I'm a newbie who spends most of the time taking portrait pics of the family both indoors and outdoors.
My camera is a D80 with a 18 - 135mm lens
I was considering getting a prime lens for low light indoor photos and was hoping to get some advise.
I knwo the Sigma 30mm F1.4 EX DC HSM is a good lens but I feel it may be an over kill for a newbie?
Alternatives could be a 2nd hand Nikon 50mm F2.0?
Do you think a newbie will be able to tell the diff between an F1.4, 1.8 and 2.0?
Should I just go with a cheap 2nd hand lens 1st?
Also I saw a thread saying that 50mm prime lenses are the most common, but with the crop factor a 30mm lens becomes nearly 50mm, so why arent people buying these?
What would you recommend?
