Sigma 50mm f/2.8 EX DG Macro 50mm

If you want a cheap macro lens that's brutally sharp where it matters, this Sigma is a steal. Just don't expect it to do anything else well, especially if you care about bokeh and autofocus.

What surprised us most wasn't the macro sharpness, which is exactly as good as the 83rd percentile ranking suggests, but the bokeh. Despite what a bunch of glowing user reviews claim, our test database puts its bokeh quality in the 3rd percentile. That's dead last for any 50mm we've tested. So if you're expecting creamy backgrounds for portraits, you'll be disappointed. On the bright side, at macro distances the depth of field is so razor-thin that the harsh background rendering doesn't matter much. Autofocus is another head-scratcher. It works, but it's noisy and hunts more than a bloodhound in low light. For static subjects on a tripod, it's fine. For anything moving, it's a struggle.

The closest modern alternative for Nikon DSLR shooters is the Nikon AF-S 50mm f/1.8G. It's cheaper, faster, quieter, and delivers way smoother bokeh, but it can't do 1:1 macro. If you need macro magnification on a budget, this Sigma is the obvious pick. For those with a bit more cash, the Tamron SP 90mm f/2.8 Di Macro offers a longer working distance, optical stabilization, and much better autofocus, and it's a far more versatile lens overall.

Prices jump around by as much as $117 depending on where you shop, so check a few retailers before clicking buy. At the lower end of that spread, this lens is a genuine bargain for a dedicated macro shooter. But if macro isn't your main mission, that money is better spent on a faster 50mm prime that handles more situations gracefully.

Here's the one thing to know: the Sigma 50mm f/2.8 EX DG Macro is a razor-sharp macro specialist that's an absolute steal if you can live with its rough edges. It delivers true 1:1 magnification without tubes or adapters, and the detail it pulls out of flowers, bugs, and product shots is genuinely impressive. But step outside its macro comfort zone, and the flaws pile up fast. The autofocus is slow and sounds like a toy robot, the bokeh is surprisingly harsh, and there's zero weather sealing. It's a lens with a single superpower and a lot of kryptonite.

If you're after a versatile prime with gorgeous bokeh and snappy autofocus, this isn't it. Go get the Nikon 50mm f/1.8G instead. This Sigma is a specialist that only makes sense if macro is your main obsession.

The Sigma 50mm f/2.8 EX DG Macro is a single-minded tool that excels at one thing: detailed close-ups. If that's all you need, it's a fantastic value and one of the sharpest budget macros around. But its poor bokeh, sluggish autofocus, and lack of weather sealing make it a frustrating companion for anything else. For most people, a more modern macro or a faster prime is the smarter play. But if you're building a budget macro rig for product photography or flower close-ups, this old Sigma delivers where it counts.
