I find that when I shoot interior shots with a Sigma 10-20mm lens on my Nikon D7200, I get a lot of flare (or at least that's what it looks like to me). The images are just not as crisp as I would like them to be. Attached are some examples. I did some work on these images to improve them in Photoshop but they are still not what I want. f-stop? shutter speed? ISO? Any suggestions would be appreciated. My exterior shots are nice and crisp when using the same lens.
Hi Bob,
I don't think it is flare, or if it is, it is extremely mild. The scene in that house is intrinsically low contrast what with white walls, white cabinets, a light colored floor and stainless steel appliances. If there is a slight lack of contrast due to mild flare, it may be caused by ypur shooting into or against a bright light source such as the day-lighted window in the kitchen and the vanity lights in the bathroom.
If a protective filter was used, sometimes that can bring on a bit more flare.
Serious flare usually shows up as very visible and oftentimes colorful interference caused by light striking, not only the front surface of the lens, but reflecting from other elements and surfaces within the lens. It would be very apparent around the light sources like that window or the fixtures in the washroom.
A good test would be to shoot something in a similar location with the same lens and another lens, preferably a prime lens, even if it is not a wide. This would reveal if there is any defisit in the lens. Oftentimes zoom do not perform as well as primes but I don't see an extreme issue.
In the exterior shot, there as a more colorful and contrasty scene and there are no bright light sources in the image.
I am working away from my studio but I did a quick edit on my smart phone- I will post it with your permission. A slight boost in contrast and saturation and a little burning, jazzed it up nicely.
Let me know.

The Sigma 10-20 flares horribly. I gave mine up for a Sigma 8-16, which is MUCH better in situations such as yours.
Tripod, tripod, tripod! Regardless of lens your not going to get crisp images at 1/8 second and f11 without a good tripod (the first image.) So bring in a good stable tripod and open the lens up to f8. Your not going to get maximum sharpness from a crop sensor at anything above f8.
Sigma lenses are generally quality lenses. And you have a very good crop sensor camera. D7200. I wonder if you would have had the same results, had the interior walls been darker in color?
Both the Sigma 10 - 20 & 8 - 16mm are prone to flare, although the 8 - 16 less so. Flare will show up mainly when phographing idarker interior rooms with bright windows. A tripod is of course needed indoors but has no effect on flare. Best to shoot the window from two different angles. Flare can be removed often in Photoshop.
As to sharpness is best indoors to use the hypofocal distance and switch to manual focus. The hypofocal point is just before the infinity mark on the lens but is not marked. Try some test shots moving the focus from after the infinity mark, on the mark, and just after it. On your computer zoom to 100% to check focus.
F11 will give better fucus, near and far, but f8 a sharper image. Your choice. You may get less flare at f8. Some testing required to find the setting you like.

Have you tried a lens hood?
It appear that the light coming on from the windows might be too bright. The lights in the bathroom appears washed out/too bright. Try taking the same photos using a flash to compensate for the bright lights
