Aperture 2.1 not reporting my lens correctly

[Sauk]

The lens is the 120-300 Sigma F2.8 lens. It reports it as a Sigma 17-35mm f2.8-4 EX Aspherical HSM.

Is there a way to fix this?

[Tony-S]

That's strange. What does DPP report it as? Might be the lens causing the problem. I'm not sure if it's changeable in Aperture...

[Sauk]

not sure I don't have DPP installed.

Has anyone else with this lens experienced issues with aperture?

Post a picture with the full exif intact. We should be able to tell from there.

[Sauk]

This should have full exif information

from CS3's file info - no lens info only the image data...

As per the Apple site: http://www.apple.com/aperture/tutorials/#adjustmetadata-editmetadata

The grayed out parts of the metadata cannot be changed in Aperture.

When I pull this into Aperture 2.1, the lens model is blank, but there is other metadata there.

[sadatk]

Yep, not getting any lens info from that image.

Maybe try posting a raw?

[Sauk]

Yeah I could do raw, let me get it hosted on a site.

Preview on Mac for the CR2 file shows:

- Lens Model: Sigma 17-35mm f2.8-4 EX Aspherical HSM

Interesting though, is this from the same file in Preview:

- Lens Info: 120, 300, 0, 0
- Focal Length: 274

[sf1]

The raw file does show the lens model as being the Sigma 17-35mm f2.8-4 EX Aspherical HSM.

As stated above, I do not think you can change this in Aperture 2.1, but someone will probably be able to help you out using another program.

[sf1]

Funny, the focal length is 274 mm - kind of long for a 17-35mm lens.

Hey now, stop stealing my thunder! ;)

[Sauk]

yeah at first I thought it was because of the 1.4 ext I used a few times, but then I started to notice that it reported that lens even with it off. Kinda annoying. I might give apple an email about it to let them know it isn't reporting correctly.

Thanks for all the help

:lol: No problem. :rolleyes:

In CS3, the lens is reported as 120-300 mm. Seems this maybe an Aperture only problem.

[ifonline]

If both Aperture and Preview report it wrong, I would say its an OS X problem, not just Aperture.

yeah I will have to send an email about it.

Or the lens could be reporting wrong. DPP uses its own software to pull that info, not OS X (like Aperture, Preview and iPhoto do). That's why I was curious to know what DPP thought of the lens.

Lightroom shows the lens as 120-300mm. (doesn't say Sigma or such). Preview i'm getting the same as others.

[Sauk]

so could it be canon software not writing it correctly into the exif?
