Canon CN-E 14mm T3.1 L F Cinema Prime Lens In Stock And Ready To Ship

Canon CN-E 14mm T3.1

B&H has the Canon CN-E 14mm T3.1 L F Cinema Prime Lens in stock and ready to ship for whooping $5,220 (click here), but then: this is a high grade professional cine lens.

The Canon CN-E 14mm T3.1 L F Cinema Prime Lens is an ultra wide-angle prime lens for the full-frame sensor format, which makes it an ideal lens for the Cinema EOS series and all Canon DSLRs. The maximum aperture is T3.1, and the 11 blade iris ensures beautiful, rounded bokeh. The lens features markings on both sides of the barrel, making it easy to read settings from behind or on either side of the camera. In order to make lens changes quicker and easier, the 14mm T3.1 is designed to share similar dimensions with other CN-E lenses.

Update – Canon EOS M w/ 22mm Down To $450 On Amazon – Next EOS M Close To Be Announced?

Canon EOS M

Update: it is no longer $399 but $449. Still a bargain.

The Canon EOS M with the EF-M 22mm f/2 STM pancake lens is on sale for just $399 $449 on Amazon US (click here). The EOS M with the 18-55mm f/3.5-5.6 IS lens is on sale for $549 (click here). Great price for a very good performing mirrorless camera with outstanding image quality.

These sales appear to fit with the latest rumor about the next EOS M I reported about a few days ago. The successor of the EOS M could be announced this summer. Is Canon trying to empty stocks?

  • How to reduce the size of the large-aperture super telephoto lens
    • Effective diameter of the first group with the largest
    • I reduce the number of the first group
      • It is necessary to reduce aberration by increasing the number
      • Can not reduce the aberration and reduce the number
    • I increase a refractive power of the first group
      • The thickness of the lens increases, the effect of weight reduction is canceled
      • Impact of manufacturing error is large high refractive index
