After five copies over 12 months, I finally got a working Sigma 30mm f/1.4 for my Nikon mount. It is a real gem, if you can find one that actually works. Sigma’s got some quality control issues on this lens. I’m now hesitant to look for any more Sigma products!

Lens #1: Massive focusing issues near infinity, but close-up focusing was fine

Lens #2: More focusing issues at infinity

Lens #3: Misaligned aperature blades– blades came together to form a lopsided, irregular-shaped aperture

Lens #4: Very squeaky HSM (AF-S) motor

Lens #5: Finally, a good copy!

Is it better than the Nikon 35mm f/2? Yes!

Is it worth getting if you have the Nikkor already? No.

Would I recommend buying the Sigma? Maybe… Pick one up in-store, and try out the lens at the store. Make sure

1. Focusing motor doesn’t squeak

2. Aperture blades make a “regular” shape when the lens stopped down

3. Near focus as well as far (infinity) focus is calibrated correctly.

Don’t be willing to settle for “just buy it and send it in to Sigma for adjustment.” The lens should be perfect out of the box! This is an outstanding low-light lens that has developed a horrendous quality-control reputation. Shame on Sigma!

Now, someone please make a wide-angle prime optimized for APC-C/DX sensors! I’ll take a 12mm or 14mm f/2.8 one, please…
