Having a problem with a lens on my D850, Need advice
May 3, 2024 16:00:58 #
Hello fellow Hoggers,
I am shooting high school sports action photography. i am shooting with two different lenses on my Nikon D850. Both are Tamron lenses. I shoot in shutter priority mode @ 1/1000 second and I let the ISO and aperture float. When I shoot with my Tamron SP 150-600 my exposures are spot on. When I shoot with mt Tamron LD 28-200 I find my exposures are too dark and I must compensate by adding 1 and 3/4 stop of exposure compensation. Nothing else is changed. Can anyone advise as to why I am having this problem? I tested the lenes after the shoot and found the problem persists. Is there some setting I am missing? All advise, as always, is appreciated.

Did you test and compare the lenses with every last vestige of AE disabled ? You hafta start from ground zero to find out whatz up.
Assuming that via the above you prove that the lenses are equally bright at wide, mid and small apertures, then its time to compare the exif data. And if you have access to one more Nikon then check whether the same problem occurs with the other camera.
Acoarst there are many variables but thaz enuf to get started. No point right now in writing a miles long presentation of all the possibilities (but the UHH geeks will do that anywho). Start with the basics, as above.

What is the maximum aperture available on your 28-200 vs. on the 150-600 at the focal lengths you are shooting with each?
I suspect that you may have an upper ISO limit set that will not allow your camera to achieve proper exposure with the superzoom. Or your camera may for some reason not be properly recognizing the 28-200. Do you have the most current firmware loaded? It's also possible that your lens may need a firmware update.

I'm not familiar with your lenses. I also have a D850. I solved a similar peculiar problem. I tend to use aperture priority, so the situation isn't exactly the same, but one particular Nikon lens of mine consistently underexposed by 1/2 to a full stop compared with my other lenses. It has an aperture ring. When I let the camera choose the aperture, it underexposed. When I set the camera to allow me to use the aperture ring to set the aperture, the problem was no longer present. Your camera is obviously setting the aperture. Perhaps the lens is miscalibrated, but one thing you can do (if possible) is compare exposure on a different camera and see what happens. If the problem persists, then the problem is in the lens.

First thing I would do is change you exposure mode to one AE function being variable.

Let the ISO and aperture float and shoot in M mode with both lens and see of the results are the same.

Not even. Shoot in manual with auto ISO. Choose the shutter speed & aperture & let the iso float. If setting a max iso (eg. 3200) & the photo is underexposed, the iso most likely maxed out.

I agree with Larry. Please check all of the settings in Auto ISO to make sure that there is nothing to prevent the ISO from reaching the needed max number. On my D850 I am usually in Aperture priority with Auto ISO or Manual with Auto ISO. When in Manual with ISO I set the shutter speed on the camera by turning the command dial on the right side of the camera. When I use Auto ISO my max ISO setting is the max ISO the camera can reach.

Exactly what I use and it always works with any lens. I set the max ISO to 6400 so in dark areas I do need to adjust the EV.

Perhaps I am not completely understanding the situation, but, generally speaking, the first rule of troubleshooting a system is to remove as many variables as possible.
That would preclude Auto ANYTHING. Put the camera on a tripod on a bright sun shiny day. (So you know the proper exposure should be "sunny 16" . Same subject 2 different lenses. See if you can replicate the problem.
You can of course then try various auto modes or anything else you want, but add one variable at a time.
Keep notes, because if something needs to be repaired you can send examples.
Good luck

I can't help but wonder about the exposure area you have selected. Is it center point, center weighted or overall average. When using the 150-600 you are most likely zoomed out creating a smaller evaluated for exposure even if an overall average is selected. The 28-200 will naturally average a wider area possibly picking up stands and darker area of the field or court. First check the exposure area. If this isn't the cause,I suggest setting up a static shot adjusting the zoom setting to the same mm with each lens either 175 or 200 mm keeping all other variables the same for both lenses. As mentioned previously you may need to use exposure compensation when using one of the lenses.

Thank you all for your replies, (with the possible exception of RETIRED CPO), I am in the process of testing now and will update you all with the results.
