To add to the point above: it might be worth being a bit careful before you commit to just one focal length. There was this one time a few years back when I first got serious about portraits... I bought a long prime thinking it was the holy grail, then realized I couldn't back up far enough in small rooms. If you're shooting couples in a studio, the Sigma 85mm f/1.4 DG DN Art might feel a bit tight. That one session I spent literally pressed against a wall trying to frame a wide shot was super awkward. You might want to consider the Sigma 50mm f/1.4 DG DN Art instead if you need more versatility. It handles distortion well for faces but gives you that extra space for full-body shots without needing a massive studio. Also, make sure to be mindful of the weight. Something like the Sigma 105mm f/1.4 DG HSM Art produces incredible images but it's a heavy beast. If you're shooting handheld for hours outdoors, your arms are gonna feel it... dont say I didn't warn you lol. Just check your typical working distance before you drop the cash.

ShadowPulseX hit the nail on the head there. Honestly, I had a pretty disappointing experience when I first started out because I ignored that exact advice. I saved up for months to get this super high-end, long focal length lens that everyone online was raving about for perfect bokeh. Unfortunately, it was a total waste for my specific situation. My studio at the time was basically a converted spare bedroom, and I quickly realized I couldnt even fit a couple in the frame without standing in the hallway... it was super awkward. The images were sharp, sure, but the lack of flexibility made it nearly useless for my indoor gigs. I ended up losing money when I traded it in for something wider that actually fit my room. It taught me a hard lesson about not just buying what people say is best on paper. Definitely measure your space before you blow your budget like I did, cuz pricey gear doesnt mean much if you cant actually move around your subject.

I've had great success with the Sigma 85mm f/1.4 DG DN Art lens for portraits. The large aperture allows you to create a beautiful bokeh effect and achieve a shallow depth of field to really make your subject pop. The image quality is also superb, with excellent sharpness and color rendition. I'd highly recommend this lens for anyone looking for a high-performance portrait lens.
