In addition to the 35mm and 50mm lenses, Yongnuo also has a Canon 2x teleconverter clone that sell for less than half of the price of the original Canon version. Here are the specifications:
Yongnuo products are currently available for sale at Amazon, B&H and eBay.
This is really becoming hilarious. Let’s hope all their clones beat out the OEM equivalents, just embarrass the crap out of their lazy asses.
Sometimes what we need is a kick in the butt to move forward, it’s canon’s turn.
In all likelihood these ARE the “OEM equivalents” but with cosmetic changes.
At any rate, this embarrassing indeed but not for Canon.
actually the lenses are with different lens arrangements, despite the similar cosmetic look, giving different image (even better the the Canon equivalents).
So no, they arent the same, I wouldnt think this would be the same as the Canon TC either.
How do you know that? I’m trying to find a diagram for the Canon 50 f/1.8 II to compare to the one Yongnuo has on their web site but I’m not having much luck finding it…
Actually nevermind – I found some diagrams:
Canon 50 f/1.8 II: http://aflenses.ru/id/800
Yongnuo 50 f/1.8: http://www.hkyongnuo.com/s-detail.php?ID=356
Canon 35 f/2 non-USM: http://aflenses.ru/id/787
Yongnuo 35 f/2: http://www.hkyongnuo.com/s-detail.php?ID=359
The diagrams look identical to me. Nevertheless, I’m not an optics expert so if these are significantly unique designs I’m curious as to how…
read, the guy dissasembles the lens and finds it quite different.
Construction is different but the actual optical formulas seem identical.
Nope, they’re not, and it is embarrassing for Canon.
It seems they are mechanically distinct but optically similar to Canon’s lenses. Perhaps the designs are based on expired patents.
From this review which disassembled them (provided to me by JoeNoName below) – http://petapixel.com/2014/12/25/first-review-40-yongnuo-50mm-f1-8-nifty-fifty-clone/ :
“There are some similarities in the glass elements, but the overall construction is quite different.”
Also see the optical diagrams:
Yeah, but if you look at the comparison of the 50mm’s, you can see how they are different in real-world image comparisons. For the most part, the Yongnuo is actually better:
That’s probably because the Canon is unchanged from the film era, but Yongnuo was updated for digital (glass stack before sensor).
We’re laughing now but in 5 years we’re all mocking each other for having a Nikon D5xs or Eos 1HDxrs MkIV instead of the awesome YongNuo 88TMD pro hires body with 105 AF points, 64mp, 19fps and quadruple card slots…. Remember how everyone was laughing at RED a decade ago..?
I love China 中国
I guess this is what happens when you don’t release new products and still sell old stuff as latest and greatest… your patents expire and you get copiedby Chinese legaly.
