[QUOTE="Blade Canyon, post: 503191, member: 15302"] The first thing would be to post some of the images you are complaining about so we can see the EXIF data. Second, that lens was a very wise choice! They are so inexpensive yet that 105mm 2.5 lens was the king in its day. I have the same lens and it only cost $75 (but also have the newer AF 105mm 2.8, so hardly use the manual lens anymore). Blurry pics are not a characteristic of this lens. Third, are you verifying focus with the little green dot in your viewfinder? IOW, does the camera agree that your shot is in focus before you shoot? Maybe what you are seeing is not the same as what the sensor is seeing, so see if the camera's internal focusing system (even with a manual lens) agrees that the shot is in focus. You could also put your camera in live mode so the image appears on the back screen before you shoot, then you can zoom in on that screen and adjust your focus. Live mode is a more accurate focusing method than the viewfinder because Live Mode is exactly the same thing that the sensor is seeing. I have no idea why your focus ring would move on a manual focus lens when you shoot, but JUST IN CASE make sure your camera body is switched to manual focus. Fourth, I suspect that your flash pictures are bright and blurry because you have manually set your aperture and shutter speed, but once the flash is turned on it might be overriding your manual shutter speed settings and reducing the shutter speed to 1/60th or 1/200th or whatever is the sync speed on your body. Also, is Auto-ISO turned on? It's so easy to activate that accidentally and it just wreaks havoc with flash pictures. Finally, I would set up some shot with a different lens, getting the focus, exposure, flash, ISO, and aperture correct. Once you are satisfied with your result, switch to the manual lens and use the exact same settings. That will tell you if something is wrong with the lens. It could be that your aperture blades are not closing properly on the new lens, so it's shooting wide open all the time. (The blades are supposed to close to the chosen aperture right when you snap the pic.) That would also explain overly bright pics and soft pics. Set the lens on f22 and use your finger to manipulate the little tab on the back of the lens to see if the blades close all the way down, or see if they feel sticky even if they do close. [/QUOTE]
