I've recently got a Nikon D850 and I'm having an issue with the edges being soft. Wherever I'm focusing is fine but as I look at the right and left sides it gets softer. Is that normal or is there something I'm doing wrong? I'm using a Nikkor 24-70mm lens (without vr), a tripod and a remote shutter.
Sound advice from David. These hi-rez cameras let us see everything more clearly. The 24-70 is supposed to be a good lens, but maybe not good enough for the latest camera? At any rate, I would expect the prints to be pretty good. Lenses are getting larger, heavier, and more expensive with some good reasons.
is this a full frame or a crop? the full may expose the fact that the edge were never used in the cropped sensor and your seeing it now. lenses have sweet spots, the edges often suffer if its a cheap lens. as said try different F stops, it usually has a sweet point where the number makes everything in focus. do you have any examples?
Soft? Or just slightly not as sharp? Just at the WIDE end or throughout the lens range? ALL telephoto lens will suffer at some point, compared to prime lenses and even those can have issues, regardless of the cost!
What I tell my students that have issues, is this. Set up your camera and tripod AND cable release and also MIRROR LOCK-UP and then using a wall or garage door, tape either a newspaper or cardboard that has nice fine fonts and copy that, at different ranges and F-stops, of your camera. Then look for some consistent "softness" in the ranges of 24-70. You don't have to use every single MM, just the ones you usually use, wide, 50mm and then 70.
If you find some real issues, you might be able to return the lens. If not, the simplest "fix" is to shoot a bit wider and then crop that edge out!
Silly question, but have you looked at the back of the lens and made sure there is now oil/smudge/fingerprints there?
If the lens is kinda newish, maybe contact Nikon and see what they have to say. Might have a bunch of these lenses that have issues and will replace it. If this is a cheap plastic "kit" lens, then probably not.....
Have you had the sensor cleaned recently, maybe debris on the sides?
Maybe time to look on eBay for a new OLD lens.....
oh yeah that happened to me the first time, the back of the lens was covered in filth and everything looked bad. once cleaned, it was much better. it was practically fogged over, and it was a new lens.
i've heard of cameras in the past where the cmos wasn't totally seated flat, and was tilted. and everything was oddly blurred.
I've read your opening several times and maybe I'm missing something but it isn't clear to me if you're viewing the image after capture or through the eyepiece. So, taking nothing for granted, if it's viewing before capture, make sure the eye piece is also clean and focused for your eyesight.
I have the D850 as well. I don't have that lens, but I find my Tamron 24-70 G2 does fairly well corner to corner stopped down to f11. The D850 is VERY revealing of all flaws, however, so if you have a bum lens, you'll see it for sure.
Rich, I hadn't locked up the mirror and once I did that it seemed to fix whatever issue the lens/camera was having. Thanks for the help.
Brian it was after I had taken the image and viewed it on the review screen and in lightroom.
Thanks everyone for the help!!!
@Rich - The edges are bound to be inferior to some degree relative to the center of the lens. Nikon cameras have a micro-adjustment feature for each body-lens combination. The basic idea is that while one body may be within acceptable specs, and a lens likewise within a range of acceptable specs, the combination may not, resulting in slight back or forward focusing. It seems plausible to me that a slightly off lens might look acceptable in the center, but not at the edges. So there's a procedure for using a test image (commercially available, but I use a printed fractal pattern with high contrast) to make sure each of my lenses is properly calibrated to each body.
All that said, as Rick mentioned above, the D850 will reveal flaws that would not be seen with a significantly smaller megapixel camera. I almost invariably use a tripod with the mirror locked up and a remote shutter release, unless I'm moving around. When shooting handheld, the D850 pretty much requires a shorter exposure than a lower megapixel camera.
