So I finally upgraded to a Sony A7IV and I'm looking to get a dedicated portrait lens because the kit lens is just not doing it for me especially for low light stuff. I have my sisters engagement shoot coming up in like three weeks at a park near Seattle so I need something fast and reliable. I'm really torn between the Sony 85mm f1.8 and the Sigma 85mm f1.4 DG DN Art.
The Sony is way cheaper and lighter which is nice for hiking to the spot but that Sigma bokeh looks so creamy in all the reviews Ive seen online. I'm also slightly considering the 50mm f1.2 GM but honestly thats probably overkill for my budget right now which is strictly under $1100. I mainly want that sharp eye autofocus performance because I dont want to miss any shots when they are moving around. The Sigma is right at the top of my budget but the weight is kind of a concern for me if I'm walking around all day. On the other hand is the f1.8 on the Sony enough for that really blurry background look or am I gonna regret not getting the faster glass? Which one would you guys pick for a rainy outdoor shoot?
