I am actually so done with my current setup right now it is driving me crazy. I have been using the Sony 85mm 1.8 for a while but lately the autofocus has just been straight up gaslighting me and I keep getting these weirdly nervous backgrounds that just look cheap. Honestly I am so fed up because I have a huge wedding shoot coming up in Seattle in three weeks and if I don't get this sorted I'm going to have a panic attack on the day of. I need something that is actually reliable and sharp but mostly I just need that creamy Sigma look that everyone keeps posting on Instagram.
My budget is strictly under $1200 because I am broke after buying new bodies and I really can't afford the Sony G-Master tax right now. I have been looking at the Sigma 85mm 1.4 DG DN Art but then I see people talking about the 105mm 1.4 and how it is the bokeh master but that thing looks like a literal brick and I dont know if my wrists can handle an 8 hour day with that much weight. Is the 85mm Art fast enough for moving subjects like a bride walking down the aisle or am I gonna run into the same hunting issues I have now?
I've also heard some people mention the 65mm or even the 90mm but I feel like those might be too niche for what I need. I just want one lens that I can stick on my A7IV and leave it there for the whole portrait session without worrying that half the shots are gonna be slightly soft. Which Sigma is actually the best for professional portraits right now because I am losing my mind trying to decide...
Honestly, I totally feel your pain with that Sony 1.8. It is a decent entry lens but the bokeh is super busy and the autofocus misses just enough to make you paranoid during a big event like a wedding. Unfortunately, I have had some pretty bad luck with some of the older Sigma designs lately. People rave about them constantly online, but in real-world scenarios under high pressure, they really are not as good as expected when it comes to consistency. I once tried to muscle through a long ceremony with a massive prime that weighed a ton and my wrist was basically dead by the reception. You really need to be careful about that weight factor because fatigue makes your shots worse than any lens defect would. One major warning I have to give is that while the Art series produces gorgeous images, some of the older adapted versions are a total nightmare on the A7IV. The autofocus tends to pulse or hunt in backlit situations which is exactly what you dont want when a bride is walking down the aisle. If you get that pulsing effect, you are gonna lose the moment. I would stay away from those niche 65mm or 90mm options for professional work too. They just dont have the same presence for high-end portraits. Stick to the mirrorless-native designs, otherwise you are just trading one headache for another.
