Message: <blockquote data-quote="lars jones" data-source="post: 487138" data-attributes="member: 40501">I've now shot about 3000 images with my d7100 and I'm really, really disappointed with the focus -- auto AND manual. I expect super sharp, crisp imaging from Nikon, but I have to say my iphone does a much better and more consistent job. Perhaps there's something wrong with my camera or lenses (new)? I see from this forum I'm not the only person who suspects a focus problem but nowhere do I see any answers. If I can't get good crisp images on this camera, there's no reason to buy other nikkor lenses or nikon cameras. I know it's possible, but I'm not getting them and I can't understand why. I've shot professionally when I was younger so I know exactly what I'm doing. I've tried viewing them on my laptop (about 1400x800), my iphone6+, and my HD TV and the results are the same, the focus is crap.1. I'd estimate only about 10%-20% of my images are acceptably focused (with my iphone that's about 80-90%). That alone suggests a problem with a camera or lens. I'm see the focus issues with both lenses that came with the camera kit (the 18-140 and the 50-300 nikkor lenses) but it seems more so with the 18-140.2. Using "view nx2" software to show the focus points indicates that on autofocus, it just ain't focused. I'm not moving, the subject's not moving, the shutter speed is 1/250, VR is on, all the switches and settings are good.... it's just not focused. It's close, but it looks like I'm shooting through a film of vaseline. so frustrating. These images aren't good enough to publish on-line....3. Trying manual focus, and refocusing after every shot, just gives unfocused results as well. Whatever looks dead-on in the viewfinder downloads as out of focus too. argh!4. I used two real world tests: A) I shot blades of grass in the bright sunlight. Both lens, manual or autofocus, seem to pass until I start to increase magnification; even at 0.5 it's not acceptable. Again, the 50-300 is better, but still not acceptably sharp. Test B) shooting spiders in their webs --- I've yet to see an autofocus camera pass this test. Predictably, the D7100 failed miserably. Sadly it also failed miserably on manual too. 5. Can I get a 45-degree split prism viewfinder (like the old F2s used to have)? Then I could be absolutely sure the focus is dead on. At this point, I'm seriously thinking about sending it in under warranty. Does anyone have any suggestions???</blockquote>
