You need to check exposure by shooting a blank wall as any other scene will not be as accurate due to reflectivity differences

I agee. I only have 2 DX lenses and they were given to me. I have a 50mm 1.4 FX and an 80-400 (older version without silent wave motor) FX lens. The DX lenses are a 10-24mm Tamron, an 18-70 Nikkor DX and a 70-300mm Nikkor DX lens. The 10-24 Tamron is limited because of two factors.. first is that at 10mm the optics tend to fisheye (unlike the Nikkor version) and a wide angle lens on a DX body is somewhat limiting due to the crop factor. In addition, the images from the Tamron lens (and I don't know if it is the manufacturer or the fact it is DX) seem flat andrequire quite a bit of massaging in post processing to get the image to look normal. This plus sharpness and detail are not as good as the images from my 50mm or the 80-400mm. Now, I don't have an FX wide to try on either the D610 (full frame) or the D7100 (DX) to compare so it could just be the fact it is wide angle or it could be the glass. As for the 18-70, it has similar results but slightly better. The 70-300 is okay but not great. It does (however) weigh about 1/4 of what the 80-400 weighs. Now, the 80-400 produces good rich shots that, generally are tack sharp. NOTE: the lens (as all but the Tamron) require the focus motor in the camera as all are older lenses. The 80-400mm is pretty slow to find focus but when it does it is right on the money. If I am shooting nature, I can keep it at near infinity and focus time is much improved. I can live with it. The newer version with the SWM focuses much faster.

True but I rarely shoot blank walls and I would rather have and trust two shots of the same REALISTIC image to compare. I have found that photos of blank walls are difficult to sell.
