SongRaw AF 50mm f/1.2 FE Moonlit

The SongRaw CL1005 is a budget 50mm f/1.2 for Sony E-mount that delivers the shallow depth of field look at a fraction of the usual price. You'll deal with vignetting wide open, soft corners, and build quality that ranks dead last in our database. But if you love character lenses and don't need clinical perfection, it's a genuinely fun option. Just don't expect it to replace a Sony GM or Sigma Art for serious work.

The headline spec here is f/1.2, and that's what you're paying for. At that aperture, you get serious light gathering and a shallow depth of field that can melt backgrounds into creamy nothingness. The trade-off, as the lone reviewer points out, is noticeable vignetting wide open. That's not unusual for fast primes, even expensive ones, but it's more pronounced here. The lens uses 15 elements in 10 groups, including 2 aspherical elements, 4 ED elements, and 7 HR elements. That's a lot of glass for a budget lens, and it suggests SongRaw is at least trying to control aberrations.

The autofocus uses an STM motor with closed-loop monitoring, which should be decent for stills but maybe not the snappiest for fast action. Our data puts AF performance at the 54th percentile, so it's middle of the pack. Not going to embarrass itself, but not going to keep up with Sony's linear motors either. The minimum focusing distance is 0.52m with 0.13x magnification, which is pretty standard for a 50mm. Nothing exciting there. The real story is that f/1.2 aperture, and whether you're willing to accept soft corners and some character flaws to get it.

The competitors listed in our database are a strange bunch for a 50mm prime. You've got the Tamron 18-300mm, the Sigma 16-300mm, the Nikon 20059, the Panasonic Leica 12-35mm, and the Sony 18-135mm. None of these are direct competitors in the traditional sense. They're all zooms, and most of them are for APS-C or Micro Four Thirds. What they share with the SongRaw is a budget-friendly price point and a focus on versatility over raw optical perfection.

If you're cross-shopping the SongRaw against something like the Sony E 18-135mm f/3.5-5.6 OSS, you're making a fundamental choice. The Sony gives you a huge focal range, optical stabilization, and reliable autofocus, but you're stuck at f/3.5-5.6. The SongRaw gives you f/1.2 and a fixed 50mm focal length, but no stabilization and questionable build quality. For portraits and low light, the SongRaw wins on paper. For travel and everyday shooting, the Sony zoom is way more practical. The Tamron and Sigma superzooms are even more extreme in that direction. They're Swiss Army knives. The SongRaw is a very specific tool for a very specific look.

Value is hard to assess here because we don't have a confirmed price for this lens, which makes a proper price-to-performance analysis difficult. But the entire pitch from SongRaw, and the entire reason the one reviewer bought it, is that it's cheap for an f/1.2. The reviewer literally says "at this price for f/1.2, it's a buy." That's the whole value proposition. You're not getting Sony GM or Sigma Art level optics. You're getting a lens that opens up to f/1.2 and lets you play with that look for what we assume is a fraction of the cost.

Compared to the Sony FE 50mm f/1.2 GM, which runs well over $1,500, or even the Sigma 50mm f/1.2 DG DN Art, this thing is in a completely different price bracket. The trade-off is that you're getting 1st percentile build quality and bokeh. If you're the kind of shooter who treats lenses carefully and doesn't mind some optical character, the value could be real. If you need clinical sharpness and reliable autofocus for paid work, you'll probably end up buying the Sony or Sigma anyway, which means you've spent twice.

The SongRaw CL1005 is a weird one, and we mean that in the most interesting way possible. It's a 50mm f/1.2 autofocus lens for Sony E-mount that costs a fraction of what Sony or Sigma charge for similar glass. On paper, that's a screaming deal. In practice, you're getting a lens with some serious character quirks and a spec sheet that reads like it was translated through three languages and a game of telephone. The max aperture is listed as f/50 and the min aperture as f/1.2, which is backwards, and the weight is listed at 1878g, which would make this one of the heaviest 50mm primes ever made. We're pretty sure that's a typo, but we can't verify it without a scale in hand.

Who is this for? Honestly, it's for the tinkerer. The person who loves old lenses with weird rendering, who doesn't mind some vignetting wide open, and who wants that f/1.2 look without selling a kidney. The one customer review we found, written in Japanese, says exactly that. The buyer notes there's peripheral light falloff wide open, but at this price for f/1.2, it's a buy. They even say it's replaced their Zeiss Planar T* FE 50mm f/1.4 ZA as their main lens. That's high praise from someone who clearly knows their glass.

But let's be real about the data. Our database puts this lens in the 1st percentile for build quality and bokeh, and the 2nd percentile for aperture performance. That sounds brutal, but it's also comparing a budget Chinese lens against every premium option on the market. The optical score lands in the 18th percentile, which means it's not going to win any sharpness contests. What it does offer is a genuine f/1.2 aperture on full-frame for a price that makes the compromises easier to swallow.

Skip this lens if you shoot weddings, events, or anything where you can't afford to miss focus or have a lens fail. The average autofocus and questionable build quality make it a risky choice for paid work. You'd be better off with a used Sony FE 50mm f/1.8 or saving for the Sigma 50mm f/1.4 DG DN Art, which offers much better optical performance and reliability.

Also skip it if you need weather sealing or shoot in harsh conditions. There's no sealing here, and the 1st percentile build score suggests this lens won't take abuse well. If you're a landscape or travel photographer who needs a lens that can handle rain, dust, and the occasional bump, look at the Sony E 18-135mm f/3.5-5.6 OSS or the Tamron 18-300mm instead. They're slower, but they'll survive the trip.

If you're a portrait shooter on a tight budget who wants that f/1.2 background melt and doesn't mind some vignetting and softness in the corners, the SongRaw CL1005 is genuinely interesting. The one real review we found suggests it can hold its own against much more expensive glass if you're willing to embrace its quirks. The fact that it replaced a Zeiss Planar as someone's main lens is not nothing.

But if you need a lens for paid work, fast action, or anything where reliability matters, this probably isn't it. The 1st percentile build quality and bokeh scores are red flags. No weather sealing, no stabilization, and an autofocus system that's just average. You'd be better off saving for a used Sony 50mm f/1.8 or stretching to the Sigma 50mm f/1.4 DG DN Art. The SongRaw is a fun second lens, not a dependable workhorse.
