Here is a gem of a lens... if Internet rumors can be trusted, even Zeiss admits that this is the sharpest lens they've ever made. Although I'm not a person that's big on sharpness, even I had to do a double-take when I viewed some of its images at 100% and marvel at its incredible details. Also, as much as I love a fast aperture, I felt it's a bit unnecessary on a wide angle lens since I'm most likely not going to try to isolate my subjects. I think it will take me a while to get use to this wide view, but I accept the challenge to incorporate more of the scene in my images.
Lens coding cannot solve the last problem, which means in my automatic image border, it will display the wrong lens name! Lightroom doesn't allow the user to easily modify the lens meta data in the EXIF. So I searched high and low, and found a nifty Lightroom plugin called "LensTagger". Now after I import my images, I can simply find all of the 24mm Elmarit images and change their lens name to "Zeiss ZM Biogon 25mm". The plugin will update the EXIF data in your original file, so after it's complete, you'll have to tell Lightroom to reload metadata from files again. Now, I'm a happy camper!
