not have to explain software to me. I have been a developer for 30 years.
I just wanted a confirmation that others see this problem as well. That's exactly what I've been asking, BTW: "Is that a known issue?".
@Adam - LR 5.4 is the latest version, and that's what I've been using for my testing.
Also, exiftool sees all the data including the Lens Type and Lens ID, correctly
Will try a DNG next.

Would you please help me confirm (or refute) a possible small bug with Apple's imaging software related to the K-3.
Especially, if you have a DA 18-135mm or 55-300 WR!
I found that Apple's apps (Preview, iPhoto, Aperture) are unable to show the lens type for my DA 18-135mm.
Is that the case for you, too?
Note: This only applies for images taken with the newest model(s) like the K-3 but not the K-5, for instance.
Here's how to check:
Launch iPhoto (or Aperture) and select images taken with various lenses. Click on the "Info" button or tab. In iPhoto, the top right should display the camera model and below that, the lens type. But in my case, the lens field remains empty. See the attached pictures below for an example how it should look like (with a K-5) and what I see with my K-3 instead.
Can you confirm that? I.e, do you also have a blank lens field? Or does the lens name appear despite it being a 18-135 or a 55-300 WR?
In both cases, please list which file format (JPG, DNG, PEF) you're using, which lens and which camera model.
It's suspected that the issue is only with the K-3, and only with a few lenses (18-135, and possibly 55-300 WR). If you see the lens type shown with any other lens, then that's expected, and you do not need to post your results here, because we're only looking for misbehaviors here.
