Apperture does not appear in EXIF

[kingmillo]

I use iPhoto to import M8. However, in the file info the apperture setting is blank. Even the max apperture is wrong. It says max f1.0, but mine is 2.8. I am using 50mm cron and 28 elmar. Does anyone have same issue? You think it is the iPhoto or the exif? And some speed values are displayed as 0.0333, for example, instead of 1/##. Annoying. I had to use calculator 😀.

there is no mechanism between the lens and the body to communicate the aperture of the lens. Just look at the lens mount!
You just have to remember or write them down as you would with Medium or Large format camera.

It is not an issue - it is a feature 🙂

The M8 is for the most part a manual camera. And the aperture isn't electronically controlled. So the camera has no idea what aperture is being used. Therefore you will never see the aperture entered in the EXIF data. Though you can use an editor to put it in yourself if you remember.

I use Apple Aperture and my shutter speeds come up normal, as in 1/125. Perhaps you have something set differently.

Look at Phil Askeys review on dpreview. He states the same. There is NO electronic contact between the lens and the camera, so the aperture is NOT recorded. I guess you have to buy a real camera now...

This incorrect.Actually the estimated aperture is recorded in EXIF The camera uses the external light meter (blue dot) for that. It is just not displayed, as it is not 100% accurate. Some EXIF readers will show it. In my experience, accuracy is close enough.

I guess you use uncoded lenses. In that case max aperture is recorded as 1.0. Otherwise the correct max.aperture is displayed.

No i use the 6-bit coded lens.

I've imported M8 files via Aperture and CaptureOne. The latter shows estimated apertures and both sometimes display the shutter speed in decimals rather than fractions.

I suggest you test CaptureOne and see if the aperture is presented there. Your M8 most likely came bundled with a license for that application.

C1 actually calculates the aperture (based on what jaapv said) and sets the respective aperture exif data. It shows up e.g. in Lightroom on C1-processed JPEG files. For that AFAIK the latest version of C1 is required, which can be downloaded at their web site (www.phaseone.com).

My M8 comes with C1 but somehow it refused to install in my intel mac. I read some folks also having same problem. So never tried C1. I think I will. C1 any good?

C1 is considered to be very good (if not outstanding) for processing RAW files and I do use it on my MacBook Pro. The early C1 4 beta versions suffered from teething problems, such as install difficulties and crashes. The latest version is quite stable from what I've done with it so far, which is just a couple of hundred images.

I'm not the biggest fan of their new interface. The old one was simpler and faster for me, especially when it comes to applying anything to more than more image (processing, white balance etc.). I have, however, decided to give it an extended testing period.
