When starting photography the first thing you think about is what camera to get! (aside from actually knowing how to use it). I always get asked why I chose Nikon over Canon, simply put- its all about the dynamic range. I did lots of research and came to the conclusion that with my editing style that is all that really mattered! (more info on that here).
I am not going to get into how much I love Nikon and how Canon is terrible, because its not! Both systems are just tools in the hands of a creative. I didn't start photography to drool over gear, however knowing what a specific lens to use is very crucial in creating a specific look or feel to your photos in a given situation.
Heres a list of my gear below and a little bit about what I use each lens for.
2 Nikon D750 Cameras | Why D750 and not D810? mostly because of the flip screen ;)...and I really don't need OR want the huge file sizes of the D810.
Nikon 70-200mm 2.8 lens | Used mostly for a couple ceremony shots, rarely do I take it out for portrait shots. Its the most heaviest lens and barely gets used if at all! Why do I have it?! Pretty much for emergencies, example: We were shooting a catholic wedding in a church and found out that we are only allowed to shoot from the back or the balcony and could not use flash. Yay, right?! So this lens at 2.8 and the zoom range came in handy and saved the day!
Nikon 24-70mm 2.8 lens | This was my first big investment into gear. I was still learning about photography - wedding photography specifically, and everywhere I researched it said this was the must have lens if you want to shoot weddings. So of course I had to buy it! and I am so glad I did, this lens is so versatile and is perfect for any portrait session or event that if I had to shoot with only one lens forever - this would be it.
Sigma Art 50mm 1.4 lens | For getting ready shots and portraits
Sigma Art 85mm 1.4 lens | For when I want a more tight or close up photo of the model or couple.
Sigma Art 35mm 1.4 lens | This is my all time favorite lens! because of its photo journalistic feel I used 90% of the time in any portrait session and during the wedding day.
Back up gear: Nikon D750 Camera depending on who is assisting me, they wear my backup gear just in case I have to grab and go.
+ lots of flashes, batteries, gadgets, light modifiers, and memory cards. Plus backup of all that.
There is so much I can say about gear, and I can talk about it for hours, its always fun to see, compare, and get excited about! I mean, have you seen an 85mm shot at 1.4? I mean dreamy bokeh hallo! ;)
Overall, the best advice I can give is to not focus too much on the gear when shooting, as long as you capture (properly) the precious moments for your clients, thats all that matters.
Let me know if this has been helpful and what kind of gear you prefer to shoot with.
