Im in a total bind right now because I have a wedding shoot coming up in three weeks and my current glass just isnt cutting it on my new S5II. Ive been obsessing over forums and reviews for days and honestly Im more confused than when I started. People keep pointing to the Sigma 85mm f1.4 DG DN as the absolute gold standard for sharpness but then I see others swearing that the Panasonic S PRO 50mm f1.4 is significantly better for skin tones and contrast across the frame. I dont know what to believe anymore and I really need to get this sorted before my next rental window closes.
Here is what I need to hit:
- Budget is around 1200 dollars max, maybe a bit more if its used.
- Primarily doing portraiture and candid work so autofocus speed actually matters as much as the sharpness.
- Needs to hold up at f1.4 because thats where I spend 90 percent of my time.
- Size matters but honestly if the image quality is crisp enough I dont care if its a brick.
Is there a clear winner here or am I just splitting hairs between these two? Im starting to panic a bit because I cant afford to waste money on a lens that doesnt look surgical at 100 percent crop. Does anyone have real world experience with either of these?
Honestly, skip the stress. I have used the Sigma 85mm f1.4 DG DN Art for ages and it is surgical. It stays tack sharp wide open, which is exactly where you want to be. The AF speed is plenty fast for candids too. You wont regret grabbing one, it basically lives on my body for portraits. Honestly, its a steal for the price point.
@Reply #2 - good point! Honestly, both those lenses are fantastic, but you should also check out the Sigma 35mm f1.4 DG DN Art. I shot a wedding last month and it never left my body. It is surgical sharp wide open and gives you that extra bit of space for candids.
- Way cheaper than the S Pro
- AF is super snappy
- Feels balanced on the S5II Save the cash for a solid SanDisk Extreme PRO 128GB SDXC UHS-I card.
To add to the point above: you are definitely splitting hairs here. Both are top tier, but the Panasonic Lumix S PRO 50mm f/1.4 gives that specific rendering Panasonic users love. If you are worried about surgical sharpness, maybe look at the MTF charts on LensTip. They have objective data that might calm your nerves.
- The Sigma is definitely sharper in the corners, but the S PRO has way less onion-ring bokeh.
- AF reliability on the S5II is solid with both, just make sure you update your firmware to the latest version. Honestly, if you have a wedding, rent both for a day. It is way cheaper than buying the wrong one and regretting it during editing. If you cant do that, just grab the Sigma and spend the extra cash on a solid SanDisk Extreme Pro 128GB SDXC UHS-II card so you dont have any buffer issues.
