Thanks, Brian ... the 'in your face' photo is a bit like a 3D movie where something flies out of the screen towards the audience.

I look forward to seeing the chrome X-700!

In the picture my A900 has a 24-105, yours has the Tamron 28-75 - I have checked EXIF on an image taken with the Tamron on my A900 - there is no lens info sowing in LR. That said, looking at older images with 24-105 as the ID I see some taken at f2.8!

Further investigation - Exiftool reports lens as: Sigma 18-50mm F2.8 or Sigma 20-40mm F2.8 EX DG Aspherical IF or Tamron SP AF 28-75mm F2.8 XR Di LD Aspherical [IF] Macro

I found this earlier today, https://www.dyxum.com/lenses/lensesmkrid.asp - there are 9 lenses with ID 24 in that table.

When I look in the Lightroom collection and isolate the photos I must have taken with the Tamron lens, I get one, two, or all three of those lenses reported by the Inspector tool. No instances of no lens data being recorded.

Lightroom says the lens that was on your camera was the one used, even when the aperture is recorded at F2.8.

At least I can use the Tamron profile on the photos.

My head hurts.

Squaring the circle, for the benefit of others interested in stereo photography, the arrival of the silver X-700 has started an interesting conversation perhaps more suited to this thread.

Moving on, I have been diverting myself making some Found Stereo/3D Pairs ... unintentional stereo pictures, made from photos I took trying to capture a good view of the subject. You know, you take a photo, chimp, and decide to take a second or third. Under these circumstances I don't delete on the spot and tell myself I can sort the best picture out when I get back to home. Now, four years after a trip to Orkney I'm finding some stereo pairs to make.

The first, the Standing Stones at Stenness, came about when a car drove into the frame of the first photo, so I took a second and had clearly moved slightly. Enough to make a gentle 3D effect after the car was cloned out of the shot:


Found stereo #1: Standing Stones of Stenness

The second was taken at The Italian Chapel on Lamb Holm. I took a couple of shots trying to frame the altar and decided to take it portrait in the end. The landscape pair survived to make


Found stereo #2: The Italian Chapel

Finally, travelling around the eastern side of Orkney we came across an abandoned croft.


Found stereo #3: Abandoned croft, Orkney

Again, thanks for looking!

Used it today on my A99ii - LR reports it as 24-105. EXIF is a nightmare with third party lenses! Mind you it's not so good for Minoltas when. like me, you have more than one variant of a lens.

Some of the newer third party lenses do report the lens id properly. I have Sigma 150 F2.8 Macro and had Tamron 150-600, which do use an unique lens model name in EXIF. But obviously this does not help with the older lenses, especially in cases where the focal lengths of the lens and its fake lens id match.

These are very nice Howard, all three work very well as a stereo pair. I've done found panoramas but never found stereo pairs, I'm probably a bit more methodical at deleting double shots which I might regret now
