[QUOTE="Horoscope Fish, post: 474827, member: 13090"] Okay, that's actually good because shooting that wide and that slow is one of THE BEST ways I can think of to get soft, out-of-focus shots. One of the best things you can do to help get consistently sharp shots is keeping the shutter speed at twice the focal length you're shooting at. For instance, if you're shooting at 35mm, you want your shutter speed at 1/70 or above. If you are shooting at 100mm you want your shutter speed at no less than 1/200. In order to make this happen you may need to increase your ISO. That's fine, digital noise is easily corrected for in post, an out of focus shot is pretty much a lost cause. 1/80 probably had you in a pretty safe zone, but anything slower and yeah, I'd expect some soft shots. And the depth of field at f/1.4 is going to be pretty much razor thin. Now, if you want to fine tune the Auto-focus of your camera you're going to need get scientific on this. AF Fine Tuning means making very minute adjustments and this is no place for hand held shots in crappy light. There are numerous ways to check to for front/back focus issues but I'd suggest you start by reading [url=https://nikoneurope-en.custhelp.com/app/answers/detail/a_id/51633/~/how-to-use-the-af-fine-tune-function]How to Use the AF Fine Tune Function[/url].
