Originally posted by Spodeworld I just took 3 jpgs @ ISO 200 at 17mm. 19mm and 21mm. The SR was on and the shutter speed was about 1/15" for each. I downloaded Photome, but I am not seeing where the SR Focal Length is displayed in the interface.
It's in the section labeled Manufacturers Notes.
Since it's below 0 outside and I had no desire to get out and do anything, I spent a good while looking through my photos and reading the exif in PhotoME. My K5 regularly listed the SR Focal length as 45mm when I shot at 17mm. I began checking some other focal lengths and found similar results. There were also slightly off SR results at longer lengths but only by a couple of mm's and not enough to likely cause a problem. I also found some differences in other lenses too, but only by a very little. Then another problem surfaced. I went back and looked at some of the other data in those 17mm shots I checked earlier and they are now listing the SR length as 52mm!
Since these are all pretty sharp photos, I'm beginning to think this is a problem with PhotoME. Why would the data change? I also found instances where my DA 10-17 was listed as an "M" or "K" lens even though in other places in the data it is correctly listed as a DA. I think PhotoME isn't correctly reading the data. My AV software also has tried to block PhotoME as malware.
Rather than send a lens back, the real answer to all this is to follow the rules of photography and use a tripod if you want to shoot at slow shutter speeds. It's always a crap shoot under 1/30 and for longer lenses, the minimum is usually the focal length; don't try to shoot with a 200mm under 1/200, etc and even that is no guarantee.
