dannirr Posted January 23, 2007 Share #1 Posted January 23, 2007 Advertisement (gone after registration) I need help please: My M8 does not detect the WATE - the EXIF data is essentially blank fo rlens information. Lens detection is turned on. Advice? Thanks, Danni Quote Link to post Share on other sites More sharing options...
Advertisement Posted January 23, 2007 Posted January 23, 2007 Hi dannirr, Take a look here M8 lens detection?. I'm sure you'll find what you were looking for!
Englander Posted January 23, 2007 Share #2 Posted January 23, 2007 Apparently it is that way for all WATEs (I've been checking around with other owners) but the lens detection--when switched on--definitely helps eliminate vignetting. So, even though nothing shows up in EXIF, it is recognized by the camera. Joe Quote Link to post Share on other sites More sharing options...
scott kirkpatrick Posted January 23, 2007 Share #3 Posted January 23, 2007 I'm also finding that reporting a detected lens in the EXIF is rather hit or miss. I can't say for sure that vignetting corrections are being applied because I don't often shoot scenes in which this would be obvious. I'm using mostly the 28/2.8 and I have seen a few cases where no lens information appears in the EXIF. edit: I just went and checked in my Pbase gallery. There are a whole series of 28 Elmarit shots that have defective EXIF, but after a few lens changes the EXIF is correct again in later shots. My impression is that if I don't turn the lens all the way to get a nice crisp click, it will still take pictures, but the bar code will not be quite aligned and lens detection will not work. I have an IR-cut filter on that lens, and will have to see if the cyan drift is reduced when the lens is properly seated and not so when it is a little short of a full twist. scott Quote Link to post Share on other sites More sharing options...
teehas53 Posted January 23, 2007 Share #4 Posted January 23, 2007 Here's something that was unexpected (to me at least) - My CV 50/1.5 (which is not hand-coded) shows 50mm lens EXIF info. This is a screw-mount lens in an adaptor no less. Now, if we believe that it's the bar code that IDs the lens in use, this makes no sense. The mount triggers the correct framelines of course, but the camera should have no way of knowing WHICH pair of framelines are correct for the actual lens being used... Curious, no?
