I currently have a Sigma 50mm 1.4 Art which is by all means the best 50mm you can get for the price, only problem is that it's really heavy! So I've been looking at cheaper and slightly smaller AF 50mm alternatives. Since I also shoot Nikon and currently have a Nikon AF adapter (Commlite ENF-E1 PRO), I started researching Nikon mount lenses I could adapt. Recently I tried a Nikon 58mm 1.4 G and while it definitely has a unique look, $1700 USD is a bit too rich for my blood.

I remember Sigma did make a non-Art 50mm that was half the weight and also 1.4. I started looking at prices and saw that you could get used copies in the $200 USD plus range. Just for the heck of it, I started looking around and found a late model (smooth finish) Sigma 50mm 1.4 EX HSM for Nikon mount.

I received it this Friday and decided to take it for a spin. Mounted on the Sony A7III, it focuses quick and snappy. I've tried the Sony 50mm 1.8 FE and also the Nikon 50mm 1.8 G, but I wanted something a bit different and I think this Sigma delivers. I was initially considering selling my Sigma 50mm Art for something else, but these lenses actually render very differently. The Art is more technical and razor sharp, while the non-Art is a bit dreamy with smooth OOF rendering. In fact it feels more similar to Nikon's 58mm 1.4 G, but for a fraction of the price! :D

While I have the Nikon version, it's probably easier to get the Canon version and mount it with the MC-11 adapter, which from reports seem to be compatible with this lens! Anyways, I just wanted to post some initial samples for anyone who is interested in a cheap modern'ish 50mm 1.4 lens. I'll post more samples in this thread soon!

On a side note, this particular copy needs a major AF adjustment on my Nikon bodies. I've tried using my D750 live view to get a baseline focus, but strangely enough this lens is much sharper on the A7III despite using CDAF on both bodies. It's just a notch down from the 50mm Art, but still very good and at a reduced weight and size. Since I do plan to use this mainly on the Sony it's not that big of an issue, but I wish I could reach similar results on both platforms. Also the older Sigma 50mm non-Art is more like a 45mm so it does provide a wider FOV.

The results look almost similar to a Sigma Art lens at a fraction of the price! I'm still scratching my head why it's way sharper on a Sony body and more dreamy on a Nikon body? Definitely a testament to advantages of mirrorless with fast primes!

Anyways, I shot a couple shots from this weekend using the Sigma 50mm 1.4 EX and A7III. Though I wouldn't recommend this setup for streets due to being still pretty bulky, but I do find it a good setup for portrait work at a very affordable price versus going native!


A few shots at the Citadel Shopping Outlet and in the heart of cheesy Hollywood! Everything shot wide open just to test it out at all distances:

A couple more shots from today. I didn't even plan to shoot, but I bumped into a couple of my buddies in Pasadena and decided to hang out for a bit! I'll need to coordinate a photo shoot soon so I can test it out for it's intended purpose! :D

Hi there!

I have the same Sigma 50mm and I want to adapt it to an A7RII with an adapter. Do you have any idea if it could work, maybe with the same adapter? I've read that it doesn't work with well the a7rii and that I might have to do a Firmware update.

Thanks for any advice!

Hey there! Which mount is your Sigma 50mm? If it's Nikon mount, you can use the Commlite ENF-E1 PRO adapter. If it's Canon mount, you can use the Sigma MC-11 adapter. The lens should be fine, though either adapter might need the latest FW update.
