[QUOTE="gustafson, post: 503202, member: 40735"] Thanks for the awesome insights! As for the questions: - Yes, I've been using the green dot confirmation along with the viewfinder image, and they usually coincide. For very close-in shots, they can be a little off, and I've been going by what I see in the viewfinder. - As far as the M mode, I assumed it would inherently disable any automatic settings such as auto ISO. However, I will go back and check that I'm not inadvertently giving the camera control. There's no focus motor on the D3300, so I'm good there. As far as the focus ring moving, could it possibly be due to the camera changing the aperture when the shot is being taken, or due the closing of the shutter itself? - Great point on the effect of using flash on the shutter speed, even in manual mode. Will look into it. - The aperture blades seem to open and close OK, but I will double check. - Bob, thanks for the tip on the manual focusing screen, I have been thinking about it. Have you made the swap, and are there any downsides to it? Based on the inputs, one of my suspicions is that I may have not grasped the shallowness of the depth of field of this lens, and may be working way too near the close focusing limit where it is likely even shallower. Thus focusing may be very sensitive to movement on part of the subject or myself toward or away from the focusing plane. Am going to try stopping down to f8 or so and move further away from the subject to see if that gives me consistently sharper photos. I imagine there is a sweet spot for this lens in terms of aperture and subject distance where it is more idiot proof :) I'm attaching a few photos to show you some of the focusing issues, as well as the one photo where I seem to have gotten it right with the flash.[ATTACH=CONFIG]184786._xfImport[/ATTACH][ATTACH=CONFIG]184787._xfImport[/ATTACH][ATTACH=CONFIG]184788._xfImport[/ATTACH] [/QUOTE]
