p.1 #1 · p.1 #1 · Super Cheap Laowa 15mm f4 Macro clone..


Some of you may have seen that there's an Opteka 15mm f4 macro available, down to USD 149 from Amazon or eBay (usually from circuit city)

Laowa published a warning about this as a "shoddy copy" with no serial no etc. They say that they never sell their lenses under any brand other than their own.

Well it's so cheap, no more than a good set of extension tubes, which in any case will be too long for a really wide lens, that I decided to pick one up.

Well I don't believe Laowa's claim that it's a copy. I believe the simplified housing is a copy (it's basically the same but without the shift mechanism) and that housing is put together a bit agriculturally.

But it's exactly the same optical formula, complete with aspheric, UHD elements etc etc. And the optical performance reflects this: almost no LoCa at close distances, surprisingly sharp etc.

Now people who clone designs do not clone such complicated ones (yet, anyway). And why would you go to the huge investment required to clone a complicated lens which is so niche, and then sell for 149?

So I have no idea what happened. If I had to guess, I'd say the factory that makes the Laowas sold off extra production of the optical core, or that Laowa had excess stock they sold off in bulk.

In any case it's fine (the focussing scale is completely wrong, as sometimes happens on Samyang lenses, but a bit of disassembly can fix that if you really care)

And even the relatively inexpensive Laowa is a bit much for something as niche as an ultra wide macro, even for me who does a bit of macro. But 149? Just buy it. And it doubles as a pretty OK 15mm lens at infinity, if you don't have one.

Here's a quick test image somewhere between 1:2 an 1:1 (the flower is less than a quarter of an inch across)

I saw this today, and looked it up to see if I could find any info. According to a RED camera forum, it performed almost identically to the Laowa, aside from not having access to shift. This seems like an incredibly inexpensive way to get a neat lens.

There is a lot of money going into research and development and lens designs should not be 100% cloned.
Venus is already in legal proceedings with this manufacturer in China.

Yes I had heard that; but my guess (which could be mistaken) is that it isn't strictly cloned. R&D is not free even for a clone: you have to source the aspeherics, the ED elements etc. I don't believe you can do that for this price, even with no design costs. And also, why would you clone a both complicated and niche lens like an ultra wide macro? I think either the factory that makes them has made extra and sold them on (in which case they deserve a serious kick in the a**) or else Laowa sold off excess optical units themselves, not expecting them to end up being sold cheap on the international market (which may or may not be allowed under the terms of such sales).

IN any case I hope Laowa gets legal satisfaction if any of the scenarios where either the factory breached their contractual obligations, or the purchasers sold on where they weren't supposed to, or if indeed it does turn out to be copied.

But without knowing exactly what happened, I reckon anyone who wants to buy one of these can do so with an easy conscience.

I agree that we don't know the full story. What I wrote above came from Venus themselves when I asked about the Opteka story.
At the end the customer benefits (and definitely should buy these in good conscience).
My point was that relative small companies like Venus would not survive is this keeps happening to their line-up.

That's undoubtedly true; if these are strainght rip-offs of Laowa's IP as they claim (they say that their 65mm macro has been cloned too) and it keeps happening they won't survive. In fact if I was sure this was true, then I wouldn't buy one (although I wouldn't think it wrong for others to; in the end it's up to the legal system to stop it and freeze sales). My comment was just that I think something funny must be going on, because of the oddness of a weird lens like this being the target of cloners plus the other things I said. Wound't they go for a more mainstream Laowa? Their comment that "we never sell lenses we make under any other brand but our own" seems oddly precise (though it might be a translation issue). It doesn't, for example, exclude having sold on lenses for other people to sell under a different brand, and then thinking better of it....

But it's be really interesting to find out what happened. And if these really are clones with copied design, I'd love to know *why* they chose this design to copy!

Your test image is impressive and it's a steal at USD149 so I have to admit I was briefly tempted. But my "no lenses wider than 28mm or longer than 90mm" prohibition kicked in and I was able to resist.

Another sample from this interesting lens
(by the way if you think you'll use it a lot, you might be better off with the Laowa original which I think is likely to have a more durable helicoid)

Having lived in China I can give you other options knowing how the following situations often occur. In al cases Designer outsources to Factories A, B and C with copyright restrictions in place.

Situation A.
Manufacturing goes ahead but without complete control of the factory and production process by the designer (see : Apple for how this is done, even then it's not 100% successful) some of the production can easily be diverted (e.g. maybe they are supposed to run two shifts before changing moulds, but run a third with the products diverted, or maybe they are supposed to use moulds for 2 weeks before replacing and destroying, however the moulds are instead sold not destroyed.

Situation B
Designer breaks contract with Factory B who then goes on to produce a 'new line', renamed and sold as a competing product.

Situation C
Factory C copies designs and formula and sells to a competitor of the designer.

In all cases cosmetic changes are made before the new competing product is launched and in China proving copyright trespass is very difficult (though they've greatly improved in this regard, especially with disputes between two domestic companies).

And so on. There are so many factories, and often a lack of supervision and control, in China that any of the above scenarios (and many more I'm sure you can now envisage) is feasible. Opteka make some fine products that are far more reasonably priced than the 'originals', they are usually careful to copy products that are difficult to prove copyright to, although this one may see them pay a heavy price if transgression is proven.

True Story (from a lecture I attended in Shanghai on Copyright Transgression).
Unilever had some lorries (trucks), direct from their factories and in collusion with the drivers, diverted to a factory (less than 20kms from Unilever's) making copy Unilever products, where the originals were unloaded and sold off separately whilst the copies they made were loaded up on Unilever's own lorries and then delivered to major supermarkets 'direct from the factory' ! They were caught when Unilever hired a Western industrial detective to investigate how the fakes were being delivered to the stores..

Actually in the light of @frogfish comments, in which he says that one of the scenarios I envisaged (the factory, not thoroughly controlled by the designer company, makes extra copies of the core components and sells them off illegally) is actually quite common, I'm inclined to believe that, or something like it, the most likely explanation.

While it was hard to believe anyone would reverse engineer such a complex and niche lens, it also would be very stupid of Laowa to sell off excess and then complain.

Far more likely that the core optical units come from the same factory, illegally diverted. It'd be good for Laowa to tell us more. If this is true, and I'd known it to be true, I don't think I would have bought the Opteka.

Just got this lens. Im new to macro and so far I like it. The focusing ring is kind of tight but other than that so far so good.

@DavidBM,
I got curious after seeing your images and just tried the 'Laowa 15/4 Macro' version this lens. Although it's 1:1, the front element almost has to touch the subject for that to work. Because of that, I think the 1:2 distance may be more practical. (and safer to use)

I found that adding a 10mm tube to my Laowa 15/2 puts me in 1:1 territory the same way but with the advantage of better LoCA correction and wider aperture.

But wouldn't that change the focal length and aperture as well? How is the real angle of the macro lens compared to a regular wide angle paired with an extension tube?

David knows more about extension tubes but as far as I know, extension tubes increase lens "magnification" by an amount equal to the extension distance divided by the lens focal length. In theory it should not affect "focal length" although many macro lenses reduce effective focal length when getting towards macro.
.
The lens's effective f-stop aperture also increases depending on the extension amount. Keep in mind that the same also happens with dedicated macro lenses.

That's my understanding too. I certainly am using it mainly around 1:2 and a little more.
Sounds like a good solution Fred, though @BastianK (who also has been using the 2/15 for closeup work) and I did have a bit of too and fro, though, about resolution, and though we weren't comparing similar images we had the impression that the macro version has notably better off axis resolution at comparable apertures and magnifications than the 2/15. Though much more distortion in the macro version. Still if macro isn't the prime reason for getting a Laowa 15 then the 2/15 used occasionally with tubes is likely the go.

Yes agree. When adding a 10mm tube to the 15/2, you have to almost touch the subject for 1:1 as well.
Small extension amounts produce big magnification results on ultra wides but the downsize is having to be too close to the subject.

What surprises me actually @Fred Miranda is that the extension tube permits you to focus at all. On most ultrawides that I have used the shortest commercial tube puts the *furthest* focussing distance *behind* the front element.

That's why there is a cottage industry of shaving down tubes to 5mm or so.... It must be something about the design of this lens that makes it possible!

I'm allowed to focus but it's pretty much unusable almost touching the front element...

Love the last image. Do you know what's its magnification? it looks like a bit closer than 1:4.
