  • Man, these been in the rumor news a lot now.
    I think we get it by now. Though, I’m not going to get them.

    • I know, I was first to report about the lenses. The purpose of this post is the specs of the lenses – I did not publish them before.

  • HD10

    Thanks Peter for posting the specs.

  • Zos Xavius

    Even if these are only half decent for the price they will be great for amatuers looking expand their systems.

  • Azmodan

    Looks like a few of those weight specs have decimal points in the wrong place. 0.6ounces is not 275g, 1 ounce is 28.35g, so 275g is 9.7 ounces. The only correct weight specified in ounces is the last one, where indeed 14.1 ounces = 400g

    Don’t know. I might buy them if they were made by a company that’s willing to wear a free liu xiaobo t-shirt.

    • Zos Xavius

      They cremated him 2 days ago. Sad.

      • BdV

        Yes, very sad.

    Copper core? What’s this? Cookware?

  • Stephen Roberts

    Does anyone know if the fisheye is circular?

  • Markintosh_x

    Give it German name plus brass–like body and you can start to sell them around $2000:))
