Question by Star: Changing the aperture on my dslr?
I have a Nikon d3200 and recently got a Sigma 75-300mm lense When I attach it to my camera it will only work in manual mode which is fine…but I dont know if that is normal?? Also when it is attached to my camera it wont let me change the aperture. Yes i did hold down the exposure compensation button and turn the command dial at the same time and it is not doing anything. Please help. I need to change the aperture my pictures are turning out way too dark. Also my flash will not work with the larger lense.

I am not familiar with this specific lens, but I do know that when you use older Nikon lenses, you need to lock the aperture on the smallest aperture (largest number) to make them work with the command dial. Take a look at this picture and read the caption. Look for anything on your Sigma lens that might do the same thing.
