I would suggest being careful with the 105mm because its a total brick. Honestly, your wrist will feel it.

• Sigma 85mm f1.4 DG HSM Art for Canon EF: Best bet. It fits the budget and stays sharp wide open.
• Sigma 105mm f1.4 DG HSM Art for Canon EF: Amazing bokeh but way too heavy. Make sure to get the Sigma USB Dock for Canon EF tho, those Arts sometimes need focus tweaks.

Just saw this thread and had to jump in! Re: "I would suggest being careful with the 105mm..." - man, that weight is no joke! I did a huge outdoor wedding last summer and by hour eight, my forearms were shaking like crazy. I remember the first time I pulled my files into Lightroom after switching my main kit to those heavy Art primes... the level of detail was actually terrifying! I could see individual eyelashes from across the room. I used to obsess over the MTF charts and the chromatic aberration data before making the jump, and the real-world results actually lived up to the hype for once. A few things that really helped me out:

• Spending a Sunday afternoon with the Sigma USB Dock for Canon EF to fine-tune the AF points for my specific body.
• Swapping to a heavy-duty dual harness to handle the extra glass weight.
• Updating the firmware immediately to fix some weird pulsing issues I had in low light. It was such a relief to finally trust my gear again during those high-pressure ceremony moments. Having that tack-sharp focus at f/1.4 completely changed how I frame my shots now... honestly, the resolving power is just on another level compared to the older stuff I was using! Once I got the micro-adjustments dialed in, my keepers went through the roof.
