I'm shooting a indoor wedding for a good friend in next month in October. I normally don't do weddings, but the couple are unable to afford a photographer otherwise so I agreed to do it for them. I have photographed weddings in the past but not as the professional photographer more as a guest or back-up. I have a Nikon D5300 with a 18-55mm kit lens, 35mm 1.8, 50mm 1.8, 55-300mm 4.5. I know I have the portraits covered with my primes, but I'm wanting a budget friendly zoom lens for the ceremony itself. I tried out my 55-300mm at the last wedding I attend and it worked ok, although a bit slow in the low light and seemed almost too much. I would like more of a mid-range zoom if possible. I do attend a lot of weddings or gatherings it seems so I'm sure it whatever I get would get used quite a bit. Any suggestions on a good zoom or budget friendly lens? Thanks in advance everyone.
